An ounce of prevention is worth a pound of cure
Regular maintenance extends equipment life, keeps efficiency high and helps you avoid breakdowns in the worst weather.
2,500 hours a year = 100,000 miles
You wouldn’t drive your car 100,000 miles without changing the oil. The average heating and air system runs about 2,500 hours a year — the equivalent of 100,000 miles. Yet most homeowners skip service, leading to high utility bills, costly breakdowns, poor comfort and potential safety issues.
Pre-season maintenance helps avoid failures in severe heat or cold — exactly when you need your system most — and keeps energy bills under control.
