Older homes are a lot harder to heat and cool, and even more importantly, there are usually special methods to add central air that need to take place. Nevertheless, it’s important that you know that adding central air doesn’t have to be as painstaking as many people make it out to be. You may even be surprised to find out that your old existing duct-work can be used if you have it, and if you don’t, new duct-work can easily be installed by numerous means to make things a lot less invasive than you would think. In this guide we’ll tell you how to get quality air conditioning in your home so you can get the most out of it as easily as possible.
Choosing the Right Unit
When it comes to the most important and hardest part for you, that’s simply choosing the central air conditioning unit. You need to select the right equipment that is the most energy efficient for your size of home. If you’re choosing to install an outside unit, you need to make sure that it’s a good model and reliable. You want the central air to be able to cool your home without costing you a fortune to run it. Of course, even smaller window unit air conditioners can do so, but these will usually rack up your electric bill a lot more than a central air unit.
If you hire a contractor and they don’t do a manual J load calculation, then you may be paying for a contractor that doesn’t know what they’re doing or doesn’t belong to the ACCA (Air Conditioning Contractors of America). This could also mean that they aren’t licensed properly to do the repairs you need on your home. What is a J Load calculation? This is a way for the contractor to know what type and how much heat gain your home will receive from the outside air, the sun, and more. This is important and can actually help you choose the right size unit for them to install (if you chose one that was inefficient, you can always get the best quality one for your home instead).
Choosing the Right Sized Unit
If you think about it, the weight and conditioner size matters greatly. A one-ton heater equals about 12,000 BTU’s per hour. Therefore, it’s important to know just how big of an area you’re trying to cool overall. It will also help you to decide where to put the thermostat (we’ll talk about that soon). When you don’t have the right sized unit for your home, or if your thermostat is in the wrong place, the air conditioner is going to constantly run more and cost you precious savings you could be earning if you would have gone with a bigger unit that was built properly for your home.
This can also affect whether or not you’re going to need to have it running, what rooms will be the coldest, and much more. Most people have their thermostats in the living room, as that’s the room that they frequent most, but others like to have it in their bedrooms. Or do you want multiple thermostats? Whatever the case may be, make sure you place your thermostat in the right area so you can get the most efficient energy savings, yet still keep your house warm.
It doesn’t cost more than a few thousand dollars to have contractors even come out to your home and install duct-work when necessary. For larger projects, you may need a little more, but for the average American home, this isn’t the case. Make sure your HVAC company is licensed and insured, and that they have experience installing units made for your type of home and you’ll do just fine.
