Just finished up a routine, maintenance and tuneup on a 90% Goodman natural gas fired furnace in the Bear Delaware area. Noticed that the furnace was overheating when I was getting my readings and later found out that most of the registers were closed on the downstairs. On top of that they were a few more recommendations that I may to the client regarding the overheating of the unit. And I also noticed a leak coming from one of the fittings on the exhaust vent piping. We discussed solutions and plans of attack and will be back to conquer these tasks. Thank you so much for allowing us in your home, and trusting us with your comfort
