"Just have to get used to the new furnace. "Ben" was nice enough to have the old air condition system removed without replacement, at my request. Customer service is very good."

"I was referred to Columbia Heating and Cooling through NW Natural. My furnace randomly stopped working (later found out it was because of a squirrel...) during some of the coldest nights we've had so far this winter. The tech showed up ahead of the scheduled time and was able to fix my furnace within 30 minutes. No complaints, and glad to have heat again."

Customers say: Quick response
"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!!!"

"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."

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.
