"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!"

"Fred is very personable and friendly. He returned my call right away, even though I placed it after hours. He replaced one old toilet with a new one he just happened to have in his truck, and it works great even though it's a low flow one. Prices are very reasonable. Fred is my plumber from now on."

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."

"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)."

"I won't know until next week how it went so hopefully it will still be 5 stars. They will start on installation soon. So far they have been very responsive and professional. Thanks, Janice"

"Great -- the plumber arrived within an hour or two of my husband calling and was able to locate the leak and repair it. He also found and repaired an additional issue that we did not even know we had (an attachment to our hot water heater that regulates water pressure needed replacement)."
