Our furnace went out and I called these guys and Zack was here on time (actually early). Our furnace is 30 years old and he said that it needed a new ignitor switch that had to be ordered and it would be a couple of days. after calling the company they said they could get it here next day! Zack explained that this might work or it might not and I explained that we will be selling this house in the spring so I really didn't want to invest in a new furnace unless I had to. Next day Jordan arrived with the part and he installed it and with my fingers crossed we turned it on and it worked!!! YEA!! Both of these guys were great to work with and I highly recommend Corcoran & Harnist! They were very professional and knew what they were doing! read more

They have been taking care of my mother in laws condo for years. She was happy with them. They really like Liz and feels she is honest, reliable and very knowledgeable at her job. Today was the 2nd time at my home. They do a great job. I completely agree with the way Liz works. I would highly recommend if your looking for heating or air needs. Thanks Liz. read more

They charged me $330 for a ​replacement limit switch. The part itself. Not the labor. ​​​Upon research, this part is only $15-30 retail. Labor was the additional ​​​$89 for the service call. ​​Over $400 bill for a half hour of work? Good grief. I expect transparency. C&H may have the skills to fix your system, but I expect honesty. I'll be going with a different company next time. ​​​ read more

No one ever wants to make the call for an AC repair, but sooner or later it happens. When it's your turn to make that call, I strongly recommend that it be made to C&H. Dave could not have been more professional in the performance of every aspect of his job from the moment he entered my home until his departure. He donned protective slippers immediately upon entering my home and explained in great detail the nature of the problem after a thorough diagnosis. He then checked to determine that the defective parts were still under warranty and was able to secure them and have them brought to my home in a minimum amount of time. Dave completed the job quickly and efficiently. Displaying the ultimate degree of professionalism, Dave is highly experienced, knowledgeable, and personable as well. He was most respectful of both myself and my home. Like most consumers, I was wary of an inflated bill, but Dave gave me an itemized statement of the cost up front and I was pleasantly surprised at its reasonableness. Kudos to Dave and C&H, along with my highest recommendation! read more

Got 5 bids for AC replacement. Professional presentation, but their bid was by far the HIGHEST price ... insultingly so. Do you due diligence and shop around! read more

Have worked with them for years. Can get in same day in an emergency and quickly otherwise. I am very happy with their service.

Yesterday they replaced our air conditioner, which they had replaced last summer. The unit they used last summer was the exact size of the unit it replaced. It did not, however, keep the house cool. Tim Corcoran discussed the facts with me and he decided they needed the next size larger. He admitted he could not get it in place in time to make much difference last summer, but promised faithfully he'd have it done before the season this year. Lo and behold, the new unit is in (at ZERO additional dollars) and runs - still too cool in March to be sure it will keep the house 75 degrees, but with a stand-up guy like Tim Corcoran standing behind it I'm not concerned! Call Tim - it's like having your brother-in-law doing your HVAC! (the good one, not the 'shyster') read more

The service with C&H was beyond stellar...from the immediate engagement within 15 minutes of our emergency call of our air conditioning failing (On a Sunday no less), to the professionalism of the installation team (thank you Brian and Bennie). Lastly, the personal visit from Greg Harnist who thoroughly explained the process along with the maintenance routine after the unit was installed sealed the lasting impression and trust of our future business. read more

New house, new furnace/AC. Ugh! We shopped it out to three different companies. Corcoran & Harnist got our business. Here's why. Price. They were the best price by a fair margin. Obviously this is a big factor, but I'm glad to say it never felt like a cheap company. Professional. Their salesman wasn't pushy. This is huge for me. I hate hate hate the hard sell. He gave me all the info, answered my questions, double-checked I had his contact info and then left. That's the right way to do it. Courteous. Their installers asked before they did anything that might disrupt my family. It was actually a little funny how deferential they were. Still better to have them ask often rather than not at all. Thorough. After the installation I had to have them come back out to fix a link in some ductwork. On their dime, he spent an hour searching for that leak and plugging every possible spot it could be. They also took care of all the paperwork for me to get my Duke Energy credit. If you ask people on the West Side of Cincinnati, chances are they've used, or know someone who has used Corcoran & Harnist. They'll tell you, too. They are a top-notch company! read more

who DOES that!? Corcoran & Harnist guys just spent most of the day replacing our AC unit, running the lines through the open ceiling in the studio - which is painted black. They went out & got black spray paint to paint the lines without asking, just knowing it was what we'd want. :0 they're not allowed to be that cool are they!?! read more

Chris was able to fix the steady drip in my old boiler/radiator system. And he didn't over charge me.

Love our new quiet furnace. Appreciate C&H's professionalism and knowledge. Installation was done in a manner that gave us great confidence in the product, the installation and explanation of what they were doing and why. Cleaned up every little piece of debris, covered/protected our beautiful wood floors and did it all with little interruption to our routine. Appreciate it, C&H read more

I replaced my whole house air conditioner June, 2019. Tim Corcoran was very fair and honest in setting his price. They started the work when promised and completed it on time. The crew was friendly and all that anyone could ask for. I talked to five different AC contractors before contractors before selecting Corcoran & Harnist. They were the most straightforward. read more

I was very happy with my service from Corcoran and & Harnist - until I used my good sense to get a second opinion. My home is an older home with two HVAC units - one upstairs and one downstairs. The upstairs unit was not cooling. The technician was courteous and kind, but had to deliver the bad news - the unit had to be repaired ($2000) or replaced ($3000) because of a likely leak in the coil. "Hmm, that's funny", I said, "We recently purchased the house, and the inspector said nothing of the sort". He said it was for the better, as the older Freon is being phased out. Mixing truth with fiction - he's good. Well, I got a second opinion, from a different company. That technician came out, sprayed some soapy water on the Freon hose connection outside, determined that the bolt had simply come loose at the base of the exterior fan unit. Pumped a few pounds of Freon into it, and it has been running like new for 4 months. So, wouldn't an honest company have diagnosed and fixed my immediate problem and THEN given me the option of thinking about a newer system? I've never written a Yelp review, but this one was prompted when the Corcoran & Harnist collections assistant tried to convince me that her technician did everything right, and could I please pay them the extra fees they slipped onto my bill? I live in Northside, so I'd like to help out my side of town, but I'd keep searching if I were you... read more

Professional people! Just had a new furnace installed and these folks are pros at what they do! I'm a nit picker, but have nothing bad to say about Corcoran and Harnist. From the ladies in the office, the sales rep, to the guys in the field...all take pride in their work and are extremely polite. I'm looking forward to a long business relationship with these guys and gals. Again, great job! read more
