Frequently Asked Questions

Should I cover my outdoor air conditioning system in the winter?
Yes. A cover should be placed on your unit to keep out debris. If you live in a snowy climate, a cover also helps keep snow and ice from entering your unit. Preventing fan blade Warping, fan motor gaskets and bearings from moisture damage, as well as coil separation due to freezing and thawing of snow to water and back to ice.

How often should I have maintenance done on my furnace and air conditioner?
Independent and Unbiased Research by Organizations such as: Air Conditioning, Heating, and Refrigeration Institute Found Furnaces and Air conditioners run more efficiently and with far less Mechanical breakdowns when they receive annual maintenance. ** Furthermore All HVAC manufacturers Require Annual Maintenance in order to comply with parts and Labor Warranties.**

What furnace and air conditioner maintenance can I do myself?

- Keep your outdoor unit free of debris, leaves, etc. Be particularly aware of dust and Pollen build-up on the outdoor Coil. Especially during our Cottonwood Season June - July. Rinse coil with garden hose at an Oblique Angle. Rinse down and away from Coil surface. Taking Care Not to drive debris deeper into Coil Fins.

- Ensure that your outdoor unit is on level ground. Also that Outdoor Weather-Tite Electric Wire Whip and Disconnect Box is not Cracked or showing signs of damage or wear.
