Allow tenant to suspend gas service in summer?

[John A.]

I haven't posted a question in quite some time so here goes.

Situation: SFH located in AZ. Water heater, stove, clothes dryer are electric. Only thing using gas is the furnace for heat in the winter months. Furnace is unplugged when evaporative cooler is connected.

Question:  Tenant wants to stop paying the notional monthly gas bill (about $15-20) in the summer months by telling the gas company to discontinue service.  He'd rather just pay the reconnection fee (about $60-70) every November when he needs heat.  If you were the landlord, would you let him do it?  What's the down side of his plan?

Thanks,

John
