Size Matters: How AC Technicians Choose The Ideal Unit For Your Home

As temperatures rise each summer, you might realize that the heat and humidity simply aren't for you. As you take the time to select the perfect air conditioner for your home, it is important to note that not all units are created equally. Selecting the perfect size for your air conditioning unit means that your home is kept comfortable throughout the year. Speaking with an AC technician to determine the proper size for your home is essential.

Important Sizing Factors

The first step to determining the proper size for your cooling unit is to talk to your HVAC technician, such as at Long Beach Heating & Air Conditioning Inc, about the insulation in your home. A poorly insulated home will allow air from outside to affect the interior temperature more than it should.

Your technician will also determine how the house is situated on the lot. If you have many windows facing the sun throughout the day, you are bound to have a warmer interior than other homes. This impacts the efficacy of an AC unit. The number of windows is also relevant, as additional openings to the home influence the unit's ability to efficiently cool down the home.

Technicians will determine the latent cooling load of your home, which is the amount of energy it will take the unit to eliminate humidity from the air. You raise the level of humidity inside your home by performing everyday activities, including bathing and opening the door.

Your technician will also need to know your sensible cooling load, which refers to the amount of energy it will take to rid your home of heat. This is the amount of energy it takes to maintain the desired temperature inside your home. Your HVAC technician will arrive at this number by taking into account the average temperature outside as well as how many entrance points will allow heat to enter the house.

Using both of these figures, your technician will then determine the cooling load of your house. This also factors in the average of the highest recorded temperatures in your area.  With this information in hand, your HVAC contractor will recommend a unit of the appropriate size.

Arriving at the ideal size for your AC unit is tricky. This is why it is important to trust a professional. A unit that is too small will not perform correctly, keeping rooms too warm because they don't run as long as they should. A unit that is too big will lead to a higher energy bill that simply doesn't lasso in the humidity as needed.
