"I hired Sanchez Heating and Cooling a year ago. I am 110% satisfied with my heat and my air! Everything works perfectly and they also redid the duct work! It looks and works great. I had a question and called Johnny and he was here to fix it, immediately. They are quick, neat and professional. The price was great I can't recommend them enough."

Customers say: Quick response
"They performed a fast, clean installation of a new system and relocated it to a more favorable location. I had them delete the unit in the attic because of prior water damage from a leaking unit. They were able to plumb into the old venting. The house is now quieter and cooler. Everything is working great, and we are completely satisfied with the work that they performed. Very efficient at their job and did an excellent job of cleaning up."

We show up on time and get the job done right the first time
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.
