"I highly recommend this company! They were able to come out the next day to service our furnace. They were quick, responsive, friendly, and reasonably priced. They charged half what their competitor had quoted. I will absolutely be using them again in the spring to service our AC."

"Mark called me the same day I made the request for quotes/bids. He was on time for the in-home evaluation and provided a detailed estimate/proposal within a few hours. Mark is a straight shooter and gave me several options along with explanations as to what was gained or lost at the different price points. He was also very kind regarding other estimates and helping me to verify I was comparing apples to apples. The job was scheduled sooner than I anticipated, which was nice. His crew was on time and began removal before Mark arrived on sight to work with them and supervise. His workers were very professional and mindful of my overly curious cat that seeks to escape at any opportunity. The entire job took a day to complete from beginning to end and they hauled away the old equipment and scrap. The AC now blows nice and cold for the first time in about 10 years. After years of window A/C units, I had forgotten how great (and quiet) a properly installed and functioning central air system is. I highly recommend Mark and his business Air Control Systems for any HVAC work you may have. They have earned my business for as long as I live in this area. Thanks guys- Great job!"

"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."
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.
