"This was my second quote and this company is amazing. Quickly identified the issue, changed the motor, provided a filter and made sure everything was working on one trip within a few hours. The previous company (Air Pros, LLC) said it was unfixable and tried to sell me a new unit over $6k which was a huge scam. Don't go to those guys, work with this family owned honest business. Keep in mind HVAC repairs in many cases are not cheap, I own 3 houses and have paid several hundred or more when an HVAC is old and need repairs."

"Hottest day of the year so far, and the guys were in a sweltering attic half the day. The other half of the day they were trying to decide how to hoist the LARGE air-conditioning unit onto a ledge without destroying the landscaping. They had to bring in a 4th guy and a long, wide plank. They put that unit on the plank and three pushed it up the plank while the fourth helped position it. The men were appreciative of the cold watermelon I gave them and I welcomed them to help themselves to jug of cold water in the fridge. They had a f ull day's work on day one, then on day two, one man returned to finish the ductwork and the installation of the vent.

"Great. Jerry Cobb came by to reprogram the thermostat for us. We were not able to figure out how to get it the way we wanted and Jerry took care of it for us. Cool Air replaced our entire HVAC system about 2 years ago. We were happy with the job and will be having them add a humidifier to the system soon."

"I highly recommend this business. The technician, Pierer, and his colleague were true professionals and incredibly courteous. Even though I was their last appointment of the night, they went above and beyond to source a replacement part that wasn't stocked on their truck. I truly appreciate their dedication to getting our HVAC unit running late in the evening. Thanks to them, my family was able to sleep comfortably with the heat restored."
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.
