"Brian installed my new Trane AC unit and air handler and did an outstanding first class job. Pre-sale, Brian was very knowledgeable explaining all my options, and worked within my budget. He made recommendations, ordered and installed the new unit in less then a week. The installation went great and we had air in a few hours. The follow up post installation was prompt and professional. I highly recommend Clear All for service and new installations."

"Scheduling was right on point. System was installed right after Christmas. Prep process was thorough. Extremely responsive when we switched over to A/C and performance wasn’t as expected. Was a factory setting issue. Very communicative amongst their team and with us. Great follow through. Proactive annual maintenance scheduling and thorough in their system review. Would definitely use them again."

FAQs for air conditioning projects in Suncook, NH

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.
