My heat pump isn’t heating at my Granbury lake property — what’s wrong?

Most common causes: a reversing valve stuck in cooling mode, a defrost board issue locking the system out of heating, or low refrigerant. Lake environment corrosion can also affect the defrost sensor. We diagnose in both modes before recommending anything.

Can a heat pump handle a Hood County winter?

Yes. Modern heat pumps work effectively down to 20–25°F, which covers the vast majority of Hood County winter events. Below that, backup heat strips engage. If yours isn’t keeping up in cold weather, something is wrong. Call us.

Do you offer a Free Second Opinion on heat pump quotes in Granbury?

Yes. If another company quoted you a heat pump replacement, call us before you sign. We’ll give you an honest second look at no charge.

Is it worth repairing or replacing my heat pump?

Under 10 years old with a component failure — almost always repair. Over 15 years with a compressor failure — replacement often wins on 5-year economics. We run honest numbers both ways.

How fast can you get to Granbury for a heat pump emergency?

About 40 minutes from our Weatherford base. Emergency response available 24/7. Call 817-341-5142.

Why Granbury Heat Pump Problems Are Different

Lake Environment Corrosion

Lake Granbury humidity can speed up heat pump corrosion near the water, affecting coils, electrical contacts, and capacitors. Lakeside systems need these conditions checked during diagnostics to prevent missed issues and recurring failures.

Dual-Mode Complexity

Heat pumps run in both heating and cooling modes, making components like reversing valves, defrost boards, and refrigerant systems harder to diagnose. We understand heat pump behavior and identify the real issue correctly the first time.

Defrost Issues in Hood County Winters

Hood County freeze events can force heat pumps into repeated defrost cycles. When a defrost board or sensor fails, the system may stop heating on the coldest nights — a common Granbury heat pump issue.

COMMON REPAIRS WE HANDLE DAILY:

Reversing valve failure (won’t switch modes)

Refrigerant leaks (correct charge critical for heat pumps)

Defrost board and sensor failures

Coil corrosion  (lake environment)

Capacitor and compressor issues

Most are same-day fixes. Our trucks carry heat pump-specific parts.

The Granbury Heat Pump Reality

A lake property heat pump running all night but not heating usually points to a stuck reversing valve, defrost issue, or refrigerant problem. These are often repairable. We run a full diagnostic before recommending replacement.
