"Company was called because the error codes on the system indicated that the pressure switch was in a stuck open position. Prior to calling, I replaced the pressure switch but still got the same error codes. The technician checked out the entire system, cleaned the vacuum lines, and finally got the system working. Problem appears to be intermittent and non-reproducible. Technician went back to shop, talked to other technicians to get their opinions and returned the next day. At that time, he stated that he had run all of the tests that any of them knew of and there was nothing else he could do other than start changing out parts that would cost a lot more and might not solve the problem. On the day of his return, he also changed out the condensation pump that was failing. I feel that I got the best service possible for the price and appreciated his not trying to get more money from me by changing additional parts.

"THESE ARE THE FOLKS TO HIRE! When I contacted Ares Comfort Systems, Shawn came out right away. We talked about what I wanted and what my budget was. We have solar and I wanted to switch from natural gas heating to an electric heat pump with a gas furnace to back it up in case of an extreme and prolonged cold winter storm. Chris offered four different options for me from a top of the line electric heat pump and blower, to a simple natural gas replacement furnace (mine had just died after 25 years). I also got four different estimates from other venders including one from a friend who does this in retirement. Ares was by far and away the best price for all four different options. In fact my friend who also made a bid strongly suggested I go with Ares, and I did saving me about $3000 or about 25% (it is true!) under the other venders. Chris, Kirt, and their crew came out and performed the install in a single day. The install was not simple but they did a fantastic job with a clean install. The equipment was not the highest priced (the Cadillac of heat pumps) but it was a close second and will likely outlive me while saving me money and helping the environment at the same time. Ares gave me a bid and assured me if there were any surprises they would cover the extra cost. Who does that anymore?!? If ever I need heating or cooling equipment or work, I will absolutely go with Ares Comfort Systems. I will recommend them to friends and family alike. Do yourself a favor and call them for your heating or AC needs."

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.
