I had to replace my entire ac and furnace system, they were great at communicating the issues and giving me multiple options including different repairs and replacement options, that would work with my budget. They got in to inspect it and had it completely replaced and operational within three days of the first call I made to them. Everyone I interacted with was very polite and extremely knowledgeable in what they were doing. They worked around my work schedule and took a lot of care to make sure my animals were kept safe while working in my house. Overall a wonderful experience and will always recommend them!

Cornell made a tricky water heater replacement in our older home feel manageable. We called Monday morning, Andrew came out that day to assess the tight installation space and talk through our options, and our new water heater was installed Tuesday. Thank you to Andrew, Hunter, and especially Alex, who was thoughtful, attentive, and a real pleasure to work with. We particularly appreciated the care he took to make sure everything was working well before he left. We’re grateful for the prompt response and personal service, and would happily recommend Cornell.

Cornel plumber Juan S. replaced a toilet and a kitchen faucet in under 2 hours. We are very happy with the service and the quality of the products and the work. Juan was very friendly and professional. He left the work areas spotless. He answered all of our questions and gave us advice on best practices for using and cleaning our new equipment. Cornel's is the best.

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.
