"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!"

"Anthony and Kaitlyn were amazing! They both went over and beyond helping me with my warranty co. Witch I had been dealing with for 4 mouths. They got things done. Not only did they help with the warranty co they went over all my options, cost and time frames. Worked around my schedule. Showed and explained to me in detail what was wrong with my 2 units. Showed up for appointments. What a blessing! I cant even begin to tell you how how much I appreciated all the extra effort. Both Anthony and Kaitlyn (put in hrs.) dealing with my warranty co. And that no joke! I would highly recommend Honest AC to everyone and they are extremely knowledgeable, honest and affordable. They make it real clear in all that they do! THERE CUSTOMERS MATTER. Unlike my warranty co. LOL Honest ac will have me as a customer for life! Wish you the best success to you both. Thank you! thank you! Anthony and Kaitlyn for your help I needed it."

"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."

FAQs for air conditioning projects in Oak Ridge, 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.
