Maintenance starts with the equipment you have and how it is operating. The appropriate service scope is confirmed around the system and property involved.

  3. 3

FAQ

Maintenance questions

What does a maintenance visit include?

The appropriate maintenance scope depends on the equipment and property. Share the system types, number of units, last service date if known, and any current concerns. The service scope and estimate are confirmed before work proceeds, rather than assuming the same checklist fits every system.

Should I request maintenance if the system is already malfunctioning?

Describe the active problem clearly rather than only asking for routine maintenance. A system that is not heating or cooling, cycling unexpectedly, or displaying an error may need diagnostics before the maintenance scope can be settled.

Can I plan maintenance for more than one system?

Yes. Share the number and types of systems and the areas they serve. The property service plans offer preventive maintenance options for multi-system properties, with final pricing and scope following an equipment survey.

Does a maintenance request enroll me in a service plan?

No. You can request routine service or ask about a plan without enrolling. Standard Preventive Maintenance and PM + Minor Component Coverage can be compared separately, and any plan scope and terms need to be confirmed before enrollment.
