Corcoran and Harnist repaired our AC..we were charged 199.95 for a capacitor and 89.95 for the service call. I challenged the cost of the capacitor because Grainger and Lowe’s sells the same one for under 20.00. When Matt from C&H called he said the cost was justified..oh well, live and learn.

Our old furnace stopped working without warning and we weren't happy with our previous service provider. I chose Corcoran & Harnist at the recommendation of a friend and couldn’t be happier. Their prices were very competitive and the installers were both professional and friendly. We will definitely use them again and recommend them to our family and friends.

We use them regularly, we have them come twice a year for check up and maintenance; They do a good work, they do a complete check of our air conditioning unit and make sure that it was running perfectly.

Fine. Still to determine if this was the cause of knocking noise.

Low cost, on time and professional.   Water leak that flooded closet the next day cause by a pipe that was not replaced during initial installation.  They replaced the pipe and saving lots of energy with the new unit.   They did not call the county to do the inspection that was part of the fee.

Everything was great - the technician arrived on time, was very professional, and answered several questions about the system.

Even after sealing our large crawlspace with a thick vapor barrier and installing a drainage system and sump underneath, we continued to have high humidity (~70-78%) in the crawl and connected unfinished basement during the summer and we were concerned about conditions that might be conducive to mold growth.  I obtained two estimates to remedy this. Ken Kuhn came to my home form Corcoran and Harnist to provide a free estimate.  He offered a solution that focused on where the problem was (crawl and basement) and was under half the cost of another estimate I received.  The work was scheduled within a week and the crew arrived on time.  The installers were courteous and meticulous. They installed a stand-alone dehumidifier on a custom pre-made cement/foam palate and installed 10" ducting to ensure the dehumidification reached all the areas of concern. Ken oversaw the work and returned the next week to review the system with me and make sure the completed install looked the way he had planned. We would absolutely use C&H again!
We have a service contract with C&H and their AC service professional has always been professional and on time.

"[removed member name], Glad to here that took care of the problem. We are finding that these Dehumidifiers do a nice job. Thanks for trusting us. Greg Harnist"

I contacted a well known and advertised company (not Corcoran and Harnist)  in the Cincinnati area to conduct annual service on my HVAC system at my newly purchased home knowing that the compressor was 25 years old. The bid from this company was over $10,000 for a 4Ton Heat Pump/dual fuel system using my existing air handler.  I wasn't about to bite on that price without getting additional bids.  I contacted four other companies, each gave multiple options, all of them were about 30-40% lower than the original but each of the presentations were less than confidence inspiring.  I received bad information from more than one, misleading info from others and pure BS from others.  All from respected companies.  I attribute the problems to 'salesman' problems rather than company dishonesty or incompetence.
Then I decided to contact the company I had used to do a heat pump/dual fuel installation 15 years ago at my previous home and had been happy with both the installation and their followup service.  They weren't quite as local as the ones I had already contacted but decided it was not that big a negative.  I called the office and one of the owners was the one who responded and evaluated my situation.  After receiving the original multiple option bid I contacted him once again to evaluate even further options.  He was very responsive and gave me the information I requested. We finalized the discussion on the phone and I ended up going with his original suggestion, a highly rated system, not the newest technology but the one that was going to give me the best return on investment rather than spending thousands more to save a few more dollars on electricity.  Installation was schedule for the following week and the crew that did the installation was very professional, friendly and efficient.  The owner was there when they started and when they finished to verify that they did what we had agreed to. 
I was once again impressed with Corcoran and Harnist and will continue to use them in the future for all service and repair.  I spent a lot of time looking for a more local company rather than calling upon someone that I had a positive experience with but as a result have an even higher opinion of their work.
