The autumn transition to the colder months in the Greater Boston area of MA and Dover, NH is a perfect time to perform annual maintenance on your home’s heating and cooling systems, and ductless Mitsubishi Electric Heating & Air Conditioning systems are no exception.
Mitsubishi Electric heat pumps are efficient units that can make all the difference to the comfort of your home! But they’re far more efficient when maintained by a professional HVAC technician like those at Kearney HVAC.
Curious about what should be on your heat pump maintenance checklist? Here are the top 5 items our technicians focus on during normal annual maintenance for Mitsubishi heat pumps:
1. Replace Your Air Filter and Clean Your Unit
Standing in front of your mini split and getting a whiff of stinky socks despite having cleaned or replaced your filter recently? We recommend scheduling a cleaning ASAP because odors are not a great sign when your mini split handles every breath of air you take in your home.
Poor indoor air quality (or IAQ) is nothing to sneeze at! Having a dirty mini split can cause you and your loved ones anything from aggravated allergy symptoms to potentially hazardous reactions and illnesses caused by mold. An annual cleaning (at a minimum) is one of the most important things you can do to maintain good air quality and a healthy home.
2. Clean Your Coils
According to a report from Southern California Edison, dirty condenser coils can reduce a heat pump unit’s cooling capacity by as much as 40%. For this reason and more, cleaning your evaporator, and your condenser’s indoor and outdoor coils is right near the top of our heat pump repair and maintenance checklist.
Not only does this help keep your Mitsubishi Electric mini splits operating efficiently, it can also reduce your energy bills, maximize the lifespan of your mini split, and help you avoid costly and stressful emergency repairs.
3. Check Your Refrigerant
Did you know that your mini split uses a refrigerant line to bring heat into your home in the winter and move heat out of your home in the summer? The same report from SCE referenced above states that low refrigerant levels can decrease your unit’s cooling capacity by up to 20%.
An annual visit from a Kearney service technician will go a long way in ensuring that your refrigerant lines, coils, and flare connections are in good condition, so you don’t have to worry that you’re missing out on the efficiency you deserve from your mini split.
4. Test Your Compressor
The compressor plays such a vital role in your system’s operation that Kearney HVAC technicians perform a test on your mini split heat pump’s compressor with every maintenance or repair call. Without a well-functioning compressor, your unit will struggle to move the refrigerant between your indoor and outdoor units. This means your Mitsubishi ductless mini split likely won’t be able to keep up with your settings and will leave you with an uncomfortable home.
Our skilled technicians will inspect components like your electronic expansion valves (EEVs) and digital inverter-driven compressors to ensure that they are working as they should while also making repairs to proactively prevent breakdowns.
5. Schedule Next Year’s Maintenance Now
