With spring weather approaching, it’s time to complete your home’s annual HVAC maintenance plan. Heat pumps are no exception. They must be properly maintained to reach maximum heat pump efficiency. Well-maintained heat pumps are 10 to 25 percent more efficient than those that aren’t regularly maintained.
What You Can Do
The most important maintenance task you can perform is to change the air filter, a simple task you can do yourself. A dirty filter slows down airflow, dragging down performance and possibly damaging the compressor. As such, it’s important to change your filter monthly.
Coils and fans also need to be cleaned and maintained. Just turn off your unit, and clean your fan and outdoor coils with a coil cleaning solution. Then, remove any vegetation around the outdoor unit. Lastly, make sure to clean your home’s return and supply registers.
What Your HVAC Service Expert Will Do
Some heat pump maintenance tasks must be performed by an HVAC service expert. Here’s a quick checklist:
- Inspect ducts for leaks and obstructions, and repair if needed.
- Clean the blower.
- Measure refrigerant charge, topping off if necessary.
- Measure airflow.
- Check electric terminals, and tighten connections if loose.
- Touch up non-conductive coating.
- Lubricate moving parts.
- Inspect, tighten or replace fan belts.
- Test controls (heating and cooling).
- Test thermostats for correct performance.
Before your technician arrives, you may want to make a note of any questions or concerns you have about heat pump performance or noises. Here are some things that may be concerning you:
- Duct noises: If you hear noises when ducts expand and contract, you might consider putting a dent in the side of the duct to make the surface rigid.
- Rattles: Inspect for loose parts if you feel competent to do so, and then tighten.
- Squeaks: Fan belts may need replacing.
- Grinding: Motor bearings may be worn out, which require a professional fix.
With proper maintenance, your heat pump should last at least 10 years and maybe as many as 30. To learn more about heat pump efficiency, contact Team Bob’s Heating Cooling Plumbing. We serve Grand Traverse County and the surrounding area.
