Sunnyside HVAC: Heating and Cooling in Clackamas County

Furnace, AC and heat pump service for Sunnyside, the unincorporated Clackamas County community along Sunnyside Road between Clackamas Town Center and Happy Valley.

HVAC Service in Sunnyside, Clackamas County

Sunnyside is an unincorporated community in Clackamas County, centered on Sunnyside Road east of I-205 and west of Happy Valley. It is a different place from the Sunnyside neighborhood in Southeast Portland, and this page covers the Clackamas County community.

Most homes here are subdivisions built from the 1970s on. Split-levels and two-story houses on sloped lots near Mount Talbert are common, and many still have their first or second furnace.

Our Happy Valley office at 8305 SE Monterey Ave is about 5 to 10 minutes from most Sunnyside homes, one of the shortest drives in our service area.

Sunnyside Heating and Cooling Services

Upstairs Too Warm, Downstairs Too Cool

Split-level and two-story homes along Sunnyside Road often have undersized returns and unbalanced duct runs. The result is warm upstairs bedrooms and a cool family room.

We measure static pressure, test combustion safety on gas furnaces and check return sizing before recommending equipment. When it is time to replace, we size the new system to the house so the upstairs and main floor stay closer together.

Phil did a great job of carefully examining all the components of our almost 20 year old HVAC system. He took detailed photos and videos to show me the status. And he didn’t try to sell me anything else! Great experience 10/10

Efficiency Heating and Cooling came out to our home to do general maintenance on our furnace and heat pump, and also level our heat pump. Tristan was our technician. His work was efficient and thorough. He explained everything he did and told me what Efficiency H&C had to offering the way of maintenance programs. I am very happy with the services we received.

This was my first time working with this company, and it was an amazing experience! Wayne was super personable, and explained things thoroughly and transparently. The cost was reasonable and that was with the maintenance membership program we joined. Highly recommend this business!

I definitely recommend Efficiency! On this year's hottest day my AC quit working and Efficiency was able to send a technician right out. He fixed it quickly (luckily it was not a major issue) and now I'm basking in cool air. Thank you so much!

Tristan was very thorough with diagnosing the issues with my system and walked me through them so I could better understand my options for repair. We’ve had a few HVAC techs look at our system over the last decade or so, and Tristan was by far the best.

Jason came out for an estimate for a heat pump for my house. He listened to what I was looking for function-wise, evaluated the property, gave me a quote with 4 options, and explained the pros and cons of each. He was thorough, friendly, and not at all condescending (women, if you know, you know). Very professional.

I bought a furnace from these folks over 10 years ago and was very impressed with their work. I've had them tune up my furnace every year since and it's still the great quality and friendly service. They are dependable and knowledgeable every time I deal with them. I highly recommend them.

Efficiency Heating and Cooling is a great company to work with. They gave me multiple options based on personal wants/needs with my 100+ year old house and were patient helping educate me and navigate to a decision. They were prompt, scheduling was easy, very professional, knowledgeable, and walked through with me how my system works once the job was complete. Couldn’t be happier from beginning to end and would heartily recommend them!

Called so many companies to find someone who did duct work beyond cleaning (I had a leak in the duct) and.so glad I got a hold of these guys. Professional, fast, and thorough. Great all around!

Hire them immediately! Super fair pricing, great service. My Technician, Tristian was communicative and thorough. I tried hiring another company prior and they had me pre-pay, after tons of no shows and shoddy work followed by more no shows I demanded my money back and happily gave it to Efficiency Heating and Cooling.

Tristan was very professional. He was on time and explained everything thoroughly. I appreciated the no pressure conversation of future work that could be done with my heating system.

What a great experience with Efficiency. From the estimate process to installation, they made everything seamless and easy. When we hit an unexpected snag during installation, they kept us well informed about what was going on how it might affect the timeline. They got everything done and the system is working great!
