Adding Central AC to My Home


With the kind of heat we suffer through these days, it wouldn’t be a surprise if you’re considering replacing your multiple window units with a central air conditioning system. Understandably, there are many considerations before you should act on thoughts that have you musing, “How do I go about adding central AC to my home?”

The first factor to take into account is the cost, of course. Can you afford it? Ask yourself, “By how much will adding central AC to my home set me back?” It will definitely cost you, but do your research. You may just find that the expense is not as steep as you expect it to be. It all depends on how big your home is, whether you already have ductwork, and some other factors.

If you’ve finally decided to go for it, the following are some of the steps you can expect to take in adding central ac to your home.


Choosing a new central AC system

You need to figure out some pertinent details to be able to select the right equipment. Get an experienced and reputable HVAC contractor to determine the heat gain and loss in your home. This process is called a heat load calculation. Don’t be fooled by the label, it’s for heating and air conditioning system as well as other energy efficient home upgrades. This is easy to calculate, strongly influenced by such factors as your home’s location, how much insulation your home has, what kind of doors and windows you have as well as where they’re placed, etc.


Based on the heat load calculation, your HVAC contractor will tell you which AC size in terms of tonnage or Btu per hour suits your home best. Another factor to consider is HVAC unit efficiency. Your contractor will school you on the matter of seasonal energy-efficiency rating (SEER). You want a high SEER because that means lower operating costs, better quality, and more safety features. There’s also the question of which type of unit you should get. There are basically two types: package and split. A split system is the less popular option, but ask your contractor regarding his thoughts on this.

Condensers are noisy, so work with your contractor to figure out the best placement for yours. You’ll want to hide it, of course, but putting it under a deck or enclosing it will lower its efficiency, so find a way to disguise it using your landscape.


Figuring out air delivery

If you already have ducts from your heating system, modifications may be required to accommodate your AC system. These could include upsizing the furnace blower, sealing the ducts, and replacing older supply registers for new ones that allow more air to pass. If you need to add ducts, your contractor will come up with a plan for your ductwork. This means cutting in holes, albeit relatively small ones, for the registers.

With the kind of climate we have these days, a central AC system is a most reasonable solution, so you might as well get it done now so you can enjoy its benefits sooner than later.
