"Kevin was great. Our Central Air System died during a Heat Wave . When other companies told us they couldnâ t give us an appointment for two weeks, Kevin came the next morning and on a Holiday weekend. He was quick and reasonably priced. We would highly recommend Kevin Russo to anyone looking."

"I found Comfort Air online and reached out to install central AC in my mother's condo. Patrick got back to me promptly, was very receptive in answering all of my mother's questions, and was able to start job within a couple of weeks from first call. The job took two days total, and my mother was impressed from start to finish! I highly recommend Comfort Air."

"I wish I could give more than 5 stars to Moulton Mechanical Services. In this day and age of spotty service, Jarod is like a throwback to when excellent service was valued. He is always responsive, checks in frequently and goes above and beyond what is expected from a vendor. When we had a major problem resulting in needing a new heating system, he even lent us some of his own portable heaters to get us through and checked on us frequently. He also advised us that the damage caused by our faulty heater should be covered by our insurance which we would never even have considered. He checks in frequently and answers all calls and texts promptly. I cannot think of a situation where I have had better service, ever. I highly recommend Moulton Mechanical Services for both heating and air conditioning. He also advises on the most cost effective systems and solutions. Darlene and Jim Underhill"

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.
