"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 thorough comfort assessment with blower door test and infrared analysis throughout the house and recommended changes - some of which we could do ourselves. They also reviewed our heat pump and determined that it was way overized. So we wish we gone to Revival before we installed our new heat pump, and recommend others do the same."

"Dave from Columbia came to my place in Portland from Scappoose on a same-day appt, for what I thought was a dead furnace. (I had tons of smoke flow into the home after furnace turned on.) Rather than just presuming the furnace was dead or even the problem, Dave poked around. He discovered the smoke was from the fireplace/chimey and the furnace turning on had pulled air from the chimney, reignited a smoldering log, and then filled the house with smoke. The problem was with the chimney all along, but Dave/Columbia did not charge me anything for the trip to Portland---or for diagnosing the problem---even when I called later to offer. Great service, great customer relations, great knowledge of how air moves through homes."

"When our air-conditioning unit stopped working during a heatwave, Jason came to our aid very quickly. The unit was over 20 years old and we knew it was on its last legs, though, it had miraculously to stay working since Jason fixed it 7 years prior (and saved our wedding!). As we expected, we needed a new unit and decided to also replace the furnace. Jason was able to schedule the replacements within a quick time frame, and he worked thoroughly and diligently to ensure that our new units were installed with the utmost care. He was very clean and conscientious, and we found him to be both honest and personable. We will continue to use Jason for all of our HVAC needs and highly recommend him to others."

"This company was wonderful. They wee very conscience about keeping my house clean, the time it took, and they didn't charge me the three hours it took for them to search for the leak. They repaired everything and proved to be very honest with me. I would recommend them."
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.
