About Us

Comfort Starts at Home — and in the Community

At All In Heating & Cooling LLC, we believe comfort starts at home—and in the community we serve.

Founded in May 2023 by longtime HVAC professionals Ronnie Dodd and Justin Foster, our company was built on a shared vision: to provide honest, dependable heating and cooling services that families and businesses in Lake and Mendocino counties can truly count on.

With decades of combined experience in the trade, Ronnie and Justin saw the need for a service-first approach rooted in trust, transparency, and care.

Locals Who Understand Local Needs

Both Ronnie and Justin were raised in Mendocino County, which means they understand the unique needs of local homes, businesses, and climate conditions.

That local knowledge helps us deliver high-quality HVAC solutions — from maintenance and repairs to complete system installs — that are tailored to this region.

As a family-oriented business, we treat our customers like neighbors and every job like it matters.

Giving Back Matters

Our commitment to community goes beyond heating and air. We proudly support local youth sports, FFA and 4-H auctions, and community-focused programs that help build a better tomorrow.

When you choose All In Heating & Cooling, you're not just hiring an HVAC contractor — you're choosing a local team that’s all in on your comfort and your community.
