"First of all, Sam called me 20 seconds after I requested a quote. He is very knowledgeable in his trade and a very fairly priced businessman. We scheduled an appointment in which both of our schedules allowed, he was on time, and handled our issue with our air conditioning unit in a very short time. Easy online payment accepted and most importantly, our unit works again. I highly recommend this business for your HVAC needs."

From the moment I called, I felt like I was in good hands — they scheduled me quickly, showed up on time, and took the time to explain exactly what was wrong with my AC unit. The technician was friendly, professional, and worked efficiently to get my system up and running again, which made a huge difference in this Clovis heat! I really appreciated their honesty and fair pricing, and I wouldn’t hesitate to call them again or recommend them to friends needing air conditioning repair or HVAC services."

"Great Heating and Air company! Highly recommend, great prices and quality work"
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.
