Yes, It Gets Cold Here. We Handle That Too.

Valley winters are short, but a 38-degree January night in North Phoenix finds every weakness in a heating system. We service, repair and install heat pumps, gas furnaces and dual-fuel systems.

Heat Pump Repair and Replacement

A heat pump is your air conditioner running in reverse, which means one system carries the load 12 months a year. That's efficient — and it's also why heat pumps need service twice annually rather than once.

The failures we see most in the Valley are reversing valves that stick after a long cooling season, defrost boards that misread at higher elevations, weak auxiliary heat strips, and low refrigerant charge that a homeowner never noticed in summer but feels immediately in December.

  • Reversing valve, defrost control and auxiliary heat diagnostics
  • Full heat pump replacements with proper backup staging
  • Dual-fuel (heat pump + gas furnace) design and service
  • Ductless mini-split heat pumps for casitas, garages and additions

Gas Furnace Service and Safety

If your home runs gas heat, the annual check matters for more than comfort. We inspect the heat exchanger for cracks, verify flame characteristics and gas pressure, test the flue draft, check safety switches, and confirm carbon monoxide levels are where they belong.

Furnaces here sit idle for eight months, then get asked to run overnight. Dust burn-off smells, failing igniters and clogged flame sensors are the classic first-cold-night calls.

Choosing Between Heat Pump, Furnace and Dual-Fuel

All-electric homes almost always land on a heat pump. Homes with existing gas service and higher heating demand may do better with a dual-fuel system that switches to gas below a set outdoor temperature. Utility rate plans matter here too, and we'll walk through how your plan changes the math before recommending anything.
