HVAC and AC demands
I have a single-family property that had been rented out for 4 years without any significant complaints. I just moved in new tenants, and I was quickly told that the AC is not cooling. I immediately had my HVAC tech inspect the unit and he said the AC unit is working properly. Upon further discussion, my new tenants want the temperature to be between 70-72 degrees. My previous tenants only set the thermostat to 75-76 which the unit can easily handle. Currently it is mid-summer with outdoor temperatures in the 95–100 degree range. The AC unit is 13 years old, and my hvac tech does not think it could cool the house to 70-72 degrees during the day. But also reassures me that he has thoroughly inspected it and nothing is faulty.
As the property owner, what is my obligation? The tenant is currently setting the thermostat to 70 degrees, but the AC unit is only getting the temperature down to 74 degrees. So, it is cooling the house, just not to the tenant's satisfaction and it likely will not be capable of doing so.
