HVAC Load Calculations
Manual J (Residential) & Manual N (Commercial)
Carstairs Energy Calculations is now pleased to offer HVAC load calculation services.
We understand that both comfort and efficiency are necessities when it comes to HVAC systems. Correctly sized HVAC units and register placement make for a more comfortable indoor environment, which is why it is so important that proper load calculations be done to ensure correcting sizing of your heating and cooling equipment. Load calculations are done on federally approved forms, in accordance with manual J (residential) and manual N (commercial), and show the heat loss and heat gain for every room. We offer flat rate service for residential and low prices for commercial.
What we will need:
- Floor plan (showing window, wall, and door dimensions)
- Site plan (showing building orientation and building areas
- Sections (showing insulation and ceiling heights)
