"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."

"I had a Klimaire 36,000 BTU Split-type Heater/Air Conditioner installed by Jake Prevost and an electrician. They did an awesome job. Both were very professional and knowledgeable. The installation also included electrical wiring from the fuse box to the unit, along with electric wire guard covers. The unit worked perfectly by the time they were done. I was also very surprised that they cleaned up the entire area and removed all of the trash and large boxes that came with the inside and outside unit. Highly recommended!"

"Adam examined all the options to determine why the air conditioner wasn't working. Other repair service companies had determined a new air conditioner was needed. Before recommending that option Adam examined why the air conditioner wasn't working and fixed it. Thanks Adam I will recommend you to all my neighbors."

"Everything went great. Matt remodeled my bathroom and updated the electrical panel. Matt was rehired in the summer to build a large deck out back and it came out amazing! He also built a 40ft long retaining wall for my trees and garden. Everything looks amazing and I love his work."

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.
