Our Story
Built on 30+ years of St. Louis HVAC experience
Thomas Hoffmann founded Thomas Hoffmann Air Conditioning & Heating LLC with a simple goal: deliver honest, expert HVAC service to St. Louis homeowners and businesses — without the upsell, the corporate runaround, or the surprise pricing that has come to define the industry.
Tom is a Master HVAC Engineer with 30+ years of hands-on experience diagnosing, repairing, and replacing residential and light commercial heating and cooling systems. That depth shows up in every service call: faster diagnosis, more accurate repair options, and clear pricing before work begins.
We’re locally owned and operated from Des Peres, Missouri — a real local company answering real local calls. When something goes wrong with your heat or AC, you’re not routing through a national call center. You’re reaching the team that will be at your door.
More about our team and certifications coming soon. Until then, give us a call — we answer 24/7 for emergency heating and cooling.
