McQuillan Brothers sets the standard for technical home services , be it electrical, plumbing, heating or A/C. Everything explained in detail with total transparency on the options and costs. We have used lots of folks during our 35 years in St. Paul - these guys are simply the best.

I had a Mini Split Ductless installed in 2020. Mcquillan Bros.did a excellent job. I have it serviced and inspected every year by one of their techs. They always do a excellent job. I highly recommend this company.

A/C system maintenance

Excellent service with upfront pricing. The service was timely and affordable and my sinks are draining again! Zac was skilled, knowledgeable, and friendly. Thank you!

I contacted McQuillan for a spring AC season inspection. They were able to come out the same day, and I was very happy with the service and the price. The tech, Daruis, was professional, friendly, and efficient. because of this interaction, I believe that I will become a home care club member. (I also am to receive a free water heater flush as part of the offering , which was a nice add-on, albeit this will be a different service call.)

Lucas was great! Came to the house, diagnosed the problem, ran tests to verify and fixed in quickly to get us back up and running on the water heater.

Excellent service provided. On time. Very knowledgeable. Great service overall. I would recommend them. Thx

Mcquillan fixed the ignitor. This went well. We were then quoted $3,500 simply to clean our residential boiler system. This 2nd price is not in alignment with national rates for this service and seems predatory to me. It literally took my breath away. I would like to hear the justification for that quoted price from Mcquillans. (In researching this further, Mcquillan’s was purchased by private equity in June of 2024, and may explain the attempted price gauging behavior.)
