Lewisville FAQ

Should I wait until my furnace completely fails before calling for repair?+

No. Catching these signs early is usually a smaller, more straightforward repair than waiting for a full breakdown, especially since a complete failure tends to happen at the least convenient time, during the coldest stretch of the season.

Is a yellow pilot light always a carbon monoxide risk?+

Not necessarily automatically dangerous in every case, but it does indicate incomplete combustion, which is worth having checked promptly given the carbon monoxide considerations involved with any gas furnace issue.

Do you see this issue often in Lewisville?+

It comes up regularly across our Lewisville service calls, alongside the rest of Lewisville ISD. Call (817) 935-8540 if you'd like us to take a look at your specific system.
