• I called yesterday to have them come look at our ac unit. The service tech came it and was very respectful. He had all parts on his truck to fix our ac unit. He had us up and running very quickly.

• Wonderful service today from Amanda with Gahanna Heating & Cooling! I put in a request for service overnight and received 3 call backs before 8:30! Erin promised a technician between 12-4. Amanda arrived around 12:10 found the problem and fixed it. When she came upon problems she went above and beyond to get the right parts on Friday afternoon. Thank you!

• Gahanna Heating and Cooling installed a New furnace and air conditioning about 8 years ago in our house. the heating was good , but the air conditioning while running would leak water from the top of the furnace and down the top and side of the furnace onto the floor. I would call them every spring and they would come out to fix this issue. Each time the tech would try different things to fix it.This would work for awhile and start again. Today a different tech came out to service the air conditioner and address the leaking. She (Amanda) was very professional and knowledgeable and did testing that had not been done before, She changed some things an so far It is working well. We are very impressed with Amanda and her work to address the leak. She is a great tech and did a wonderful job on our air condition and furnace.

• Imagine the feeling of my relief of seeing the Gahanna Heating and Cooling van today! Our AC stopped working properly last night and with the heat yesterday and today, the house was feeling a bit warm. Major props to Gahanna Heating and Cooling for a quick fix. Amanda was so friendly and efficient (and pumped to support women in a trade! 👏)

• Ron is a dishonest broker. He sold us an $11,000+ York HVAC unit in 2024 and we've had nothing but problems ever since! One year later, we had to pay an additional $500 for a warranted part, but he neglected to explain that the labor is only covered for 30 days. I've had hair dryers with a better warranty than that. Apparently the product is NOT worth the box it came in. Now another 9 months later and we are having problems again but he won't come and service it! NICE. So we are strapped trying to find another York dealer because he has the market share in Columbus, OH. People! Run, don't walk. Go anywhere else.

• If I could leave a 0 star review I would. I am not one to leave a bad review but this service was insanely horrible. If you need heating and cooling services PLEASE find a different company. During the process of selling our home we had to use this company to replace our heating/cooling system. We were told it would be about 12k for a 1,400sf house. We were given better estimates (by thousands) but the sellers demanded this company. We were told it would be done in a day. When I got home from work the service wasn't done and the techs seemed stressed. We asked many times if everything was alright, eventually one of them told us he wired something incorrectly and didn't know how to fix it. Another tech came to assist (Gabe was so kind & respectful!) They couldn't address the problem so we went without heat and my baby had to sleep at a relatives house. The next day they fixed the inside unit but stated the outdoor unit broke and would not be able to be installed until the following week so we had to use emergency heat. The following week it was fixed. When we brought up the idea of negotiating the price down slightly Ron yelled at my husband and threatened to break onto our property and remove the unit and to not give the warranty. We got overcharged for a horrible service. We had to have my baby sleep in a different house, my in laws had to drive down from Sandusky to be there for them to fix things twice, and we have to pay hundreds extra for the emergency heat charges. Please please please do not hire this company!!!!

• To start, the customer service staff (Erin) and the technicians are excellent. I appreciate the work they did and the support they provided. The one star rating is due to the quoting process and the leadership -- at least the leadership I had contact with. The lack of transparency, high price tag, and inconsistency in quote language are my main issues. For example, I was told that I "had" to get a new thermostat as part of the remedy for my situation. In the quote it included a specific brand/model thermostat, when they came to address my situation I immediately noticed that they were installing a 'Branded' thermostat, meaning it had 'Gahanna Heating and Cooling' on it. This was concerning for me, as clearly they ordered these with their name of it and clearly they were offering/making folks use these. I will be hesitant about doing business with them in the future. Update, 10/28/25: called GH&C due to an issue with the devices they installed, asked them to come inspect. As always Erin was great and scheduled a time. Update, 10/30/25: received a call from Ron, Service/Operations lead, informing me that due to my review they are only coming out to inspect due to the warranty. As a BTC Service Leader, I would have liked for Ron to have asked me about this review and the legitimate concerns I raised.
