We consider the building envelope, ductwork, insulation, ventilation and equipment together. Comfort, indoor air quality, safety and durability belong in the same conversation.
About Project Probono · Lehigh Valley Home Performance
Building science.
A human purpose.
Everyone deserves to feel at home in their home. Since 1997, that belief has guided our work—from understanding the problem to making the improvements that matter.

Shared purpose.
Michael John Ohm has worked in energy diagnostics and building-performance retrofits since 1997. His Lehigh Valley roots—and his commitment to equity, craftsmanship and community—shape Project Probono today.
Our work with utility and weatherization programs has connected us with families throughout the region. If you or someone you know participated in PPL, UGI or county weatherization programs over the years, our paths may already have crossed.
Our name reflects the greater good: professional expertise, clear guidance and service grounded in the community we call home.

The Project Probono standard
Understand the home.
Improve what matters.
A home’s air, heat, moisture and mechanical systems influence one another. Our recommendations start with those relationships—and with the people living there.
Let testing guide the work.
Blower-door testing, duct-leakage testing, pressure diagnostics and infrared imaging help reveal where performance is being lost—and what deserves attention.
Recommend with purpose.
Every home needs its own plan. Duct cleaning, Aeroseal, air sealing and insulation can stand alone or work together when the findings support them.
Verify the improvement.
When work changes building performance, post-work testing documents the difference. Measured results provide accountability beyond the installation itself.
What working with us feels like

We work best with people who value transparency, thoughtful improvements and the well-being of everyone in the home.
