A S Mechanical | Experienced HVAC Services in Denver, CO

We often repair pilot light issues, which are common in Denver's older homes. It can be caused by a dirty thermocouple, a draft, or a faulty gas valve. Our technicians will diagnose the root cause first. If the furnace is very old and inefficient, we may recommend a replacement to improve reliability and lower your energy bills, but we always prioritize the most cost-effective repair for you.

Denver's sun exposure and temperature swings can cause thermostats to be improperly calibrated or placed in a poor location (like near a vent or window). We can recalibrate your existing thermostat, relocate it to a more neutral spot, or install a new, more accurate smart thermostat. Proper calibration is key to comfort and efficiency in our climate.

Correct sizing is critical in Denver to handle both hot summers and cold winters. We perform a detailed Manual J load calculation, which factors in your home's square footage, insulation, window placement, and local weather data. Installing a properly sized system prevents short-cycling, uneven temperatures, and high energy costs, ensuring reliable performance year-round.
