A Small HVAC Company Built on a Decision Most Contractors Wouldn't Have Made

Owner-operated, repair-first, and honest about pricing — since the day JDT started.

Why I Started JDT Heating and Cooling

Early in my career, working for a larger HVAC company, I was sent to a home to assess a system for an elderly couple. When I looked at it, the problem was clear — a straightforward repair, nothing more. But the job I was expected to sell was a full system replacement. Around $10,000.


I fixed the repair instead. Charged them what it actually cost. And walked away knowing I couldn't keep doing work that way.


That job is the reason JDT Heating and Cooling exists. I started this company because I wanted to run jobs the way I believed they should be run: find the real problem, fix it if we can, charge a fair price, and tell the truth if a replacement is ever actually warranted. That's not a marketing line. It's the thing that got me out of a system I didn't believe in.


Every job I take on is still priced and handled the same way.

What Owner-Operated Actually Means on the Job

Owner-operated doesn't just mean one person's name is on the business. It means the standard of work is personal. There's no layer of management between the customer and the person accountable for the job. When something isn't right, you call the same number you always call — and it gets addressed.



JDT is a small operation by design. That keeps overhead low, pricing honest, and accountability direct. You're not a route stop in a dispatch queue. Every job is handled with the understanding that the reputation of the business rides on it.

Licensed, Insured, and Straightforward

JDT Heating and Cooling is fully licensed and insured to perform HVAC work in Illinois. I'll tell you my license number if you ask — there's no reason to keep that behind a form. We carry full liability coverage, and I'll put that in writing if a job requires it.


  • Illinois HVAC License: [license-number — confirm before launch]
  • Fully insured: general liability and [workers' comp or additional coverage — confirm]
  • [BBB standing or trade association memberships — add if applicable]
  • Military discounts available — call to confirm current terms


If you're vetting contractors and want to verify credentials before booking, that's exactly the right thing to do. Call me and I'll walk you through it.

Honest Pricing — Not Because We're Cheap, But Because We're Fair

One of the most common things new customers say after a first job is that they didn't expect the price to be this straightforward. No diagnostic fee layered onto a repair quote. No parts markup that doubles the invoice. No pressure to upgrade while we're already in your home.


A capacitor replacement — one of the most common AC repairs — runs about $150 at JDT. At larger regional chains, that same part and labor routinely runs $400 to $500. The difference isn't quality. It's the overhead of a high-volume operation built around upselling.


We're a local HVAC contractor serving the northwest suburbs. The work gets priced for what it actually costs to do it right.
