HVAC maintenance
I use no one for regular maintenance. I changed filters regularly and put 50% solution of white vinegar and water down the condensate line twice a year. My 19 year old Trane condensing unit is still purring along. I have never had a service call on it. Maybe it is hard to stop a Trane! And that’s coming from someone that sold Carrier equipment in five states for 30 years! I even wax my old Trane unit at least once a year. It still looks new. I use to train dealers to always wax the outdoor unit of the customer that is receiving the maintenance service. More customers felt like their unit ran like new when it looked good again!!!!!!
