"I cannot recommend Perfect Air Solutions enough. John came to my house on a Saturday afternoon to take a look at my dead condenser and by Monday evening, we were pumping cold air with a brand new condenser and coil. The price was more than reasonable and far better than the estimates I got from competitors (and with higher quality equipment!). John's team worked late into the evening on Monday to do the install and stayed even later to show my wife how the program the thermostat through her phone. There are many other companies out there that I've spoke to and none compare to Perfect Air Solutions value, quality, and responsiveness. Do not use anyone else!!"

"Hired Joseph to replace my central air conditioning condenser and coil, as well as relocate a handful of vents. I'm happy with the results, but also Joseph was great to deal with even though I wasn't really an ideal customer. He was very flexible, communicative, trustworthy, and super easy to work with. He's also a smart and creative guy just in general. Would recommend."

"Sam Capitals was a life saver! We had to replace our condenser and air handler after 25 years and Sam was able to schedule a service call immediately and the units were installed 2 days later. Sam is very knowledgeable and professional and very easy to work with. The process was stress free and the cost was less expensive than his competitors. I highly recommend Comfort Heating and Cooling. You won t be sorry! P. Schwartz 5/24/2019"

"I was able to get a same-day appointment, and Abraham showed up right on time. He took a look at the system and confirmed that the furnace was running as expected, and he didn’t find evidence of a cracked heat exchanger. I was hoping for a definitive answer as to why the air wasn’t flowing out of several of my vents, but he was only able to confirm that it wasn’t due to the furnace itself. I may have clogged or separated ductwork behind the walls, but he wasn’t able to diagnose/confirm. At least I know the furnace itself isn’t the source."

"Now I feel safe turning on the unit after the ducts and the sealing was done and cleaning my air condition and my dryer and bath room filter and my condenser outside and putting a new cover for the vent outside of my dryer. After seeing the pictures it was worth the price."

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.
