"One Hour Heating & Conditioning was prompt arriving at the scheduled appointment time. My wife and I also appreciated receiving a message that the techs were on their way. Our techs Kyle and Jacob were friendly, professional, and knowledgeable. Arguably one of the most thorough annual checkups I have had since being in the home for 7 years and using some other services in the past. While both furnaces are well beyond their expected life, neither tried to "oversell" me and offered objective pros/cons to some repair options vs. replacement. I would highly recommend One Hour Heating & Conditioning."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"Nice young man did his work and left my place clean. When he finish the job."
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.
