Manual S
Selecting the Right Residential HVAC Equipment
Once your precise heating and cooling requirements are determined by the Manual J report, the Manual S (Equipment Selection) process begins. This step is mandatory for energy code compliance and is vital for selecting the right size and type of furnace, air conditioner, or heat pump. Trust Right Foot Design to match your specific Manual J loads with correctly rated, efficient HVAC equipment, avoiding the high cost and discomfort of oversized systems.
The Importance of Accurate Equipment Sizing
Avoid Short Cycling: Properly sized units run longer, dehumidifying the air better and extending the life of the system.
Achieve Peak Efficiency: Ensure your equipment operates at the manufacturer's rated SEER, EER, or AFUE.
Prevent Future Issues: Eliminates the common problem of oversized equipment (which leads to higher energy bills and uneven temperature control).
Satisfy Permitting Requirements: Provides the necessary documentation proving that your selected equipment meets or exceeds the loads calculated in your Manual J report.
How Right Foot Design Performs the Manual S Process
The Manual S requires performance data. Our designers work with the specific equipment models you plan to use, utilizing manufacturer-published expanded performance ratings. We verify that the chosen unit's sensible and latent capacities meet the requirements identified in your Manual J.
