You guys have helped me in the past, thanks. I am a licensed plumber and electrician by trade.At the end of last summer my Lennox HS 14 went out and my Lennox Pulse(propane) furnace is on its last leg( I know about the heat exchangers).
Its now time to replace everything. I have good Lennox and Trane dealers nearby that I sometimes work with on jobs. I am just starting my search for equipment. The house is in Ga.(high humidity) and is a 2400sq ft.ranch with a basement(very well insulated,2x6 exterior walls,basement is nearly all underground with insulation on the outside of poured walls and under slab, 1" foam outside of that and 16inches insulation in the attic). The Pulse was a 60,000btu and the HS14 was a 2-1/2 ton on high. The duct work is all metal, with supplys and returns in each bedroom and a large one in the living room.4 bedroom house with a dining room up stairs and one room and a bath in the basement conditioned.
I want to get the most efficient replacement system with a Hepa type filter system. I need your suggestions on system type>split,dual fuel,heat pump etc. The electric rate is reasonable and I have propane which is high at this time. 200gal this year was $500.00. It was a warm winter and I did not use the whole tank this year but usually I used 1-1/2 tanks(300gallons) a year propane with the old Pulse(96% efficient I think). I have all types of water heaters installed(electric,instant,&propane tank) and can change to any one of those with some valves. I might be interested in heat recovery system if it would help the A/C equipment. I can provide any other information in a later post. Thank you for any insights, David
