Overall great experience with Cornel's Plumbing, Heating & Air Conditioning. It first started with an inspection of my old units which were getting close to 20 years old and I could tell they might be losing steam. Don came out to look over everything and pointed out that the AC unit was running colder than expected which meant the furnace was probably not in the best shape either. Sure enough he inspected the furnace and found more problems. Don was informative, kind, and very helpful. He pointed us towards David who help spec out what a new set of units would like and provided prompt estimates and answered any questions I had. Due to circumstances David was able to coordinate a next day install of the new units and maintained great response times and updates during the whole process. During the install I met Jace and Victor. Jace was the lead technician on the install but both he and Victor were meticulous in their work and got the job done with no issues. The next day and after some consideration I decided to replace my higher end filter system with a Media filter and David was helpful enough to coordinate Jace to come back out the following week and quickly switch out the filter system. I would recommend Cornel's to anyone looking for a team of high quality technicians who take pride in their work and deliver on their promises.

Cornel's did a nice job of replacing our old hot water heater. It had been part of a geothermal ground source heating system installed when we built the house in 1997. The hot water function of the system had been isolated to run separately a number of years ago, but now the tank was giving out.
There were some details at first for the plumbers to understand what was involved in fully separating a new heater from the old system. We also wanted a heater that was a bit more than just a standard stock model. Once that was understood so they could write a quote, things got underway.
Brendan arrived the next day pretty much as scheduled. Very nice, caring for the situation, we had a review of the work while looking at the existing equipment. From that point, I left him to do his work. I believe it was about 3 hours later that he was done. It all looked so much better, and it's been running just fine.
After Brendan was done, we sat in the kitchen and discussed any minor details. He was very nice and reassuring about how everything seemed just fine, and to be sure and contact them if anything did come up. We paid the bill, and he was on his way.

Cornell‘s plumbing provided an excellent service and experience for us. We took advantage of a water heater service special. Kevin Van Dyke serviced our exterior tankless Gas hot water heater. He was personable and very professional. Kevin explained exactly what he was going to do and even gave professional tips on how to care for our hot water heater and keep our plumbing system clean and flowing. He even provided pictures and video of his work to further prove his honest and thorough expertise. I would trust Kevin to service our system again… he was great! Thank you Kevin Van Dyke and Cornel’s Plumbing.

Alex and Juan came out and promptly replaced a leaking faucet. Very clear with the options and pricing, replaced quickly and efficiently. Communication was excellent. Will be using again.
Edit: scheduled a furnace tuneup and turned out the original 20+ year old furnace needed to be replaced. Nate walked us through everything that was going wrong with the furnace and several different options for repair or replacement as well as deals and payment options. No one wants to get hit with this bill but he made it as painless as possible. Super friendly and respectful, transparent and personable.

From the time I ordered a new water heater to installation being fully completed was less than 24 hours. Super easy process and experience all around. James was the install tech and he was polite, clean, articulate, and knowledgeable. The price was competitive too. I wholeheartedly would use Cornel’s again.
… and no, they didn’t pay me or reduce my costs to post this.
