"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"I contacted Fred by email first, as on his website, it says you can either call or email. But there was no response to my email for a couple of days, so I decided to call. Fred asked me to text him my address. He made an appointment to come to the house a couple of days later. He came on time, drilled a hole through the concrete block in the basement and installed a new faucet. He added a bleeder valve to the copper pipe and explained how I should bleed the pipe after turning off the inside valve before the cold winter months. Fred was pleasant and informative. He did a good job. It took about an hour and 15 minutes. To contact Fred, you might want to send him an email explaining the work needed, and include your phone number so he can call you back. Or send him a text that includes your address."

"Kan and Puia arrived the same day as my call and completed an evaluation of services needed, in my case mostly a replacement hot water heater. They came back the next morning, put down drop cloths, did the work and made a suggestion for something that needed attention that we hadn't noticed. Very pleasant people to work with. Work was completed in good time with great attention to detail at a good price. It's good to have Kan in my contacts. I will definitely call him in the future. Thanks, Kan!"

"Fritz B. was my sales rep and he clearly knew what he was doing, including making a few minor recommendations that were in my financial interest. Easy to set up the scope of work. The grew was great, came in and did a great job, took about 6 hours. They even rerouted the exhaust flue for my hot water heater even though they did not replace the heater because the install guy Chris said "they did this dumb". Overall a great experience and I would recommend."

"We needed a water heater replacement due to a leak in our existing unit. The company came out promptly after our phone call, provided an estimate, and came back first thing the next morning with a new water heater to install. The owner and staff were patient in answering any questions that we had and did an amazing job cleaning up after they were finished with installation. They went above and beyond to ensure that we were very satisfied with their service. They never made us feel as if they were rushing to complete the job. We would highly recommend them!"
