I am in the process of replacing my residential HVAC.
Existing Unit Data:
• Houston, TX.
• 1500 sq ft, single story; ceiling fans in each room.
• Existing unit is 3.5 tons York H2RC042S06 A /C; 80 kbtu furnace; York database shows the unit is 12 SEER, but local tech said it was 10 SEER.
• Existing unit is 10 years old.
• Evaporating coil leaking.
• Existing furnace gas control (winter) unreliable.
• Plan to stay in this house for several years (single, retired).
I have been quoted a couple of installations to replace everything: condenser, evaporator, furnace, etc. The contractor is suggesting:
• 4.0 ton Lennox A/C; either 13 SEER or 16 SEER; for example XC16 Condenser unit.
• 90 kbtu furnace; for example G60UHV furnace.
The 16 SEER unit is considerably more expensive than the 13 SEER, but I am drawn to it because of the really hot summers we are having in Houston, and electric costs are going up a lot.
So, my question here is whether it makes sense to go with a 16 SEER replacement unit in Houston vs. a 13 SEER unit?
