Our Story

Fresh Air Heating & Cooling, a family-owned business since 1987, has been a trusted name in the St. Louis community for decades. Founded by Meg and Mike Sinn and now proudly operated by their children, the company began in a home and rented garage before growing through referrals to establish its roots in Chesterfield Valley. In 2003, a merger with the historic Weinrich Heating Co., a West County staple since 1947, strengthened their legacy. Today, from their location on Edison Avenue, they continue the founding purpose: delivering superior residential and light commercial HVAC sales and service, providing quality products at fair prices, and building lasting relationships with their neighbors.

Common Questions

My Chesterfield home's air conditioner is short cycling (turning on and off frequently). What could be the cause, and how can Fresh Air Heating & Cooling help?

Short cycling in Chesterfield is often caused by issues like a dirty air filter, refrigerant leaks, or an incorrectly sized unit for your home. It's a problem that strains your system and increases energy bills. Our NATE-certified technicians diagnose the specific cause—whether it's a repair like sealing a leak or a recommendation for a properly sized replacement system—and provide a clear solution to restore efficient, reliable cooling for your home.

What does your HVAC installation warranty cover for a new system in my St. Louis County home?

We stand behind our installations with confidence. For any new HVAC system we install, we provide a five-year warranty on labor. This is in addition to the manufacturer's warranty on parts. It's our commitment to ensuring your long-term comfort and peace of mind, backed by our family's decades of experience serving the local community.

Why should I consider a maintenance service agreement for my furnace and AC in the Chesterfield area?

Regular maintenance is key to preventing common local issues like evaporator coil freeze-ups and extending the life of your equipment through our varied seasons. Our service agreements provide scheduled tune-ups, priority service, and discounts. This proactive approach helps catch small problems early, improves efficiency to manage energy costs, and ensures your system is ready when you need it most.
