"Since I have two furnaces, two air-conditioning units and a whole house air filtration system, it was too expense for me to afford the yearly service costs. Ed, the technician, and Steve, the Service Manager, helped me find filters that will help with my allergies and asthma and yet were affordable. I used the "Comfort Care" plan, which has discounts for parts and includes service for all my units."

"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."

"Had a new HVAC unit installed and they did a great job! George and his crew were extremely knowledgeable and friendly. They arrived on time and cleaned up after themselves. The cost was reasonable. I’m very happy with their work and will definitely use them again if the need arises. I even recommended them to my 80 year old mom and she was very impressed as well. Mom and I highly recommend!"

FAQs for air conditioning projects in Loudon, 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.
