A Legacy Of Happy Customers

"I have been very pleased with the McQuillan Brothers! I just had technician RJ out to fix the boiler. He put in a new ignitor and explained the whole process. He answered all of my questions as well! Great company to work with!"

"I needed emergency service for my sewer that backed up into my house. The technician arrived promptly, and was knowledgeable and efficient. He was respectful of my home and wore paper booties over his shoes. I will definitely use them again."
Selma S.

"My quote appointment was on Monday morning and by Friday night, I had AC. I SO appreciate that the technicians stayed late on a Friday night to finish the installation. They were fast and polite and put everything back where they found it. Thank you McQuillan!"

"McQuillan Brothers always does an awesome job and they don't try to up-sell a product to me. I appreciate that. They replaced both my furnace & AC units this fall. They show up promptly and work efficiently. They are very respectful & friendly."
Reggie B.

"What an awesome company! I highly recommend McQuillan Bros. Our A/C wasn't working during 90 degree temps. I called them after 9pm and they got to my house at 9:48pm. Had all the parts and fixed it within 30 minutes."
St. Paul, MN
"I called with a plumbing issue they got me in the very next day. They called to confirm the appointment and let me know that the technician is on his way. He showed up on time was very helpful and presented us with a few different options. I couldn’t have been happier!"
