FAQs
What are the most common signs my gas furnace needs repair?
Watch for uneven heating, strange noises (rumbling, squealing, or banging), a yellow or flickering burner flame, frequent cycling on and off, higher-than-normal utility bills, or the smell of gas. If you notice any of these symptoms in your Erwin home, turn the system off and call our certified technicians right away to avoid safety hazards and costly breakdowns.
How often should I schedule professional maintenance for my gas furnace in Erwin?
We recommend a tune-up once a year, ideally in early fall before the heating season begins. Regular maintenance includes cleaning burners, checking heat exchangers, inspecting safety controls, and calibrating the thermostat. Annual service keeps your furnace operating safely, maximizes efficiency, extends equipment life, and helps maintain valid manufacturer warranties.
What should I do if my furnace stops working outside regular business hours?
First, double-check that the thermostat is set to "Heat" and the temperature is above the current room reading. Make sure the furnace switch and breaker are on, and inspect/replace the air filter if it’s clogged. If the system still won’t start or you smell gas, shut it off immediately and contact our 24/7 emergency repair line. Our on-call team can usually arrive anywhere in Erwin within an hour, even on weekends and holidays.
Are your technicians qualified to work on all furnace and HVAC brands?
Yes. Our NATE-certified and factory-trained technicians receive continuous education on the latest gas furnaces, heat pumps, and dual-fuel systems from leading manufacturers such as Trane, Carrier, Rheem, Lennox, Goodman, and more. We carry fully stocked service vehicles, so most repairs can be completed on the first visit regardless of your unit’s brand or model year.
How can I improve the energy efficiency of my gas furnace and reduce heating costs?
Replace or clean the air filter every 30–90 days, seal duct leaks, keep supply and return vents clear, and install a programmable or smart thermostat to lower the setpoint when you’re asleep or away. Annual professional maintenance will also optimize combustion efficiency, identify worn parts early, and ensure proper airflow. If your furnace is more than 15 years old, consider upgrading to a high-efficiency (AFUE 90%+) model paired with a modern AC or heat pump for maximum savings in Erwin’s mixed climate.

There is a flat diagnostic fee that covers travel and a comprehensive system evaluation.
