Home Performance Diagnostics

The AC company says everything’s working, but parts of your house still won’t stay cool, or the humidity won’t come down. Maybe you’ve already tried more insulation or more attic ventilation.

Vision Home Performance runs full home diagnostics with a blower door and tells you exactly what’s going on in your home, with data, and how to fix it.

Pressure gauge reading on ductwork in an attic

Basic Consult and Diagnostic

$400

Up to 2 hours on site, using tools like:

A thermal camera to find missing insulation
A smoke pen to locate air leaks
A visual look at how your ventilation is working, including bath and kitchen vents
Room pressure imbalance testing: can you close your bedroom door at night and still know it’s going to be comfortable in there?
Static pressure testing: is your AC system being choked?
Basic humidity and moisture testing

Includes a basic report with our findings and suggestions on how to move forward.

These tests can be quite revealing, but they’re still limited in giving you real, measurable data about what’s wrong in your home.

Our recommended path

Full Home Performance Diagnostic

$1,200

Data-driven, inarguable answers about what’s going on in your home. Everything in the basic diagnostic, plus up to 6 hours in the home:

Blower door testing: we depressurize the house and pinpoint all the air leaks
A basic idea of how sealed your ductwork is, and whether you need to move forward with a duct leakage test
Measuring whether your attic is fully connected to the outdoors instead of the conditioned space
Detailed measurements and data, with accurately calculated attic ventilation requirements
A detailed report with specific instructions to give other contractors, or recommendations for contractors we trust

Anything less than a full diagnostic with a blower door is really just guessing. The blower door is the truth. It’s how we get down to the real science of what’s going on in your home, and it gives you the path forward to never have to deal with these issues again.
