Question Answer

Frequently Asked Question Customer Based Service

Make sure to check back soon because the HVAC FAQs page will be updated regularly—and  contact us if you don’t see your question here!

Your HVAC systems should be serviced before the start of each heating and cooling season. So, your air conditioner should have regular maintenance performed at the end of winter or beginning of spring, while your heat pump or furnace should have its regular maintenance performed at the end of summer or beginning of fall.

Your air filters should be replaced every one to three months depending on usage. This is vitally important to the performance of your HVAC systems and your indoor air quality.

The short answer? So important! Your indoor air quality can be as much as 100 times worse than the outdoor air. That means pollutants, allergens, dust, and mildew can be circulating in your home affecting your family’s health and wellbeing. Improving and maintaining your indoor air quality is vitally important to your home and family.

Did you know that when the summer heat beats down on your roof the attic can reach up to 150 degrees? Having attic ventilation can help control moisture, keep cooling costs down, and prevent the accumulation of mold and mildew.

Installing a programmable thermostat in your home helps you take control of how much energy you use for heating and cooling. If used effectively, a programmable thermostat can help you improve energy efficiency and save money on your utility bills.
