Called out today for a second opinion. Client stated that another company stated that she needs to get a bigger AC. The second floor is the only floor that has ductwork. First floor has a window unit. The second floor is around 1500 square feet and equipped with a three ton unit. Insulation levels are correct. There are 40+ windows throughout the home. There is no attic vent/fan. The machine is operating due to the manufacturer specifications. There are many other factors of heat penetration between the windows, floors and first floor. The best course of action would to be to install a mini split on the first floor to eliminate the second floor unit from overworking. I did patch the hole in the air handler to stop the unit from pulling in hot attic air. Client wants to look at her options and make a decision later. She is aware of the price range for mini split install and financing is available. Thank you for always choosing Total Air!
