Is your boiler not working quite right, making strange noises, or has it stopped working entirely? Diagnosing and repairing boilers takes special expertise. Trust our reliable and professional boiler technicians to find and fix the problem fast.

Emergency Boiler Repair

If your boiler goes out on a freezing cold day, we offer 24/7/365 emergency service. With two locations to reach you fast and local customer service, we’re here when you need us.

Boiler Repair Process

  1. Schedule the Repair – Use this form or call us at (815) 455-7000 to request a repair. You'll speak to a friendly Customer Service Rep to find a convenient time that works with your schedule. We offer a 2 hour time window for our customers in the suburbs and a 3 hour time window in the City.
  2. We'll Call You On the Way – We understand that you're busy. Don’t wait at home. Our dispatchers will call you when our technician actually is on his or her way to your home.
  3. We Start With a Thorough Evaluation – Our expertly trained technicians begin with a thorough evaluation of your equipment. We’ll diagnose the immediate problem but also examine the entire system to determine if there are any underlying issues or potential hazards.
  4. Prices Are Always Quoted Upfront – Once the diagnosis is complete, our technician will prepare a prioritized list of recommendations and pricing. All recommendations are explained so that you understand exactly what the problem is and how much it’s going to cost. We never perform any repairs without first getting your approval.
  1. Get Your Air Boiler Repaired Same Day – In most cases, your technician can get the part needed from our fully stocked trucks or a nearby warehouse. Our goal is to get your boiler fixed that day.
  2. Walk Through of Work Performed – Once complete, our technician will again walk you through all the work performed and recommendations he has moving forward. You will be left with a detailed service ticket describing work performed and associated billing.
  3. Let Us Know How We Did – What you think is important to us. You can be sure that we’ll use your valuable feedback in our ongoing goal to provide the best possible service.
