HVAC reviews in Columbus, Ohio

Brad did a great job on fixing my mini split. Gave an honest quote and what exactly was needed to get it back to working condition. The service he provided was amazing.

My experience with Dor-Mar heating and cooling was great. The technicians were courteous, helpful and most of all professibnal. Obviously it's never a pleasure to replace such an expensive item like a furnace but Dor-Mar made a little bit easier to swallow (pause). I had reached out to another HVAC company and they wanted twice as much money and was twice as much unprofessional just a money grab. While as a landlord I was in a bind because tenants have to have heat and me as a landlord I had to comply. Thanks Dor-Mar and myself the tenants have heat hopefully for years to come!

Excellent and prompt on call service and great follow up on a problem that took a couple visits to troubleshoot. Jayden, Dustin, Jared and David were all awesome, professional and knowledgeable. Happy to be a future long term customer of Dor-Mar!

In the end your technician was awesome! Explained why why hot water would not ignite. Technician asked for a vacuum and showed us how to fix the problem if it occurred again in the future. As always, this technician is why we have maintained our service contract with you and will continue to in the future. Thanks for the great service including office staff!

I’ve had a great experience with Dor-Mar from the start. Very friendly and easy to coordinate with the office, plenty of warning and advanced notice on calls from the technicians, and overall just a great experience communicating! Tim came out for my latest check up after a refrigerant refill and dye test, showed me the issue from the original install (completed by a different company), and fixed it on the spot. He even took the time to share some energy saving tips and made sure everything else in the house was working well! Would definitely recommend.

If only I could give this company zero stars.

Most recently I was billed for time that:
A. I was told was a free service I had already paid for via text message and
B. Covered time the tech LEFT MY HOME because he was not prepared when he showed up.
Billed for 2.5 hours of service when he was only at my home for maybe an hour and I have video to prove it. But I should be grateful according to Cindy because that was pro-rated!

Wish this was my first bad experience but unfortunately I have given this company $20,000 in business and the benefit of the doubt too many times.

Cindy and Skyler in their main office have been nothing but rude. I’m still waiting a year later for Garret the install manager to call me, (was just told this Tuesday by Cindy he would call me and I am still waiting).

After FOUR install visits and THREE maintenance calls the company magically found the problem I’ve been complaining about once the warranty ran out. Which I would be interested to know when the warranty started the first day of installation where the crew left and didn’t finish the job. The second day when they just didn’t show up or the third day when the sprung on my husband and I they didn’t have the license to finish the work and we had to hire another contractor…. Hmmm Wonder.

I would not send my worst enemy to this company and at this point I’ve reported them to the Ohio.attorney general consumer protection division.

I was very pleased to see how well he did with the removal and installation of our AC and furnace. Arrived on time, straight to work, didn't even take a lunch, and cleaned up afterwards. The system seems to be operating properly and didn't take as long as initially expected. 5 stars!

Jordan diagnosed the problem quickly’ I’m fortunate to have them around!

Dor-Mar is a typical shady American company.
Had furnace installed dec '23 - they stopped working and refused to complete until they had a 3rd person come try to sell us upgraded ac unit.
Was told we get a free service within 6mos.
Get phone call within one month we have to have the city inspect work because they failed their due diligence tasks.
Three months later they send a tech to "Check things out" the guy states "this looks new" had no idea why he was sent to us, I had to teach him, just for him to point out the failures during install (broken handle, clearly incomplete duct taping).
Fast forward Dec 24 and they're charging me 215$ for an annual repair service never wanted or signed up for. [Because Americans LOVE nickel and dime service plans for items said to last decades.]
It took until Feb 2025 to get my refund, and they send a bill stating we're still paying for the annual service.
Yikes. Avoid at all costs.

After 18 years, it was time to replace the hot water heater. Seth with Doormar was my technician that was able to assess the situation and was even the guy to install the new unit. Super knowledgeable and professional. Thanks Seth!

I have worked with Dor-Mar for the past couple years and every time I work with them I am pleased. First, they replaced my furnace back in 2022. They were upfront about the price and extremely timely which is important when your furnace breaks in the middle of the winter. Next up, any time I have called them out for maintenance requests, they are extremely timely, upfront about the costs and fix the problems right away. I highly recommend this company.

Alan took great care of us! Our heat went out right before we sold our home and Alan was able to get it working in time for the buyers to get in before the holidays! He was extremely professional and efficient. Great job.

I booked an appointment online. It closed by "confirming" my appointment time window, but I never got a confirmation email or text. I kept watching for them for 4 hours but no one showed. After reading some of the reviews, I feel a bit like I dodged a bullet. I wondered about it scheduling an estimate on a Sunday...

While visiting the barn in York a few days ago, I happened to notice a Dor-Mar employee casually drinking a beer during what appeared to be a lunch break. While I understand that everyone is entitled to a break, seeing an employee consuming alcohol—especially while representing the company and in proximity to a company vehicle—struck me as highly unprofessional. It raises serious concerns about safety and company standards. I hope Dor-Mar takes situations like this seriously and holds their team to higher expectations moving forward. Do better guys, this is ridiculous, I read through some of the other reviews and everything kinda makes sense!

My service tech from DorMar today was thorough in his explanation of why a cracked heat exchanger is reason enough to buy a new furnace (previous one was 26 years). He was respectful, took his time, showed me his gauges and pictures. Thank you!

Very knowledgeable and thorough technician. Diagnosed and corrected a problem in short order. Will definitely call again.

This company has been a disappointment. I have used them as my HVAC service for four years. In most visits, things have gone OK. But two times (3 years apart) I had them come out for dryer cleaning and both times they sent two different inexperienced teenagers who did not have a ladder that would reach a second story vent nor tools that could clean out the duct, despite both times assuring me they would have the right equipment over the phone after I described the location and height. Two times wasted their time and mine as a result.

Additionally, for my most recent AC check up, they sent someone who left parts of my outside unit scattered on the ground. Complete inattention to detail, which was unsurprising when he instead spent time telling me how Ohio was too liberal. The company seems to hire either contractors or inexperienced people.

Not sure if the wires are supposed to be hanging out after a brand new install of the air handler. The heat pump looks great from what I can tell but I’m not a professional. Otherwise 4 stars for now until I hear back from an install manager. The initial tech that came out was super informative and helped us get the right system without trying to upsell us.

The install techs were quick and were polite

HVAC is now working and wife is happy.

Derrick was extremely professional and educational. Unlike many technicians he truly took the time to help me understand the problem and not run up my bill because I was unknowledgeable. Highly recommend DorMar specifically Derrick!

Brad is the man! Very personable and professional. Not only found the problem quickly but instructed me on how to maintain my system between services. I'll recommend Dormar not only for the service they provide, but because of techs like Brad and their arsenal of service technicians.

Came in for a routine AC maintenance call. For no reason, the technician decided to take apart the entire furnace and then claimed there was a leak in the heat exchanger after supposedly seeing a microscopic scratch. He didn’t perform any other inspections to verify whether there was actually a leak. When asked to leave the home, he refused and threatened to call the gas company to shut off my gas.

How can you declare that there’s a crack without actually removing the part or performing any proper inspection? Obviously there was nothing wrong, but they get paid to sell, so the technician is incentivized to lie.

I’ve been trying to reach someone at the company for months with no luck.
