HVAC in Denver, CO

Denver's mile-high altitude and 300+ days of sunshine create a unique HVAC environment. The thin air affects combustion efficiency in furnaces, and dramatic temperature swings — it can be 70°F and snowing within 24 hours — stress heating and cooling systems equally.

Local Insight

At 5,280 feet, Denver furnaces must be altitude-adjusted for proper combustion. Local techs calibrate gas pressure and verify heat exchanger performance at elevation — a step lowland contractors don't know to perform.

Seasonal Tip

Denver's spring is the most unpredictable season — you may need AC one day and heat the next. Have both systems inspected by April to avoid being caught off guard.

4 Listen for a hissing sound near the unit
