Tuckers Air Conditioning, Heating & Plumbing Hvac

“An older client recently needed an urgent repair under some complicated circumstances. She had no heat during the coldest days of the year thus far. After getting estimates from two other companies that were wildly different and didn't seem to make sense or be fully trustworthy, Ken Tucker made a visit. He took the time to properly evaluate the situation, submitted an estimate that made sense and showed that he fully understood the requirements involved. Further, he was respectful and kind during his visit to a vulnerable adult, and he worked to get client's heat restored asap. As the client had limited resources, they also showed themselves to be compassionate and charitable. Tuckers Air Conditioning, Heating & Plumbing showed themselves to be 100% trustworthy, professional, resourceful, reasonable and very caring in their approach. I truly don't know what we would have done without them. Highly recommend!“

BPM Heating & Cooling Hvac

“Date of service: May 2024

I have waited awhile to do this review because I needed to see if there is a remarkable difference with our electricity consumption with the new HVAC system.

Feb. 28.2025
Fast forward to 9 months after.

We are very happy and satisfied with the service and product we got from BPM. Our new HVAC system is not only energy efficient but it also kept our home cool in over 100・ weather in the summer and very comfortable in -8・ weather this winter and saved us about 40% of our old electric and oil expenses combined for many years.

This was one of the best major decisions we have ever made for house upgrade. The only regret we have was not doing it sooner. A huge thank you to Rich K. for making everything very easy and a pleasant experience; from the free estimate, to consultations with suggestions on best options, to several inspections prior to install and of course most importantly providing financing for the project.

We highly recommend this company for quality product and workmanship. Rich and his crew were very professional during install and even left our basement clean as if they were not even there.“

N E Bob Waltz Plumbing & Heating Inc Hvac

“I had a great experience with Waltz Plumbing. I needed a water heater replaced and originally called another company who wanted $50 just to come to my house for an estimate. When I called Waltz they had me take a picture of the old water heater and they were able to give me an exact quote over the phone for a replacement. They came out the very next day and installed my water heater. The old one was so old they had to leave it in my basement for a few days to drain because it was falling apart and they couldn't remove it until it was empty. Some sludge drained out and clogged my drain. They came out immediately and snaked the drain to fix the blockage. They said that was part of the warranty and was covered by my original payment. Super friendly plumbers AND excellent service/workmanship. I'm a customer for life now!“
