"We were switching over from oil to propane heat. It was a pleasant experience from the time we first met Jason who was very knowledgeable and a joy to talk to. The installers were very professional and did a great job. Aire Serve worked seamlessly with Curtis oil and job was completed in 1 day. We are warm happy campers and would definitely recommend Aire Serve and Curtis Oil & Propane."

"Jim responded promptly to my order placed on Angie's List for the Remote Computer Tune Up & Repair Deal. He cleaned up the computer remotely, which was running very slowly, and required frequent re-boots. Computer is running much faster now. Great service. Would highly recommend.

"I would highly recommend Jomac Mechanical for any of your furnace, duct work, or central air needs! He is reliable, responsible, very conscientious, and does an excellent job! He installed my new central air conditioner on the hottest day of this summer and on the west side of the house. Joe made certain he had cleaned up both the yard and the basement where he needed to run new lines. After the installation I noticed a noise coming from the furnace.I called Joe and he came right out and found the problem at no additional cost. His rates are excellent! He will be the first person I call for any of my future heating and cooling 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.
