Frequently Asked Questions
When should I have my HVAC system serviced?
You should have your heating system serviced before the cooling season and your cooling system before the heating system. If you have a system that both heats and cools, like a heat pump, it is recommended that you get professional service between the heating and cooling seasons.
Is good indoor air quality important to your home?
In short, indoor air quality is far more polluted than outdoor quality. These pollutants include allergens, dirt, mold, and much more. These contaminants affect your family’s health and, sometimes, sleep. Installing an air cleaner, purifier, or scrubber can improve your home’s air quality.
How often should I change my system’s air filters?
Air filters should be replaced at least every 90 days. However, you should replace your filters more often if:
- You have more than two pets that shed fur
- Someone in your home has respiratory issues
- Your home is in an area that has more allergens
