Need Help With HVAC Decision
Kindly share your expertise and knowledge regarding the following:
3400 sq. ft., full sun exposure, facing West, gas-hot air heat, existing system is 19 yrs. old, R-50 insulation in 2/3 of attic, R-19 in remaining 1/3, house located in Phila., PA area. Existing system is Bryant 90+ AFUE, 132,000 BTU Furnace and 4 ton condenser and coil. The a/c struggles to cool the house on the hottest summer days and I have always wondered if a/c was undersized by the buider.
1. Rheem RGRM-10EZAJS, 105,000 BTU, 95% AFUE two stage, variable speed, furnace, Rheem 14AJM56 14.5 SEER, 54,000 BTU Condenser, and RCFLHM60 5 ton Coil. Price - $6100.
2. Lennox EL296UH110XV60C, 110,000 BTU, two stage, Variable Speed, 96% AFUE, furnace, Lennox XC17-060, 15 SEER, 5 ton a/c condenser unit, and Lennox CX34-62D-6F Coil. Price - $6100.
Your advise/input is most appreciated. I think I have two pretty good choices, but need your help in making final decision. The prices are the same due to price matching. Any other suggestions/input?
