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 It's Time to Call for Repair

With so many lakes and wetlands scattered through Eagan, moisture related wear is a common trigger for mini split problems. Look out for these signs.

Water leaking from the indoor unit
Musty odor when running
Reduced cooling or heating output
Rattling or grinding noise
Frequent cycling on and off
Higher than usual energy bills

The sooner these are addressed, the less likely they are to turn into a bigger repair.

What to Expect During a Repair Visit

Our technicians begin by reviewing your system’s age and location, since homes closer to Eagan’s lakes and wetlands often see more moisture exposure than those on higher, drier ground. We check drainage, refrigerant levels, and electrical connections as standard steps in every visit.

Once we’ve identified the cause, we complete the repair and test the system under normal operating conditions. For homes near water, we pay particular attention to condensate lines and outdoor unit corrosion.

We finish by reviewing what we found and offering maintenance tips suited to your home’s specific setting within Eagan.

Inside a Typical Service Visit

A homeowner named Kevin near the Blackhawk area called us when his mini split started giving off a musty smell every time it ran. Our technician found mold growth inside the unit caused by a slow condensate leak, likely worsened by the home’s proximity to the lake.

After clearing the drain line and cleaning the affected components, the smell disappeared and the system ran normally again. Kevin asked what he could do going forward, so our technician recommended a seasonal check given how close his home sits to the water.

frequently asked questions

Does living near a lake affect my mini split?

It can. Homes closer to lakes and wetlands often see more moisture exposure, which can lead to drainage issues or mold if not addressed.

Why does my unit smell musty when it runs?

This is usually caused by mold or mildew buildup from a slow condensate leak. A technician can clean the unit and repair the drainage issue.

Can mold inside a mini split be cleaned instead of replacing the unit?

In most cases, yes. Cleaning the affected components and fixing the underlying drainage issue usually resolves the problem.

How quickly can I get a technician out for a repair?

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

What can I do to prevent moisture related issues?

Routine maintenance, including drain line checks, helps prevent the moisture related issues common in homes near water.
