We just moved into a 22 year old home with original AC. Previous owners had likely not cleaned the AC in at least 5 years. Prior to Cole J's Clean & Check visit, the AC was struggling to turn on. The A/C finally decided to shut down just as Cole had finished attaching his instrumentation to check the refrigerant level. After some troubleshooting Cole found that multiple parts failed on the AC. Cole had the parts on his truck. He hooked up the new parts and double-checked the system and by the time he left my home the AC was running good as new. I appreciate the time and care Cole took to troubleshoot my AC. Cole is friendly, knowledgeable, and honest. Cole explained why each part needed replacement. The repair cost was reasonable and based on this experience the Heating/Cooling maintenance agreement cost is a good value. Based on my experience with Cole, I would not hesitate to have Buchner replace my Heating and A/C system when the time is right.
