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 10/10System inspection

ViewEvery Tool to Clean Your Indoor Air
1. AIR CLEANER
Your standard furnace filter only grabs large dust particles - the fine stuff passes right through. An advanced whole-home air cleaner captures microscopic particles including smoke, bacteria, dander, allergens, and viruses. We carry multiple MERV rating levels to match your needs. For smells and odors that filtration alone can't catch, we pair it with our odor removal services.
2. UV LAMP
UV lamps kill mold and organic growth on the indoor evaporator coil - the wettest, darkest spot in your system. Mold builds up there because the coil collects moisture every time the AC runs. A UV lamp prevents that growth and keeps your air cleaner.
3. VENTILATOR
Ventilators bring filtered fresh air in from outside while pushing stale indoor air out. Heat recovery ventilators (HRVs) capture heat from the exhaust stream to pre-warm the incoming air - so you get fresh air without the energy hit.
4. HUMIDIFIER
Portland winters dry out your indoor air more than you'd think. A whole-home humidifier adds moisture back in - stopping dry skin, static shocks, and the cracking that happens to wood furniture and hardwood floors.
What Portland Air Throws at Your Home
Wildfire Smoke
August through September, AQI spikes and PM2.5 from regional wildfires make Portland air some of the worst in the country.
Pollen Seasons
Three pollen seasons hit Portland hard: trees in spring, grass in summer, ragweed in fall. If you deal with allergies, you already know how bad it gets here.
Mold & Mildew
165 rainy days a year plus damp basements create ideal mold conditions. Our mould removal services tackle it at the source.
Pet Dander
Portland loves its pets, but pet dander accumulates fast and standard filters can't keep up. Our allergen reduction systems make a real difference.
VOCs
New construction, paint, and furniture constantly off-gas volatile organic compounds. The same system behind our smoke odor removal service neutralizes them before they build up.
Dust Mites
Our Pacific Northwest humidity levels are perfect for dust mites. They thrive in the same conditions we live in.

Reviews from Portland homeowners
A few recent Google reviews from homeowners across the metro. We don't edit them.
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.Furnace & heat pump maintenance
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!Maintenance membership
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!AC repair
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.System diagnosis
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.Heat pump estimate
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.Furnace install & tune-ups
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!100+ year old home
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!Duct leak repair
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.HVAC service
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.Heating system service
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!System installation
