Need AC repair in Portland? If your air conditioner is blowing warm air, won't turn on, or is leaking water, Efficiency Heating & Cooling can usually send a NATE-certified technician the same day.
The diagnostic is $189, and it is applied to the repair if you go ahead. We quote the repair before any work starts, with no overtime charges. Licensed in Oregon (CCB #187834) and serving Portland and nearby cities since 2008.
AC repair calls in Portland usually start with something you notice. The vents blow warm air, the system won't turn on, water collects around the indoor unit, or the outdoor unit makes a new noise. These problems usually get worse the longer the system runs, so an early call often means a smaller repair.
Most of those calls become same-day visits. The technician runs a full diagnostic, finds the cause, and explains it in plain language. Our trucks carry the parts that fail most often, so we usually finish the repair on the first visit.
The diagnostic is $189, and we apply it to the repair if you go ahead. We quote the repair before any work starts. We charge no overtime for evenings, weekends, or holidays, and emergency calls are taken 24/7.
A NATE-certified technician completes every repair. We are licensed in Oregon under CCB #187834 and have been in business since 2008. Our headquarters is at 14913 SE Kellogg Ave in Milwaukie, with offices in Portland and Happy Valley.

Low refrigerant, a frozen coil, or an outdoor compressor that won't start can all stop cooling. We find the cause and restore cooling fast.
An AC that keeps turning on and off wastes energy and strains the compressor. We repair the sensor, capacitor, or electrical fault behind it.
Grinding, squealing, or banging usually points to a motor, compressor, or belt problem. A hum with an outdoor fan that won't spin often means a failed fan motor or capacitor.
Low refrigerant cuts cooling and can damage the compressor. When we find a refrigerant leak, we repair it and recharge the system to the right level.
Check the thermostat and breaker first. If both are fine, the cause is often a failed capacitor or a contactor that's stuck or clicking in the outdoor unit. Both are usually same-day repairs.
Hot and cold rooms usually trace back to duct problems, low refrigerant, or weak airflow. We find the cause and balance the system.
Step-by-step diagnosis for common AC problems. If the issue persists, book an AC repair visit and we'll get it sorted.

Portland summers used to be mild enough that many older homes were built without central air. That has changed, and the equipment now in those homes gets pushed hard during heat waves.
In late June 2021, NOAA reported that Portland set all-time heat records three days in a row, reaching 116 degrees on June 28. An AC sized for a typical Portland summer runs nonstop in that kind of heat. Weak capacitors, worn contactors, and dirty outdoor coils that got by in July of a normal year fail under that load.
The same pattern shows up in smaller heat waves. A system that has not run hard since last August starts up on the first 95-degree afternoon, and a part that had been slowly wearing out finally quits. Cottonwood fluff and pollen packed into the outdoor coil make it worse by trapping heat the unit is trying to shed.
When we repair an AC in Portland, we look past the failed part. We check capacitor ratings, contactor wear, coil condition, and refrigerant charge so the system is ready for the next heat wave, not only the current one. If the equipment is undersized for your home, we tell you that too.
If your AC is 12 to 15 years old, still uses R-22 refrigerant, or needs a repair that costs more than half the price of a new system, replacement may make more sense. The technician will explain both options and let you decide. If you choose to replace it, our AC replacement service explains how that works, and new central AC systems start at $6,995 installed.
After a repair, a yearly tune-up under an HVAC maintenance plan can catch worn parts before the next summer. If you also heat with a furnace, our furnace repair service uses the same $189 diagnostic and written quote.
Some AC problems are safety issues. Others can wait a day or two. Start with the safe checks below, then use the lists to decide how soon to call.
Don't open the outdoor unit or touch wiring, capacitors, refrigerant lines, or fan blades. A capacitor can hold a dangerous charge even with the power off. You can still watch for the warning signs of a bad capacitor, such as a hum with no start.
A customer of our Milwaukie office had an air conditioner stop on one of the hottest days of the summer. We sent a technician out that day.
"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 starts with a $189 diagnostic, and that fee is applied to the repair if you go ahead. The technician then quotes the repair in writing before any work starts, so you approve the exact price first. We charge no overtime, and we are licensed in Oregon under CCB #187834.
Consider replacing it if your AC is over 12-15 years old, uses R-22 refrigerant, or needs a repair that costs more than 50% of a new system. The technician gives you an honest repair-or-replace recommendation, and we confirm current Energy Trust offers in your estimate.
Most AC repairs are completed the same day. The diagnostic takes 30-60 minutes. Simple repairs, such as a capacitor or fan motor, take 30 minutes to 2 hours. Major repairs, such as a coil or compressor replacement, take 4-8 hours and may need a parts order.
Most repairs include a 1-year parts warranty, and extended warranties are available. Carrier, Bryant, and Lennox parts we install also carry their own manufacturer warranties. We explain the coverage before work starts.
Yes. Emergency requests are taken 24/7 and dispatched when a technician is available. During Portland heat waves we prioritize no-cooling calls, refrigerant leaks, and electrical problems, and our trucks carry common parts.
First, make sure the thermostat is set to Cool and the air filter is clean. If both are fine, the common causes include low refrigerant from a leak, a compressor problem, a frozen indoor coil, or a blocked outdoor unit. We diagnose and repair these the same day in most cases, before the compressor is damaged.
Yes. We repair all major brands, including Carrier, Bryant, Lennox, Trane, Rheem, and Ruud. Our NATE-certified technicians work on central AC, heat pumps, and ductless mini-splits.
Uneven cooling usually comes from a dirty air filter, low refrigerant, a thermostat problem, or leaky or undersized ducts. We find the cause, balance the airflow, and repair duct leaks so every room cools evenly.

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
