Maintenance Tips for Ductless Heating Systems


The biggest benefit of a ductless heating system is the incredible efficiency it offers. But if it’s in poor repair, the efficiency will start to suffer and decline. What a waste it would be to have such a great system and not have it operating efficiently! In order to keep your ductless system running smoothly, it will need regular maintenance.

Why is ductless heating maintenance necessary? When does it need to be done? What maintenance can you do yourself? We’ll tell you all about it.

What Ductless Maintenance Involves

When you get heat pump service in Spokane, WA, your technician will be specially qualified to work on systems like yours. They’ll know exactly what to look for, and they’ll be able to maintain your heat pump and ductless system in a streamlined and knowledgeable way.

The basic parts of the maintenance routine are as follows.

  • Cleaning: All parts of the system will be cleaned. This reduces wear and tear during system operation, and it also makes it so your technician can easily see all components and what condition they’re in.
  • Inspecting: With everything clean and visible, your technician will check on all the parts of the system, including running tests such as making sure the motor is drawing the correct amperage of power and the thermostat is correctly calibrated.
  • Lubricating: When a system has moving parts, friction is created, and excess friction causes the system to work harder to keep the parts moving. Your technician will lubricate these parts so they glide smoothly. 

Benefits of Ductless Maintenance

Regular heat pump maintenance, as you can see, cuts down on friction and wear and tear. This helps the system to run efficiently and effectively. It also reduces the likelihood that repairs will be needed and even lengthens the potential lifespan of the system.

It also provides an opportunity for minor problems to be caught early. Your technician can get things back on track and prevent serious malfunctions from occurring.

Frequency of Ductless Maintenance

You would have your AC system or your furnace maintained once a year. Your heat pump should be maintained twice a year because it is providing both those services, doing twice the job that either of those other systems do.

Maintenance to Do Yourself

This in-depth maintenance we’ve been discussing must be done by a trained, qualified professional. But there are a few things you can do to help your heat pump function as well and as efficiently as possible.

  • Air Filters: Each air handler has an air filter, usually reusable, which should be removed, washed, dried, and put back each month.
  • Condenser Unit: The condenser or outdoor unit also needs to be kept clean so it has the air circulation it requires. Trim away plants, rake up debris, and wash any mud, dirt, or dust off the unit with a hose—gently, not with a high-pressure nozzle.
  • Keep a Watchful Eye: If something doesn’t seem right with your ductless system—a noise, a smell, dripping moisture, poor performance—don’t ignore it. Have a technician take a look as promptly as possible so a small issue won’t worsen.
