I was surprised when my tenants called and said that the air conditioner was not working in their apartment. They had just moved in and I had inspected everything. I had also had the heater and air conditioner serviced just days before the move in. I always have the heating and air conditioner checked before I rented out to new tenants. I’m still well aware that life doesn’t always work as planned so I called up my usual air conditioning company to go take a look at the tenants air conditioner. Then I prayed that the repair bill would not be too expensive. Thankfully, it wasn’t expensive at all. In fact, it fit into my regular maintenance plan and I didn’t have to pay anything. I did have a laugh though when the air conditioning technician told me what the problem had been. He said there was nothing wrong with the air conditioning system at all. My new tenants we’re not aware that they had to turn the thermostat setting to the cool side in order to work. He said that the thermostat was set to fan and that the tenants thought that it would turn on the heater or air conditioner to keep it whatever temperature they wanted. I didn’t know people could be that stupid. The technician and I had a good laugh about this. Next time I take on new renters, I’m going to make sure to run through how the heater and air conditioner work before I leave the premises. I don’t have a lot of free HVAC services left this year. I can’t afford to throw them away on stupid calls like this.
