"I conducted a lot of research prior to hiring Air Factor, and obtained bids from 6 different contractors. Air Factor was the ONLY company to calculate the size of my home to determine the appropriate size of the AC unit to properly cool my home. They were VERY thorough on the initial visit - spending 2 hours with me. Tim had a great presentation put together, including reviews from customers, insurance information, and BBB ratings/reviews (ZERO complaints by the way). The detailed information he provided built trust in the contractor. I would use them again in a heartbeat, and will definitely recommend them to my friends and family."

"Fabulous service. The employee who checked our air conditioner was personable and knowledgeable. He replaced a small part, cleaned both of our air conditioners and now the noise that one of them was making is gone. We were pleasantly surprised by his friendly manner and we felt him to be extremely trustworthy which is a rarity these days."

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.
