Not Heating or Not Cooling? We Fix Heat Pumps Year-Round
Not Heating or Not Cooling? We Fix Heat Pumps Year-Round
A heat pump works hard all year — cooling your home in summer and heating it in winter — so when it stops keeping up, you feel it fast. R.A. Dobson has repaired heat pumps across Sterling and Northern Virginia since 1975, and our factory-trained technicians pinpoint the problem, explain it in plain terms, and give you an honest, upfront price before any work begins.
nWhether your heat pump is blowing lukewarm air, running non-stop, or has quit altogether, we will diagnose it and get your comfort back — backed by a one-year service warranty on top of your manufacturer coverage.
Common Heat Pump Problems We Fix
Because a heat pump runs in both seasons, small problems show up sooner than they would on a furnace or AC. Most repairs trace back to a handful of common issues:
What is actually wrong? In plain terms, a few culprits cause most calls. A stuck reversing valve keeps the system from switching between heating and cooling, so it may blow cold when you want heat. A refrigerant leak leaves it too low to move heat and running non-stop. And a defrost fault lets ice build up on the outdoor coil in winter. We test for each and fix the real cause.
Repair or replace? A repair is almost always the smart call for a heat pump under 10 years old and well maintained. If yours is older or needs frequent fixes, we will honestly weigh repair against replacement with you. Ready for a new system? See our heat pump installation page.
A few common questions. How fast can you come out? We offer fast, priority response and put no-heat and no-cooling calls first. Do you service my brand? Yes — all major makes and models, and we are a Carrier Factory Authorized Dealer. Want the full overview? See our heat pumps page.
