About Cooling Load Guide
Cooling Load Guide was created to help homeowners make better air conditioning decisions through clear, practical, and engineering-based information.
Choosing the right air conditioner size is one of the most important factors affecting comfort, energy efficiency, humidity control, and long-term operating costs. Unfortunately, many homeowners are forced to rely on conflicting advice, oversimplified sizing charts, or sales-driven recommendations.
Our goal is to make HVAC sizing and air conditioning concepts easier to understand by providing accurate, research-based information written in plain English.
About the Founder
Hi, I’m Caner.
I have worked in the HVAC industry for more than 15 years as a Heating, Ventilation, and Air Conditioning (HVAC) Design Engineer.
Throughout my career, I have been involved in the design and engineering of residential, commercial, hospitality, healthcare, industrial, and large-scale building HVAC systems. My experience includes cooling load calculations, equipment selection, duct design, airflow analysis, ventilation systems, energy efficiency studies, and HVAC project design.
Cooling Load Guide was created to bridge the gap between technical HVAC engineering knowledge and the practical questions homeowners face every day.

- First-time home buyers
- DIY researchers
- Property owners comparing HVAC options
- Anyone trying to better understand air conditioning systems before speaking with a contractor
Independence
Cooling Load Guide is an independent educational website.
We do not manufacture HVAC equipment, sell air conditioners, or provide installation services. Our goal is to provide objective information that helps readers make more informed decisions.
Important Disclaimer
The information provided on Cooling Load Guide is intended for general educational purposes only.
Any sizing estimates, BTU calculations, tonnage recommendations, or cost estimates should be considered preliminary guidance. Final equipment sizing and system design should always be verified by a qualified HVAC professional using a complete load calculation, such as an ACCA Manual J analysis, along with project-specific conditions.
Professional evaluation is especially important for new construction, system replacements, ductwork modifications, and homes with unique design requirements.
