"Very professional. They did an annual service check on my furnace. While doing so, they found that my filter was wrong and could have caused major damage to the furnace. They were able to find me the correct filter in a timely manner. I'll be calling them whenever something is wrong or I need another furnace cleaning/check."

"Our residential AC is in a converted bus. We are new to the area, and first called several other companies who could not work on it (because they were RV repair technicians and not HVAC certified) or would not work on it (because most HVAC certified technicians were not work on motorhomes). We are so grateful that Pacific air was willing and able to work on our unit. We are fully satisfied with the work they did, as well as the very reasonable fee they charged."

"Habib is seriously the most thorough professional we have ever had! He expertly explained the new AC/furnace system to us so we knew precisely how the system worked, before he installed anything. He was so considerate and enthusiastic and he loves helping his customers. Our A/C unit worked so well and I know our brand new furnace will be great this winter. If I could give him 10 stars I would because he was so knowledgeable and conscientious!"

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.
