We got home late Sunday afternoon from vacation and our air conditioning was out…read more We called Precision and Moses Garcia answered our call. He came out Sunday night and figured out the problem. He was able to get our unit running again even though he did not have the exact correct parts. He explained everything to us and came back the next morning with the correct parts and fixed it. We were very impressed with the service, price, and quality, and how professional he was. Highly recommend them.

I'm not a big reviewer, but I had a very not good experience with this very highly rated business…read moreand I feel like warning others is appropriate. We recently purchased a home. The sellers had installed 2 new direct-to-consumer brand (Zokop) heat pumps with 4 heads (2 for each) in the home roughly 1 year ago (they are not providing records, but this is a reasonable estimate). After move-in, we noticed an error on the head unit in our son's room. Precision had previously repaired a broken AC at my small business 2 years ago. It was a good experience then, so I was excited to hire them again. They sent 2 technicians to our house, Edgar and Dylan, to service the units and diagnose. Long story short: Dylan broke the fan in one of the good units, which was maybe a year old (per Edgar's estimation based on some technical detail about Freon...you'd have to ask him) and previously working perfectly. He stuck a probe thermometer in the unit to check its efficiency and then caught the fan blade with it as he pulled it out. There was a CRUNCH and 3 bits of plastic fell out. He said "what was that?" and otherwise shrugged it off. No apology. No taking of responsibility, no solution or assessment offered. Completely unprofessional. I stayed calm, paid for their service, and got them out of my house. They assessed the issue with the other unit to be a Freon leak and quoted for repair. Shortly afterwards, I did a small amount of googling and concluded it was likely the fan. The following week, their office called to schedule the leak repair and I asked to speak to the service manager. His name is Wendell. He asked for a photo of the broken pieces (same one I'm posting here) as well as a photo of the label on the unit, which I also provided. He said he'd see what he could figure out. 1 week went by, I called back, he said he couldn't find anything about the unit or source parts, but if I find the part, they could install it. Not a good solution. I stayed calm and said I would think about it. Here's the thing, I'm also a repair-based contractor. Sometimes, I make a mistake and break something. We're all human, but our mistakes are our responsibility. I can't imagine breaking a customer's perfectly good thing and then just acting like, well, nothing I can do. Total BS. You can't find the part? Buy us a new unit. Too expensive? File an insurance claim. You came into my house, broke a new, working thing, and then left me high and dry. Completely unacceptable. Anyway, I thought about it, decided I don't want these clowns in my house again, and I don't want to keep asking them to act like adults with a sense of responsibility. I hired another company to fix the freon leak. They charged $100 more than what Precision quoted me but also did the assessment and repair the same day. That technician verified these pieces are from the "blower wheel," which is just another word for fan. I still have not resolved the issue with the fan Precision broke. They have a responsibility to make this right, but I'm sure it's on nobody's to do list. Maybe they read their reviews?

Wish I could give a few bonus stars here, beyond 5/5. Just amazing service all around…read more They responded to my request promptly, and it turned out that Sufian was only about 10 minutes from us at the time, so he showed up and got to work. In no time at all, he diagnosed and fixed the issue with our AC drain line and, on top of that, explained everything to me and showed me how to fix this same issue myself in the future. As if that wasn't enough, he pointed out (politely!) that we were using the wrong size furnace filter--and replacing them more often than needed. He told me what size we should be using, and why, and where to find them. I could not be happier with these guys, and will absolutely be using them again for any and all of our HVAC needs.

(In fact quite the opposite as they were very understanding and empathetic!) When we finally had someone over to service our system for the first time he was very punctual, informative, and courteous, honored our coupon, and did a great job! He answered all our many questions, was very detailed, and even followed up with an email suggesting a product we could install ourselves after discussing our request with the owner. He then went above and beyond but I don't want to be specific because I wouldn't want anyone to expect that level of service every single time - I certainly didn't expect it! (It was a great value as we had the HVAC/AC serviced and a new thermostat installed.)

Brenden was exceptional!…read more We just moved into our home. We had a home inspection and our plumbing came back all good! A couple days after we moved in, we kept hearing the most bizarre sounds in the wall. We researched plumbing companies & Cornels came right up. I reached out on a Tuesday and got a response within minutes! We were able to chat via text which was honestly very convenient. They were able to address my concerns professionally & were soooo friendly. I was able to get scheduled the very next day. Wednesday morning rolled around and I got a text with Brenden's picture, which made me feel super safe and even provided a little information about him. He then called and asked if it was a good time for him to head over and gave his ETA. When Brenden arrived he was friendly, warm, and so professional. He was able to easily see what was going on, explain to me in a way I could understand what was going on, and assured me if we still continued to hear the noise to call back. I truly will call Cornels for any of our plumbing or heating needs!! Brenden was wonderful & secured a life long costumer!

This company is going to break your bank. I hired them in August 2025 for air conditioner service…read more The technician said my unit was leaking Freon and too dirty to clean. He said ge would not service it because it will only make it a couple of weeks. They charged me $89 anyways. I called and got a refund since they refused to service it. Nice that they refunded money for service they never performed. They gave me an estimate of over 10k to replace it. I called clean air act. They serviced it up and said it's still has a lot of life left. Now 2026 Chris is texting me wanting to service it on a special of $49. Why? So they can refuse to service it again? They only want to replace units not service them. Here is a picture how they left it last summer. Refused to clean it too. It is still running strong.

While Dane was wonderful in replacing our water heater's anode rod, it was quite bothersome that we…read morehad to pay $250 to have it replaced on a part covered under warranty. The water heater was installed 2 1/2 years ago by Rivival Heating and the anode rod needed to be replaced because "Portland water is so hard and full of minerals". The original quote for labor alone (not covered under warranty) was $340 but we got the manager to bring it down to $250. Still, the water heater is only 2 1/2 years old and that was an expense we did not anticipate when we bought the water heater. The prior one was not broken but when we had Rivival replace our furnace, they strongly suggested replacing the water heater at the same time. The old one never produced brown water but after just two years, the new one did. Maybe the water heater wasn't as good as the previous one? Not sure... Forgot to add, my home warranty service said they could not reimburse me because this is a "warranty issue". And to be truthful, the furnace job was great! Just wish the water heater repair didn't cost me anything. Next year, when it is out of warranty, I'll be able to file for reimbursement from my home warranty provider.
