Troubleshooting doesn’t have to feel like decoding alien signals.
In this blog, I’ll help you recognize the most common hiccups, explain what’s probably going on inside your unit, and give you straightforward steps to tackle the issue. Whether you plan to DIY or want to speak your tech’s language, my goal is to empower you with clear, practical knowledge so you can keep your heat pump humming happily for years to come. Ready to jump in? Let’s troubleshoot like pros! 🧠⚡
1️⃣ Problem: Poor Heating or Cooling Performance
What’s Going On?
If your heat pump isn’t heating or cooling like it used to, your system might have a dirty air filter, a refrigerant leak, a blocked coil, or a thermostat issue.
🔍 How to Fix It
-
Check the thermostat is set to the correct mode and temperature — it happens to the best of us.
-
Replace dirty filters; clogged filters restrict airflow and make your system work too hard.
-
Inspect the outdoor unit for debris and clean the coils carefully — follow these coil cleaning tips from ENERGY STAR.
-
Call a pro if refrigerant levels seem low — R-32 requires a certified tech to check and recharge.
2️⃣ Problem: Ice Buildup on the Outdoor Coil
What’s Going On?
Icing can occur in cold weather or if the system can’t defrost properly. Low refrigerant or blocked airflow can make icing worse.
🔍 How to Fix It
-
Make sure snow, grass, and debris are cleared around the unit.
-
Check for blocked drain lines or clogged filters.
-
Observe the defrost cycle — most heat pumps defrost every 30-90 minutes automatically. If yours doesn’t, it could be a control board or sensor issue and may require a pro inspection.
-
The U.S. Department of Energy’s heat pump guide is an awesome resource for understanding defrost cycles.
3️⃣ Problem: Strange Noises (Buzzing, Rattling, Hissing)
What’s Going On?
Heat pumps can make all kinds of noises — some are normal, some signal a deeper issue. Buzzing could mean loose electrical connections, rattling might be loose hardware, and hissing could point to a refrigerant leak.
🔍 How to Fix It
-
Tighten any accessible screws and panels.
-
Inspect the fan blades for obstructions or damage.
-
If you hear hissing, switch the system off and call a pro. Refrigerant leaks require proper R-32 handling, which is best left to a certified technician.

4️⃣ Problem: Weak Airflow
What’s Going On?
Weak airflow could mean blocked ductwork, a clogged air filter, or a slow fan.
🔍 How to Fix It
-
Replace your air filter — one of the simplest and most cost-effective steps.
-
Make sure all vents are open and furniture isn’t blocking return or supply registers.
-
Inspect your ducts for leaks or obstructions.
-
Consider upgrading to a variable-speed fan motor for better performance; read this overview of fan options from the AHRI to help you decide.
5️⃣ Problem: Frequent Cycling or Unit Won’t Turn Off
What’s Going On?
Short cycling — when your unit turns on and off too often — usually points to an oversized unit, refrigerant problems, or a malfunctioning thermostat.
🔍 How to Fix It
-
Verify the thermostat’s temperature settings and placement.
-
Check refrigerant levels — too high or too low can cause rapid cycling.
-
Clean the condenser and evaporator coils so heat exchange is efficient.
-
If it persists, call a pro to evaluate your system sizing and check for control board malfunctions.
6️⃣ Problem: High Energy Bills
What’s Going On?
If you notice a spike in your utility bills without any change in weather or usage habits, your heat pump might be losing efficiency.
🔍 How to Fix It
-
Schedule a professional maintenance visit — a pro can catch issues like refrigerant leaks and worn components before they worsen.
-
Check your home’s insulation — leaky windows and doors can make any heat pump work overtime.
-
Consider upgrading to a smart thermostat; these ENERGY STAR–certified options help optimize runtime and can pay for themselves quickly.
7️⃣ Problem: Refrigerant Leaks
What’s Going On?
Leaks can happen due to loose flare fittings, pinholes in copper lines, or worn-out valves.
🔍 How to Fix It
-
Look for oil stains around refrigerant lines and fittings — a classic sign of a leak.
-
Have a certified pro repair leaks and evacuate the system before recharging with R-32.
-
Leaks can reduce system efficiency and increase emissions, so don’t wait — the EPA refrigerant safety overview explains why quick repair is so important.
