"Anthony was terrific! He got the job done in a few hours and did the estimate and the job all in one day. PES&G left us without central air for 10 days! Thank you Home Advisor for sending us Celestial Air and their employees. Anthony was tops!"

"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."

"They definitely earned this 5 ⭐️⭐️⭐️⭐️⭐️ review!! I can't say enough good things about VIP HVAC, they truly went above and beyond! Hector, the owner, came out with two of his crew members the day before the 4th of July to replace both my AC and furnace. They arrived right at 8am and worked nonstop until 6:30pm to make sure everything was done perfectly. Throughout the job, they found a few unexpected issues, but Hector and his team kept me informed the entire time and handled everything with professionalism and care. I was so impressed by their hard work, attention to detail, and clear communication. If you’re looking for a trustworthy and dedicated HVAC company, I highly recommend VIP HVAC. Hector and his crew are the real deal!"

"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."

"After getting four or five quotes, from recommendations and Angie's list, we chose Dawson Mechanical to install two new furnaces. The crew arrived on time and got the first furnace working by the end of the first day and the house warmed up. The second furnace was completed the second day. However, the crew forgot to relight the hot water heater. Dave came back that evening to take care of this small issue. We would definately use this company again."

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.
