"Jack and team came out on a less than 1 day notice as they were wrapping up the day. 5 other companies told me I had to wait until the morning. Jack explained each troubleshooting step, found the root cause quickly. Repaired on the spot and charged a very reasonable price. I will definitely hire again. As a matter of fact, I signed up for the maintenance program."

"CM Walter Heat and Air did a fantastic job on my older AC unit. We had another company come out first. They couldn’t get the parts in and installed for another three days and the quote seemed high so I called Martin and he came out the same day. Diagnosed the problem and had me back up in running in minutes. He also saved me a ton of money. After it was all said and done he saved me over 800 dollars! I highly recommend this company to anyone in need of AC work!"

"New heat + ac unit installed. Very satisfied. We recommend him."
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.
