"Roy came out and gave me an estimate which I thought was reasonable. He explained what he would do and what he would throw in. I got a new Trane 95% efficiency 100000 BTU furnace and 3 ton a/c unit, a new thermostat, and a small pump to pump the water from the AC and heater to my washer drain. He had to make some changes to the intake duct including making a new spot with a door for the filter, and capped the flue to the chimney since the new furnaces are vented differently. I also got a new 50 gallon water heater. He threw in a 10 year parts and labor warranty on the HVAC system provided I do twice a year maintenance, and threw in the first 2 years of maintenance for free. It was a three day install. The first day they installed the water heater and removed the old water heater and HVAC. He also hauled off an old dishwasher I had replaced over the weekend. The next two days was installing the new HVAC. We decided on a new spot for the outside unit which was better than where the old one was. Better air circulation and more secure. Roy always kept me informed as to what they were doing and how long he expected it to take. Roy and his crew were very courteous and left my basement cleaner and in better shape than when they started. I am very happy with the work he did for me and I'm very satisfied with the new equipment and highly recommend him."

"My heating/cooling unit was acting up and wouldn’t stop running, I was familiar with the company by seeing them at other homes in my neighborhood so I called and spoke with Ashley M. (They have 2 Ashley’s there) and she was able to get a technician scheduled to my home the next day for my repair. I was happy with the ease of the experience and the friendly demeanor that now I have a annual maintenance plan with them and when they come for my check ups, my dogs absolutely love them just like family and they love them right back."

"Varsity Zone hit a home run with their service. From my initial call to discuss my heating issue to having Jesse come out and explain everything, they were outstanding. Jesse diagnosed the issue and was able to provide a few recommendations and solved the heating problem. I highly recommend and will only be using Varsity Zone from now on."

"Corey came out at 8 PM on a Friday night to fix our furnace. Was very professional and efficient."
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.
