"My wife and I decided to have a split entry heat pump installed, so I contacted 4 contactors. JoMac was first to respond, first to come out, first to submit a bid, and after I accepted the bid, Joe completed the work in short order. Joe listens to the consumer well and is anxious to do a good job on the project; he knows that happy customers mean more business. Joe is polite and outgoing; he even brought cuccumbers for us. Two days after the job was done, Joe called just to see how things were going."

"Hired the Comfort Company to install a new propane high efficiency furnace, air source heat pump and take out my old nasty oil tank. Very satisfied and my wallet took a smaller hit than I thought it would! Highly recommend!"

"About an hour after calling Kaduce Plumbing and Heating, the service person arrived and promptly set about replacing our recirculating pump on our hot water heat furnace. He did a great job, and we had heat in about 30 minutes after he arrived. The service man even questioned why I had throttled down one of our heat lines by about 70%. That line goes to our upstairs and with an open stairway, the heat goes upstairs so we need less heat up there. Even throttled down, our upstairs stays about 10-15 degrees warmer than the ground floor. The service man did an excellent job of cleaning up after himself, so it's neater around the furnace than when he arrived."

"Vlad was great! We had 2 old through the wall air conditioners that weren't working and needed to be replaced. The air conditioners weren't installed properly by the previous owner of the house. Vlad installed the supportive sleeves that the air conditioners seat into. He also put the very heavy units into the sleeves himself! I was very impressed with the quality of work he did. He trimmed and sealed the 2 sleeves in the walls and they look great. He is very skilled and knows what he is doing. He was a very nice person and a pleasure to work with. I would definitely hire Vlad again!"

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.
