The Proper Cleaning of Heat Pumps to Remove Mold
Should I clean my heat pump myself or call a professional?
Heat Pumps, or ‘Mini-Split’ Ductless systems are a great way to heat your home in colder months, and cool it in hot months. However, due to the way they operate, they draw in elements from nature and if not maintained properly can suffer from becoming contaminated with mold.
Dangers of Mold
Mold can cause nasal and throat issues, cold and flu-like symptoms, and exasperate breathing issues and allergens. Some mold exposure can cause more serious health problems, including chronic lung infections such as legionnaires disease

Moisture, Mold and Your Heat Pump System
Heat Pumps work by exchanging heat and distributing air. They are prone to condensing water, which is where mould loves to grow. Moist air and parts of the system that are damp for long periods can be prone to mold infestations. If left for too long, the mold will manifest itself on the blades, the coil, fan and other components. It can also spread throughout the system to other area’s of your house.
Periodic Maintenance & Cleaning
Most manufacturers recommend cleaning your mini-split system every 1 – 2 years. We highly recommend getting a certified, insured professional cleaner as if not done properly it can damage your machine and your home electrics. The Heat Pump runs on electricity so extreme care must be taken when cleaning. Use the following steps as a guideline:
*** ALWAYS SHUT THE ELECTRICITY OFF AT BREAKER PANEL or on exterior condenser unit. If you are unsure, contact a professional, insured cleaner now
*** BE SURE NOT TO GET MOISTURE ON ELECTRICAL COMPONENTS ***
1. Shut off power by breaker panel (usually two circuits) or on outside condenser unit.
2. Wear safety mask, gloves and goggles
3. Remove filters and the cover (usually a few screws, covered by pull-out tabs) and any accessories
4. Cover electrical and any exposed circuits with tape/cling-wrap. Check there is no power to machine by using current tester.
5. Cover wall, lay drop sheet on any area you do not wish to get wet
6. Spray coils, blades and parts with an antibacterial, non-acidic cleaner (leave for 10 – 15 minutes) a mild soap & water can work
7. Rinse with power washer (set to low so as to not damage the coil blades! (less than 1500 psi)
(if you don’t have suitable power washer, brush solution off and rinse with sponge)
8. Use a flashlight to inspect the blower wheel (look through the bottom vent to spinning fan cylinder) If it has mold or dirt build up, rinse with washer/sprayer, or remove & clean (see You Tube vids on Blower Wheel removal)
9. Let dry, replace covers and accessories
10. Pressure wash outside condenser unit with chemicals and rinse (or use hose)
