"John has taken care of all my HVAC needs for over 15 years. It's always an easy decision for me . . . I would not use anyone else but Admiral Heating and Air Conditioning, and I have recommended John to many friends over the years. My father was a home builder and I am an engineer, so I know what to look for in terms of professionalism, doing the job right, pride in one's workmanship, attention to detail, and treating the customer fairly and with respect. John and his company excel in all these areas. Thank you John for another outstanding experience with the install of the new American Standard heating and cooling package."

"CM Walter Heat and Air did a fantastic job on my older AC unit. We had another company come out first. They couldn’t get the parts in and installed for another three days and the quote seemed high so I called Martin and he came out the same day. Diagnosed the problem and had me back up in running in minutes. He also saved me a ton of money. After it was all said and done he saved me over 800 dollars! I highly recommend this company to anyone in need of AC work!"

"Dustin was very responsive as soon as I entered my request and continued to be very communicative and knowledgeable throughout replacing two fixtures and looking at some outlets. He did great work on what I needed him to do today and I am sure he would do the same on anything else I needed!"

"Our A.C went out of course on a Friday night. Wayne was quick to answer the phone, polite, and knowledgeable. He talked me through somethings and provided an affordable quote. He promptly showed up and right away I knew that he knew what he was doing and talking about. Even though it was already late on a Friday night he was kind enough to go out and secure the replacement part that was needed and returned to quickly fix the air. Within about 3 hours of placing my call my air was fixed quickly and at a great rate. Would trust Wayne with all my AC needs in the future."

FAQs for air conditioning projects in Lenoir City, TN

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.
