Heat pumps are a game-changer for efficient home heating and cooling, providing year-round comfort while reducing energy costs. But, like any HVAC system, they need proper care and operation to perform their best.

At Airtek, we know how essential it is to keep heat pumps running smoothly—and avoiding some common mistakes will help you get the most from your investment.

In this guide, we’ll highlight 8 things you shouldn’t do to your heat pump if you want it to function efficiently for years to come.

1. Don’t Set Extreme Temperatures

It’s tempting to crank the thermostat way up in winter or way down in summer to heat or cool your home faster, but heat pumps don’t work that way. Extreme settings force the system to work harder, increasing wear and energy consumption without speeding up temperature changes. Stick to a moderate range for efficiency—around 68°F in winter and 78°F in summer.

2. Don’t Skip Regular Maintenance

A heat pump is only as good as the care it receives. Failing to schedule annual tune-ups and inspections can result in reduced efficiency, poor airflow, and expensive repairs. Regular maintenance ensures your system stays in peak condition and identifies potential issues early. Contact Airtek’s network of HVAC professionals to find a certified technician near you.

3. Don’t Obstruct Airflow

Your heat pump relies on free airflow to function properly. Blocking indoor or outdoor units with furniture, plants, or clutter forces the system to overwork. Make sure the outdoor condenser has at least two feet of clearance on all sides and keep indoor vents clear for optimal performance.

4. Don’t Rely on Backup Heat Too Much

Many heat pumps come with backup electric resistance heating for extremely cold days. While it’s useful in emergencies, over-relying on it increases your energy bill. Trust your heat pump to do its job efficiently—even in cold weather. For added peace of mind, Airtek carries supplemental heating solutions tailored to your needs.

5. Don’t Ignore Unusual Noises 

A heat pump typically operates quietly. If you notice strange sounds like rattling, grinding, or whistling, it’s a sign that something could be wrong. Ignoring these noises can lead to costly breakdowns. Call a licensed technician immediately if your system is making abnormal sounds.

6. Don’t Wait to Clean Filters

Dirty air filters can cause airflow problems, reduced efficiency, and increased wear on your system. Be sure to check and clean filters every 1-2 months, especially during periods of heavy use. Need replacement filters? Shop our high-quality inventory at Airtek.

7. Don’t Turn Off Your Heat Pump in Extreme Weather

Many homeowners mistakenly believe that turning off their heat pump during very hot or cold days will save energy. In reality, this makes the system work harder when it’s turned back on. Instead, let your heat pump maintain a stable temperature throughout the day.

8. Don’t Forget to Use the Right Mode

Using the wrong settings can limit your heat pump’s efficiency. Ensure you’re using “Heat” mode in winter and “Cool” mode in summer. Many units also have an “Auto” mode, but for precise control, it’s better to switch manually depending on the season.

Conclusion: Your heat pump is an investment in year-round comfort and energy efficiency. But to get the most out of it, you need to know what not to do. Avoid these eight common mistakes, and your heat pump will reward you with consistent performance, lower energy bills, and fewer repairs.
