Thornton Heating Service, Inc. Guardian Home Comfort Protection Program is a Smart Choice

Heating and cooling systems have a way of breaking down when the weather is at its worst. It can happen on the coldest day of winter or during a sizzling heatwave. That’s often because this is when your comfort system is working the hardest and when you need it the most. We’re always here for emergency service, however regular check-ups maximize the life expectancy of your equipment. That’s why we encourage our customers to invest in our Guardian Home Comfort Protection Program. One of the many benefits of this program is that on new equipment installed by Thornton Heating Service, Inc. our labor warranty will match your equipment’s part warranty as long as you remain a part of the Guardian Home Comfort Protection program. Save money, ensure comfort, and reap the benefits!
