"Joe was wonderful.  In the morning, we woke up to our hot water heater not working.   He was here in an hour and replaced the hot water heater installed in three hours.   Great experience and wonderful guy.

"Patrick and Adam came to my house to fix a leaking tankless electric water heater. They could not fix. I wasn't happy with the performance so Patrick recommended a gas vented water heater. Also installed a utility tub in my laundry room. I didn't even call done rite till maybe 11:00am. They came did all work and where out of here by 5:15. How is that for same day service. Jason came to assist. Cleaned up nice crew. I would highly recommend them."

"The technician, Frank Peterson, was very knowledgeable about my heating system. He got it up and running in short order. There will hopefully be follow up on the needed repairs to keep the system running efficiently."

Customers say: Quick response

"I have a maintenance contract. Today Fabian came out. He was very thorough. He spent two hours at my condo performing all kinds of tests. Before he left he went over things I could do to get better performance from my heater. I appreciate the fact that he did not try to pressure me into picking something. He emailed me (while in the truck) options and also explained different ways to pay for it. He noticed the oxygen in my home. My husband had CHF and COPD so I was specifically interested in the ways I can help his breathing better. I believe in todayâ s environment itâ s difficult for companies to get really good employees. This young man , 20, had a great work ethic and a bright future. Very pleased with the service I have received. Thank you Harris."
