Heating services cover the repair, replacement, installation, and seasonal maintenance of the equipment that heats a home, which in this region means gas furnaces, electric furnaces, and heat pumps. We at Rapid Heat and Air are a licensed and insured mechanical contractor in Durant, Oklahoma, serving Bryan County and the North Texas communities across the Red River. One company handles the entire life cycle of the system, so the technician maintaining a furnace in October works from the same records as the installer.

What We Do for Heating Equipment
Rapid Heat and Air performs four kinds of heating work, and most homeowners need all four over a system’s life.
Heating Repair
Heating repair restores a system that has stopped working or stopped working well. Our technicians measure before replacing anything: voltage at the control board, gas pressure or heat strip amperage, temperature rise across the heat exchanger, and static pressure in the ducts. That sequence identifies which component actually failed rather than which failed as a consequence.
See our heating repair service in Durant for the full details on diagnostics and common faults.
Heating Installation and Replacement
A heating installation replaces equipment that has reached the end of its service life or was never correctly sized for the home. Sizing is the step skipped most often. A load calculation determines the heating capacity a house needs from its square footage, insulation, window area, orientation, and air leakage, rather than from the size of the unit being removed.
See our heater installation service for what a replacement involves.
Heating Maintenance
Heating maintenance is a scheduled inspection and service visit performed before the heating season rather than during a failure. On a gas furnace, it covers the burners, flame sensor, heat exchanger, venting, blower, and filter. A heat pump covers the refrigerant charge, defrost control, reversing valve, and auxiliary heat strips.
See our heater maintenance service for the full checklist.
Emergency Heating Service
A total heat loss during a cold snap is treated as a scheduling priority. Bryan County carries a 99 percent winter design temperature of 20 degrees, the outdoor temperature local heating equipment is sized to handle, and a house losing its heat source at that temperature cools faster than most homeowners expect.
Why Sizing Decides How Well a System Performs
Equipment sizing is set by a load calculation, not by the capacity of the old unit. According to the Air Conditioning Contractors of America, a proper load calculation performed in accordance with the Manual J 8th Edition procedure is required by national building codes and most state and local jurisdictions. Manual J covers single-family detached homes, small multi-unit structures, condominiums, townhouses, and manufactured homes.
Oversizing is the more common error, and it costs comfort rather than saving it. An oversized furnace satisfies the thermostat quickly, shuts off, and starts again shortly after, the short-cycling pattern that drives most component wear. An oversized heat pump behaves the same way and also struggles to dehumidify in the shoulder seasons, which matters in a climate where humidity stays high into autumn. Undersized equipment runs continuously on design days and leans on auxiliary heat strips, the most expensive way to heat a house.
What We Service
We work on gas furnaces, electric furnaces, heat pumps, including dual fuel configurations, packaged units, and the duct systems and controls that serve them. We service equipment we did not install. Where a system is still under manufacturer warranty, we check that coverage before quoting a replacement part, since a warrantied component leaves the homeowner paying labor only.
Licensing and Code
Mechanical work in Oklahoma requires a license issued by the Oklahoma Construction Industries Board, and Rapid Heat and Air is licensed and insured in both Oklahoma and Texas. Residential mechanical and fuel gas work in Oklahoma is governed by the 2018 International Residential Code, adopted as the statewide minimum by the Oklahoma Uniform Building Code Commission. Combustion venting, gas piping, and equipment clearances all fall under it. Permits and inspections are set by the City of Durant and Bryan County rather than the state, because the Board licenses the worker but does not permit the work.
Refrigerant work on heat pumps also requires EPA Section 608 certification, a federal requirement that applies to any technician who opens a sealed refrigerant circuit.
Why Homeowners Here Choose Us
Rapid Heat and Air is a Durant-based contractor, not a regional operation dispatching from three hours away.
- We size equipment before we quote it. A replacement quote that does not reference a load calculation is a guess about the most expensive purchase in the system
- We diagnose before we quote a repair. The failed part and the cause of the failure are frequently different components
- We work on both sides of the Red River. Coverage runs across Bryan County and into Grayson County, Texas, under licenses held in both states
- We back our work with a warranty. Terms depend on the equipment and scope, and we state them before the job starts
- We service what we did not install. A system installed by another contractor is still a system we will maintain
A Full System Replacement Before a Cold Snap
An aging heat and air system failed just ahead of the coldest stretch of winter, and both units needed replacing rather than repairing. The job was quoted, completed, and cleaned up with no added costs.
“My “vintage” heat and air system went out just before our coldest spell and needed a full replacement of both units. Rapid Heat and Air came through when others didn’t.”
Tumey
Replacing both units together matters, because a new condenser paired with an old evaporator coil rarely delivers its rated efficiency. Read this review on Google.

Heating is one half of what most homes in this market need. We also handle air conditioning services and ventilation services, which matters with a heat pump, because the same outdoor unit and the same duct system carry both the heating and the cooling load.

Frequently Asked Questions
How often should a heating system be serviced?
Once a year, before the heating season begins. An annual visit catches the failures that develop quietly: a flame sensor accumulating residue, a cracking inducer motor bearing, a filter restricting airflow enough to trip the high limit. For a heat pump, which runs year-round in both heating and cooling, most manufacturers recommend service twice a year. Scheduling in the shoulder season means shorter waits than calling during the first hard freeze.
How long does a heating system last?
A gas furnace commonly lasts fifteen to twenty years and a heat pump commonly lasts ten to fifteen, though both depend heavily on maintenance, sizing, and run hours. A heat pump has a shorter expected life than a furnace because it operates in both seasons and accumulates roughly twice the run time. Equipment installed at the wrong capacity wears faster regardless of brand. A technician can estimate remaining life from the model year, the component condition, and the service history.
Should I replace a furnace with a heat pump?
It depends on the fuel prices, the home’s insulation, and how the existing ductwork performs, so the answer varies by house rather than by preference. A heat pump provides both heating and cooling from one system and runs on electricity alone. A gas furnace delivers higher supply air temperatures and does not depend on outdoor conditions. In an Inland South climate, the winters are mild enough that heat pumps perform well, and dual fuel systems pair a heat pump with a gas furnace that takes over below a set balance point.
Do you service commercial heating systems?
Rapid Heat and Air holds mechanical licenses in Oklahoma and Texas and works on both residential and light commercial heating equipment. Commercial work differs in equipment type, access, and scheduling, and larger rooftop or multi-unit systems should be discussed before a visit is scheduled so the right technician and parts are dispatched. Describe the equipment and the building when you contact us and we will confirm whether it is within our scope.
What areas do you cover for heating service?
Rapid Heat and Air serves Durant and the surrounding Bryan County communities, including Calera, Colbert, Caddo, Bokchito, Achille, Bennington, Mead, and Blue, plus Sherman, Denison, and Pottsboro in Grayson County, Texas. Coverage in Texas is held under a separate Texas mechanical license. A system outside that footprint may still be serviceable depending on the equipment and the schedule, so it is worth asking.
