Who we are
Family-owned.
Not backed by private equity.
Family-owned HVAC service built on trust, craftsmanship, and long-term relationships — not investor profits.
No private equity. No outside investors. Just our family taking care of yours.
— Jenna Fortman, Owner
What we do
Furnace and AC work, done by the crew that answers the phone.
Your home is your fortress. We protect your comfort. We diagnose before we quote, put the number in writing before anyone opens a panel, and carry the parts that actually break so most repairs finish in one visit.
Where we work
Plainfield, IL, and the western suburbs.
Plainfield, Naperville, Yorkville, Bolingbrook, Oswego, Wheaton, Lisle, Minooka, Shorewood, Aurora, plus nearby towns within a reasonable drive. Call and ask if you're just outside that list.
Family-owned

Certified, insured, bonded
Illinois doesn't require an HVAC license. We got certified anyway.
There's no statewide HVAC license in Illinois, so "licensed" isn't a claim we can honestly make — but our techs hold EPA Section 608 certification (required by federal law to handle refrigerant) and NATE certification, the industry's voluntary standard for technician competence. FortHouse carries full insurance, including workers' compensation, and is bonded.
Equipment we regularly install
Trane, Lennox, Carrier, Goodman, Bryant, Rheem.
