Upgrade Your Air Quality: New AC installation is the perfect time to add whole-home air purification for wildfire smoke and allergen protection.
From your first phone call to enjoying cool air, here's exactly what happens during a professional AC installation with Efficiency Heating & Cooling.
A comfort advisor visits your home to evaluate your cooling needs. We inspect your existing HVAC system, ductwork condition, electrical panel capacity, and outdoor unit location. We measure every room, check insulation, count windows, and note sun exposure. This isn't a sales call. It's a thorough engineering assessment.
Based on our assessment, we design a system tailored to your home and present 2-3 options at different price points. Every proposal includes equipment specifications, total installed cost, available rebates, financing options, and projected energy savings compared to your current system.
Once you approve a proposal, we pull the required mechanical permit from your local jurisdiction (City of Portland, Clackamas County, Washington County, etc.). Oregon requires permits for all HVAC installations. We handle all permit paperwork and scheduling.
Our NATE-certified installation crew arrives with all equipment and materials. We protect your floors and walls with drop cloths, remove the old equipment, and install the new system according to manufacturer specifications and Oregon mechanical code requirements.
After installation, we thoroughly test every aspect of the system to ensure it's performing to manufacturer specifications. This step is critical, studies show that improper commissioning is the #1 cause of premature AC failure and reduced efficiency.
We walk you through your new system, showing you how to operate it efficiently, change filters, and recognize any issues that need attention. You receive complete documentation including warranty cards, permit receipts, and maintenance schedules.
The local building department schedules a permit inspection to verify code compliance. We coordinate with the inspector and address any items if needed (rare with our installations). We also follow up with you after the first week to make sure everything is performing as expected.

Expert insights from our Portland HVAC professionals
Not sure which system type is right for your home? Our AC buying guide compares central air, ductless, and heat pumps with Portland-specific pricing and rebate information.
Central AC installation in Portland starts at $6,995, and premium variable-speed systems top out around $12,500. Ductless mini-splits start at $5,995. Costs include equipment, labor, permits, and refrigerant. As an Energy Trust of Oregon Trade Ally, we confirm current incentives in your written estimate.
AC size depends on square footage, insulation, ceiling height, and Portland's climate. Most homes need 20-30 BTU per square foot. We perform Manual J load calculations to determine exact size. Oversizing reduces efficiency and comfort; undersizing can't cool adequately during Portland heat waves.
AC installation typically takes 4-8 hours for central systems, 2-4 hours for ductless mini-splits. The process includes equipment setup, electrical connections, refrigerant charging, testing, and cleanup. We schedule installations during weekdays for fastest completion.
Yes, we specialize in ductless mini-split AC installation perfect for Portland homes without existing ductwork. Ductless systems provide zoned cooling, quiet operation, and energy efficiency. They're ideal for historic homes, additions, and rooms needing individual temperature control.
Energy Trust of Oregon offers rebates up to $3,000 for qualifying high-efficiency AC systems. Point-of-sale rebates and utility incentives can reduce installation costs by $500-$3,000. We handle all rebate applications.
Heat pumps provide year-round comfort in Portland's mild climate. They cool in summer and heat in winter from one system. With Portland's average lows of 30-40°F, heat pumps work efficiently. They often qualify for higher rebates and provide better overall value than separate AC and furnace systems.
Portland requires minimum 14 SEER for new AC installations. We recommend 16+ SEER for energy savings. Higher SEER ratings (18-21+) provide better efficiency but cost more upfront. Energy Trust rebates often require minimum SEER ratings for eligibility.
Yes, special financing is available with approved credit, with convenient monthly payments. Income-qualified households may have additional options. Contact us to find out which financing options are available to you.

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
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
