HVAC repair, AC repair, and new HVAC system installation for Warrenton, Wentzville, Troy & O'Fallon. 500+ five-star reviews. Founded in 1946, Omar Schraer served Warrenton and Montgomery county Missouri for decades building and installing furnaces in the small community. In the 1950s, Omar added air conditioning to the services he provided and from then on was known as Schraer Heating and Air Cond

itioning. The company was run by a tight-knit group of family up until 1994, when the company was purchased by Scott-Woolf Incorporated, run by brothers-in-law Gary Scott and Bill Woolf. Gary and Bill had begun serving the Warrenton area in 1993 with one truck and a customer base of about 300 people, and their purchase of Schraer Heating and Air Conditioning reinvigorated the company. From the beginning, Gary and Bill committed to continue Omar’s legacy, and the enterprise continued to be a family affair as several generations grew up and joined the family business. Sons, daughters and cousins tell stories of building racetracks in the warehouse from ducting and riding bikes in the parking lot late into the night as the company grew both in capability and clientele. And many of those same kids joined the company as it expanded to dozens of local counties, added numerous services, and established partnerships with suppliers like Lennox to carry only the most innovative systems. The years since have been full of major leaps forward and challenges conquered, from airlifting HVAC systems by helicopter for commercial installs to serving the unprecedented growth of the communities west of St. But no matter how Schraer has grown, one thing has never been forgotten—that the heating and air conditioning of a home is its beating heart, and it’s with that same heart that Schraer serves its community, and since the beginning has participated in civic cleanups, local parades, and purchases a bull every year at the local 4H auction. The people that work at Schraer treat every home like it is their own. Each new job is a chance to help one of our neighbors first, and a “service call” last. When we talk about comfort, we’re not just talking about heating and air conditioning, we’re talking about giving our heart to our communities.

NEW Blog Post: Is It Time to Seal Your Air Ducts? Signs Missouri Homeowners Shouldn’t Ignore 🔧⚠️

Your ductwork plays a crucial role in keeping your Missouri home comfortable year-round.

If you’re considering air conditioning maintenance in Warrenton, don’t overlook the condition of your ductwork, because sealing leaks can improve comfort and help your HVAC system operate more efficiently.

PRO TIPS FROM SCHRAER AIR EXPERTS 🔧🏡

Your HVAC system does a lot behind the scenes to keep your home comfortable, but a few small habits can make a big difference.

✅ Clear leaves, grass, and debris away from the outdoor unit
✅ Pay attention to strange smells, sounds, or weak airflow
✅ Schedule routine maintenance before the busiest heating or cooling months

Small maintenance habits can help your system run more efficiently, reduce unnecessary strain, and catch issues before they turn into major breakdowns.

No funny business. No guesswork. Just smart home comfort habits that help protect your system and your peace of mind.

The song “One Piece At A Time” by Johnny Cash is actually a great metaphor for your HVAC system. They can’t be built over the span of a few decades, each part has to fit with the other.
