Why Sizing Your New Air Conditioner Is So Important

Among the preparatory steps for installing a new air conditioning system, one of the most crucial is sizing the system, i.e. finding out how powerful a system is necessary to provide the ideal balance of cooling. Sizing a system requires the work of technicians familiar with performing heat load calculations. This isn’t a task to leave to guesswork, because the consequences of putting in an air conditioner that’s too small or too large are extreme and usually require replacing the system entirely.

When you want to start your air conditioning installation in Fair Oaks, TX right, call the contractor with more than a quarter of a century of experience matching people’s home with the ideal AC: Cowboys Air Conditioning & Heating. We are 100% committed to your satisfaction.

The problems of an air conditioner that’s too small

If you end up with an AC too underpowered to provide enough BTUs of cooling for your home, you will end up with inferior comfort. In order for the system to reach its expected level of cooling, it will need to run almost constantly, wasting energy and aging its components rapidly. Even then, it’s unlikely that the air conditioning system will have the power to cool down your entire house, leaving you with warm spots and a general weaker level of cooling.

The problems of an air conditioner that’s too large

Homeowners often make the assumption that an air conditioner cannot be too large. It makes sense that an AC can be too small, but how can a system that’s too powerful create a problem? Can’t you just put it on a lower setting?

However, when an AC is too large for the house it’s supposed to cool, it can cause as much trouble as one that’s undersized. An oversized air conditioner will so rapidly cool down a space that the thermostat will turn off the compressor before it can finish its full cycle. A short time later, it will turn it back on again, then turn it off again, and so on…. This is called “short-cycling,” and it creates an immense waste of energy (activating the compressor requires more electricity than any other operation) and puts inordinate stress on the compressor and the other components, shortening the system’s life.

Professional sizing will find the right air conditioner for you

When you bring in an installation team of licensed and seasoned professionals, they will perform an extensive heat load calculation for your home to determine how it traps and keeps out heat. This will give them an idea of the amount of cooling in BTUs an air conditioner must provide to reach your desired level of comfort.

Our team at Cowboys Air Conditioning & Heating will handle your air conditioning installation in Fair Oaks, TX so that you end up with the perfect system to keep you cool for many Texas summers.
