It turned out I had a major problem (someone had tried to steal my outside unit and had cut all the lines). East side was awesome, made the time to fix and get it running, and worked super efficiently and were patient with all my questions. I would recommend these guys for sure. Were great to work with.

Adam S.

We had an issue with our A/C unit and Fernando explained all the options up front when I made the service call. Caesar came out and completed the repair. He was upfront, honest and didn’t try to over sell me- which is greatly appreciated. Would definitely recommend.

Erin N.

These guys are great and reputable! Almost got scammed by another HVAC company… these guys saves the day!! Don’t buy a new unit until these guys have a look at it.

Cory M.

Had Eastside clean and service my furnace and AC unit today. The technician was very friendly and capable. I have had Eastside come to my house a number of times over the years, for repairs and servicing. Always the same positive experience with very good, honest service and reasonable prices.

Tom S.

Ceasar, was on time, professional and knowledgeable. His inspection was thorough, and he kept me updated throughout the process. He was efficient and answered my questions. I would highly recommend this company to anyone in need of heating and/or AC service.

Philip A.

Eastside just checked and serviced my furnace and AC. The technician, Cesar, who came was great; very professional, thorough, and friendly. He didn’t rush through it and addressed the concerns I had. I’d recommend Eastside to anyone.


First time customer of Eastside Heating & Air and we were very pleased. Cesar was friendly, honest, and knowledgeable. Will use again and would definitely recommend based on price and service!
