"Chris installed two Mitsubishi mini-split air conditioning/heat pump systems in our home. Chris responded quickly to our request for a proposal. He came to our home in a few days, did a thorough review of our options, explained how the systems work and patiently answered all our questions. He sent us his proposal the same day and his estimate was very reasonable. He installed our system in one day even though it required him to work late into the evening due to a delay in the delivery of the equipment caused by a major traffic accident. Chris is very professional and a pleasure to deal with. We recommend him without reservation."

"My 30 year old boiler, with much fanfare chose to conk out, leaving me without heat as an impending snow storm was in the forecast. After getting outrageous quotes from another HVACs for a new boiler, I lucked out in finding Pro Heating. When Sean learned I was without heat, he gathered his A team and within a couple of days (other companies were saying it would be weeks)installed a high efficiency boiler that was less costly and is far superior to the less efficient boilers that the other companies quoted. Sean and his team are incredibly knowledgeable and professional. I highly recommend Pro Heating and Cooling, and have done so already to friends and family!"

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.
