About Us

We’ve been keeping homes comfortable throughout Warrenton since we started out in 1946.

At Schraer Heating & Air Conditioning, we’ve been committed to professionalism and quality since we started our business in 1946. Our goal is to provide you with no less than expert heating and cooling services in Warrenton.

The company was founded as Scott-Woolf Incorporated when Gary Scott and Billy Woolf went into business in 1993.  They started with one stocked truck and a customer base of approximately 300 people.  In 1994,  they purchased Schraer Heating & Air Conditioning, which had begun operation in 1946 when Omar Schraer began building and installing furnaces.  His service area consisted of Warren and Montgomery County.  In the 1950’s, Mr. Schraer added air conditioning to the services he provided.  Gary and Billy have continued Schraer’s commitment to provide the most current innovations to their customer by adding high efficiency and Geothermal units to the product mix.  Schraer Heating and Air Conditioning’s goal is to provide loyal customers with expert heating and air conditioning services in Warren County and surrounding areas through professional commitment, quality workmanship and involvement in the community.

Today, Gary and Billy continue Omar’s commitment to providing the most current innovations to their customers, including high efficiency and geothermal systems. From fast repairs to convenient system replacement that fits your schedule, our goal is to provide you with the best customer experience you’ve ever had. This includes explaining our process from start to finish, so all your questions are answered, and paying attention to even the smallest details.

The Best Customer Service Experience I have ever had and I have been in the customer service business for 44 years. We recently purchased a cabin in Innsbrook and had a problem with the AC. Our real-estate agent recommended Schraer HVAC. They dispatched a technician within 48 hours and he fixed the problem immediately. Since it was a 40-year old unit we decided to replace it. They were able to schedule the replacement within a week and based on our schedule. At the last minute we had a family emergency and we had to coordinate the installation without us present. Needless to say, the install and communications were seamless. The level of communications, understanding, courtesy, respect, professionalism and friendliness of each of the members of the their team was outstanding! A Special Thanks to Dan (technician), Bill (pre-install manager), Julie and Michaela (office – a real joy to work with) and the two technicians (who I never met) who did a great job of installing and cleanup. We appreciate all of you!

I recently purchased a home in Warrenton, and had a problem with what I thought was my A/C. After the technician looked at it, he informed me that it was actually a fault with the heater. The technician was great with explaining the entire process from start to finish!

I will recommend them to everyone!“

I had a technician from Schraer do some HVAC work for me when I finished my basement and I was really pleased with the quality of the work and the attention to detail to do a really nice job. Professional and courteous too. I would go back for future needs!
