I called last night at 10pm and they were out at my house by 1:30 this afternoon. They were coming out to give an estimate to place my a/c unit. Ben was professional, polite, informative and efficient. He was here for less than an hour and had my problem fixed and saved me thousands of dollars on a new unit! I will be using these guys whenever I have a problem with my hvac going forward. They're reliable, dependable, and have integrity! My kind of company!

Our AC wasn't working very well for the first hot days of 2015 so I called Guaranteed since they were local. They were able to fit me in the next day (saturday) which I thought was great since my home warranty provider couldn't send anyone until the middle of next week. A soft spoken technician came to the house and inspected the furnace and the A/C unit outside and said everything appeared fine minus some low freon. He also brought some other things to my attention that could be effecting my home's cooling efficiency, i.e. roof insulation settling overtime, the size of the my A/C unit vs. the size of my home, blinds, windows, etc. There are apparently a number of factors that go into keeping a home cool that go beyond the A/C unit. I sincerely appreciate the additional info he passed on to me. Anyway the freon seems to have solved the problem and I'll definitely keep the other things he mentioned in mind to make my home more efficient. I will definitely call these guys again for service.

Our furnace was out and it was -13 degrees outside so we were desperate, AHS assigned Guaranteed Heating and Cooling for the job. I received a call from one of the technicians named Andrew Tichenor and from the very beginning he was bad. He showed up in a car (no spare parts) not a van and when he walked in from the snow he had no shoe covers nor wiped his feet. He didn't even greet me. I knew the problem was a bad Furnace blower but it took Andrew a half hour to some up with the diagnosis. He proceeded to leave my house with the entire blower assembly. He came back 4 hours later and installed the new unit and when the furnace fired up, you could hear a loud 'whine' noise like an alarm. We asked him about it and he communicated that he heard nothing, our furnace was old and bad (even though I get it serviced twice a year but he didn't know that) and was very rude to my wife and I. Due to the loud whining sound we couldn't sleep when the furnace kicked on, so we called AHS and I called the owner of Guaranteed, Ben. It was a terrible experience. AHS dispatched a second try for Guaranteed and Ben did come out and was very personable, it took him 15 minutes explaining to me what he thought the problem was. And yes, he heard the loud whining sound. He brought us a new blower motor (we weren't sure if the blower motor from before was installed correctly, used one, new?). Ben installed the new blower in my house, was very professional, and when he fired up the furnace, it was very quiet. So I thank Ben but we still have a very bad taste in our mouth on how Andrew Tichenor was so unprofessional and had poor customer service. We believe he did not know what he was doing and installed it improperly. All he needed to do was acknowledge the problem and fix it like his boss but he was a poor service technician.

WOW! I am completely impressed with the service that I received. They were able to come out the very next day! Like the review below, I too was a little concerned about the price/pound of their coolant, however their service call fee and other fees were lower than anyone else I found, which made the overall price for repair extremely affordable! My technician, Ben Dunigan, was fabulous! He was very promt and polite and really knew what he was talking about. I will definitely use Guaranteed Heating and Cooling for any of my future HVAC needs, and highly recommend them to others!

Guaranteed Heating And Cooling out of Grove City is completely unethical. The price they are charging for freon is CLEARLY price gouging. So far we've called 7 other providers (and heard anecdotally regarding an 8th) and they charged us TWICE the next highest rate. When we called to complain they were completely rude and said "Sorry, you approved the price we quoted." Please do your homework before considering Guaranteed Heating & Cooling. I did not and have now found numerous complaints regarding their shady practices. I would not recommend Guaranteed Heating and Cooling to anyone
