"Jimmy Gusky HVAC is truly as good as it gets. One of our AC units went down and through the warranty company found our way to Jimmy Gusky himself. Although out of their territory, Jimmy was willing to make the extra trip to diagnose the problem. He was very responsive to get our initial service call scheduled and determined the unit needed to be replaced, and we all know these units usually decide to break down only when pushed to the limit in the hottest summer months and we need AC the most. He did the legwork to get the warranty company to honor the recommendation and as you can see from the attached photo put in a much more substantial unit that is doing a fabulous job cooling the home. Add to that he actually had the unit and scheduled the install even before the warranty company approved the swap out. I that isn't one of the greatest examples of outstanding customer service and going above and beyond to exceed expectations, I don't know what is. Big thanks to Jimmy and team for their commitment to excellence!"

"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!"

"They have recently included electricians to their company."

"Rema was fantastic. It was a tricky job replacing a water heater tank in a cramped space, and Rema both helped guide us to the right approach plus handled the install and removal of the old unit flawlessly. We'll hire Remedy again for future projects!"

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"Tried to push me into purchasing a new water heater and quoted me higher price based on estimate from their affiliated company (which had accidentally quoted me wrong price initially)."

"Called the main number and the lady I spoke with was very pleasant and easy to work with. Was looking to have a 50 gallon hot water heater installed, 2 drains snaked and a new faucet installed. She booked my appt for the next day. Zam came to the house to provide us the quote and even offered to do half the job then and come back in a few days to do the hot water heater. He was incredibly professional and did a great job on all the work. I highly recommend them and will call them again."

"Jamie our plumber arrived right on time & very efficiently performed three jobs for us. These included replacing a kitchen disposal, installing a vanity water faucet, flushing the water heater. He patiently explained each task and stayed until all were completed. We were so pleased we've entered into a service contract with Beacon Home Services."
