How Does This Impact Sizing?
• Typical house
– 50,000 BTU Heat Loss
– 30,000 BTU Heat Gain
– Sizing of T THERM GEO
– Select 4 Ton two stage
– Heating capacity is 44,420 BTU so we are sized for 89% in
heating
– The homeowner will need to use resistance heat at -10 F
– Cooling capacity is 46,100 BTU (1st stage) so we are oversized
by 65% which is fine due to our deep coil, cooling
dehumidification will not suffer

10. When COMFORTmatters
How Does The
Competition Size?
• Same house
– Sizing of other manufacturer
– Select 4 Ton
– Heating capacity is 36,500 BTU so we are sized for 73% in
heating
– The homeowner will need to use resistance heat at 4 F
– Cooling capacity is 38,500 BTU (1st stage) so we are
oversized by 28% which beyond the recommended max
oversize of 25%.

11. When COMFORTmatters
If We Follow
Recommended Sizing
• Same house
– 25% Maximum cooling over sizing
– Select 3 Ton
– Heating capacity is 26,500 BTU so we are sized for 53% in
heating
– The homeowner will need to use resistance heat at 22 F
– Cooling capacity is 27,500 BTU (1st stage) so we are
undersized by 8% which is within the recommended max
oversize of 25%.
