Heating Repair in the Prescott Area: Long Winters, More Than One Fuel
Heating here is not a part-time job. NOAA’s 1991–2020 climate normals for the Prescott station show about 28 nights at or below freezing in both December and January, and about 845 and 831 heating degree days in those two months. Phoenix Sky Harbor records about 874 in a whole year. The cold also arrives early and leaves late: the normal low is already 29.8°F in November and is still 31.6°F in March.
Heating fuel varies by town. In the Census Bureau’s 2020–2024 American Community Survey, about 13% of occupied homes in Chino Valley heat mainly with bottled or tank gas, and across Yavapai County about 3% heat mainly with wood. For gas furnaces, UniSource Energy Services, which says it provides natural gas service in Yavapai County, tells customers who suspect a leak not to use the phone, smoke, flip electrical switches or strike a match, and to call 911 and its 24-hour emergency number from a safe location. We repair gas furnaces and heat pumps. Our phones are answered 24/7, and for true emergencies we dispatch a technician between 6 AM and 7 PM.

How many freezing nights does a Prescott furnace work through?
Most of the winter. NOAA’s 1991–2020 climate normals for the Prescott station count about 28 nights at or below freezing in December, 28 in January and 24 in February.

Is a Prescott furnace different from what Phoenix homes need?
Yes. Prescott sits above 5,000 feet and sees freezing temperatures and snow that Phoenix never deals with. Your furnace runs harder and longer through a real winter season. We specifically service cold-climate heating systems, not just desert AC units.
I smell gas near my furnace. What should I do?
Leave the building first and take others with you; do not use switches, phones or flames inside. From a safe location, call 911 and your gas utility’s emergency number. Call us for the repair afterwards.
