Questions and Answers
My furnace pilot light keeps going out in my Commerce City home. What's usually the cause?
In our area, pilot light failures are often due to a dirty or faulty thermocouple, which is a safety device that senses the flame. Drafts, a weak flame, or issues with the gas supply valve are also common culprits. Our technicians can diagnose the exact problem, clean or replace the necessary components, and ensure your furnace operates safely and reliably.
How can I tell if I have leaky ducts reducing my heating efficiency?
Signs of leaky ductwork in Commerce City include uneven heating between rooms, excessive dust, unusually high energy bills, and your HVAC system running constantly to maintain temperature. We perform thorough duct inspections, often using specialized tools, to locate leaks at joints and in inaccessible areas like attics or crawlspaces, then provide a clear repair plan.
Can fixing duct leaks really make a big difference on my heating bill?
Absolutely. The Department of Energy states that the average home loses 20-30% of conditioned air through duct leaks. For Commerce City winters, sealing these leaks means your furnace doesn't have to work as hard or as long to heat your home, which directly translates to lower monthly energy costs and more consistent comfort throughout your house.
