"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."

"Travis (the contact person) explained the options very clearly at the time of the estimate, and clarified for me all the terms associated with this type of installation. Not only did they install the air conditioning unit in one day with minimal household disruption, when they heard that I was getting a new gas stove in the next couple of weeks (replacing electric), and needed someone to bring a gas line up to the kitchen, they agreed to do that for me as well since their "gas guy" had to perform specific operations for the air conditioning unit. They just added an extra $200.00 to my bill, which was 1/3 the cost I had gotten earlier from a plumber. When the gas stove arrived, I called Northstar and they arranged for their "certified" gas guy to come and "install' the gas range. What a deal! Great customer service."

"Mike was friendly and efficient. He hooked up our gas stove (and had warned us when we first called to make sure we had the proper electrical for it...which we didn't and arranged thanks to him) . He also took time to check out another job we might do in the future. Would definitely work with him 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.
