Cliffs has installed both my furnace and just recently my air conditioner…read more The two guys that did the installation were both great. Chris was the name of one of them, I didn't catch the others name. Leah in the office is very helpful too. I had my air conditioner looked at Wednesday, called Thursday morning to see when they could install and before dinner time I was enjoying a cool house. Everything went very smoothly and I could not be happier.

Much to my surprise I rec'd a voice mail from RussCo that they were in my area now! UNBELIEVABLE!!! A very polite and well skilled service person named Bill arrived in minutes. First Class Service, checked the unit, adjusted a contact and it is working fine. Outstanding service and Bill is very knowledgeable. A totally positive experience. DO NOT HESITATE TO HIRE RUSSCO!

I would not recommend this business to anyone who is looking for professional, knowledgeable,…read moreprompt service. I was looking to have our boiler system repaired, first technician said it was a bad ignitor, which it was not. Second technician said it was a bad pressure switch, which was ordered and installed. Boiler ran constantly and would not shut down, even after thermostat temperature was attained. Third diagnosis was another switch (since the first one installed was incorrect). After that installation boiler ran constantly, without burners ever coming on. Total incompetence, with no apologizes. $500 dollars later, and still no functional boiler. We called RCM heating who came out that day and had the boiler properly fixed and running within an hour! Do not call JTR unless you want to waste your money! Mr. H

First off let me start by saying Andy is truly a life saver…read more Over night the blower motor in our furnace went out and smoke started coming through the vents. The fire department was called and we (me, my wife, and our 3 kids) were without heat on a 20 degree night. The following morning I made a few inquiries just hoping to get something scheduled and I was surprised to find they had someone available almost immediately. The estimate fee (only $75) was waived once Andy informed us what we needed, 1 hour later our house went from 65 degrees to a comfortable 74. Thank you so much. I would HIGHLY RECOMMEND them.

Our furnace shut down on one of the coldest days in December and Andy responded quickly to the…read moreservice call. Andy did a great job at figuring out what was going on with our furnace, explained the options to fix what was needed, and did the repairs that were necessary. By also figuring out that the gas meter was the issue that needed to be taken care by our gas service provider, Andy saved us so much money on unnecessary repairs because the initial issue was outside the furnace. This is the second time we've used Specific HVAC and I will continue to call them for any future repairs. Andy is friendly and provides quality service.

Everything was done with professional workmanship. One air conditioner which was replaced did not work properly. I called them and someone was sent out to assess the unit.

10 out of 10 recommend Kent, especially for new construction! Amazing office staff, easy bid…read moreprocess, fair negotiation, and the install team was so respectful! They left no trace and alway cleaned up their materials! Alex B and Zack were the two installer we had and they are the dream team! Holly M (Director of Customer Engagment) caught wind that I was going to build and reached out to ask if Kent could provide a HVAC bid, and I'm so glad she did! She put me in contact with Bob and he made the bid process so easy. I had a finalized/signed bid in less than a week and we were able to negotiate a few other items that we wanted! I reached out to Bob via telephone with questions and he was prompt with his response. I found out later that he was actually on vacation when he responded! Holly also hand delivered information packets about the equipment we would be getting installed. The customer service is top-notch! Kent was my favorite company to work with during the new build. I was able to be on site while all the trades were there at the same time, and the Kent team was always the first to greet me when I arrived! We got the runaround from the other trades about when they would start on our home, but as soon as we gave Kent the green light, they showed up and started exactly when they said they would. This was the first time my contractor worked with Kent and he was so impressed. I was unable to be at the initial walk-through, so Holly and Alex made a special trip back out to the house to FaceTime me and make sure I was informed of the plan! They walked through every room, gave me their feedback/suggestions, and answered all my questions. I was confident that I was in good hands! The walk-through was on a Friday where they laid everything out then Alex made the ductwork on Monday and they were off to the races on Tuesday. I can't thank the install team enough, they were working in below freezing temperatures to get the job done! Kent really is a well oiled machine! The new owners, Stacy and Glenn know exactly what they're doing! New construction is full of twist and turns but I want to give a huge thank you to Holly, Bob, Alex, Zack, and Stacy for making this experience the easiest and most smooth part of the construction process!
