"Matt was prompt and professional and the work he performed was impeccable. We had wall-mounted AC/Heating units installed in a traditional seaside cottage, and he was meticulous about finding non-intrusive ways to run plumbing/electric. He even upgraded to stainless steel hardware considering our corrosive sea air environment. I will recommend him again and again."

"Extremely friendly service. Prompt and professional. It was a little more expensive than I thought it would be to swap out a light/exhaust fan, but the work was excellent and I would hire again in the future."

"I have been looking for a handyman to initially remove 4 air conditioners and put them away. I found Bill today. He came later in the day and did the job quickly and it's a big relief to have them removed before the chilly weather starts. He kindly removed my frig grille so I could clean under the frig. I am so pleased and grateful for his help. I'll be calling him to do some small jobs on my list. Thank you, Bill"

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.
