FAQs
How often should my furnace be inspected to prevent carbon monoxide risks in my Cortland home?
For safety, we recommend an annual furnace inspection and tune-up, ideally before each heating season. This proactive check includes testing for carbon monoxide leaks, ensuring proper venting, and cleaning components. Regular maintenance is the best defense against the silent danger of CO, especially with older systems common in our area.
My smart thermostat isn't working correctly with my HVAC system. Can Dennis Heating and Cooling help?
Absolutely. Improper wiring or compatibility issues between smart thermostats and older HVAC systems are common. Our technicians are certified to diagnose and resolve these problems, ensuring your thermostat communicates properly with your furnace and air conditioner for optimal efficiency and comfort in your home.
What are the signs that my furnace might be producing carbon monoxide?
Key warning signs include a yellow burner flame (instead of blue), excessive soot or rust around the furnace, a persistent stale or burning odor, and symptoms like headaches or nausea in household members that improve when away from home. If you notice any of these, shut off the furnace, ventilate your home, and call us immediately for a safety inspection.
