How Technicians Determine the Size of Your New AC

In order for an air conditioner to work well for a home, it must be properly sized for the home. The installers need to determine how large a cooling load a new air conditioning system must produce in order to keep the home at the temperature that the homeowner wants for comfort.

Sizing is a complicated process. It’s easy for an amateur to assume that the more powerful an AC, the better it will cool a house. However, an oversized air conditioner can be a major a problem as an undersized one: it will lower the temperature so rapidly that it will shut off the cooling cycle before completing it, only to turn back on a short time later, and continue to repeat the process. This is called “short-cycling,” and it leads to wasted energy and a shortened lifespan for the system.

How Sizing is Done for an AC

The way that technicians find out the cooling load (in tons) an air conditioner needs to supply to both keep a house cool and not to short-cycle, they perform a heat load calculation. This complex calculation collects data about the house to determine how well it traps heat and keeps heat outside. The more heat that stays inside a home, the more powerful an AC is needed to combat it.

The basic part of the heat load calculation is the volume of the house; square footage along is enough to determine how much space the AC must cool down. The technicians then analyze other parts of the home to see where heat is entering and where it is being generated.

Heat can enter a home through poor insulation, especially in the attic, so the technicians look over the insulation in the walls and ceilings. They also factor in the number of windows and the directions they face to see where radiant heat is entering the house.

Technicians look over the number of heat generating appliances in the house and how often they run: washing machine, laundry machine, oven, entertainment center, lights, etc. The number of people regularly in the home also affects how much heat is inside it.

Once the technicians have gathered all the pertinent data (and there’s even more than we’ve listed here), they can plug it into the calculation and return with the amount of cooling load necessary to keep the home comfortable.

The heat load calculation is one of the many reasons to rely on professionals for your air conditioning installation in Brentwood, PA. The only way to receive the right AC working at its best is to leave the job to the experts.
