About Agers Heating & Air Conditioning

Why You Should Work with Our Chesterfield HVAC Technicians

At Agers Heating & Air Conditioning, we believe the most successful companies are the ones that appreciate their customers. Let’s face it: HVAC companies don’t have a great reputation because so many of them encourage their employees to oversell. Brian Agers, the founder of our company, experienced just that kind of dishonesty while he was working for others when he first started working in the HVAC industry.

Disenchanted, Brian quit his job and started his own company in 2004. His intention was to build an honest, reliable business built on employees with the right skills, knowledge, and integrity to carry out your HVAC needs.

Since Agers Heating & Air Conditioning began, we have grown to over 4,000 loyal customers across the Greater St. Louis area. And we have only been able to achieve this success by being fair with people and focusing on customer service. Our employees are trained, equipped, and ready to help you with all your heating and air conditioning needs.

Well Trained

No one at our company is a salesman. Our service technicians have at least 15 years of HVAC field experience and are properly trained. To stay on top of our developing industry, our employees participate in ongoing continuing education. This experience allows us to help our customers make informed decisions about their heating, air conditioning, and ventilation.

Well Equipped

Our diagnostic tools and gauges are the highest quality tools available. They allow us to know exactly what’s happening internally with your air conditioner so there’s no guesswork involved. In addition, every employee has their own iPad and iPhone to streamline diagnosis, quotes, and scheduling with customers.

Well Presented

First (and last) impressions are important. That’s why we insist that our employees maintain a clean and professional appearance and communication to match our professional expertise. Our focus is on educating our customers. We’ll discuss everything from equipment features to unit efficiency in layman’s terms, so you understand exactly what you’re getting from us.

Well Informed

Our customers get text and/or email messages when they book an appointment, a reminder the day before, and when our technician as on the way to their home or business. They also get an opportunity to review us and tell us about their experience with Agers. We want your satisfaction to be 100%. Let us know if you have any questions or concerns with any part of your interactions with us.
