"We found VIP HVAC using HomeAdvisor. Based on the high review feedback number we hired them to replace our furnace and the AC unit. We ran out of heat on a cold day in February. The contractor came on a very short notice. He was a subject matter expert on heating/cooling and explained all the options. He gave us a quote that was unbeatable. He also rescheduled multiple times to accommodate our schedule. On the appointed day, they came right on time even though roads were closed due to slippery conditions. Our heat furnace and AC were replaced. As a bonus he changed the fixture on the furnace unit to install a new compensating pump and a air filter enclosure that was easy to access at no cost. I will highly recommend them."

"QNC HVAC was extremely responsive. The guys came over within an hour of me calling them. They had the proper tools and knowledge of the work required. They executed the work quickly and efficiently and offered additional service which at this time we did not order. The blockage was found removed and the guys cleaned up the area and left on great terms. I would call QNC again if I had a plumbing issue."
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.
