Minneapolis is full of century old bungalows and craftsman homes, many of which have added ductless mini splits to cool third floor conversions, additions, and rooms that older knob and tube wiring never supported well. Around the Chain of Lakes, homes also deal with extra humidity for much of the year. O’Boys Plumbing, Heating & Air has repaired mini splits throughout Minneapolis for more than 25 years, with certified technicians experienced in the city’s older housing.

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!!

Warning Signs Worth a Repair Call

Historic Minneapolis homes tend to show similar warning signs when a mini split starts to struggle. Here’s what to look out for.

Room stays warm or cold despite running
Flickering lights when the unit starts
Water leaking near the indoor head
Loud rattling or buzzing
Rising energy costs
Unit won’t power on at all

Older electrical systems especially benefit from catching these signs before they turn into a bigger issue.

How We Repair Systems in Minneapolis Homes

We begin every visit by reviewing your home’s electrical setup and the mini split’s original installation, since many Minneapolis homes have wiring that predates the unit itself. Our technicians check refrigerant levels, connections, and airflow to isolate the real cause of the issue.

Once identified, we complete the repair and test the system under full load to confirm it’s heating and cooling properly. For homes near the Chain of Lakes, we also check condensate drainage closely, since humidity levels can run higher in those neighborhoods.

We wrap up by explaining our findings and offering guidance suited to your home’s age and wiring.

Inside a Typical Service Visit

A homeowner named James in the Linden Hills neighborhood called us after noticing his mini split flickered the lights every time it turned on. Our technician found the unit was drawing more power than the circuit was designed for, a common issue in older Minneapolis homes with outdated wiring.

After making the necessary electrical repair and testing the system, the flickering stopped and the unit ran normally. James mentioned he’d been putting off looking into it, so our technician also explained a few signs to watch for that might point to bigger electrical concerns in an older home.

frequently asked questions

Do older Minneapolis homes need special mini split care?

Sometimes. Older wiring and installation methods can differ from modern standards, so our technicians account for that during every repair.

Why do my lights flicker when the mini split turns on?

This is often caused by the unit drawing more power than the circuit was designed for, which a technician can diagnose and correct.

Can a third floor conversion mini split be repaired the same way?

Yes. The repair process is the same, though our technicians pay extra attention to how the unit was originally installed in converted spaces.

How quickly can I get a repair scheduled in Minneapolis?

We offer same-day service for most repair calls throughout the city.

Does humidity near the lakes affect my system?

It can. Homes near the Chain of Lakes may see higher humidity, which can affect condensate drainage if not maintained.
