"Purchase and installation of heat pump went very well. David came the very next morning after my call for help. He gave me the estimate on the best pump suitable for my needs plus all the equipment and labor to complete the job. The day of installation everyone arrived early. Each person had their specific part and each went right to work. The whole system was completed the same day. Everything was cleaned up and the old unit hauled away. Nick came to do the inspection after a week to see if all was running well. All were so friendly and professional. They did a great job. I have had a maintenance contract with Quality Air for several years and all the guys who come to my home have been friendly and professional."

"Tim is the best service technician! He was out today today for a maintenance and service call. He is very experienced and clearly explained what was needed and to recap at the end of the visit! I first started working Sheer Comfort in 2023 when they installed a new AC & Gas furnace for my home. I obtained 5 quotes from highly rated companies before deciding which company to engage. I worked with Travis Shearer (owner) on deciding which options were best for my home and I was impressed with his knowledge, fair pricing and ease to work with. The project was well supervised by Carl and installed by David & Eli......they were all great to work with. Tonya in the office was excellent in keeping me posted on timelines and managing the coordination for permitting and coordinating with the 3 sub-contractors needed for running gas lines and electrical to connect my new furnace and for a plumber to make changes to my water heater from my old gas forced air system. Sheer Comfort is the best!"

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.
