"I highly recommend Comfort Central. Owner Kevin Schumann and his co-workers, Jay and Thomas, did an outstanding job installing the new HVAC system at our house. Over a four-day period, they set up in our crawl space a furnace/AC unit, a new plenum box, pipes for venting, and a dehumidifier with its own elaborate duct and water-removal system that will help keep our huge crawl space dry. They also put in a new heat pump in the backyard and a thermostat in the house. I was so impressed by the people and the work they did. Kevin and Jay are remarkably knowledgeable and experienced when it comes to HVAC issues. Thomas did a very good job with the aspects of the project that he handled. Every installation presents its own challenges, and one of the best things about Kevin and Jay is their ability to improvise as the project moves along. They considered different options when deciding on the size of the new system, where vents should go, how the duct system should be repaired and improved, the placement and venting of the dehumidifier, and many other things. They always kept the code requirements in mind. They were on time, friendly, communicative, and always considerate about how their work affected us while we were in the house. Kevin, Jay, and Thomas were also terrific when it came to answering my many questions. Kevin’s wife Laurie, who manages the office, responded quickly to my e-mails and helped with scheduling. HVAC projects can be expensive and complicated, and we wanted the right company to handle ours. We learned about Comfort Central from our home health specialist who had worked with Kevin in the past and had received very positive comments about his team from customers. I can recommend Kevin and the Comfort Central crew without reservation."

"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!"

"I had a major remodeling project and got help from their sales manager / designer who was the best! Too bad he left the company. The building manager who coordinated my deck build left the company after just a week. The electrician is wonderful & so is their primary tile subcontractor, but everyone else you need to watch closely. Surface Bella is very expensive and I doubt I got my money's worth, but at least they didn't run out on the job. They also tend to cut corners."

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.
