Heating Repair in Scottsdale
When your heat pump or furnace fails on a 35°F Scottsdale night, you need it back today, not in three days. We do same-day diagnosis across Scottsdale, from Old Town to North Scottsdale's gated communities. Heating calls peak December through February, and we keep slots open for no-heat dispatches across the winter.
Local Roots is family-owned. Chris and Stacia Hays grew up in Scottsdale, both Chaparral High grads, and have been on Valley heating calls for 24+ years. Our techs are NATE-certified, the company is AZ ROC #358833 licensed, and we are EPA Section 608 certified for refrigerant work and ANSI Z21 trained on gas furnace safety.
On the diagnostic, we identify the failed component before we quote the repair. Scottsdale heating calls fall into two patterns: heat pumps where the reversing valve, defrost board, or aux heat strip has failed; and older Central Scottsdale gas furnaces where the igniter, flame sensor, gas valve, or heat exchanger needs work. We show you the failed part either way.
Call 602-560-8989 to get a tech routed to you. Diagnosis is free when you book the repair with us, second opinions are free, period.

Why Scottsdale Homes Need Specialized Service
Scottsdale heating is a heat-pump game. Most homes here use heat pumps that double as AC systems, meaning the same outdoor unit that cools you in July heats you in January. When the reversing valve fails or the defrost board malfunctions, you lose both heating and cooling capability.
Higher elevations in North Scottsdale (Desert Mountain, Carefree, Troon) see colder winter nights than the valley floor, sometimes into the high 20s during Arctic blasts. Older Central Scottsdale homes built before 1995 may still have gas furnaces that require carbon monoxide testing and heat exchanger inspection on every service call.
How the Defrost Cycle Works
On a heat pump, the outdoor coil can frost over in cold, humid air because it sits below ambient temperature while absorbing heat. The system reverses itself for a few minutes (you might see steam rise from the unit), melts the frost, and switches back to heating mode. During the defrost cycle the indoor air handler briefly blows cool air. That is normal, not a failure.
If the defrost cycle runs constantly, if frost builds on the outdoor coil hours after defrost, or if the system drops into emergency aux heat all the time, the defrost board or outdoor sensor has failed. We diagnose at the outdoor unit and replace the board on the first visit when we have the part on the truck.
Aux Heat and Why January Bills Spike
Heat pumps lose efficiency below about 35°F outdoor temperature and switch to electric resistance aux heat to keep up. Aux heat costs three to four times more to run than heat-pump heating. On the coldest Scottsdale nights, this behavior is normal.
If your bill is spiking and the outdoor temperature did not drop below 40°F for long, something else is wrong: a refrigerant charge issue, a reversing valve stuck in the wrong position, or the thermostat calling for aux heat when it should not. Worth a diagnostic before you assume the system is running hard for the season.
Older Gas Furnaces in Central Scottsdale
Pre-1995 Central Scottsdale homes often still have gas furnaces in service. The common failures are predictable: hot surface igniter, flame sensor, gas valve, blower motor, control board. We diagnose with a combustion analyzer to confirm proper combustion ratios and inspect the heat exchanger for cracks (the safety-critical check on any gas furnace, because a cracked heat exchanger leaks carbon monoxide into the house). We carry common igniters, flame sensors, and capacitors on the truck. If a heat exchanger is cracked we recommend replacement, not repair.
Your Neighbors, Your HVAC & Plumbing Team
Local Roots is family-owned by Chris and Stacia Hays, both Scottsdale natives. Chris attended Chaparral High School, Cocopah Middle, and Pueblo and Mojave elementary schools in the Chaparral Park area. Stacia is also a Chaparral grad: Cocopah Middle and Anasazi Elementary. They built Hays Cooling here in 2001 and ran it for nearly two decades before private-equity ownership in 2020. They came back out of retirement to start Local Roots because service quality in the Valley had slipped.
Across 24+ years in the HVAC trade, Chris and Stacia have built deep relationships in Scottsdale's most established communities.

Frequently Asked Questions
Common questions about heating repair in scottsdale answered by our experts.
Ask Us DirectlySame-day on most no-heat calls during heating season. We keep one or two emergency slots open across the December-February peak. Call 602-560-8989 for the honest response window for your time slot, including January cold-snap nights when our schedule runs tightest.
A furnace makes heat by burning gas or running electric resistance elements. A heat pump moves heat from outside air into your home, the same mechanism as a central AC running backwards. Heat pumps are more efficient in Scottsdale's mild winters because outside air still contains usable heat energy down to about 25°F. Most homes here use heat pumps; older Central Scottsdale homes are the main exceptions, still running gas furnaces. We service both.
Not necessarily. On a cold morning, the outdoor coil can frost over and the system briefly reverses to melt the frost. During this defrost cycle the indoor air handler blows cool air for two to five minutes. That is normal. If your unit blows cold for longer than five minutes, or if it cycles in and out of defrost constantly, the defrost board or outdoor sensor has likely failed. Call us and we will diagnose at the outdoor unit.
Heat pumps switch to electric resistance aux heat below about 35°F outdoor, which costs three to four times more to run than heat-pump heating. On a January with a stretch of sub-40°F nights, that is normal. If your bill spikes without an extended cold snap, the heat pump may be defaulting to aux heat for the wrong reason: a refrigerant charge issue, a stuck reversing valve, or a thermostat misconfiguration. We diagnose at the outdoor unit.
Yes. Older homes in Central Scottsdale still run gas furnaces, and we service them all. Our techs are ANSI Z21 trained on gas furnace safety and run a combustion analyzer on every gas furnace call to confirm proper burn ratios. We inspect the heat exchanger for cracks on every service; a cracked heat exchanger leaks carbon monoxide into the house and is grounds for replacement rather than repair.
Yes. NATE certification is the industry standard for HVAC technical competence. Our techs hold it, and we are also EPA Section 608 certified for refrigerant work, ANSI Z21 trained for gas furnace safety, and the company is AZ ROC #358833 licensed and bonded. Credentials matter on heating work because the difference between a misdiagnosed defrost board and a correct repair can be hundreds of dollars wasted and another cold night without heat.
