A. Once a month for standard filters, pleated filters can generally be replaced every 90 days depending on traffic.

A. Yes, typically HVAC system manufactures will recommend two inspections per year, spring and fall is industry standard.

A. National average for HVAC system life expectancy is 15-years, geothermal systems have an average 25-year expectant life cycle.

A. $125 service call during regular business hours and $185 for after hours, holiday or weekend.

A. The filter will be located at the return air intake or in the furnace/air handler.

A. Spring and fall indoor humidity range should be 40-50%. Winter time range will vary depending on outdoor temperature. If above 20 degrees outdoor temperature 30-35% is recommended. If below 20 degrees outdoor temperature 20-25% is recommended.

A. Yes, studies have shown bacteria, viruses, respiratory infections and allergies are all compounded and thrive in dry environments.

A. Yes, Indoor relative humidity above 55% creates perfect breeding ground for mold, mildew and fungus growth.

A. If you have an emergency heat option on your thermostat then you have a heat pump or a dual fuel system. Most heat pumps struggle to transfer heat when the temperature is 30 degrees or colder. This requires supplemental heat during the extreme outdoor temperatures. Newer systems will automatically engage the supplemental heat when needed and during events where the outdoor range is below 15 degrees it will lock out the heat pump and just utilize the supplemental heat as primary heat. In the event of a compressor failure or refrigerant problem the emergency heat option will allow for heating the home if a failure occurs within the heat pump system.

Dual fuel uses gas instead of the electric resistance heat but same principle of operation.
