How do I determine if I need a 3 ton or 4 ton air conditioner?
About 6 months ago I came to this forum and received some excellent information about HVAC systems.
I have two quotes and both vendors suggested the same furnace; The Infinity 96 Two-Stage Gas Furnace Model: 59TN6.
However, one vendor suggested a 4 ton Infinity 21 SEER air conditioner and the other vendor suggested a 3 ton 16 SEER air conditioner.
How do I make the determination on if I need a 3 ton or 4 ton system? I'm in Michigan and the air conditioner is primarily used during the summer months. My air conditioning bill typically peaks in July only.
The vendor that recommended the 3 ton system did take measurements of the house. I'm not sure if the other vendor did. Also, I currently have a 4 ton air conditioning unit which is probably the original. The home was built in 1967.
Please help. Thanks.
