Heat pumps are a great alternative to traditional HVAC systems thanks to their optimal energy efficiency ratings. However, even with their many modern comfort and cost advantages, they’re still at risk of developing problems. These are a few of the most common issues you may face with your heat pump.

Is Your Heat Pump Constantly Running?

It’s normal for a heat pump to run longer when temperatures reach extreme highs or lows. When your system constantly runs on a day with a moderate temperature, there’s a good chance that something’s going wrong.

First, check your thermostat to ensure your settings haven’t accidentally changed. Then, make sure your air filter isn’t clogged. A full filter restricts airflow and forces the system to work harder to meet your comfort settings.

Your system could also be due for professional maintenance. These tune-ups include cleaning away excessive grime and tightening any loose connections, which can help minimize wear and tear. Annual maintenance appointments are the best way to prevent the need for repairs and protect your system’s lifespan.

Are Your Air Handlers Not Working?

An air handler is your heat pump’s indoor component, responsible for distributing your system’s heated or cooled air. If you notice one or more handlers not working, check your circuit breaker to see if it has tripped.

Additionally, older handlers can struggle with bad wiring. Fraying or loose wires may leave the equipment working inconsistently or less effectively. Another common reason behind a compromised handler is a failing or blown motor.

Have You Noticed a Lack of Heating or Cooling?

If your thermostat settings are correct and your system still doesn’t heat or cool your home enough, the problem could be a lack of refrigerant. Without enough of this chemical, the system won’t be able to transfer enough heat to or from outside the house.

A heat pump that can only heat may have a faulty reversing valve. This valve is responsible for switching your HVAC system between its heating and cooling functions. Since this is a specialized part, only a professional can service it.

Other common causes of faulty operation include dirty coils or something blocking the outdoor unit. In addition to helpful troubleshooting, an experienced technician will also be able to let you know if your system is the correct size for your home, as incorrect sizing can cause problems.

Are There Changes in Your HVAC Cycles?

An average heat pump cycle should run for about 10 to 15 minutes a couple of times per hour. This rate can fluctuate depending on the season and the temperature you set. Short cycling, though, occurs when your HVAC system frequently turns on and off.

Your system may short cycle if it’s overheating or leaking refrigerant. There may be an issue with your thermostat or with the size of your heat pump. Make sure that your air filters are clean, and if the short cycling continues, contact an HVAC professional for help.

Is Your System Emitting Odd Noises or Smells?

Heat pumps can push out musty or stale air when struggling with biological growth within the system. A common sign of an overheating system is an odor of burning rubber or plastic. A rotten egg or sewage smell often means an animal has gotten inside the heat pump and died.

Your heat pump should be relatively quiet, but loose parts within the system can excessively rattle or vibrate. A malfunctioning system may create a loud thumping noise reminiscent of an unbalanced washing machine. Don’t forget to listen for new clicking, squealing, or rattling noises.

Heat pump issues are always best left to trained professionals who can guarantee high-quality results. HVAC experts possess the education, training, and skills to quickly find and resolve a range of heating and cooling concerns.
