Furnace Repair in St. George, UT

No heat, or a furnace acting up? Fast, honest furnace repair across Southern Utah.

Intro

A cold house has a way of making everything else feel harder.

Cox Climate Control handles furnace repair for homeowners across St. George and Southern Utah. Gas furnaces, propane systems, heat pumps, and inverter systems. We work on all of it.

You get a fast response, a real diagnosis, and the price before any work starts. If the fix is small, we say so. We never turn a cold night into a sales pitch.

How We Diagnose the Problem

Guessing is expensive. So we do not guess.

Every furnace repair starts with a full diagnostic. We check the ignition, the burners and gas pressure, the safety controls, the airflow, and the thermostat. When the situation calls for it, we inspect the heat exchanger with a camera and check for gas leaks.

We keep going until we find the real cause, not just the part that quit last.

Then you get a plain-English explanation and the exact price, before we touch anything. You approve it, then we work. No surprise fees, ever.

When a Furnace Problem Is a Safety Issue

The calm, factual version: a gas furnace with a cracked heat exchanger or a gas leak can put carbon monoxide into your home. You cannot see it, and you usually cannot smell it. So here is the safety line, plain and simple. If you smell gas or a carbon monoxide alarm goes off, leave the house first. Call the gas company or 911 from outside. Then call us. For everything short of that, call us directly. We check for gas leaks and heat exchanger damage as part of the job, so you get heat that is safe, not just warm.

Should You Repair or Replace Your Furnace?

Our honest take, the same one we give in your living room.

Most furnace problems are worth repairing. A failed ignitor, a control issue, or a worn part is usually a straightforward fix on a system with life left in it.
Replacement enters the conversation when the furnace is old and the repairs start stacking. The blower motor and control board wear over the years, and pouring money into a tired unit stops making sense at some point. That is also why, when we replace an AC system, we recommend replacing the furnace with it.

Either way, you get a straight answer with real numbers. And if someone else already quoted you a furnace replacement, get a free second quote from us first. One customer did exactly that and got same-day service with zero pushiness.

Fast Help When the Heat Goes Out

Southern Utah cold snaps sneak up on people. The furnace sits quiet for months, then one cold front asks it to perform, and the hidden problem shows itself at the worst time. Do not wait it out in a cold house. We offer same-day service, Saturday hours, and Sunday emergency calls. Our trucks come stocked, so most repairs finish on the first visit. Next fall, beat the cold front entirely with a furnace tune-up.

Great experience. Honest and will definitely use them again and refer them to everyone. Willing to do the repair rather than try and sell us a whole new unit.

I had an excellent experience with Cox Climate Control! Ethan was professional, knowledgeable, and quickly diagnosed a serious issue with my air conditioner that had been causing me a lot of trouble. He fixed it much faster than I expected, and everything has been working perfectly ever since. I truly appreciate the honest service, fast response, and high-quality work. I highly recommend Cox Climate Control to anyone looking for reliable HVAC service. Thank you, Ethan!

Ethan came out in an Emergency call at Night when our a/c quit workingThe temperature was 109. He examined the a/c and found 1 condenser finished and compressor broken. He said he had 2 portable a/c units he could bring so we would not have to move my ill husband and I to a hotel. He came back with the units and set them up. to cool down our house. This was completed after 12 midnight. He said he would check on us the next day. This all happened on a Saturday night. Ethan said they could come back on Monday to discuss a new a/c at our request. He did return with a quote that we thought was fair and we organized to install the next day Tuesday. If you are looking to replace your A/C you could not find a more competent, caring, reliable Company. We highly recommend Cox Climate Control.

We recently had to replace our entire AC system and after lots of research, we chose Cox. We are so glad we did! Devin was patient as we explored many different options, drafted a few quotes for us, and answered all of our many questions. The team that came out to do the install was great as well! We felt very confident using Cox for such a big project.

Our AC unit randomly stopped working on a Sunday. It was July, during monsoons and things were pretty dire. (The chocolate chips in my pantry even melted!) Devin with Cox Climate Control answered the call and we had cool air that evening! He showed up, gave a great quote and didn’t pressure us to upgrade our unit. I cannot recommend them enough!

Cox Climate went above and beyond to take care of us in the middle of July! Tough to get service when you need it most. I was impressed about their competitive pricing and quick response! It’s refreshing to see companies that still value customers and taking care of the ‘little guy.’

Cox Climate Control is the ONLY way to go!!!! My AC went out in the middle of the night, so I called first thing in the morning. They had a technician at my house that afternoon, and my AC was repaired the same day. From the very first phone call to the final invoice, their communication was outstanding. They kept me informed every step of the way, were professional, friendly, and made the whole process stress-free. On top of that, their pricing was very reasonable. It’s hard to find companies that provide this level of customer service these days, and I wouldn’t hesitate to recommend Cox Climate Control to anyone needing HVAC service.

Furnace Repair FAQs

Common causes include an ignition problem, a thermostat or control issue, low gas pressure, or an airflow restriction. A proper diagnostic finds which one, so you only pay to fix the real problem.
It could be as simple as a tripped breaker or thermostat setting, or a failed ignitor or control board. Check the breaker first, then call us and we will run it down.
Our diagnostic fee is $75 during regular hours and $125 after hours and weekends. From there, every repair is priced fairly and approved by you in writing before work begins.
Turn it off and call us if you notice a gas smell, and leave the house and call the gas company or 911 first if the smell is strong or a CO alarm sounds. For other symptoms, shutting the system off until we arrive protects it from further damage.
Most problems are worth repairing on a furnace with life left. When repairs stack up on an aging unit with a worn blower motor or control board, replacement becomes the smarter spend. We give you a straight answer with real numbers.
Usually, yes. We work 7AM to 5PM every day including Saturday, take Sunday emergency calls, and stock our trucks so most furnaces are fixed on the first visit.
