Plymouth is home to more than a dozen lakes, including Medicine Lake and Parkers Lake, and its neighborhoods span everything from 1960s homes to brand new construction. That range means ductless mini splits throughout the city face very different demands depending on a home’s age and how close it sits to the water. O’Boys Plumbing, Heating & Air has repaired mini splits across Plymouth for more than 25 years.

Why Homeowners in Plymouth, MN Trust Us

Excellent service from the call to the technician! Rare. They were able to come out same day in the evening! Even more rare. Chad was knowledgeable, explained everything to me and I couldn't be happier with the final bill! Unheard of!! I will refer everyone to O'Boys.

We had a great experience with O’Boys. We had a furnace tune-up done, and Chad was really knowledgeable and informative. He walked us through options and pricing, and helped us understand what to expect with our furnace in the coming years. We look forward to working with O’Boys again.

I had Great experience with Rob during the consultation. He was detailed, informative, personable and professional. He gave me options and broke down rebates and payment options for me. Reasonable price as well!

Second time using O’Boys and they did not disappoint! Chad was so knowledgeable, efficient, and kind. Was able to fix my problem and gave me some great tips going forward. Excellent work and excellent customer service. Chad—you rock—thank you so much!!

Gavin from O'Boys Plumbing came to deliver & fill our water softener. He was very polite, efficient and professional. He did a great job.

Signs Your Mini Split Needs a Repair

With homes of so many different ages scattered across Plymouth, mini split issues can show up in a variety of ways. These are the signs our technicians see most.

Inconsistent room temperatures
Excess condensation on the unit
Grinding or squealing noises
Weak or no airflow
Higher than expected energy bills
Visible corrosion on components

If your system shows any of these, scheduling a repair sooner rather than later can prevent a bigger breakdown.

How Our Technicians Approach Every Repair

We start by reviewing the age and setup of your system, since Plymouth’s mix of decades old homes and newer builds near the lakes means installations vary quite a bit across the city. Our technicians check refrigerant levels, wiring, and drainage before making a diagnosis.

Once we’ve identified the issue, we complete the repair and test the unit under full load to confirm it’s performing correctly. For homes closer to Medicine Lake or Parkers Lake, we pay extra attention to condensate drainage, since humidity tends to run higher near the water.

We finish every visit by explaining what we found and offering guidance suited to your home’s age and location.

Problems We Frequently Repair Across Plymouth

Given the range of home ages and lake proximity across the city, a handful of issues come up often.

Condensate drainage clogs
Aging electrical components
Refrigerant leaks
Dirty evaporator coils
Failing capacitors
Improperly sized units

Our technicians take the time to identify the actual cause rather than just addressing the symptoms.

Inside a Typical Service Visit

A homeowner named Eric near the Parkers Lake area called us when his mini split started shutting off every few minutes instead of running a full cycle. Our technician found a failing capacitor, a common issue in units that have been running for several years without maintenance.

After replacing the part and testing the system through a full cycle, the unit ran smoothly again without cutting out. Eric asked what he could do to avoid future breakdowns, so our technician suggested a yearly checkup to catch aging components before they fail.
