 # Maintenance plans that keep small problems small

Most breakdowns start as something a technician could have caught at a tune-up. Our plans put spring and fall visits on the calendar so you don't have to remember — and your system gets a check-up from a NATE-certified technician before the season that tests it most.

 ## What happens at each visit

Twice a year, a NATE-certified technician cleans and checks your heating and cooling system and changes your filter. With Whole Home, a licensed plumber also visits once a year — usually in summer — to check for leaks, dye-test your toilets and look over your water heater and the plumbing in accessible areas like your crawl space.

If anything needs attention, you'll hear about it before it turns into a breakdown — with a firm price and no pressure.

 ## A few common questions.

### What does a plan cover — and what's extra?

Plans cover your scheduled tune-ups and inspections. If your technician finds something that needs repair, they'll show you and give you a firm price before doing anything. Water-heater flushing is quoted separately.



### Can I sign up if something is already wrong?

Yes. Tell us what's going on when you call, and we'll schedule a repair visit first so your system is running right before your plan starts.



### Are generators and commercial systems included?

Not in these plans. As a Generac dealer, we offer separate generator maintenance, and we set up commercial maintenance agreements based on your equipment. Ask our team for details.



### Does a maintenance plan replace my manufacturer warranty?

No. Your warranty and your plan are separate. But manufacturers like Trane recommend regular professional maintenance, and your plan gives you a dated service record every spring and fall — useful if you ever need to make a warranty claim.
