You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular preventative maintenance is the best way to ensure trouble-free operation and peak performance. Yearly maintenance is required by Trane, Lennox, Carrier - in fact by ALL manufacturers to protect warranties. The Original Evans Air 3-Visit Maintenance protects you year-round. It can help to avoid a system failure in severe hot or cold weather when you need it most, and it can also keep your energy bill from getting out of control.
When Should I Do Maintenance?
The old adage is true: "an ounce of prevention is worth a pound of cure". Below you’ll find Evans' Preventative Maintenance Checklist, which is our proven method to keep your system in the pink and your home in constant comfort.
- All HVAC manufacturers require yearly maintenance to maintain standard warranties and extended warranties.
