About HVACBase

HVACBase is written by Marko Visic, a physicist (BSc, Faculty of Mathematics and Physics, University of Ljubljana). While studying thermodynamics, he became interested in heat-transfer applications — the equations that explain how heat pumps, air conditioners, insulation, and airflow behave in a real home. HVACBase grew out of that interest: a site that starts from the physics of heat transfer and connects it to practical HVAC decisions, backed by primary-sourced specifications.

Why this site exists

Most HVAC information online tells you which unit to buy. HVACBase tries to explain why — the thermodynamics underneath the spec sheet — so you can reason about your own home: your climate, your heating load, your cooling load. The goal is to help any homeowner understand how HVAC works and which system actually fits their situation, and to give people enough well-sourced grounding to understand the systems they already own.

How we source

Every specification on this site comes from manufacturer documentation, the AHRI Directory, or ENERGY STAR. Where a number can't be verified against a primary source, it isn't published. We don't run a testing lab and we don't claim to — our value is clear explanation of verified data, not invented measurements.

What this site is not

HVACBase is an independent education site. Marko is a physicist, not a licensed HVAC contractor — nothing here is a substitute for a licensed professional for installation, sizing sign-off, repair, or safety work. Always have equipment installed and verified by a qualified contractor.
