Furnace repair for Tucson homes
No heat isn't just uncomfortable. We treat it like the safety call it can be.
Same-day furnace repair when the schedule allows, a gas and carbon monoxide safety check on every visit, and workmanship we guarantee in writing.
Desert nights get cold too
Tucson's reputation is heat, but once the sun drops the desert gives that heat right back. A furnace that only runs a handful of months a year doesn't get the wear-and-tear warning signs a system running daily would - it just works, until one night it doesn't.
A gas furnace problem isn't only a comfort problem. Our maintenance checklist includes a gas leak inspection and a carbon monoxide sample on every heating visit, because we'd rather catch a safety issue during a routine call than have you find out about it the hard way. That same standard applies when you call us for a repair.
Signs your furnace needs a repair call
- Furnace won't turn on, or won't stay lit
- Weak, cold, or uneven airflow from the vents
- Clicking, banging, or squealing when it starts up
- A gas smell near the furnace or vents
- Short cycling - turning on and off before the house actually warms up
- A gas or electric bill that's climbing with no other explanation
Furnace symptoms, decoded
The most common no-heat calls we see in Tucson, what's usually behind them, and how we confirm it before quoting anything.
| What you're seeing | What it usually means | How we check it | Typical fix |
|---|---|---|---|
| Furnace runs but blows cold air | Failed hot-surface ignitor or a dirty flame sensor | Ignition sequence observed end to end, ignitor tested | Hot-surface ignitor about $360; a dirty flame sensor is usually a cleaning |
| Won't start at all | Thermostat, a tripped safety switch, or a control problem | Control circuit traced, every safety checked — not just reset | Quoted flat once the failed part is confirmed |
| Starts, then shuts off within minutes | Overheating from starved airflow, or a failing limit switch | Temperature rise measured against the nameplate, filter and limit switch tested | Often an airflow fix; the part is quoted in writing if the limit switch is done |
| Burning smell on the first cold night | Usually normal dust burn-off — occasionally wiring or a motor overheating | Visual inspection and motor amp draw before we call it normal | Dust burn-off clears within the hour; anything electrical gets fixed before the furnace runs again |
| Blower runs nonstop | Fan relay or control board | Control outputs tested at the board | Quoted after diagnosis; a worn-out blower motor itself runs about $725 |
Our process
How we handle a no-heat call
01
We ask the right questions first
What's it doing, when did it start, and what have you already tried - a few minutes on the phone can save you a wasted trip.
02
We test, not guess
A technician checks connections, gas pressure, ignition, and airflow with the same instruments we use on installation jobs, so the diagnosis matches what's actually wrong.
03
We check gas and carbon monoxide safety
Every furnace repair includes a gas leak inspection, because a heating problem can be a safety problem before it's a comfort problem.
04
You get the repair, priced before we start
You approve the fix and the price before any work happens. No surprise invoice at the end.
