"Our air conditioner is getting close to the age where it needs to be replaced, so it’s starting have problems. Right now Portland Area is enduring a heat wave (~90F), so of course, it broke down. John helped me last year so I called him. He responded ASAP. He quickly found the problem and fixed it. Now my dog and I are sitting in a cool house. John knows his stuff, is quite friendly, and very professional."

"They come once a year for the checkup on the furnace and air conditioning and make sure everything is set for Winter. 
I have had them every year for years. It has always been good!  
The air conditioner is still working and the furnace is still working, so I guess it is pretty good!"

"They did a great job. From the estimate visit to explaining the costs and work and options to choose from. Also, they were quick to get on the job. They were very punctual and worked straight through 2 days to get the air conditioner installed. It required extra work because they needed to rearrange the furnace, all of which was explained to me in the estimate. The final price was exactly what they quoted me and there were no surprises. The technicians, Matt and Hudson were friendly and professional and hard working. I will be calling them to do the annual maintenance. So, thank you Angi for helping me find them."

"Beyond excellent. Found out our shops HVAC was out, mind you it’s already 2 pm and pushing 90 degrees outside. Contacted Revival Energy and within an hour, a repair man was addressing the issue. He was able to fix the problem with the upmost kindness and professionalism, all while maintaining social distancing. Definitely saved the day for the shop. 11/10 would recommend."

"Tom and his crew were fabulous. The most important thing was I completely trust him from day one. He was so honest and so quick. I called him he came out that day and within two days I had a complete new heat pump, air handler etc... I have had some medical issues and they never embarrassed me about the lack of repair in my home. What a great crew!!!"

"Chase, our Elevate service technician discovered a dangerous DIY install on the furnace. He explained everything in detail, repaired the damaged gas line, and prepared the entire air/heat system for winter. Aside from potentially saving our lives, he was kind enough to let me follow him around asking questions so I could learn how it all works. Thank you Chase!"

"It went extremely well. Punctuality was perfect. Paying attention to details was perfect. Knowledge and professionalism were perfect. The price was competitive. We interviewed 5 different providers. Ultimately, Columbia seemed to stand out best. We tried it, and we were quite happy with the choice. The service cost was for two independent air conditioner systems ( we have a large, long house), and one new furnace."

"Home Pro Heating and Air did an excellent job fixing my A/C. From the moment I called, they were professional, responsive, and straightforward. The technician arrived on time, diagnosed the issue quickly, and explained everything in a way I could understand. The repair was done efficiently, and my air conditioning has been running perfectly ever since. Their pricing was fair, and the level of service was outstanding. It’s rare to find a company that’s both honest and highly skilled, but Home Pro proved to be both. I’m extremely satisfied and would absolutely recommend them to anyone needing HVAC work."

FAQs for air conditioning projects in Portland, OR

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
