"I found Cool Air via web search for AC Tune Up. They were offering a $39 system check which worked for me. Setting the appointment was very easy and straight forward. Jerry came out the next day and called 30 minutes prior to arriving. He was gloved masked and had booties covering his shoes before entering my home. He was very knowledgeable and made a number of no pressure recommendations and system additions that I didn't feel compelled to have installed. Jerry's approach was more as a consultant vs service person. I like this and would use Cool Air in the future."

"Had to call TE for an emergency fix on what another company screwed up with our air conditioner. I was booked and had someone at my home within two hours. Nemo M. our technician was incredible!! Solved the problem in no time--and could not have been friendlier. He was also extremely patient in showing and explaining everything he was doing. I will never use anyone else here for any HVAC again!!!"

"I did a quote on Angie needing help with my newly installed HVAC system in my recently purchased home. Kevin was the first person to call me, I explained what was going on he asked a series of questions and eventually referred me to the installer of the system. Informing me there should be a minimum one year installers warranty, to figure out whom installed it and to get them back out as to not void my manufacture warranty by allowing someone else work on the system. I received and used information from my broker and the same day 4/24/26 called the original installer and they are coming today 4/28/26 to fix this brand new system. The Peoples Champ Heating & Air, will be my go to experts once this courtesy one year warranty is up for sure. Thanks Kevin. For being a honest decent person, caring more about your craft and building relationships then making a Buck."

"Jason Erwin was the best sales advisor I have worked with. He knows alot about AC systems and answered all of my question prior to my purchase.The install crew was very efficient installing a complete AC system. They wasted no time while they were at my home and answered all of my questions. They also made sure that they cleaned up after they were finished."
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.
