  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.

  I had my HVAC installed by Gahanna Heating and Cooling just one year ago, and now it is making a horrendous noise without me doing anything to it. When I called for help, the receptionist on the phone was dismissive and completely unhelpful with scheduling. Even though this was an urgent issue because the unit isn't working properly, she didn't offer to send anyone out for two full days. They couldn't even give me a specific appointment time, only a vague 4-hour window that ended at 4:30 pm... not feasible for anyone working a normal day. Her snobbiness and inflexibility were totally unacceptable. Thankfully, a technician came earlier than expected and he was lovely. But despite the unit still being under warranty, they wanted to charge me over $1,000 just for shipping and labor to replace a blower and wheels. They also told me no financing options were available. After looking up prices online, it's clear their markup is outrageous. It is nowhere near this cost at other places. When I brought this up, they were extremely rude and dismissed me as a customer. I am truly baffled by Gahanna's excessive pricing, rude and inflexible customer service, and apparent lack of loyalty to their customers. I strongly recommend NEVER using this company.

  Gahanna Heating and Cooling took $15,000 and left us with malfunctioning equipment For details, I received quotes from four companies in the area and selected Gahanna Heating and Cooling because they seemed to understand the scope and scale of the project and were willing to discuss options. They were approachable and seemingly intelligent on HVAC issues and weren't just trying to sell us. They were not the cheapest and part of the reason they were selected is because they were on Mitsubishi's list of approved installers. We agreed on a contract in March and agreed to delay installation until weather was better since we would be without heating for several days and to accommodate their schedule. The installation began April 8th through April 10th and continued April 15th through the 17th to install a mini-split system with three indoor units and one outdoor unit (Six days). A week after the install, we were able to actually test the system because the temperature warmed up. The indoor unit was covered in ice and the room felt like a walk-in cooler and it was making a terrible sound intermittently. They came out and inspected the system and said the levels were all fine and the tests came back normal. (Day 7). We then paid the full amount assuming that any issues were addressed. A week later and same issue of noise and icing and also water was dripping from the indoor unit onto the floor. They came out with an expert on mini-splits and recharged the system with refrigerant and again and said all tests came back normal. (Day 8). A week later, same issue of loud noise, icing and inconsistent temperatures where one unit is cold and never turns off and other units are blowing out warm air. A tech came back out and found that the wires for two of the indoor units had been crossed during installation. That was fixed and the levels of refrigerant were checked. (Day 9). When we could test the system again, we had the same issues of excessively cold air in one room and warm air in another. Gahanna came back out with representatives from Trane and found no issues with the system other than the pumps and could not recreate or diagnose an issue since there were no codes in the system. (Day 10). We had to purchase window units since this was during the peak of summer. A month later, new pumps and wireless thermostats were installs and the issues persist (Day 11). It's been nearly five months without an operable system. It cannot regulate the temperature and randomly produces excessively cold or warm humid air and the vanes and fan seem to reset themselves. I've held off on this review because I wanted to give them the opportunity to fix the issue. However after 11 days, five months and now they've stopped returning my calls or emails I'm left with no option. We're tired, frustrated, hot, and out a lot of money and time. Our only hope is that we can help others avoid our mistake. Stay away from Gahanna Heating and Cooling or retain a lawyer.
