"Will Nichols, the owner, attempted the fix my 24-year-old air conditioning unit before telling me I needed a new one. Took most of the day to replace it since I have a boiler and not a furnace, so the air conditioning is an entirely separate unit. I was completely satisfied with the experience and will use A1 for routine maintenance."

"We were extremely pleased with the service of FinMar Comfort. Sean was knowledgeable and professional. He installed a split heat/air conditioning unit in our sunroom so we could use it all seasons. He went out of his way to find us a unit that was reliable but fit our budget. Sean also helped us every step of the way with permits and warrenty information. Would defintely recommend FinMar Comfort"

"He is very knowledgeable and thorough and better than your average everyday HVAC service provider."
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.
