"Wow!! On Time exceeded my high expectations. He communicated the problems, started with low-cost repairs first and talked me through options. My 22-year-old unit has a new life!"

Indoor air quality in Lakewood faces challenges unique to Colorado's high plains. The dry climate (humidity often drops below 15% in winter) causes respiratory irritation, static electricity, and cracking of wood floors and furnishings. Wildfire smoke from June through September can push outdoor air quality to unhealthy levels — without proper filtration, that smoke enters your home through your HVAC system. We install whole-home humidifiers ($400-$800), air purification systems, UV germicidal lights for ductwork, and MERV-13+ filtration upgrades.
Lakewood stretches from the plains to the foothills, with elevation differences of 500+ feet across the city. Homes in the Green Mountain area sit at 5,800+ feet and need more aggressive heating settings than homes in eastern Lakewood near the Federal Center.
Our technicians serve all Lakewood neighborhoods including Green Mountain, Belmar, Union Square, Bear Creek, Applewood. Whether you're in a newer development or an established neighborhood, we have the expertise and licensing to handle your HVAC needs.
