Why make the conversion from oil to natural gas heating?

  • Convenient – You don’t need to monitor fuel levels or schedule deliveries and you’ll never run out of natural gas in the middle of a blizzard.
  • Cost Savings – A gas furnace or boiler is approximately 25% less expensive to operate than an oil alternative of the same fuel efficiency. You can also take advantage of a high-efficiency option for further savings.
  • Less Maintenance – Oil releases particulate matter during the combustion process that can clog the system, requiring frequent service, whereas there’s nothing more than filter changes and annual maintenance necessary to keep your natural gas furnace operating at its best.
  • No Tank – Utilizing a central distribution system, natural gas requires no large, unattractive tank taking up space, detracting from aesthetics and requiring upkeep.
  • Reliability – Count on natural gas to operate during emergency conditions due to supply via underline pipes.
  • Versatility – With natural gas available, you can use it for drying clothes, water heating, cooking, heating the swimming pool or the barbecue grill.

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.

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.

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.


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.

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!

Scott P.

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.
