"We called several HVAC companies for our ductless mini split, but Aviator was the only one that responded quickly. They fixed the issue the next day and saved us from replacing the whole system. Excellent service!"

"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!"

"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."

"After an energy audit which was very informative and helpful, we moved ahead with attic insulation/sealing that we found let our home internal temperatures to raise by 2 degrees. The manual furnace damper allowed us to adjust the flow of the furnace output to equalize the temps in each area of the home. Our house had very defined cold spots, and now the rooms are able to be heated to the same temp throughout the home, even with the recent cold spell. We are very grateful for their expertise and their staff and workers were very responsive."

"WOWWW! Above & beyond service, courteous & knowledgeable technician, and fair pricing... what more could you want?! I contacted Air Control Systems via Angie's List and (literally) within minutes received a phone call. They were able to send a technician out that same day (rare in todays service industry!) at no extra charge. Nathan was very personable yet prompt. He fixed the issue, while also checking everything else out to ensure peak performance moving forward. The cost was very fair, and I will not be using ANY other company for HVAC issues in the future! Outstanding!"

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.
