“Explained what the problem was and what the options were. Very personable tech.
We have been out of town since before the bad rainstorms earlier this month. Asked them to check on something for us. He found something wasn't working and asked if we wanted him to figure out what was wrong. He tracked down the problem and told us what needed to be done to fix it. He let us know what the additional charge would be and asked him to continue with the additional repair.

Very happy He was able to figure out what the problem was and kept calling to keep us updated.“

“A reliable company always responsive when needed. They installed my furnace, air conditioner, and water heater (in 1994) so regularly perform maintenance. I upgraded (myself) my thermostats to Nest units, and when one wasn’t working properly in cooling mode, they fixed it by adding an extra board to the zone, even though they didn’t supply Nest. They also replaced my water heater after it broke down; six months later, it failed again, and they replaced it free of charge—including the labor cost, which many companies don’t cover. Overall, very satisfied!“

“Cannot say enough about Comfort Air and more specifically Bill Parikka. He was absolutely amazing and not only repaired our AC, but took the time to explain what he did. In addition, he also made some modifications that will help me better maintain the unit. I would use them again without hesitation for any HVAC or heating repairs I would need again. So nice to find an honest and caring contractor. If you ever need a repair or your unit goes down, Bill is the guy to call.Service: HVAC repair“

“I experienced Thielmann & Son's service through my Costco membership. If that does not tell you something, allow me to expand. From the moment of receiving a call from their front desk to the completion of the project, every bit was clock work professional, clean, and honest. Measurements and size of the HVAC system, explanations of what each term means and how it impacts the home, energy consumption, etc were all provided with a lot of patience. I had enough time to do my own research regarding pricing, current labor, comparison of brands and models, etc. I am impressed by these folks and their business model. The work was spot on, clean and surgically executed. I am a loyal customer now for the annual maintenance and if other needs arise. Keep up the good work Thielmann and Sons.“

“We had lost our HVAC system in all the flooding we recently had gotten and I was in need of a new furnace and AC. Called up Weyer & sons and got an amazing quote. They came back at a later date and did the full install and we couldnt be happier. Extremely friendly and fantastic communication. I highly recommend Weyer & sons to anybody who's in need of hvac work. I'll definitely be using them again.“

“Lost power to the furnace and had no heat. Called CGS as they originally installed it back in 1992, as i found out. 30+ year old furnace final winter. He recommended replacement and was able to install the following day. Clark provided us with 4 strong electric space heaters to help keep our family warm enough to make it through the night and installation during the morning. A part failed from the new furnace within less than 24 hours, and he came back promptly and dignosed and replaced it. What are the chances right. Overall, I am very happy with my experience with Clark and others with him at CGS. Older reviews showed him in a negative light, but i did not have that experience at all when talking and working with him through our situations. Very appreciated for the business and cared about addressing our situations over more than one call in a short period of time. Would recommend.“

“John and his team are rockstars. Extremely responsive, fast, friendly, all around awesome to work with. Thank you!!!“

He took the time with me to help even though he didn't make a dollar in the deal.Thank you, Rick, for the time and if I have an issue I'll be calling you because you didn't just try to make a sale. Thank you.Services: Heating system maintenance“
