"My solar panel system had electrical problems and the original installer has gone out of business. Solar Panels were not listed specifically about so I chose something close. The Allset technician worked with the manufacturer, and made the repairs. Everything is working well now."

"Company was called because the error codes on the system indicated that the pressure switch was in a stuck open position.  Prior to calling, I replaced the pressure switch but still got the same error codes.  The technician checked out the entire system, cleaned the vacuum lines, and finally got the system working.  Problem appears to be intermittent and non-reproducible.  Technician went back to shop, talked to other technicians to get their opinions and returned the next day.  At that time, he stated that he had run all of the tests that any of them knew of and there was nothing else he could do other than start changing out parts that would cost a lot more and might not solve the problem.  On the day of his return, he also changed out the condensation pump that was failing.  I feel that I got the best service possible for the price and appreciated his not trying to get more money from me by changing additional parts.

"Carlos and Rigo are very professional and knowledgeable. I had a terrible smell in my home and called these guys to help. They quickly diagnosed the problem as having a cracked heat exchanger. They recommended replacing the furnace as repair would be around the same cost plus a new one comes with a warranty. They sent me a quote which I approved and they replaced the unit promptly. The new one they put in was more efficient than the old one and they also replaced the thermostat and fresh air damper unit. I learned so much about the process from them. They are attentive to answering your questions. They are very respectful of property and keep you informed throughout the process what they are doing. I am very impressed with their work. I will be using them for future jobs and highly recommend that you give them a try yourself!"

FAQs for air conditioning projects in Walla Walla, WA

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.
