I am at a crossroads and need to decide on which direction to go.
One of my systems is on its last leg. A Carrier 48GS gas pack 3.5 ton system which services my downstairs.
I have received bids from 4 different installers on systems. Two of them quoted Trane equipment. The company I have decided to move forward with is the best priced and has the best feedback / reputation in my area. 2 of the companies provided a load assessment that stated a 3.5 ton system was appropriate for my downstairs.
That said, I need to decide between the Trane XL16C or XL14C (both dual fuel) systems.
1) The XL16C does not come in 1/2 ton sizes. As such should I go with a 3 ton or a 4 ton? My concern is that the 3 ton will struggle to keep the house cool on those blazing summer days. **Over the last 3 years we have seen periods of extreme here in NC. i.e. 95+ for 2 weeks or more.
2) Would the XL14C in the 3.5 ton, although only single stage be the better all around system over the XL16C?
