At Cooling Load Guide, our goal is to publish educational HVAC content that is accurate, practical, and easy to understand. To help ensure the quality of our articles, we reference widely recognized industry standards, government resources, and publicly available technical documentation whenever appropriate.
Our content is written for homeowners, but it is informed by established residential HVAC principles rather than personal opinions or marketing claims.
Industry Standards
Many of our sizing, airflow, and efficiency guides are based on concepts commonly used throughout the HVAC industry.
These include standards and methodologies developed by recognized organizations such as:
- Air Conditioning Contractors of America (ACCA)
- American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)
- Air-Conditioning, Heating, and Refrigeration Institute (AHRI)
These organizations publish technical guidance that helps establish common practices for residential HVAC design, equipment performance, and installation.
Government Resources
Where appropriate, our articles also reference publicly available educational resources from government agencies.
These may include information related to:
- energy efficiency
- HVAC operating costs
- home energy savings
- equipment efficiency standards
- consumer guidance
Examples include resources published by the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA).
ENERGY STAR Guidance
Many efficiency-related articles discuss concepts commonly associated with ENERGY STAR recommendations.
ENERGY STAR resources help homeowners understand topics such as:
- energy-efficient equipment
- cooling system upgrades
- operating costs
- seasonal energy savings
Manufacturer Technical Documentation
Equipment manufacturers publish technical specifications that explain system capacity, airflow requirements, efficiency ratings, and installation recommendations.
When discussing equipment characteristics, we may consult publicly available technical documentation from HVAC manufacturers to better explain general residential cooling concepts.
References to manufacturers are provided for educational purposes only and should not be interpreted as endorsements.
Residential HVAC Principles
Many articles published on Cooling Load Guide explain established residential HVAC concepts, including:
- Manual J load calculation principles
- BTU calculations
- air conditioner tonnage
- airflow (CFM)
- humidity control
- duct system performance
- equipment staging
- SEER2 efficiency ratings
These concepts are widely recognized throughout the residential HVAC industry and provide the educational foundation for many of our guides.
Regional Information
Cooling requirements vary significantly across different regions of the United States.
When publishing state-specific sizing guides, we consider general regional characteristics such as:
- typical summer temperatures
- humidity levels
- cooling season length
- solar heat gain
- common residential construction practices
These regional factors help explain why equipment recommendations may differ between similar homes located in different climates.
Independent Editorial Process
Cooling Load Guide is an independent educational resource.
Our articles are written to help homeowners understand HVAC concepts and are not sponsored by equipment manufacturers, HVAC contractors, or product retailers unless explicitly stated.
Editorial decisions are based on educational value, clarity, and technical consistency rather than commercial influence.
Continuous Review
Industry standards, efficiency regulations, and residential HVAC technology continue to evolve.
We periodically review our articles and update information when appropriate to reflect current terminology, improved educational resources, and changes within the HVAC industry.
