Pro Tips for Homeowners
Change your filter before the first cold snap every fall — a clogged filter causes heating systems to overheat and shut down on safety limit switches.
If your gas furnace clicks repeatedly without igniting, check the filter first. Restricted airflow overheats the system and trips the high-limit switch.
Keep 2 feet of clearance around your outdoor heat pump unit — snow, ice, and debris around the unit prevent the defrost cycle from working properly.
If you smell something burning when the heat first turns on in the fall, it's usually just dust burning off the heat exchanger — normal and it fades quickly. Persistent burning smell is not normal; call us.

FAQ
Common Questions
Is it worth repairing an older furnace?
A useful rule: if repair cost × age-in-years exceeds $5,000, replacement is usually the better financial decision. A furnace older than 15–18 years with a major repair is often a strong replacement candidate. We'll give you honest numbers for both options.
Do you service gas furnaces?
Yes. We service and repair gas and electric furnaces, heat pumps, dual-fuel systems, and all brands of residential heating equipment across Surry, Wilkes, Yadkin, Ashe, and Alleghany County.
What should I do if I smell gas?
Leave the house immediately. Don't use any switches, phones, or appliances inside. Don't start or stop your car in the garage. Call your gas company from outside, then call us. Do not re-enter until the gas company says it's safe.
My furnace keeps cycling off — what's causing it?
The most common causes are: a dirty air filter (triggers the high-limit safety switch), a faulty flame sensor (furnace lights but immediately shuts off), or an overheating heat exchanger. Check the filter first. If it's clean and the problem continues, call us — flame sensor issues are a quick fix.
How long does a furnace last?
Gas furnaces typically last 15–20 years with annual maintenance. Heat pumps last 12–15 years. An older system that's getting repaired every season is usually past its cost-effective life. We'll tell you honestly when you're at that point.
Is carbon monoxide from a furnace dangerous?
Yes — CO is colorless, odorless, and potentially fatal. A cracked heat exchanger is the most common HVAC source of CO in homes. Have your furnace inspected annually, ensure CO detectors are working and within their service life (5–7 years), and call us immediately if an alarm triggers.
