Denver, CO
Heating in Denver: what's different
Heating work in Denver follows the local climate. Heating is the main load in cold climates. Furnaces and boilers run for months, so ignition, venting, heat exchanger and carbon monoxide checks before winter are important.
A common Denver pattern: altitude setup. Furnaces need high-altitude adjustments for safe combustion. Another: dry air. Humidifiers are popular in winter.
The heating services Denver homeowners ask for most are furnace Repair. No heat, ignition failure, short cycling and pilot or flame sensor problems.
Denver's Community Planning and Development department issues mechanical permits and requires licensed contractors. Schedule furnace service in early fall and AC service in spring. Hail season peaks from May through August, so check outdoor units after storms.
