Spring Heat Pump Maintenance Checklist

Help your Mitsubishi Electric mini splits keep you cool this summer.

Schedule a tune-up this spring with Kearney HVAC.


Spring is here, and as the weather continues to warm, homeowners from Quincy, MA to Portsmouth, NH are getting ready to turn their heat pumps from heating to cooling mode, so they can continue to take advantage of the energy savings and high efficiency of heat pump technology.

But just like any heating and cooling system (even the ones that lower your utility bills and deliver home comfort all year long!), your Mitsubishi Electric heat pumps will benefit you most when you schedule regular preventative maintenance and tune-ups. Here are a few of the things both you and an experienced heat pump service technician will want to check before air conditioning season begins this year.

1. Keep Your Outdoor Unit Clean and Clear

The outdoor portion of your Mitsubishi Electric ductless mini split heat pump is called the condenser, and it needs to be kept free and clear of debris and dirt to operate properly. One easy thing homeowners can do is to make sure that leaves, fallen branches, and high grasses or plants don’t cover or obstruct their outdoor unit.

2. Change Your Air Filters

Changing your air filters shouldn’t just be a once a year occurrence. Air filters help keep your indoor air quality high, removing pollutants and unhealthy particles from the air in your home and making it safe and healthy for your family. For best results, filters should be cleaned or replaced at least every one to three months of use. Dirty air filters can decrease efficiency and lead to breakdowns, not to mention poor indoor air.

3. Check Your Condensate Drain

Like air conditioners, heat pumps also act as dehumidifiers, removing humidity from the air. The excess moisture from your mini split collects into a drain pan and eventually runs down a condensate line that was drilled through the exterior of your home when your Mitsubishi Electric mini split was installed. However, if your condensate line becomes clogged or blocked up, it could lead to water damage or ice buildup on your mini split’s coils that can cause serious issues.

It’s easy to check to see if any water is dripping out of your condensate line (a good sign it’s working!), but harder to actually diagnose the underlying problem and fix it. That’s just one of the reasons why a professional heat pump spring maintenance call is so beneficial for your home.
