# Heat Pump Repair in Annandale, VA

Heat pump repair and installation in Annandale, Virginia. 24/7 dispatch, same-day service.

## Why heat pumps fail in Annandale

Annandale has some of the oldest housing stock in Fairfax County — much of it 1950s and 1960s, with additions and conversions layered on over decades. We regularly find systems that were sized for the original footprint and never updated after a basement conversion or an addition, which is why they run constantly and fail early.

Annandale has a lot of older homes that were converted from oil or baseboard heat to heat pumps without a proper load calculation. Those systems are usually undersized for the actual envelope, and they show it every January when the auxiliary heat never turns off.

## FAQ

Q: My house was converted from oil heat. Why does the heat pump not keep up?
A: Conversions often reuse the original sizing assumptions, which were based on a different system. Without a load calculation the heat pump ends up undersized for the actual envelope. That is fixable.

Q: How much does heat pump repair cost in Annandale?
A: Diagnostic is $89, waived on approval. Most repairs run $250 to $900. Major component replacements — reversing valve, compressor — run higher.

Q: Do you work on older homes with limited space?
A: Yes. Annandale has tight mechanical closets and low crawlspaces. We check clearances before recommending equipment so the install actually fits.

Q: Should I repair or replace a twenty-year-old heat pump?
A: Past twenty years with a refrigerant leak or failed compressor, replacement usually wins. Under that, repair is usually the better call.

Q: Do you charge extra for nights and weekends?
A: After-hours dispatch is $149, covering the trip and diagnosis. Repair pricing is the same as daytime.

Q: How fast can you get here?
A: Same day for most requests before 4pm. No-heat calls dispatched within two hours.
