2nd time in 12 years that I have called Columbus Worthington Air to come out to see what the issue was with HVAC system. This time it was for the furnace that would run, stop and start up 2 minutes later. The tech cleaned whatever needed to be cleaned, the furnace was working g properly again, checked the entire system but would need to replace the blower motor and the capacitor, which if I didn't carbon dioxide could leak. One month later the furnace did the same thing. This time I had a HVAC company that was recommended by the furnace manufacturer come out. The tech ran the same diagnostics, cleaned the same part as Columbus Worthington Air, but noticed that the air filter was put in wrong and that there was no condensation, and recommended that I switch to a different kind due to airflow being restricted with the one I had. The blower motor and capacitor was in good condition...no need to replace. Columbus Worthington Air almost cost me over $1000 if I listened to their tech when all that needed to be done was turn the air filter around. Be aware when using Columbus Worthington Air and get a second opinion.
