Everyone promises heat. We put it in writing.

Tucson is known for its heat, but the furnace still has a job to do. Desert nights drop fast once the sun's down, and a furnace that only runs a few months a year is exactly the kind of system that fails quietly and then fails completely, usually on the coldest night of the stretch.

We repair, replace, and maintain furnaces and heat pumps across the Tucson area. Qualified installations come with our written 1-year money-back guarantee. Every repair is backed by guaranteed workmanship - if something's not right, we make it right, in writing, not just as a sales line.

If you smell gas or a carbon monoxide alarm sounds, leave the house, call 911 or Southwest Gas from outside, and don't flip switches. A CO alarm does not detect a natural-gas leak.

Many Tucson homes heat with heat pumps, not gas furnaces. That distinction matters when describing a problem: burners and flame sensors belong to gas furnaces, not heat pumps. If you're unsure which you have, look for the equipment type on an old service invoice rather than opening the equipment. Tell us what the paperwork says when you call.

Tucson has a long cooling season, March into October. Desert dust and monsoon silt load outdoor coils and filters, so the change to cooler weather is a useful reminder to plan a heating check, even if cooling seemed fine.

Before the appointment, write down what you've noticed: whether every room feels cold, whether airflow has changed, and whether the thermostat calls for heat without the house warming. Have the last service invoice handy if you have one. Ask about the checks appropriate to your equipment; the price goes in writing before work starts.
