Heating & Air Conditioning / HVAC near Pewaukee

“A reliable company always responsive when needed. They installed my furnace, air conditioner, and water heater (in 1994) so regularly perform maintenance. I upgraded (myself) my thermostats to Nest units, and when one wasn’t working properly in cooling mode, they fixed it by adding an extra board to the zone, even though they didn’t supply Nest. They also replaced my water heater after it broke down; six months later, it failed again, and they replaced it free of charge—including the labor cost, which many companies don’t cover. Overall, very satisfied!“

“Our HVAC was original to the house and of course, our furnace failed on one of the coldest weekends of the year. We knew it was beyond repair……
We were able to speak with Blake Seider and he connected us with John (the estimator) and we were able to order a new furnace (and A/C) by Saturday night. They came to install it first thing Monday morning. The entire process was seamless and I could not be happier…..I highly recommend them!“

“I called 3 places. a Wisconsin one and a Kenosha one both said" no,not today we have to order the part so..." mind you it's the coldest day of the year. So Misurelli called and the tech( Nicholas)said give me the numbers and I'll see what I can do...apparently miracles because he found the part got it done. I asked why you can and the other couldn't and he shrugged his shoulders. i think becausehe actually tried...and i was a loyal customer to the one shop...was. So Nicholas made the coldest night safe for a old man,little dog.“

“USA plumbing services used for many re do work from previous plumbers. Manager Steve was prompt, kind, patient with my concerns. Their Master plumber Tom is absolutely the best around. Fixed leaking toilet correctly, an old shower that didn't have hot water, and got our washing machine to also use hot water. All these things were addressed prior by other plumbers. Steve also noticed our hot water heater pipes were not to code and Tom re did those and pipes that fed it and the shower. I can say after 20 years of plumbing repairs i finally found a plumbing company i truly trust. Reasonable prices too! Thank you team!“
