Best HVAC Installation Or Replacement in Saint Paul MN

Brian was awesome! Came in and knew immediately what the issue was and fixed our furnace in minutes.! Would highly recommend and ask for Brian!

We have an old home (1905), which we've lived in for 16 years. Recently there was a strange odor coming from the boiler. I called McQuillan Bros. The very old boiler needed to be replaced. The whole crew from start to finish, was very courteous and professional. Both Nick and Mike took the time to patiently explain everything. Nothing felt rushed. I was extremely impressed with how they cleaned up after the job was done. Josh also patiently explained how to set up the new thermostat.

Friendly, fast and professional service.  My tub diverter wasn't working.  They came out within two days and replaced the tub faucet. Their price was lower than other places I checked. The technician was clean and had his own shoe covers.  He explained everything thoroughly and was very friendly.  I would trust him with any plumbing repair.  Thank you!
