About Comfortmate Bremen Service
A Second-Generation HVAC Company in Mokena
Comfortmate Bremen Service is a family-owned HVAC company backed by more than 40 years of industry experience. Today, second-generation owner Scott O'Sullivan continues the work his father, Jeff, started.
We provide heating and cooling service in Mokena, Tinley Park, and Orland Park.
From New Construction to Helping Homeowners Throughout Southern Chicagoland
Jeff O'Sullivan started Comfortmate Bremen Service after building decades of experience in HVAC. Early on, the company concentrated on new-construction projects. It later moved more heavily into residential heating and cooling.
Scott O'Sullivan now owns the business and represents its second generation.
Through those changes, one part of the company has remained steady. Comfortmate wants customers to understand their options rather than feel pushed toward a decision.
Why We’re Your Best Choice for HVAC Service
Family and Locally Owned
Because we’re local, our company is truly accountable to each customer. We also know how Southern Chicagoland’s weather affects your comfort.
Education Over Sales
At Comfortmate, we want you to walk away informed. That’s why we speak in terms you can understand and only recommend services you actually need.
Recognizable Technicians
All of our technicians arrive in wrapped trucks and in uniform. You’ll never have to guess about who you’re letting into your home in Tinley Park or Orland Park.
Pricing Built For You
We believe comfort should be accessible to everyone. That’s why we price our work at a flat-rate instead of on an hourly or commission basis.
Industry-Certified Excellence
We are certified as both an American Standard Comfort Care Dealer and a Mitsubishi Elite Diamond Contractor. This means we know our equipment.
What We Can Do For You
When your air conditioner stops cooling or your furnace will not run, our first job is to figure out why. We also provide maintenance designed to suit the needs of Southern Chicagoland.
If it turns out that replacement is the way forward, we’ll help you compare options and make the right decision. Our Mokena HVAC contractors can install everything from high-efficiency units to electric furnaces.
