Heating and cooling systems have a way of breaking down when the weather is at its worst.

It can happen during the coldest day of a fridged winter, or during a sizzling heat wave. That's often because that's when your comfort system must work the hardest... and when you need it the most.

Of course, we're always here for emergency service when you need it. However regular check-ups may help prevent problems and will maximize the life expectancy of your system. That's why we encourage our customers to invest in Thornton's Guardian Protection Program.
