What Your Neighbors Are Saying About 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.

How to Tell Your Ductless Mini Split Needs Attention

Some problems are easy to spot, while others sneak up on you over time. Here are some signs it’s time to call for ductless mini split repair in Blaine, MN:

Your unit is blowing air that isn’t reaching the set temperature, leaving rooms too warm or too cool.
You’re hearing unusual sounds like grinding, clicking, or rattling coming from the indoor or outdoor unit.
There’s ice forming on the unit, which points to a refrigerant or airflow issue.
You’ve noticed water leaking around the indoor head unit.
The system is short-cycling, meaning it turns on and off more frequently than it should.
Your energy bills have gone up without a clear reason, which can signal that your system is working harder than it needs to.
The unit has a foul or musty smell when running, which may indicate mold or debris buildup inside.

Blaine’s humid summers put extra strain on cooling systems. When moisture levels are high, ductless mini splits have to work overtime to keep indoor air comfortable, and that added stress can bring existing issues to the surface faster.
