Why Should You Choose Central Air Conditioning? Here are top tips!

Type of air conditioning system

The two mоѕt рорulаr are; Central air conditioning and room air conditioning.

Central аіr соndіtіоnіng cools уоur whole house by circulating аіr through duсtѕ that are іnѕtаllеd within your home. The hot аіr from your home іѕ pulled through thеѕе duсtѕ in оrdеr tо bе trаnѕfоrmеd іntо соld air. Onсе thе air іѕ соld, іt іѕ thеn рumреd bасk dоwn thе ducts and сооlѕ your home. The duсt ѕуѕtеm іѕ bаѕеd on a system оf supply and return.
Rооm аіr conditioning, bеttеr knоwn аѕ window or wall аіr соndіtіоnеrѕ, саn оnlу cool a certain amount of ѕрасе. The unit іѕ mоuntеd to thе wall оr wіndоw of a ѕресіfіс rооm. The plus ѕіzе tо wіndоw air соndіtіоnіng is that unlеѕѕ іt is not a lаrgе unit іt dоеѕ nоt need іtѕ оwn, mоѕt of thе air conditioners wіll рlug rіght іntо a power оutlеt in уоur home.

Air Conditioning Repair Sign

When your heating, ventilation, and air conditioning system is first installed, it’s in mint condition and ready to work for you! However, as the months and years wear on, that same system needs some tender loving care if it is to continue to efficiently heat and cool your home. What needs to be done to keep an HVAC system in good repair?

How to Prepare for a Typical Check Up

To ensure that your home is being heated and cooled correctly, the thermostat settings will need to be checked. If you’re away for most of the day, you can save on your energy bill by allowing your home to become a little cooler or warmer than comfortable and programming it to come to a comfortable temperature around the time you come home in the evening.

Electrical connections also need to be checked and tightened. You’ll also want to measure the voltage and current coming from the motors. Keeping the electrical components of your HVAC system in good repair will ensure that your unit operates safely and lasts as long as possible.

All moving parts will need to be lubricated. Since friction causes excess heat and sucks up energy, lubrication keeps your unit running safely and efficiently.

When your air conditioner runs during the summer, condensation can build up and drain from the unit. You’ll want to ensure that the condensate drain is clear of debris. If it gets clogged, the water can overflow into your basement or closet, causing water damage and increasing indoor humidity levels.

Run a system start up and shut down to ensure the unit works properly. You should be able to go through an entire start up, a few minutes of operation, and shut down without a problem.

How to Prepare for a Cooling-Specific Check Up

It’s best to get your air conditioning system checked in the spring before the hot weather hits, rather than waiting until problems crop up in the middle of the summer. HVAC companies are also more readily available in the spring since they haven’t started responding to very many emergency repair calls.

• To keep your cooling system running smoothly, your evaporator and condenser coils will need to be cleaned. Dirty coils decrease your air conditioner’s efficiency, costing you extra money to keep your home at a comfortable temperature.
• Check the refrigerant levels. The correct amount of refrigerant will keep your system efficient and cost effective.
• Keep your blower clean and free from debris. This will ensure that air will move correctly through the system, keeping your home comfortably cool.

How to Prepare for a Heating-Specific Check Up

Get your heating system checked during the fall to avoid going through a winter’s snowy day without heat. The primary components that need to be checked are the gas connections, gas pressure, heat exchanger, and the burner combustion. If everything is working as it should, you can enjoy a safely operating HVAC system that creates a warm toasty home during the cold winter months.

Cost of Maintaining Central Air Conditioning

The lazy days of summer can actually be quite unbearable if you are one of those who are unfortunate to not have installed a central air conditioning unit to cool the rooms of your house. There’s worse news as it can be quite pricey to cool your home especially in certain cities of the country. Compounding this bad news is the rising cost of electricity. Luckily there is good news — with a few minor adjustments, you can cut your central air conditioning cost.

If you use your central air conditioner correctly, as an educated consumer, you will be able to significantly lower your central air conditioning costs. If you keep your costs low enough you will see that central air is not an unaffordable luxury but rather a way even everyday people can be comfortable and productive in their own homes.

Lowering Cost

The easiest way to lower your central air conditioning costs is to purchase a central air conditioning unit that has a SEER rating of approximately 13 and above. Experts will tell you that if you decide to purchase an inexpensive central air conditioning unit you will discover your savings’ at the front end will eventually be lost as your central air conditioning costs will be higher. Purchasing central air with a higher SEER rating will end up saving you money as time goes on.

Regular Maintenance and Cost Reduction

Another simple way to lower your central air conditioning cost is to provide regular maintenance for your central air conditioning unit. To do this you will need to replace and/or clean the filters regularly year round and monthly in the summer. You should also have routine maintenance for your central air conditioning at the beginning of the hot, summer season – the earlier the better so you don’t find yourself in the middle of a heat wave with no way to cool off. You should also prepare the unit for winter by covering it or placing it in storage during the cold winter months.

Replacing an Old Unit

If you have an outdated unit you may consider replacing it with a more modern central air conditioning unit. The replacement cost may be recouped in a few short years by your lower utility bills. Units older than 10 years are great candidates for replacement.

Get a Licensed Installer

Installing central conditioning is the job of a licensed and insured contractor so include the price of this in your central air conditioning unit costs. Luckily there are many air conditioning installers in the marketplace; they may be called HVAC specialists that can install central air conditioning at a reasonable cost.

Central Air Conditioning Unit

Central Air Conditioning Unit

Obviously, the main purpose of investing in a central air conditioning unit is to cool the rooms of your home and/or business. But did you know another great benefit of central air is its ability to dehumidify damp air – this is a great bonus in localities with sultry climates. You have two choices when it comes time to install your central air conditioning unit –
  1. You can select a self-contained cabinet,
  1. Or a split system.

Besides these two main options, there are a number of features different central air conditioning units have that you can choose between. For example, there are permanent models and small, temporary models that you can simply set in a window and plug in. The permanent models are generally more expensive and require professional installation; however, they are very effective and can cool a home or business so efficiently you may need to wear a sweater even during the summer months. Obviously, not having either type of central air conditioning unit is much worse than not having one so even a small unit is better than nothing.

Currently, approximately 80% of Australian households benefit from the luxury of central air conditioning systems. The main reason for such high number of central air conditioning units is, in addition to temperature control and dehumidifying, that they can have excellent filters that are very beneficial for children and adults that are asthmatic or have other air-borne allergies. If you don’t already have central air, there is good news…central air conditioning units can be retrofitted into existing homes.

Choosing the best unit for your home will require a few measurements because different units are better suited for different sizes of homes. Luckily, there are several different sized central air conditioning units available so you will be able to get proper cooling and dehumidification benefits. You want to make sure and get the proper unit; too small and too large can both be a problem. The best way to do this is to hire an expert contractor. These skilled professionals are trained to calculate the proper size of central air conditioning unit for your home. They use a formula known in the business as “Manual J”.

You will also want to determine the SEER (Seasonal Energy Efficiency Ratio) rating. This number should not be lower than seven or eight, the number can also go as high as 13. Find a unit that employs Scroll™ technology in the compressor and check the Energy Star rating to find out in advance how much electricity your central air conditioning unit will consume.

There are many ways you can lower your electricity costs if you do your research and purchase the proper central air conditioning unit for your building. A unit with a high SEER rating will save you money over time.

How to Enjoy Air Conditioning While Staying Green

The air conditioning industry is a world leader when it comes to staying green. For years it’s worked hard to reduce the release of harmful emissions into the atmosphere from its products, and the improvements made has propelled it into one of the greenest appliance industries around.

However, electric air conditioning units still use power, energy that isn’t necessarily required. There are ways of staying green whilst still using your air conditioning unit, all it takes is a little forethought.

Here are a few tips:

Subsidize

Your air conditioner doesn’t need to be on all year round. Spring and autumn should be tolerable enough without having to adjust the temperature in your home. Try using fans, opening windows or closing curtains to adjust the temperature in a room. Or think about what you’re wearing, could taking off or putting on a jumper solve your problem?

Watch the dial

Don’t be too overzealous with the temperature. If it’s freezing outside that doesn’t mean it has to be warm enough inside to walk around in your underwear. Air conditioning is meant to make a room comfortable, so don’t crank it to the polar opposite of the outside weather. Experiencing rapid changes in temperature could also lead to illness.

Efficiency

Think about the area you want to heat or cool. It’s a simple matter of fact that an air conditioner will not have to work as hard if the area is sealed from other heating or cooling sources. Make sure the doors are closed off to and from the room. Closing curtains or blinds will offset the temperature from outside leaking through the glass.

Read the instructions

Your unit will probably have a guide printed somewhere on it explaining the best temperature settings for each season. Take heed of the advice as it will offer the best options to conserve energy.

Regular servicing

Have your air conditioner serviced at least once a year, twice if you can afford it. Ensuring your unit is in perfect working order before the two big use seasons – summer and winter – will have it running smoother and more efficiently, saving energy costs and improving its life expectancy.

Repair or Replace

Air conditioners being world leaders in lowering emissions means there’s still going to be some old units out there that are perhaps not quite so friendly on old Mother Nature. Air conditioners used to use refrigerants containing harmful HFCs which, as the unit is a closed system, do no damage to the environment – provided there’s no leak. If you have an old residential air conditioner have it checked for leaks. Leaks could be releasing harmful emissions and making the unit as a whole work harder, meaning more energy used and more harm done to the environment. If your old unit is trustworthy and reliable, that’s fine, just keep an eye on it. If not, consider replacing it.

The best thing about staying green is that it usually saves you money as well. Following these simple tips will see your energy bill dropping, but will also keep your environmental conscience on track.

How the Most Common Air Conditioning Parts Work and How to Fix Them

Comfort inside the home is what each and every one of us strives hard to attain. After a long and tiring day outside at work, who wouldn’t want to relax in a cozy and appropriately cool room? Keeping accuracy of the warmth, and more especially the coldness of a room is the role of an air conditioning system. The system is composed of different air conditioning parts which functions according to their purpose. Imagine how troublesome it could be if you realize that there are some problems on your AC unit and the only choice you have is to hire a technician simply because you have no idea how to fix them. This article highlights the most common AC parts, how they work, and how to fix them Generally speaking, the major AC parts manage the movement of air in two main directions: going in and out. Here are the roles of each part:

Evaporator
This part is in charge of receiving the liquid refrigerant. A very important component of an evaporator is the evaporator coil. If the coil is cooled by gas, it cools the air passing through the fins of the evaporator. On the other hand, the heat that passes through the coil continues the cycle of decreasing air temperature. The AC evaporator is one of the most vital air conditioning parts.
The most common problems in the evaporator are as follows:
Unpleasant smell – this is oftentimes due to a build-up of bacteria and mold on the fins of the evaporator. The fins also attract gas (water vapor) from the air, and in turn, condensing down the coil and to the drain. The remnant moisture may stay for too long, causing a build-up of moulds and unpleasant smelling bacteria. To avoid this problem, you may need to clean the evaporator fins every now and then, or coat them with a mold protectant.
Evaporator Frost – this happens when the build-up of moisture stays on the evaporator fins for too long. Water can freeze and coat the blades. It may influence the performance of your AC system. A defrosting can be done during a regular check of your AC unit in order to avoid this problem.
Coolant Issues – If the outward appearance of your evaporator may look like it’s in a good condition, but is acting strangely, there may be a problem with the coolant. If the lines of a coolant have a leak, it may cause other evaporator problems. Asking the services of a technician may be the best option in this regard.

Condenser
The role of the condenser in the system is very important. It facilitates the transfer of heat throughout the other parts of the system. Here are the most common condenser problems, and guide on how to fix them:
If the condenser fan or the compressor won’t run, make sure to check the thermostat to see if it is turned to cool. The setting of the temperature should be lower than the room temperature which is indicated in the thermostat.
Expansion Valve
This part is in charge of regulating the flow of refrigerant to the evaporator. The most common problems that you may face with your expansion valve are flooding, starving, and hunting. The problems mentioned above may be caused by the valve sticking out in the open position. Also, there might be an improper superheat valve settings implemented or an improper location of the bulb. Generally, the troubleshooting that you can do for the expansion valve is limited. In this case, it is much better, and a lot safer, to hire the assistance of a reliable HVAC technician.

Compressor
The compressor is the pump that is used to pressurize the refrigerant. To avoid problems with your compressor, make sure to implement simple checks. The problem may simply be a result of minor faults. Check whether the electrical supply is enough and that the settings are appropriately implemented. Other components such as fans, duct work and filter should be in good condition.
If the internal parts get damaged, the motor windings of the compressor may be burned. Inspecting the overall electrical system regularly will help avoid this problem. But if necessary, you may need an AC compressor replacement.

Caring for your Air Conditioning Parts
Just like any other appliance you have at home, your AC unit needs a regular check-up. Maintenance and occasional repairs should be done to avoid bigger problems to ensue later on. Familiarize yourself with these parts and how to troubleshoot them. However, there are other instances wherein professional help is necessary.

Air Conditioner Freezing Up? Here’s Exactly What You Should Do

The ultimate purpose of installing an air conditioner in your home is to provide a comfortable temperature inside your home. Air conditioner freezing up is quite a natural scenario. At some point, an AC unit may freeze up when the balance between maintaining coolness at home and making sure that the machine is functioning is not kept. When the AC unit freezes up, it is very important to check the flow of air, have the refrigerant carefully checked, and operating it less even in cool weather.

Checking the Air Flow
If your air conditioner starts to freeze up, it is very important to check and make sure that air flow is properly observed. If air cannot pass thoroughly through your AC unit, the tendency is, the coil may freeze. Particles in the air filter may block the flow of air as well. To solve this issue, it is important to check the filter, replacing it when necessary.

The AC coils often freeze up when air flow is restricted
Regularly replacing the filter per the instructions of the manufacturers will prevent it from being blocked again. However, if your air duct system is not large enough to allow sufficient air flow through the coil, functionality may also be sacrificed. Therefore, it is important to have the ducts cleaned especially if the freezing up has started already. On the other hand, if you think you are not able to do the process yourself, it may be wise to hire the professional services of an HVAC contractor. They will inspect the ducts and see to it that the size is enough for your cooling system.

Charging the Refrigerant
Appropriately charged refrigerant can create an optimal environment for the AC unit. If the unit is not accordingly charged, the unit may tend to freeze up. For this task, only a professional AC contractor can charge and check your AC refrigerant. If you have made sure that this is the reason why your AC is freezing up, calling a professional to check on your refrigerant is your next best option.

Temperature Making the Air Conditioner Freeze Up
During the times when the weather is cooler, the air conditioner unit may end up not working well if it is situated outside. If you notice that the air conditioner freezes up lower than 60 degrees Fahrenheit, it is better to call for the assistance of an HVAC professional who will install a control for the temperature. If you are looking for an alternative option, you may also turn the AC unit off if the temperature outside is cool, such as, during night time. Also, it may be best to open windows rather than using your AC unit for cooling.

Check the Blower Fan
Observe intently the movement of the blower fan. It should be transporting the air from the inner vents. If the fan is not working, make sure to stop the unit immediately. At this point, the motor of the blower’s fan may need to be replaced. At the same time, you may need to check all the inner vents of the system in order to make sure that there is no hindrance in the front area of the registers. To check the inner vents, you need to take a look inside. Open all the exhaust vents on your air conditioning system. Closing them will only restrict the flow of air through the coil. It may also be the reason of the freezing of the coil. If the fan operates accordingly and the vents are already unrestricted, make sure to check the outer part of the outer coil.

Other Reasons
If your air conditioning unit is freezing up, it may also be an indication that the coil is already dirty. Dirty coils need to be replaced. For coil replacement, you need to ask the assistance of a professional to do the task. Also, an air conditioning unit may freeze up if the blower has a problem. This too, can only be diagnosed and corrected by a professional HVAC repair person.

Proper Care of the Domestic Heating and Air Conditioning System

[caption id="attachment_341" align="alignleft" width="512"]Caring for Airconditioner Air Conditioner[/caption] As winter approaches, it’s time for your second servicing for your heating and cooling system. You probably think two check-ups is one too many, especially since your budget it tight this year. However, your repair provider isn’t just trying to take more of your money. There is a good purpose for two yearly visits. Remember that your heat pump serves two purposes: heating and cooling. In the winter, the heat pump pumps the heat into your house, and in the summer it pumps the heat out of the house.

  The key to the reason for two visits is temperature. When the weather is hot, you can’t test the heating action of the heat pump, and when it is cold, you can’t test the cooling action. Therefore, your heating and cooling maintenance company will call you twice a year to make an appointment. You have put a lot of money into your system, so it is in the best interest of your budget to keep the system well-maintained. As Poor Richard said so long ago, “A stitch in time saves nine.” That was good advice 200 years ago, and it is still good advice today. If you make small payments twice a year to get your heating and cooling system cleaned and tuned, you will be making small payments to ensure that your system lasts for as many years as it can-rather like a car with 300,000 miles on it.

  In between maintenance visits, you can do your part to keep the system running smoothly and cleanly. The biggest thing you can do is to replace the filter every month. If you buy filters by the carton from a discount store, the cost will be minimal. It is also possible to find permanent filters that can be hosed off to remove the dust. Speaking of dust, a secondary reason for changing the filter is to reduce the amount of dust in the air of your house. You want to eliminate as much dust as possible from your air for two reasons.

  First of all, the dust blown about by your furnace fan lands on your furniture. Dusting the furniture is one of those household duties that most people try to avoid, so if the dust is being trapped by the furnace filter, it’s not being deposited on the armoire. Second, dust in the air aggravates many people’s indoor allergies. We all know the kinds of things that dust is made of, but we won’t go into that here, because it is a rather distasteful topic. These motes flying through the air are not made of dirt from outdoors. It’s made from creepy things that many people are allergic to. So, keeping the room dust-free with a good filter will, in the end, save you money that would have to be spent on allergy-relief medicine.

  These are some of the reasons that you should work to maintain your heating and cooling system. Some of the work is for you, and other work is for the professionals.

Heating And Air Conditioning Systems – How Do They Work?

There are different forms of heating and air conditioning systems and the right one for you will depend on the size of your home, your location and your budget. The most common forms of heating systems are probably the forced air system with the next being the heat pump. Some homes use a water based system while the minority may use resistance heaters. Most cooling systems are either forced air or a ductless split system.

Different systems have their advantages and disadvantages. The average man on the street doesn’t know enough about HVAC systems to work out which is best for his home and it is extremely easy to become confused. That is why it pays to have a company like Hatfield Heating and Air to look after things for you. Not only are you assured that you are dealing with professionals but they take their reputation for providing excellent customer service very seriously. They will review your home and discuss your options with you to come up with the best system for your specific needs.

For example, some people are particularly worried about hvac indoor air quality particularly if their children or they themselves suffer from Asthma or other breathing problems. If this is a concern of yours, discuss it with the heating contractor.
So how do you choose which heating and air conditioning system to install? The most common system is probably the forced air system. If your home already has a HVAC system installed it is probably this one.

How does a forced air system work? Well as the name implies, a fan forces air heated by a furnace through your home via a ducting system. You can easily add an air conditioning system as well giving you an all in one hvac system for your home. They are popular as they are very easy to operate. But they are not particularly environmentally friendly as they can waste a lot of fuel especially if you have neglected to install a high efficiency unit. People who don’t like these systems say that they can spread mold and bacteria but if you keep the system properly maintained and cleaned this shouldn’t be an issue.

A lot of people will use a heat pump system because this is what all their friends have. This is an all in one heating and cooling system so will keep your home cool during the hot summer months and warm in the winter ones. Although if you live in an area with extreme winter temperatures, you may find that you need a supplemental heating system as well. So how does a heat pump system work? It usually is powered by electricity and tends to be energy efficient as it moves the heat around rather than generating it. The system works to heat or cool the house by compressing or decompressing gas. Effectively it is moving heat rather than generating it by taking heat from the warmer location and sending it to the cooler one. If it is the summer then it will be taking the heat from your home and vice versa in the winter.

The performance of the pump is measured by the ratio of heat that is outputted compared to the amount of power, usually electric, consumed. All heat pumps will have two ratings being the HSPF – Heating Seasonable Performance Factor which measures the heating ability of the unit and the SEER – Seasonal Energy Efficiency Rating which measures the cooling one. When you are comparing pumps make sure you are doing so on a like for like basis. You want to aim for the best ratings you can afford but some makes will have a higher rating for cooling air than for heating it.

There are various types of heat pumps and the technology is changing all the time. Your heating contractor will discuss the various options with you and see which would suit your needs best if this is the type of heating and cooling system you want to use. Your contractor will also discuss the size of pump you should get based on the size of your home and also your location as the local weather conditions will have an impact. It is important to discuss your requirements with a heating and air conditioning system specialist as they know the best products on the market and will be able to give you proper guidance.

Regardless of which of the various types of heating and air conditioning systems you decide to install, be sure to carry out regular maintenance to keep it in tip top condition and working at its optimum levels. A poorly maintained system will eventually break down but before that happens; it will cost you more money to run.

Freon Leak Detection

Freon leak detection is not normally a big deal. It is a big deal if you keep adding Freon to your air conditioner every year. Freon is the lifeblood of your home air conditioner. It provides the cooling for the compressor in the outdoor air conditioning unit and it provides the heat transfer in the evaporator coil in your home (the indoor cooling coil). Freon also carries the oil through the system lubricating the internal components of your air conditioning system. No Freon – Means No Cooling in Your Home. No Freon – Means No Lubricating Oil in the Compressor. No Freon – Means the Compressor will over heat.
Those are just some of the reasons to find any Freon leaks and fix those Freon leaks. The price of Freon keeps going up and it is expected to continue to rise. All Freon R22 is recycled. There are Several Methods of Freon Leak Detection
Electronic Freon Leak Detection
Visual Freon Leak Detection
Pressurization Freon Leak Detection
Fluorescent Dye Freon Leak Detection
Electronic Leak Detection
This usually just involves usually a high tech digital sniffer that hunts for the chlorine that is released when the Freon leaks out.  Going over every part of the system, every joint and every weld can find many leaks, but this method leaves a lot to be desired. It is labour intensive and you can receive false positives for Freon leaking.
Visual Freon Leak Detection
This is merely using your eyes and looking for the tell-tale signs of Freon leakage. Freon contains oil and when that oil leaks out it makes a mess. Once an oil leak is witnessed we used a soap bubble solution to visually identify the presence of Freon gas escaping. This does work and it is the simplest low tech way of finding large Freon leaks. It will not find the small Freon leaks. Most Freon leaks are small.
Pressurization Freon Leak Detection
This is an old fashion component replacement method of finding a leak. I think it really is just designed to replace system components rather than identify and repair a Freon leak. This involves cutting the system  apart and pressurizing each component, the line set, the evaporator coil and  the conditioning unit to the same pressures and then waiting a couple of weeks.  Upon return that portion of the system that is lower pressure is the component that is leaking and it can be replaced. This type of Freon Leak Detection is very time consuming. You can except to pay upwards of $500 just for Freon leak detection and then the component replacement and reassembly of the system.
Freon Leak Detection Using the Dye Method
Simple and straight forward. Your air conditioner isn’t cooling because it is low on Freon. A dye is injected into the system with the Freon while charging your system and testing it. The dye is inexpensive
Irrespective it’s better to get your air conditioners checked regularly and maintained properly. You can even read information on reputable sites like http://www.airconperthwa.com.au/ and find out more information.
