"We called Eli when our old humidifier started leaking. He came out that day to take a look and recommended a new unit to replace it since it was 22 years old. He returned a few days later and installed the Aprilaire unit and it works like a dream. I would recommend Eli for all of your heating and air repairs."

"We tend to try and have the heating inspection and the air conditioning every year. We don't always quite accomplish that and we've had other people do it but I thought their prices were fair. They were prompt in getting here and answered whatever questions I had. It took them about 2 hours to do the work."

"Computer had been acting up for a while but I kept putting off getting it fixed. After reading all the great reviews, I decided to give N.A.T.S. a call. So glad I did. Jim was able to resolve all my problems remotely - no drop off or pick up necessary - so convenient! I feel like I have a brand new computer, it runs so well and FAST too. I couldn't be happier and wouldn't hesitate to use his services again. My only regret is that I didn't call him sooner.

"Great company to hire for heating and cooling service issues. Quick response to needed service."
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.
