"I am so happy I chose company Extra Air to replace our air conditioning unit. Art was incredibly professional and trustworthy. Art and his team were all very hard workers and did not stop until the job was done which was greatly appreciated since it was so hot outside. Art and his team made sure to take all precautionary measures to make sure they didnâ t make a mess and made sure to clean up after themselves; they were all very respectful and considerate of us and our home. The new unit is working great and we are really enjoying the cool air. Art truly went above and beyond, and I am so grateful. I will 100% chose Art for any air conditioning work in the future and highly recommend him to anyone in the area who is looking for an honest, knowledgeable, and professional company."

"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"My central A/C return in the attic had a clog and Challenger, which is the best Heating and Air Conditioning Corporation in the Universe, came over a day early and so fast and fixed the clog in the A/C return right away. I love this company. My wife, Debra Jean keeps saying she's a Challenger girl for life and she means it. And the costs are so reasonable and I can't thank you enough for coming over a day early to literally save our lives. If you are in the area where Challenger works, look no further, call them. They are wonderful beyond belief."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

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.
