The team was extremely polite and professional and respectful of my home. Price quoted was way better that I was expecting. If you are looking for a great team of professionals. Look no further. Thank you so much and Happy New Year! - Jan L."

"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."

"The technician was very knowledgeable and did a great job. It wasn't cheap. But he got the job done and did it well, I think. We'll see how it holds up with time."

"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."

"Tech explained everything (am ex-engineer) to my satisfaction. I have 2 20+ year old AC systems running just fine thanks to the 10 years of maintenance I've had from Sundance. Well worth the price."

"Bryan was amazing! He showed up right on time and made two trips outside of Salem to find parts to get my air conditioner running during a heat wave. Absolutely recommend!"
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.
