We recommend that you have your system checked twice a year; once in the spring and once in the fall.

You can have a loss of refrigerant due to a leak, or you could have a condenser or compressor failure.

This can be determined by having a qualified HVAC professional perform a Manual J load calculation.

Your filter should be changed every month without fail.

Seasonal Energy Efficiency Rating. The higher the SEER rating, the more energy-efficient the system will be.

You may have a refrigerant leak in the system somewhere between the condenser and the evaporator coil.

The unit could be low on refrigerant, the evaporator coil could be clogged or the filter could be in need of changing.

Depending on the SEER rating, you could save up to 40% on your cooling/heating costs.

We recommend setting the dial at 30%. You may want to raise or lower it slightly, however, because every home is different.

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.

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.

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.

Paul

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.

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.

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.
