Why clients choose TrueNorth Heating & Cooling
Honest diagnosis first
Technicians find the real problem and explain it — the thing reviewers praise most.
Fix before replace
Marcus built the shop on one rule: diagnose, repair what works, replace only when it doesn't.
Fair pricing, no surprise
Quotes beat or match competitors; no hidden upsells or pressure to buy new equipment.
Solves the unsolved
Comfort problems other contractors couldn't crack — TrueNorth figures out why.
One visit, not three
Right diagnosis on the first call means one truck, one invoice, comfort restored.
How it works
A clear path from first call to handover
Pre-construction & planning
Before anyone picks up a tool, we lock the scope, the budget, and the schedule, pull and manage every permit, and order long-lead materials early so nothing stalls mid-build. You sign off on a fixed plan — not a guess.
Build-out
Your assigned lead runs the site daily and sequences in-house crews and vetted trade partners so the work flows in the right order, with the site kept clean, safe, and documented as we go.
Weekly updates
Every week you get a photo recap and a short written summary: what was completed, what's coming next, and where we stand against the schedule and budget — with plenty of time to weigh in on any decision.
Walkthrough & handover
We walk the space with you, build a punch-list together, and close every item before we call it done — then hand over a complete closeout package and a standing line to call afterward.

FAQ
Frequently asked questions
Do you charge for a diagnostic visit?
We quote the diagnostic fee up front and apply it toward the repair if you move forward. No surprise charges, ever.
Will you try to repair before recommending a replacement?
Always. We only recommend a new system when a repair isn't safe or cost-effective — and we'll show you the math either way.
Do you offer emergency service?
Yes. No-heat and no-cooling emergencies get same-day priority, including weekends and evenings.
