"My AC unit stopped working during particularly hot stretch. Tom from 412 Emergency Electricians responded very quickly, set out pricing expectations over the phone, asked when i needed the work done and showed up the same day. All work was completed quickly, expertly, and prices were explained. Of course emergency service is expectedly more expensive but having a professional complete the work and provide a guarantee is worth paying for. Tom went so far as to teach me a little preventative maintenance which may save me more money in the long run."

"I had a fifty year old furnace that provided its last breath on the coldest day of the year and John the owner saw to it that I was financed and gave me a very good price. It was flawlessly installed the next day by his courteous staff and they hauled away the old furnace too. Great job! Thank you."

I have 8+ years experience in the heating and air conditioning field. I’m very mechanically inclined, therefore I’m quite useful to do just about anything. I’ve done everything from general around the house stuff to full scale renovation work. I would be my pleasure to do any work for you!
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.
