Lennox Commercial HVAC Repair in Denver
Independent service. Not affiliated with or authorized by Lennox.

What actually happens
- 01A person answers. Not a menu.
- 02Have the manufacturer, model and serial number ready — it's on the data plate.
- 03We ask what it's doing, what error is showing, and what service you still have to run.
- 04We dispatch with the parts that fail most on that platform.
- 05If the normal parts path stalls, we look for another one — donor units, substitutes, temporary capacity.
You called us because one thing broke. You can call RestauRun for the next thing too.
Refrigeration, HVAC, plumbing, electrical, hot side, cold side, doors, exhaust, fire, grease. One number. One company that owns the path back to uptime — whatever trade the problem crosses into.
We smell burning when the heat starts. Is that urgent?
Treat it as urgent. Shut the unit off at the thermostat and call. We'll inspect the heat section before you run it again.
Do you do preventive service too?
Yes, and in Denver it pays for itself. Coil cleaning, filters, belts and heat-section checks before the seasons turn.
