What problems come up with heat pumps after the first year or two?
Refrigerant leaks and dirty coils are the big ones.
After a couple of years, the most common issues are slow refrigerant leaks, a clogged outdoor coil, and a failing reversing valve. Check your filter monthly and get a yearly
Checked Sep 9
Why?
Leaks are the top culprit Refrigerant lines vibrate and can develop pinhole leaks, dropping efficiency and eventually freezing the coil.
Dirt kills airflow A dirty outdoor coil or filter makes the system work harder, raising bills and shortening compressor life.
Reversing valve wears The part that switches between heat and cool can stick, leaving you stuck in one mode.
Installation quality matters a lot; a bad install can cause issues sooner, but that's not a typical first-year problem.
Who is this call about heat pump problems right for?
Right for
- Homeowners with a heat pump older than 18 months
- People who skipped the first-year maintenance
- Anyone noticing higher electric bills in winter
- Owners in dusty or pollen-heavy climates
Wrong for
- Renters with a landlord-managed system
- People who just installed a unit under warranty
- Those with a heat pump less than a year old
- Owners who already do monthly filter changes and yearly tune-ups
What does heat pump maintenance cost in 2026?
| Figure | Value | Why it matters |
|---|---|---|
| Yearly maintenance visit | $150 to $300, 2026 | Catches small leaks and dirty coils before they freeze the system. |
| Refrigerant leak repair | $200 to $1,500, 2026 | Fixing a pinhole leak early avoids a full recharge and compressor damage. |
| Reversing valve replacement | $800 to $2,000, 2026 | A stuck valve leaves you without heat or cool, so fix it fast. |
| Filter replacement | $10 to $30 each, 2026 | Monthly swaps keep airflow up and prevent coil freezing. |
What's the biggest heat pump mistake after year one?
The biggest mistake is ignoring a slow refrigerant leak because the system still runs. It keeps cooling or heating, but efficiency drops and the compressor runs hotter, which can kill it in a season. Instead, if your electric bill jumps 20% or more with no other change, call a tech to check pressures and look for oil stains on the lines.
How do you decide if your heat pump needs attention?
- Check your air filter this week and replace it if it's dirty.
- Look at the outdoor coil for leaves, grass, or dust buildup and rinse it with a garden hose.
- Compare your last two winter electric bills for a jump over 20% with no usage change.
- If you see ice on the coil in winter or the system blows lukewarm air, book a service call now.

What does a refrigerant leak cost to fix?
Usually $200 to $1,500, depending on the leak. A small fix like a valve or fitting runs a few hundred; a coil replacement can push past a grand. The refrigerant itself is the cheap part.
How often should I get a tune-up?
Every 1 to 2 years for a heat pump. That's the standard for a tune-up, and given the leaks and dirty coils you asked about, yearly is the safer call.
