Thompson Plumbing came to install new air and heating units today. The technicians worked efficiently for 7 hours without a break, completing the installation and clean up, as well as answering any questions we had. We were very pleased with their work and courtesy. Great job!

Thompson plumbing was excellent from the initial phone call to the technician who arrived EARLY the same day to the bill! I will call them again if/when needed!

The guys were great! Polite, friendly and quick. They came to check one thing and I asked them to fix a couple more items and they had no complaints and seemed genuinely happy to take care of all my electrical concerns.

Doug J.

I had a sudden drop in water pressure, and I got same day service. The repairman was great and searched less obvious places and found and fixed the issue. Awesome service!

Another great job by Thompson Plumbing, Heating, Cooling and Electrical! The techs are consistently friendly, professional, and efficient no matter what service they provide.

Our kitchen sink would never completely drain so I called and made an appointment. I got an appointment the next day to have the issue diagnosed. The problem was diagnosed quickly and resolved quickly as well. Very impressed with the whole process and would recommend to anyone to use them. Also, very reasonably priced!
