Reviews of local pros in Fairfield, Ohio

We had an AC condenser go bad and called Hill-Air for a service call. They were able to schedule a service visit within 2 hours of the call. Chris, technician, was very courteous, professional and explained in details what was causing the problem. The repair was done quickly and the AC unit was promptly working again.

I highly recommend Hill-Air for quality and service promptness.

I would give the installation and product five stars. My rating pertains to the customer service. If a business doesn't have a friendly, professional front office that supports its customers, then you're subject to years of pain every time you need service, or finding another company to do your maintenance. Neither is great. Ideally, you would like to work with the company that built your system.

Hill-Air were prompt in getting over to my property and help assess one of the commercial units. They triaged the compressor and installed a $550 capacitor in the process, but that did NOT fix the issue. They left with the unit still not functional and asked for another service call with 2 people. I should have refused to pay them for the part and had them take it off the unit because I am having to replace the unit. I primarily called Hill-Air to give me a second opinion on fixing the unit and to work me up a replacement quote. They came back with a quote for $42,000 with very little detail in the quote as to why!!! Of course that is a ridiculous quote for a 3 ton unit. I decided to stay with the HVAC provider that had installed and maintained the units at the property. His replacement quote came in at roughly $13K for a Carrier 3 ton, including a custom curb adapter. Must say I just feel ripped off by Hill-Air… will not be using again.

Very disappointed in both the customer service and technical aspects of this company. After our HVAC unit started showing error messages on very hot days, we hired Hill-Air to troubleshoot and do a repair. Other than the intermittent error messages/lockouts, the unit was working fine. They recommended replacing a sensor, which they completed last week. Almost immediately after that repair, the unit stopped functioning normally. It would be set for 69 but running at 75. We have a newborn and it’s the middle of a heat advisory, so I contacted them to come back out and fix whatever had apparently gone wrong during the initial repair. The technician came back and said the unit needed cleaning and that was the only issue. I pointed out that the unit had been running fine at baseline before the repair, so it appeared to be a result of whatever had been done at the last appointment, at which point he became condescending and spoke over me, cutting off the conversation with no solution other than “it’s dirty.” I decided not to argue with him further and said I would contact the office. After being “fixed” by this company, my AC unit is working worse than it was before.

EDIT: Had another company come and check and the issue was in fact NOT caused by the unit being dirty. It continues to be a sensor issue that was not addressed or fixed by Hill-Air despite them happily charging us hundreds of dollars. And let me be clear in response to their statement - I was not offered any cleaning for free. It was a full price cleaning. And again, this did not fix the issue. The issue is their shoddy and non-thorough work. Avoid for any complex HVAC jobs, they will not be able to help you and their customer service is a 0/10.

Have used Hill Air for routine service since they installed our geo thermal system 9 years ago. They are always professional and efficient. I highly recommend them.

My furnace and AC were installed by Hill Air. I always have my yearly maintenance for my heating and cooling done by Hill Air as well. I find the technicians to be professional, courteous and engaging. I would recommend Hill Air for any of your heating/cooling needs.

I have an oil furnace which requires correct maintenance, and I'm very very pleased with the efficient, friendly, effective, professional, courteous, and helpful associates with Hill Air. I am pleased to have the fall and spring maintenance plan at a very reasonable price.

The only company in the Cincinnati area that offered me the correct product! Every other company, large scale and independent, was incompetent. THEY ALL TRIED TO SELL ME A HEAT PUMP EVEN THOUGH IT IS INCOMPATIBLE WITH MY LINE SET (1/4in). I spoke to 10 companies total. Hill-Air was the only valid choice.

My experience with Hill Air was exceptional. Roy Hall was a great influence determining what furnace to purchase. He also a good teacher. The install was done on time a professional

Chris did a great job! He was professional and friendly. Hill-Air has been servicing my HVAC system for many years and I have always been extremely satisfied with the service they provide. I highly recommend them.

Hill-Air’s installers did excellent job installing my daughter’s new HVAC system (gas furnace and AC). The workmanship is amazing. My daughter’s home in a two story building with a finished basement. My daughter is gushing about how her home is so much more comfortable this winter and at a lower temperature.

Nice prices

After using many local repair companies this is my new go to. They care about their customers, will come same day do you don’t have to be without AC overnight. When they couldn’t fix it they brought us potable AC units. That is just one example of the many ways this company goes above and beyond. Also very professional, honest and trustworthy. I can’t remember a time I’ve liked a company this much.

Good experience. Installers very professional and walked us thru what they were doing. Cleaned up after they were done they were done in a timely manner. Would not hesitate to recommend them to friends.

In my opinion and observation, the Tech was quick fair and professional. I will be calling upon them again for future troubleshooting and maintenance for my HVAC System.

Luke was great, unfortunately it cost me $100 and there was nothing wrong but I understand having to charge for call.

Chasity came out today for an A/C system checkup and did a great job. She genuinely cared and was very informative and knowledgeable. This was a 5-star service.

They were able to schedule me same day, accommodate my time frame. The tech was punctual, knowledgeable and friendly. I will absolutely use them again.

The service was excellent, He gave clear direction on install and maintenance, very professional, cleaned up behind themselves at the end and made sure everything was installed properly, was very patient with my questions and answered them clearly. Great job fellas!!!

This company is wonderful, will only use them from now to always. Very professional, prompt, knowledgeable. They put in a furnance for us in no time. I think they should be rated 10 or higher

Brandon was absolutely amazing, he worked very hard. You guys should be very proud!
