Furnace Tripping on High Limit & No sealed Ducts

 

Another prime example of what happens when the lowest bidder wins. This furnace was going off on a high limit due to not enough air flow. We had to run another air duct line to help exhaust air. Also, the ducts were not sealed we were able to stick our finger into the air gaps due to how large they were. The customer has allergy problems and was trying to use a premium air filter except her entire HVAC system was pulling in unfiltered air through all the gaps.
