A Legacy of Comfort in Missouri

Reliable Heating & Cooling has been a cornerstone of comfort for residents in O’Fallon, Saint Peters, Lake Saint Louis, Wentzville, and Saint Charles, Missouri, for over three decades. Our journey began in 1990 when founder John Smith, a seasoned HVAC technician, decided to start his own company with a vision to provide top-notch heating and cooling services to his community.

Early Years and Growth

In the early days, Reliable Heating & Cooling operated out of John’s garage, focusing primarily on residential air conditioner repair and maintenance. As word spread about our exceptional service and attention to detail, demand grew rapidly. By 1995, we had expanded our team to include five technicians and moved into our first commercial office space.

Expanding Services and Reach

Throughout the late 1990s and early 2000s, we continued to grow our service offerings and geographical reach. We added the following services to our repertoire:

• Air Conditioning Installation
• HVAC Installation
• Comprehensive Air Conditioner Service
• Commercial HVAC Solutions

This expansion allowed us to serve a wider range of clients across the St. Louis metropolitan area, solidifying our reputation as a reliable and skilled HVAC company.

Embracing Technology and Innovation

As the HVAC industry evolved, so did Reliable Heating & Cooling. We’ve always been at the forefront of adopting new technologies and techniques to improve our services. In 2010, we introduced eco-friendly HVAC solutions and smart home integration to our offerings, catering to the growing demand for energy-efficient and technologically advanced systems.

Community Involvement and Recognition

Throughout our history, we’ve remained committed to giving back to the communities we serve. Our annual “Cool Homes for Heroes” program, launched in 2015, provides free AC repairs and installations to veterans and first responders in need.

Our dedication to excellence has not gone unnoticed. Reliable Heating & Cooling has received numerous accolades, including the “Best of St. Charles County” award for HVAC services for five consecutive years.

Looking to the Future

Today, Reliable Heating & Cooling continues to thrive under the leadership of John Smith’s daughter, Sarah, who took over as CEO in 2018. With a team of over 50 skilled technicians and support staff, we remain committed to our founding principles of quality, reliability, and customer satisfaction.

As we look to the future, we’re excited to continue serving our loyal customers in O’Fallon, Saint Peters, Lake Saint Louis, Wentzville, and Saint Charles, while also exploring new opportunities for growth and innovation in the HVAC industry.

From our humble beginnings to our current status as a leading HVAC provider in Missouri, the story of Reliable Heating & Cooling is one of perseverance, dedication, and a unwavering commitment to keeping our customers comfortable year-round.
