About us
Northline Heating & Air
Northline Heating & Air designs, installs and services heating and cooling systems across Denver, CO.
We started as a two-truck operation doing service calls, and we still treat every install like it has to last fifteen summers. That means measuring the house before quoting equipment, and testing the duct system instead of guessing at it.
Our technicians are on salary, not commission. Nobody at Northline Heating & Air earns more by selling you a system you do not need.
