Mustang’s heating picture is shaped by one fact: most of its homes are young. The town has grown fast to the south and west, along SW 59th, SW 74th, SW 89th and State Highway 152, and that means a lot of systems installed at the same time by builders, now aging together.
Mustang housing: newer, faster-built, and mostly attic systems
Compared with Edmond or Northwest OKC, Mustang has relatively few homes from before the 1980s. A small established core near Mustang Rd and the older parts of town has closet and garage gas furnaces. But the majority of homes, especially in the newer subdivisions south and west of town, were built from the late 1990s on, and that construction shows up in the equipment:
- Heat pumps are common. Many newer homes were built all-electric or with a heat pump as the primary heat source.
- Dual-fuel is common too. A heat pump outdoors paired with a gas furnace in the attic.
- Attic placement is standard. Air handlers and furnaces sit in the attic, with flex duct runs to each room.
- Builder-grade equipment. Systems chosen to meet code at the lowest installed cost, typically single-stage with basic controls.
None of that is bad, but it creates a predictable set of problems as those systems age.
The 10–15 year wall
The biggest pattern we see in Mustang is builder-grade systems hitting 10 to 15 years at the same time across entire neighborhoods. Heat pumps run in both summer and winter, so they accumulate wear faster than a gas furnace that only runs a few months a year.
What fails at that age:
- Capacitors and contactors on the outdoor heat pump, often first noticed on a cold morning
- Blower motors in the attic air handler or furnace
- Defrost controls and sensors, leading to heat pumps that ice over and stop heating
- Reversing valves, which can leave a heat pump stuck in cooling mode
- Inducer motors and pressure switches on the gas furnace side of dual-fuel systems
A single repair on a 12-year-old system usually makes sense. When the third or fourth major repair shows up on the same unit, or the heat pump needs a compressor, we will show you the repair price next to a replacement option and let you choose.
Heat pumps and dual-fuel: what Mustang homeowners should know
If your home is all-electric with a heat pump, the main thing to watch is auxiliary heat. On cold nights, the system adds electric resistance heat to help the heat pump. That is normal in short bursts. If it runs constantly, OG&E bills climb fast, and something is usually wrong, such as low refrigerant, a defrost failure or a thermostat misconfigured for the system. Our explainer on what emergency heat on your thermostat means helps sort out the two settings.
If you have dual-fuel, the thermostat decides when to switch from the heat pump to the gas furnace. A switchover point set too low makes the heat pump struggle; set too high and you burn more gas than needed. We check and adjust that setting on every dual-fuel visit.

Attic furnace issues in newer Mustang homes
High-efficiency gas furnaces in Mustang attics usually vent through two PVC pipes and produce condensate that drains through a small line. Those details cause many winter calls:
- Clogged condensate lines trip a safety switch and the furnace shuts off, sometimes with water in the drain pan or on the ceiling
- Frozen condensate drains during hard freezes, especially where lines run through cold attic space
- Blocked or iced PVC vents that trigger pressure switch faults
If you see water near your attic unit or a stain on the ceiling below it, read why is my furnace leaking water. For the vent pipes, see why does my furnace have two PVC pipes.
Mustang winters: wind, freezes and the first cold snap
Mustang sits in Canadian County on the open southwest side of the metro. Winter fronts arrive with strong winds that pull heat out of homes and attics, and ice storms can coat outdoor heat pump units and PVC vents. The February 2021 deep freeze was a hard test for the area: heat pumps ran on backup heat for days, and attic condensate lines froze in many newer homes.
The first real cold snap usually comes in late October or November. A furnace tune-up in Mustang before then catches a weak capacitor, dirty flame sensor or partly clogged drain while it is still an easy fix. Our membership plan schedules that visit for you each year.
If you smell gas or your carbon monoxide alarm sounds, get everyone out of the house and call 911 or Oklahoma Natural Gas from outside. Do not reset or relight the furnace.

Frequently asked questions
- Who repairs furnaces and heat pumps in Mustang, OK?
- Graco services gas furnaces, heat pumps and dual-fuel systems throughout Mustang (73064) and the far west OKC edge in 73128. We are veteran-owned, available 24/7, and show flat-rate pricing before work starts. Call (405) 500-5333.
- My Mustang home is only 12 years old. Why is the furnace already failing?
- Many newer Mustang homes were built with builder-grade equipment, and those systems commonly start needing major repairs between 10 and 15 years, especially heat pumps that run year-round. Typical failures at that age include capacitors, blower motors, reversing valves on heat pumps, and inducer motors on gas furnaces. Regular maintenance extends life, but it does not make a basic system last forever.
- What is dual-fuel, and do I have it?
- Dual-fuel pairs an outdoor heat pump with an indoor gas furnace. The heat pump heats on mild days and the furnace takes over when it gets cold enough. If you have an outdoor unit that runs in winter and also two PVC pipes or a gas line going to the indoor unit, you likely have dual-fuel.
- Why is my electric bill so high in winter in Mustang?
- In all-electric heat pump homes, the most common cause is auxiliary or emergency heat running far more than it should, which uses electric resistance heat. A low refrigerant charge, a failed defrost control or a thermostat set up wrong can all trigger it. We check the heat pump and the thermostat settings together.
- Should I replace my builder-grade heat pump with a gas furnace?
- It depends on whether your home has natural gas, how the existing ducts and electrical are set up, and how you weigh comfort against operating cost. Many Mustang homes are good candidates for dual-fuel, which keeps the heat pump for mild weather and adds gas for hard freezes. We lay out the options with pricing before you decide.
