When your ductless mini split stops keeping up with Andover’s hot, humid summers or its bitter cold winters, you need a team that knows how local weather affects these systems. At O’Boys Plumbing, Heating & Air, we’ve spent more than 25 years helping homeowners near Round Lake and Crooked Lake keep their comfort systems running strong. Whether your unit is blowing warm air, leaking, or won’t turn on at all, our certified technicians can get to the root of the problem fast.
Andover’s swings between muggy summer afternoons and subzero winter nights put extra strain on ductless systems, especially in homes with additions, garages, or sunrooms that rely on them for climate control. Here are the signs it’s time to call for repair.
Catching these signs early can save you from a full system breakdown during Minnesota’s harshest weather.
Every repair visit starts with a full inspection of your indoor and outdoor units. Our technicians check refrigerant levels, electrical connections, drainage lines, and airflow to pinpoint exactly what’s wrong. We walk you through what we find before any work begins, so there are no surprises.
Once we know the issue, we get to work with the right parts and tools on hand for most common repairs. We test the system thoroughly after every fix to confirm it’s heating or cooling properly before we consider the job done.
Because Andover homes see such a wide temperature range across the year, we also check for wear caused by seasonal stress, like ice buildup on outdoor units in winter or condensation issues during humid summer stretches near the lakes.
Ductless systems are reliable, but certain problems show up more often in this climate. These are some of the most common issues our technicians repair around Andover.
No matter the cause, we diagnose the real issue instead of just treating the symptoms.
One afternoon, a homeowner named Mark near the Crooked Lake area called us after noticing his ductless mini split in the three season porch had stopped blowing cold air during a stretch of hot, humid days. Our technician arrived that same day and found the outdoor unit’s coils were coated in grime from the lake area’s higher pollen and moisture levels, which was restricting airflow.
After a thorough cleaning and a check of the refrigerant charge, the system was back to cooling the porch evenly within the hour. Mark mentioned he’d been putting off maintenance for a couple of years, so our technician also walked him through a simple upkeep routine to help the unit handle Andover’s humid summers going forward.
Homeowners across Andover trust us because we treat every home like it’s our own. Here’s what makes us different.
When you call O’Boys, you get a team that shows up on time and treats your comfort like it matters.
