"We scheduled a 4 pm appointment. By 4:45, no one showed up or called to confirm their whereabouts. I had to call Metro Air and ask what was going on. The secretary said she will dispatch a technician to my house. The technician did not arrive until 5:30. He was kind and was able to fix the capacitor, which was causing the issue. About a week later, their office followed up. I told the lady that the a/c was on, but now there was another sound coming from the system. The secretary indicated that the technician would call me that day to discuss and set up a follow up visit to address the issue. No one ever called."

"He works on Sundays for no extra charge. When I did the request to be contacted by three companies, he called within 30 minutes and was at my house two hours later. Haven't heard from the other two. Very professional. The charge was $300 to unplug lines in air conditioning units (2) and install safety valves that will turn off A/C if leaks occur. I called because my house smelled like mothballs!"

FAQs for air conditioning projects in Lancaster, TX

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.
