How to categorize regular monthly maintenance?

What category do I select for monthly plumbing or hvac services from a vendor? It is a set monthly payment that is setup like to avoid costly repairs

@marceldcosta This sounds like regular maintenance, so I would think “Repairs & Maintenance > HVAC Repairs.” Preventative maintenances is still maintenance. I would suggest also checking with a CPA and/or seeing what others here in the forum have to say.
