Local considerations
Most homes heat with a heat pump, so winter faults are defrost boards and reversing valves rather than gas burners. The result for Flagstaff homeowners is that a heating system that barely coped last winter may not cope at all this one, once a component has drifted slightly further out of spec.
Most homes heat with a heat pump, so winter faults are defrost boards and reversing valves rather than gas burners. In Flagstaff that makes the heating season a test of whatever deferred maintenance the summer covered up. Equipment that held on through a mild spell often cannot manage a sustained cold stretch.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
- Urgency
- Call today
- Read next
- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Flagstaff HVAC questions
Why does my furnace smell when it first runs?
A brief dusty smell on the first run of the season is normal as dust burns off the heat exchanger. A persistent burning smell, or any electrical smell, is not. Shut it off and call.
What if I smell gas?
Leave the building first, then call the gas utility or 911 from outside. Do not operate light switches, thermostats or phones on your way out. Call us afterwards, once the utility has made the property safe.
Why are my upstairs radiators cold?
Usually trapped air or a circulation problem rather than a failed boiler. Bleeding radiators resolves some of it. If pressure keeps dropping after bleeding, there is a leak somewhere in the loop worth finding.
How do you decide which provider gets my call?
By ZIP code first, then by who is accepting calls. We publish no ratings and sell no placement. During a cold snap the set of available providers in Coconino County narrows considerably.
Do you send your own technicians to Flagstaff?
No. HVAC Emergency USA is a referral service that connects homeowners with independent local providers. We do not own trucks, employ technicians or carry out work. Verifying licence and insurance before work starts is your responsibility.
