- I just wanted to thank Jake & Colby of Cornel's Plumbing, Heating & Air Conditioning. They did such an amazing job for us today. Completely … view more replaced our water heater in just 2 hours. They were very polite, knowledgeable and just plain good guys. 5 stars for sure.
- Cornell Plumbing and Heating ANSWERED THE CALL! Our furnace crapped out in the winter, it was 20+ years old so we knew it was coming but put it off until … view more it died. We were freezing for less than a day before Cornell quickly responded to our request for an inspection to see if the furnace was fixable. The inspector was very thorough and helped us understand all of the issues with our dead furnace and quickly got us connected to Randy who came over in a matter of minutes to walk through the options. Randy was very very knowledgeable and so friendly. I never felt pressured when talking to him, he was very practical and honest about what would be the best bang for our buck, while ensuring we had a solid heater for decades to come. We were on the fence about installing central AC (our house was built in 1890) but the summers in Portland have gotten so tumultuous that every year for the past four years, we've shopped around for AC quotes but just couldn't afford to commit. Randy built a great package for us that added AC to our furnace for a price that was very reasonable, so, we did it! We have a two year old and a baby on the way and we are very very thankful to know we have cool summers ahead of us and warm winters to enjoy in the comfort of our home. It's been night and day with the new furnace compared to what we were working with before. I never knew how warm our home COULD have been, until we got our new furnace installed. Oddly enough, our neighbors furnace also died like a week later and he saw we had Cornell over and asked about our experience. We were very quick to highly recommend Cornell, and my neighbor also got a new furnace from them! Needless to say, it was a smooth, quick and satisfying experience, you know, as satisfying as it can be to have to suddenly invest in heating and cooling, which can be many tens of thousands of dollars... but with the right folks, and the right system, the experience can be a sort of blessing in disguise - which it was for us!
- Jake was super helpful getting us a new water heater installed today after our very old one went out over the holidays. He was timely and tried a few other … view more solutions before we decided to fully replace it.Jake was Super kind and made sure he fully explained both the issues and the functionality of the new unit in ways that made sense to us and helped us feel confident in not only him but also Cornel’s as a whole. We will definitely keep using them for our heating and AC. Thanks Jake!
