"One of our 12-year-old heat pumps stopped working a week ago. Then the other went out 3 days later, leaving us with no air conditioning in 90 degree weather. I called Montgomery Heating and A/C on Wednesday, and was told they couldn't get here until Monday. But I understand, given that this is their busiest season.
As promised, John and his son arrived Monday afternoon, after phoning to say they were on the way. They diagnosed the problem, replaced the capacitors, and the systems began working immediately. Very fast, very professional. And a big relief to know that we only needed affordable parts, not two brand new systems. Thanks, Montgomery Heating. I highly recommend.

"Mr. Ferrell worked with my husband over the phone to fix the problem. It was surprisingly fast and stress-free. To have the work done remotely in less than an hour was wonderful."
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.
