Having an issue with tenant not keeping up with oil for the heat

[Lee Underhill]

This is our first rental property and having an issue with the one tenant keeping oil in the tank . They call us to say the furnace is not working but then we find out it’s because once again he has run it to low and wants someone to come out to look at it when we already know the issue is the low oil ? Do we have the right to charge the tenant the fee for a service call since it’s their responsibility to keep up with the oil?
