"We were completely impressed by the owner Jason Nikkel when he came out to assess the situation with our old HVAC system. We had several problems including insufficient air flow to a newly enclosed porch and problematic duct work. He advised a new system and presented options at various price points, after a careful analysis of our home, attic and crawlspace. While we could probably have gotten this all done for less money, we are completely satisfied with the results. Jason and all the workers were nice, professional and competent. I would definitely recommend this company to anyone needed an HVAC replacement."

"Devin Andrew did an absolute fantastic job converting our microwave from recirculating to outdoor exhaust. Devin was on-time to our home and his knowledge was spot on. He completed the job in just a couple of hours, and cleaned up as though he was never here. Thanks, Devin Pat V"

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.
