When it comes time to purchase a new HVAC unit for your home, you want to make sure you get one that is going to do everything you need it to do and more. The last thing you want is to waste money on a unit that isn’t capable of heating and cooling your space. Taking the time to speak with a trained professional will help ensure you get everything you need in a unit without having to go through the process of figuring it all out on your own.
The size and type of your air conditioner depends largely upon the climate and the cooling loads. Evaporative coolers tend to be practical in an arid and hot region, such as that of the southwest. For other locations, a compressor-driven air-conditioning system might be the only choice. As you shop for an air conditioning system, make sure you look at the SEER rating. You want to get one that has a rating of 13.00 SEER minimum.
For those who already have a forced-air heating system, you might be able to tie the A/C unit into your existing duct work. Everything depends largely upon the size of the unit, ducts and the relative cooling and heating loads of the home. Thanks to a good HVAC contractor, you don’t have to worry about going through and trying to do all of the calculations on your own.
To maintain efficiency of the unit, you need to make sure you have the proper size and the installation is completed properly. Too large of a unit will make it difficult to remove any humidity. If you get a unit that is too small, it won’t be able to maintain a comfortable temperature on the hotter days. Improper location of the unit, lack of duct installation, incorrect refrigerant charge and improper duct sealing can all cause the efficiency to decline.
When it comes time to get a new unit, don’t try and handle everything on your own. Let someone who has a solid understanding of what it is that you need get to work for you providing you with a system that can handle the load.
