Building Science That Actually Matters
Tightness, airflow, humidity, and fresh air — diagnosed and designed by an engineering-minded Integrity team, not guessed from a nameplate.

Why This Cluster Exists
Above-and-Beyond Comfort Engineering
Most HVAC companies sell equipment. Premium homeowners ask harder questions: How tight is the house? Where is humid air leaking in? Are the ducts actually delivering the CFM on the nameplate? Do we need an ERV, a dehumidifier, make-up air — or all three?
Integrity can answer those questions. We have an engineer on the team who is deeply analytical and solves comfort from every angle — envelope, airflow, humidity, and fresh air — not just the outdoor unit. That is building science: the skill set behind top-dollar diagnostics that fewer than one percent of companies in the market truly deliver.

How a Florida Home Actually Breathes
Tap each system on the house — or step through — to see leaks, testing, ducts, fresh air, and humidity as one connected story. This is the diagnostic view Integrity uses before anyone talks about equipment.

Core Guides
Start With the System, Not the Box
Intent 1 learning guides — definition, when to use, failure modes, and the Integrity approach. Pair them with humidity and IAQ pages you may already know.
Connected Learning
IAQ, Humidity & Sizing
Building science does not replace these guides — it completes them. Dehumidifiers, filtration, and Manual J sizing sit on the same foundation.
