"Everything from sales, customer service, installation and the electrical work was great! The split HVAC unit functions perfectly and appears to be the perfect size for the job."

"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!"

"The price was part of my check up I got. I just like that they seemed to want to talk me into having my air conditioning cleaned and it only been out there like 6 months. My interaction with them was fine. I told them no and so be it. The work turned out fine. They were fine."

"They put in a new system. They had to take everything existing out. They showed up when they were supposed to and finished in a week. They were clean and efficient. It was not an easy task. They cleaned up after themselves. Very professional. The owner explained everything to us."
