St. Louis Park’s postwar neighborhoods, including areas like Texa-Tonka, are filled with modest homes built in the 1940s and 50s, many of which have added ductless mini splits over the years to cool additions and finished basements. The city’s proximity to Minnehaha Creek also brings extra humidity to certain pockets of town. O’Boys Plumbing, Heating & Air has served St. Louis Park homeowners for more than 25 years.

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!

Signs Your Mini Split Needs a Repair Visit

Established homes throughout St. Louis Park often show similar signs when a mini split starts having trouble. Here’s what to look for.

Unit not responding to controls

Catching these early helps avoid a bigger repair down the road.

How We Handle Repairs Across St. Louis Park

We start each visit by reviewing your system’s age and original installation, since many St. Louis Park homes have relied on the same mini split for years without a full inspection. Our technicians check refrigerant levels, electrical connections, and drainage as standard steps.

Once we’ve identified the issue, we complete the repair and test the system under full load to confirm proper performance. For homes closer to Minnehaha Creek, we also pay close attention to condensate drainage, since humidity can build up more in those pockets of the city.

We finish by walking through our findings and offering maintenance guidance suited to your home.

The combination of older housing stock and creek proximity leads to a fairly consistent set of issues throughout St. Louis Park.

Condensate drainage clogs

Inside a Typical Service Visit

A homeowner named Paul in the Texa-Tonka neighborhood called us after his mini split started leaving water stains on the wall below the indoor unit. Our technician found the condensate line had cracked, likely from age, which is common in units that have run for many years without maintenance.

After replacing the line and testing the drainage, the leak stopped completely. Paul asked how to prevent this going forward, so our technician recommended a yearly inspection to catch wear like this before it causes damage.
