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.

How to Know Your Mini Split Needs Repair

Bonus rooms and porches throughout Maple Grove tend to show similar signs when a mini split starts having trouble. Here’s what to watch for.

Room won’t hold a steady temperature
Loud clicking when starting up
Ice forming on the outdoor unit
Weak airflow from the vents
Higher than expected energy bills
System runs constantly without cooling

Catching these signs early keeps your extra living space comfortable through every season.

Our Approach to Every Repair Visit

We begin by reviewing how your system was originally installed, since many Maple Grove homes added mini splits specifically for porches and bonus rooms during construction or shortly after. Our technicians check refrigerant levels, electrical connections, and airflow to determine the actual cause of the problem.

Once identified, we complete the repair and test the system under real conditions to confirm it’s heating and cooling properly. We also check whether the unit was sized correctly for the space, since undersized systems are a common source of ongoing issues in additions.

We finish by explaining what we found and sharing tips to keep your system running well.

Inside a Typical Service Visit

A homeowner named Chris near the Arbor Lakes area called us after his three season porch mini split started running nonstop without ever cooling the space down. Our technician found the unit was undersized for the porch’s glass exposure and square footage, and a slightly low refrigerant charge was adding to the problem.

After recharging the system, Chris and our technician discussed whether a larger unit might serve the space better long term. For now, the repair brought the porch back to a comfortable temperature for the rest of the season.

frequently asked questions

Can a mini split be undersized for a three season porch?

Yes. Porches with a lot of glass exposure need more cooling or heating capacity, and an undersized unit may run constantly without keeping up.

Why does my bonus room mini split run nonstop?

This is often caused by low refrigerant, a dirty filter, or a unit that isn’t sized correctly for the space.

Do newer Maple Grove homes still need mini split repairs?

Yes. Even newer systems can develop issues over time, especially in spaces that see heavy use throughout the year.

How quickly can I get a repair scheduled in Maple Grove?

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

Should I repair or replace an undersized unit?

A technician can evaluate your space and system to help you decide which option makes the most sense long term.
