HVAC Questions Answered
Frequently Asked Questions
- How often do I need to change my air filters?- Once a month is a pretty good rule of thumb for most people. Depending on where you live and how much dirt, pet dander, and other contaminants are present, the answer could be more or less. Check your filter frequently to determine if it’s dirty. If it is, change it. 
- What size AC unit do I need?- There’s no easy answer for this one. A lot of factors will go into what size heating and cooling unit you’ll need. The type of house you own, its walls, insulation, attic space, and more can go into determining what size unit is required. A system that is too large could result in a home that’s too humid, causing problems with moisture and mold. A system that is too small will run constantly, running up your energy bill. Only a qualified heating and cooling technician can determine what size unit is best for your home. 
- Should I cover my AC unit in the fall and winter?- While covering your unit can prevent unwanted debris from accumulating on the unit, it can also cause problems if you try to operate it with the covering in place. If you’re going on a long trip and plan to turn the unit off while you’re gone, feel free to cover it up. Just make sure you disconnect the power source before leaving. 
- Why should I replace my R-22 outdoor unit with an R410A?- R-22 refrigerant and equipment are being phased out as Montreal Protocol regulations intended to reduce the impact on ozone take hold. As time passes, replacement parts and refrigerants for old R-22 units will become harder to find and more expensive, so replacing your unit now can save you some headaches in the future.
