Gas Furnaces | Trane Furnaces

Today’s new high-efficiency gas furnaces can save up to 50 percent in operating costs over a ten-year-old furnace. Many older model furnaces have an industry rating of only 65 percent, and some are rated lower.

Thornton Heating Services is proud to offer a line of high-efficiency Trane gas furnaces rated at 80 percent and 90 percent, with some model rates as high as 96.6 percent. Depending on your average usage, higher-rated furnaces can significantly reduce your gas bill.

Gas Furnaces Service – Furnace Repair

We offer many furnaces with variable and multi-speed features that can enhance indoor comfort by slowly ramping up to your thermostat setting rather than simply turning it on at full speed. This alleviates the “cold air blow” often associated with single speed furnaces and dramatically reduces system noise.

We’d be happy to take you through our selection of industry-leading furnaces for your home. Call the NATE certified professionals at 847-905-1608.
