The adage “Go big or go home” applies to many things, however heating and air conditioning isn’t one of them. The size of your system compared to the size of your home and your heating and cooling needs really does make a difference. Read on to find out why and how to select the right-sized HVAC for your home.

Size and All Things Heating and Cooling

When it comes to the size of your HVAC unit, oversizing and under sizing can affect not only your comfort level but also your energy consumption.

If a unit is too small it has to run more to keep up with temperature demands. This increases energy consumption, increases your utility bills, and causes excessive wear and tear to your HVAC unit. All of this basically cancels out any savings you had up front by buying a less expensive unit, as well as causes temperature inconsistencies in your home.

A unit that is too big will cycle on and off frequently, cooling the air quickly, then shutting off. The main problem with this is that it can’t effectively remove humidity from the air in such short cycles, leaving your home feeling warmer than it should.

Choosing the Right Size Unit

Don’t base the size of a new unit on the capacity of an old one. Since most household heating systems are oversized it’s best to take new measurements and get it right if you’re going to upgrade. The size of the unit is based on a heat loss/heat gain estimate that is based on things such as square footage and floor area to tonnage ratios. A reliable HVAC company can give you the information you need and can take the measurements to ensure you have the right size HVAC unit for your home.
