Furnace Repair in Las Vegas & Henderson, NV

When your furnace stops working in the middle of a cold desert night, the first question isn't always "how much will this cost?" — it's "is it safe to have this thing running?" We answer that question first, every time.

What's Actually Wrong With Your Furnace

Las Vegas furnaces sit dormant for six or seven months out of the year. That extended off-season creates a specific set of failure patterns that we see repeatedly — and that most homeowners don't expect when the heat finally kicks on in November.

 

The most common furnace problems we diagnose in the Las Vegas and Henderson area:

 

  • Dirty or failed flame sensors — the furnace tries to ignite, then shuts itself off within seconds
  • Ignitor failure from extended summer dormancy — components degrade when they sit unused in extreme heat
  • Blower motor failure — the furnace fires but no warm air moves through the home
  • Cracked heat exchangers — a structural failure that can allow combustion gases to enter living spaces
  • Pilot light or ignition control issues — common in older gas furnace systems

 

Each of these has a different repair path and a different cost profile. We won't know which one you're dealing with until we look — and we'll tell you exactly what we find.

Carbon Monoxide and Heat Exchanger Safety

A cracked heat exchanger is the one furnace problem that goes beyond comfort and into safety. When the heat exchanger fails, combustion byproducts — including carbon monoxide — can mix with the air circulating through your home. It's odorless, invisible, and serious.

 

We don't treat this as a checkbox. Every diagnostic visit includes a safety assessment before we talk about repair options.

What We Check on Every Furnace Diagnostic

Our technicians evaluate the full system before making any recommendations. That includes the heat exchanger for visible cracks or stress fractures, the flame sensor and ignition system, the blower motor and belt, the flue and venting for proper draft, and the overall condition of the unit relative to its age.

 

You'll hear what we found in plain terms — not HVAC jargon — and we'll tell you whether the furnace is safe to operate before anything else is discussed.

If We Find a Safety Concern, You'll Know Immediately

We service and install every major AC brand in Southern Nevada. Your equipment is never a reason we can't help.

Repair First. Replacement Only When It Makes Sense.

Our approach is to repair when repair is the right call. If your furnace is 8 years old and the ignitor failed, that's a straightforward fix. If it's 22 years old with a cracked heat exchanger and a failing blower, the honest answer is that repair dollars are better spent on a new system. We'll tell you which situation you're in — and we won't push replacement to close a larger ticket.

Furnace Repair Is Part of Our Core Service — Not a Seasonal Add-On

Some HVAC companies in Las Vegas treat heating as a winter-only service line. We don't. Furnace repair is part of what we do year-round, which means our technicians stay current on gas furnace diagnostics, ignition systems, and heat exchanger evaluation regardless of the season.

 

We work on all furnace brands — no brand restrictions, no "we only service what we install" policy. If you have a furnace and it's not working, we can look at it.

Furnace Repair — Frequently Asked Questions

  • My furnace turns on but shuts off after a few seconds. What's causing that?

    This is almost always a dirty or failed flame sensor. The sensor detects whether the burner is actually lit — when it's coated with residue, it can't confirm ignition and shuts the system down as a safety measure. Cleaning or replacing the flame sensor is typically a straightforward repair.

  • How do I know if my furnace has a cracked heat exchanger?

    Most homeowners can't detect a cracked heat exchanger without a diagnostic inspection — it's not visible from the outside and produces no obvious smell. Signs that something may be wrong include unusual odors when the heat runs, soot around the furnace, or a carbon monoxide detector alarm. If you have any of these, don't run the furnace and call us.

  • Is furnace repair worth it, or should I just replace the system?

    It depends on the age of the unit, the nature of the failure, and the cost of the repair relative to what a new system would cost. A furnace under 15 years old with a single component failure is usually worth repairing. An older unit with multiple failing parts is a different calculation. We'll give you the honest breakdown during the diagnostic so you can decide.

  • My furnace won't turn on at all in Las Vegas — what should I do first?

    Check your thermostat settings and make sure it's set to heat mode with the temperature above the current room temperature. Check that the filter isn't completely blocked — a severely clogged filter can trigger a safety shutoff. If neither of those resolves it, the issue is likely mechanical or electrical and needs a technician. Call us and we'll get someone out.

  • Do you repair all furnace brands in the Las Vegas area?

    Yes. We service all furnace brands — gas furnaces, forced air systems, and multi-stage units regardless of manufacturer. We don't limit our service to brands we sell or install.
