[quote=Anonymous][quote=Anonymous]Thank you, electrician friend! So our current setup is hydronic, heat-only, and we have ducts and 3 separate air handlers. The air handlers will be replaced 1-for-1. The tankless water heater that heats the water for the hydronic system runs on gas. The HVAC guys are proposing various things, but the least ridiculous proposal involves 35A + 30a + 30a for 84,000 BTU total across 3 units (adding AC coil for each air handler). So same 84,000 BTU as you’re calculating with a high SEER unit. Now I’m wondering if this design is also constrained by the 3 separate air handlers and duct setup. The house is 2-stories but mostly 1 room deep so it’s pretty stretched out. One of the guys was adamant that higher BTUs and less air handlers/AC units would not work and would be less efficient.[/quote] I agreed with electrician till you posted this. 3 units is a big load.
