"Noah was very quick to respond to our inquiry. My husband and I were helping my MIL find quotes to replace her Central Air unit. Noah was very flexible with our schedule and made sure to answer all of our questions. Hometown Heating & Air had the best quote by far but still offered a great product and amazing service. The day of install they showed up early, got working and didn’t need us for anything. I highly recommend reaching out and hiring them!"

"We found Brian and Josh off of Angies list. When you walk into a large project not knowing the company, you hope it goes well. Well we are very pleased. They converted our oil furnace to gas and put in a new water tank. Both my husband and I are very pleased with this company and we will be calling them when we put in the air conditioner. If your looking for people that are very knowledgeable as well as friendly then give them a call, you won't be disappointed"

"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

Patrick got back to me promptly, was very receptive in answering all of my mother's questions, and was able to start job within a couple of weeks from first call.

"Mike the technician was a pleasure to work with. It took two visits to fix our problem with the AC, but we are very happy customers."
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.
