We’ve been pulling into Warr Acres driveways since 2018. The city is barely a square mile, completely surrounded by Oklahoma City, but it’s got its own building department, its own permit rules, and its own inspector. That matters when you’re replacing a furnace. Out-of-area contractors routinely file OKC permits by mistake, or skip permitting entirely, and homeowners are the ones left holding the bag when a home sale falls through or an insurance claim gets denied. Our Heating & Furnace team knows the difference. We pull Warr Acres permits for every replacement, line up the inspection, and make sure the paperwork is clean before we leave.
The housing stock here is unmistakable: postwar ranch homes built between 1948 and 1975, almost all on slab foundations, with original attic duct systems that are undersized, uninsulated, and collapsing from age. Attic insulation in these homes is frequently still at R-11 or below. That means your furnace is fighting the house itself, not just the weather. We account for that. We measure heat loss properly, size equipment correctly, and fix the ductwork instead of just swapping the box.
Why Fireside Heating & Air Co. Is Warr Acres’s Preferred Heating & Furnace Company
Homeowners in Warr Acres call us back because we treat their homes like we’d treat our own mother’s. Glen Hartman built this company on that principle in 1984, and it’s still how we operate. We’re not the cheapest bid you’ll get, and we don’t try to be. We’re the bid you make once.
Our 90-Day Done Right Promise means exactly what it says: if it’s not right, we make it right, in writing, no paperwork, no arguing. That’s not a slogan. It’s a printed guarantee every Warr Acres customer gets.
A live person answers our phones 24 hours a day, 7 days a week, including holidays. At 2 a.m. when your furnace quits during an ice storm, you’ll talk to someone who can dispatch a technician, not a voicemail tree telling you to call back in the morning.
Our background-checked, uniformed technicians are trained journeymen who put on shoe covers without being asked. They work on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems. Most Warr Acres jobs are completed in a single visit because our trucks are stocked for the specific failures we see in this city’s aging housing stock.
Our Heating & Furnace Services in Warr Acres
Furnace Repair
Warr Acres’s volatile continental climate throws 50°F temperature swings at your system in a single day. That thermal cycling cracks heat exchangers, fries ignitors, and loosens gas valve connections. We see it constantly on NW 50th Street and around the Grove Avenue corridor. A typical furnace repair in Warr Acres runs $135-$630, and we carry common Rheem, York, and Bryant parts on our trucks to finish same-day.

Furnace Replacement
Because Warr Acres is an independent city entirely landlocked within Oklahoma City, every furnace replacement requires a Warr Acres city permit and inspection, not an OKC permit. Our crew routinely finds prior unpermitted installs with undersized breakers, improper bonding, and combustion air violations that OKC inspectors never saw. We handle the permit, coordinate the inspection, and install to code. A full furnace replacement in Warr Acres typically costs $3,150-$6,750, including proper duct modifications these old ranch homes usually need.

Furnace Tune-Up
Our $89 Seasonal Tune-Up is the best money you’ll spend on a Warr Acres furnace. We check gas pressure, clean burners, test safety limits, and inspect heat exchangers for cracks. Given the age of housing here, we often find deteriorating flue pipes and settled attic insulation that’s dropped to near-zero R-value. Catching that before heating season starts prevents mid-winter failures when ice storms are knocking out auxiliary heat across the metro.

Heat Exchanger Inspection & Replacement
Cracked heat exchangers are a carbon monoxide risk we take seriously. In Warr Acres’s 1950s-1970s furnaces, we’ve replaced heat exchangers that have been cycling on and off for forty years. We use combustion analyzers to verify safe operation, and if replacement makes more sense than repair, we’ll tell you straight. No pressure. Just the facts and a written quote.

Gas Valve Repair
Mineral-heavy Oklahoma water and decades of thermal stress seize gas valves in Warr Acres furnaces. We test inlet and outlet pressure, check for proper modulation, and replace faulty valves with OEM-spec components. This is not a homeowner repair. Gas valve work requires proper leak testing and combustion verification. We do both before we leave.

Trusted Brands We Service in Warr Acres
We stock parts and train our technicians on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Warr Acres customers, that means faster repairs without waiting for a parts run to Oklahoma City. We see a lot of Rheem and York systems in the postwar ranches near MacArthur Boulevard, and Bryant equipment in the 1960s builds closer to NW 50th. Our warehouse keeps common ignitors, gas valves, blower motors, and control boards on hand. Most brand-specific repairs are done in one trip.
Common Heating & Furnace Problems We See in Warr Acres Homes
- Unpermitted prior furnace swaps with safety violations. Because Warr Acres has its own building department independent of OKC, technicians doing replacements frequently discover prior installs were never inspected, with undersized breakers, improperly bonded refrigerant lines, and combustion air violations on older gas furnaces.
- Failed defrost boards and frozen condensate drains after ice storms. Warr Acres ice storms freeze outdoor heat pump coils and knock out auxiliary heat strips exactly when they’re needed most. We see this on slab-foundation homes more often than in newer construction.
- Collapsed attic ductwork with near-zero insulation. Original R-11 fiberglass has settled to nothing after seventy years. Heated air leaks into the attic before it reaches the living room, forcing the furnace to overwork and cycling limit switches.
- Corroded evaporator drain pans from hard groundwater. The area’s mineral-heavy water accelerates rust on drain pans and condensate lines faster than in softer-water markets, causing overflow damage and humidity problems.

FAQs - Heating & Furnace in Warr Acres
Yes. Warr Acres is an independent incorporated city with its own building department, and every furnace replacement requires a Warr Acres permit and inspection, not an OKC permit. Out-of-area contractors frequently get this wrong, leaving homeowners with unpermitted work that complicates home sales and insurance claims. We pull the correct permit and coordinate the inspection as part of every replacement. Call (866) 561-3358 if you want us to check whether your current system was properly permitted.
They probably aren’t. Most Warr Acres homes were built with R-11 fiberglass attic insulation that has settled to near-zero R-value after seventy years, and original ductwork was uninsulated or poorly sealed sheet metal. Heated air leaks into the attic before reaching your living space, which is why some rooms never get warm. We measure duct leakage and insulation levels during every tune-up and replacement quote. Call (866) 561-3358 for a free assessment.
Not if you’ve closed off registers to save heat. Oversized garage doors on workshop outbuildings create pressure imbalances when homeowners shut vents, forcing the furnace blower to work against backpressure and tripping limit switches. We see this on acreage properties around Warr Acres. The fix is proper zoning or a dedicated unit, not a bigger standard furnace. We can evaluate your setup and recommend a solution that won’t void your warranty or create safety issues. Call (866) 561-3358 for a free second opinion.
Ice storms freeze outdoor heat pump coils and knock out auxiliary heat strips on dual-fuel systems, forcing the gas furnace to carry the full load during the coldest weather. We see failed defrost boards and frozen condensate drains on Warr Acres slab-foundation homes more often than in newer construction. Annual tune-ups catch deteriorating components before they fail under stress. Our $89 seasonal tune-up includes defrost cycle testing and condensate line inspection. Call (866) 561-3358 to schedule before the next storm.
Warr Acres has hard, mineral-heavy groundwater that accelerates corrosion on evaporator drain pans and condensate lines faster than in softer-water markets. Combined with decades of thermal cycling in these aging systems, rust-through is common. We check drain pan condition during every tune-up and can install corrosion-resistant replacements when needed. Call (866) 561-3358 for an exact quote - estimates are free.
