Central Air
Central Air Conditioners
So you have decided to buy central air conditioning.
Almost eighty percent of the new U.S. houses are installing central air conditioning units while construction. While it may not have been necessary to have air conditioning several decades ago, it is quite uncomfortable not to have it now. But those having existing homes do not need to worry, as the central air conditioning units can even be set up in houses that have already been constructed!
If you are looking for the best central air conditioning unit, you need to keep certain points in mind.
The best way and most important thing when buying central air conditioning equipment is to have it installed by a qualified contractor.
When one talks about saving money through efficient air conditioning systems the topic of SEER usually comes up. SEER or seasonal energy efficiency ratio, rates the central air conditioning unit. You can actually save quite a lot in your electricity bills if you substitute your old and ineffective air conditioner with a new SEER rated central air conditioning set up. Heating, ventilation and air-conditioning (HVAC) manufacturers are responding to the challenges of increased energy costs by offering homeowners air-conditioning units that deliver new energy efficiency standards and reduce your energy usage.
Always consult a specialist engineering company, who will specify, design and install the correct air conditioning system for your needs. There are many reputable contractors specializing in the installation of air conditioning systems for both small and large homes. Large houses usually require a centralized air conditioning system and its installation is more complicated and labor intensive. There are various kinds of air conditioning systems depending on your needs, your home size and your budget.
Choosing Your Air Conditioner And Installer
There are a number of reasons why you should go for central air conditioning.
It is the most effective way of heating and cooling the entire home because it can supply the conditioned air directly to the rooms whether the internal doors are open or closed. Having said that, which brand or manufacturer should you consider? Good question, but in reality it depends on your budget and your expectations. It would be recommended that you retrieve at least 3 quotes from reputable businesses (not outlets like Home Depot) which specialize in air conditioning supply and installation.
These companies will have ties to certain manufacturers and as a result will push a brand they will make more money from. But if you are aware beforehand which brands you are interested in you will be more assured of getting a good deal on a system you have chosen not what they want you to have.
The back yard is the most common place to find a central air conditioning unit condenser unit (outdoor section). This information is important because a house's structure, window area, sun exposure, and climate will affect your central air conditioning needs. Again this is where you need specialist guidance from experienced installers. Make sure they look all over your home checking each room you want diffusers (ceiling outlets) in and note whether they check out the ceiling space, this small check is important as seasoned quoters / installers with experience will tell you that some ceiling spaces do not accommodate the ducting very well and can cause all sorts of difficulties during installation, you do not want the installer cutting corners (so to speak) trying to fit ductwork.
The electrical load on your home will be increased dramatically as a central A/C system is a large electrical user, some homes cannot accommodate this requirement and therefore need to have their mains upgraded. This can significantly increase the installation cost.
Maintenance Of Your Air Conditioning System
For your home central air conditioning system to last as long as possible, proper maintenance is a must. You probably recognize - as most homeowners do - that keeping your heating and air conditioning units running well is important. We tend to take our air conditioning for granted, and wonder how we ever got along without it, but we rarely check the system until it begins to blow out hot air.
Proper care of your air conditioning system like scheduled cleaning will also make it more efficient for a long time. If you have central air conditioning, it is important to keep the outside compressor compartment (condenser) as clean as possible. And of course the indoor return air filter must be kept clean also to improve the air flow throughout the home. There are not really many things the homeowner must do to keep their A/C happy other than cleaning and keeping the outdoor condenser free from debris and plant foliage.
If you do these you should receive many years of faithful service from your new central air conditioning system.

What size window air conditioner should I get to supplement my central air?
We like to cool our bedroom more than the rest of the house. We want to get a portable air conditioner, but should we get the size for the room or just a small unit to cool the room an extra few degrees. This room is at the far end of the house from the central air unit and the thermostat. How do we figure the BTU's for this situation?
When selecting HVAC units one of the things you want to avoid if possible is oversizing the unit. The reason for this is that a compressor cycling on and off a lot is going to fail sooner than one that runs more continuously. You'll also be paying for the larger unit when you don't need to. With that said, in your case it's too difficult to be worth trying to calculate the actual load you need to meet in order to bring your bedroom down a few degrees. However, based on experience I do know that a few degrees difference will not require much extra load at all. Since your central system will keep running normally it will take less than 3000 BTU to give that little extra cooling you want. I'm pretty sure they don't make them that small though, so just find the smallest one available and set it to the temperature you want.
FYI, a decent 1800 sq ft house will usually have about a 36000BTU capacity unit. Unless you have a big house, an 18000BTU unit would be enough to cool half your house all by itself--major overkill for supplementing one bedroom with existing cooling.
