"5-Stars for Shawn at Precision Air! We were looking for a dependable and experienced HVAC technician when it came time to replace our furnace and add AC. We discovered Shawn at Precision Air and couldn't be happier with our choice. Shawn was incredibly professional and responsive from the start. He listened to our requirements and explained all of our choices. He also provided us with a detailed and reasonable quotation. Shawn got right to work on the day of the installation and arrived on time. He took great care with his work and made sure everything was done correctly. He also took the time to instruct us on how to use our new system. Even after the installation, Shawn's follow-up was excellent.

For all of your HVAC requirements, we strongly suggest Shawn at Precision Air. He is a real professional who is proud of his work and who we will surely hire again in the future."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

Now, our bathroom feels like a spa every time we step in. I appreciate the quality and attention to detail. These folks definitely know what they?re doing!"

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.
