You might think that buying a new HVAC system in Lake Zurich, IL, is simple; just determine how much you can spend, and pick the most efficient system that fits your budget. But the size of the system also matters, both to your comfort and your bills. Here is a look at the importance of getting a properly sized HVAC system.

How to Determine the Size You Need

Determining the correct size of HVAC system for your house involves more than just dividing your home’s square footage by a rule-of-thumb number. You also have to take into account your home’s layout (two floors or one), insulation (more is better), the number of south-facing windows or walls (more mean more sun and heat gain), and any shade that your house gets from surrounding trees. All of these factors contribute to a more accurate picture of exactly how much heating or cooling you need.

Don’t Go Too Big or Too Small

An air conditioner that is too small for your house will run all day and never get your house cool. You might think that a smaller unit might save power and thus money on your bills. However, a system that has to run all the time will eat into those savings.

On the other hand, an AC system that is too big will turn on, cool the house quickly and turn off, only to have to turn back on in a short time. It will not be on long enough to dehumidify the house either. An air conditioner uses more energy when it first turns on to get cold than it does to run once it is cold, so this constant on-and-off cycling also wastes money.

Leave It to the Experts

An HVAC professional uses a specific formula to determine just how much cooling you need. Consulting with an expert to help you choose your next HVAC system will save you money, both upfront and in the long run.
