"I was very impressed with this company from beginning to end. When they gave me an estimate, they spent 90 minutes with me to make sure I selected the right furnace and AC. The crew came two days later and installed the furnace and AC in one day. Great job! Very happy with the whole experience. I highly recommend this company to others."

"We had them Replaced furnace and air conditioning unit. It was installed about a year ago but they came out for a regular service about a month ago. the service was free, part of the contract. I have no complaints, it was all good. They were responsive. they were punctual. I have no problems, it was a good deal when I bought it, it's a good deal now. I don't have any issues with how the service went. i bought it through them and I have no regrets and everything was the same as I felt when I bought it. It was a good deal, I made the right choice. Anytime you buy a major system and it doesn't go right you have a problem. I'm a happy camper.1 worker took less than an hour to complete."

"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

FAQs for air conditioning projects in Gainesville, VA

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.
