"We had recently purchased a home and had reason to be believe it had been some time since the HVAC was serviced. Aire Serv came out and performed a cleaning and inspection of the system. The technician was punctual and polite. He did a good job and fixed a minor leak we had in the condensation line.
They offered some recommendations for improvements, but did not try to upsell us on anything.
We will be using Aire Serv again.

"Ronnie and his crew were outstanding! They installed the split system air conditioning units in five of our rooms and it had been life changing. Our electricity bill has been halved and the units do an incredible job of cooling the entire house. Ronnie had to work around another construction crew s timeline and he was patient and accommodating. His price quote was one third of other air conditioning systems and I am so happy we called him. He is the best!"

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.
