Is your furnace blowing cold air, not turning on, or making banging and rattling noises? Covington Heat & Air provides fast, dependable heater and furnace repair across Oklahoma City and the surrounding metro — with same-day availability and emergency response. Locally owned, licensed, and trusted by OKC homeowners for over 19 years.
Oklahoma winters can turn severe fast. A hard freeze that rolls in overnight can push a marginal heating system past its limit, and when your furnace or heat pump stops working in January, it’s not just uncomfortable — it can be a safety issue for your family.
At Covington Heat & Air, we’ve been diagnosing and repairing heating systems across the OKC metro for over 19 years. We work on gas furnaces, heat pumps, dual fuel systems, and ductless mini-splits for both residential and commercial customers. Whether your system is short-cycling, blowing cold air, won’t ignite, or making sounds it shouldn’t, our licensed technicians will find the problem and fix it right — usually in a single visit.
We serve Oklahoma City, Edmond, Moore, Norman, Mustang, Yukon, Piedmont, Midwest City, Del City, Bethany, Warr Acres, Nichols Hills, and Guthrie. Call us at (405) 568-9463 for same-day heater repair in OKC, or use our contact form to schedule. Want to get ahead of a breakdown?

If your system is running but your home isn’t warming up, or if it’s blowing cool or room-temperature air, something is wrong. The most common causes are a dirty or failing flame sensor, a cracked heat exchanger, a failing inducer motor, or a gas valve issue. A furnace blowing cold air can also mean the system overheated and the high-limit switch tripped as a safety measure. Our technicians will run a full diagnostic, tell you exactly what they found, and give you an upfront price before any repair is made. We also have a detailed guide on why furnaces blow cold air if you want to understand what might be happening before you call.
If your energy bills have jumped noticeably without a change in how you’re using your system, your furnace is working harder than it should. This usually points to a dirty air filter starving the system of airflow, a failing heat exchanger operating at reduced efficiency, a thermostat that’s miscalibrated, or an aging system that’s simply losing its efficiency rating year over year. An annual fall tune-up catches most of these issues before they show up on your utility bill. Our [heat tune-up is $89](#acmaintenance) and covers flame sensor cleaning, amp checks on the blower motor, gas pressure verification, and more.
Before you call, check the basics: make sure the thermostat is set to HEAT and the temperature is set above the current room temp, check the breaker panel for a tripped circuit, and verify the furnace power switch (the wall switch near the unit that looks like a light switch) is in the ON position — these get bumped off accidentally more often than you’d think. If all of that checks out and the system still won’t fire up, the issue is likely a failed ignitor, a faulty control board, a pressure switch failure, or a safety lockout triggered by a prior fault. Call us and we’ll diagnose it same day.
A properly maintained furnace runs quietly. Unusual sounds are your system’s way of telling you something needs attention — and the longer you wait, the worse it typically gets. Banging or booming when the furnace starts usually indicates delayed ignition from a dirty burner. Squealing points to a worn blower belt or failing motor bearing. Rattling can mean a loose panel or failing inducer assembly. A burning smell at startup is sometimes just dust burning off seasonal buildup, but a persistent burning or metallic smell warrants an immediate call — it can indicate an electrical issue or a cracked heat exchanger, which is a carbon monoxide risk. Don’t ignore it. Call us at (405) 568-9463.
Not all heating systems are the same, and knowing what type you have matters when something goes wrong. At Covington Heat & Air, our technicians are trained on all major heating system types and brands. Whether you have a standard gas furnace, a heat pump, a dual fuel system, or a ductless mini-split, we install, repair, and service them all across the OKC metro. If you’re not sure what system you have or what would work best for your home, give us a call — we’ll walk you through it.
One of the most common questions we get is whether a repair is worth it or if it’s time to replace the system entirely. There’s no universal answer — it depends on the age of your equipment, the cost of the repair, and how efficiently your current system is running.
As a general rule, if your furnace is over 15 years old and the repair cost exceeds $1,000, replacement is often the smarter long-term investment. Newer high-efficiency gas furnaces can operate at 95%+ AFUE ratings compared to 70-80% on older equipment, which translates to real savings on your monthly gas bill. A new system also comes with a manufacturer’s warranty and typically requires far fewer repairs in the first decade.
That said, a furnace that’s 8 years old with a $300 repair is almost always worth fixing. We’ll give you an honest assessment on site — we have no interest in pushing a replacement when a repair makes sense. If replacement is the right call, we’ll walk you through your options and what a new system would cost, and financing is available if needed.

When your heat stops working in an Oklahoma winter, waiting isn’t an option. We take emergency heating calls seriously and do our best to get a technician to you the same day.

The most common warning signs we see: the system blowing lukewarm or cold air when set to heat, the furnace short-cycling (starting and stopping repeatedly without completing a heating cycle), unusual noises at startup or during operation — especially banging, squealing, or rattling — higher than normal gas or electric bills, the pilot light or flame appearing yellow or orange instead of blue, and visible soot or corrosion around the furnace. Any of these warrant a call. Some are quick, inexpensive fixes; others need immediate attention. Our technicians can usually walk you through what they’re seeing within minutes of arriving.
A high-efficiency gas furnace (95%+ AFUE) extracts nearly all of the heat value from the fuel it burns, compared to older systems that lose 20-30% of that energy up the flue. In practical terms, that translates to noticeably lower gas bills every month through winter, more consistent heat distribution throughout your home, and quieter operation. Modern systems also have variable-speed blower motors that maintain more even temperatures and reduce the hot/cold cycling that older single-stage systems are known for. Combined with available utility rebates and financing options, the payback period on a new high-efficiency system is often shorter than homeowners expect.
Yes — we work on all major heating system types including gas furnaces, heat pumps, dual fuel systems, and ductless mini-splits. Heat pumps are increasingly common in the OKC area and require a technician who understands both the heating and cooling sides of how they operate. If you have a heat pump that’s not heating efficiently — especially in temperatures below 35°F when the auxiliary heat should be engaging — that’s a specific diagnostic issue we see often and know how to address quickly.
