My husband and I own a rowhouse with a basement apartment, which we rent out. One issue we face is that the house only has one HVAC system, so the thermostat is in our section of the house. If our tenants are too hot (which happens a lot), they text us to turn up the AC. Because of this we miss out on opening our windows on perfect fall days.
We would like to create two separate HVAC systems, especially because we are planning to move out and rent out the entire house next year. Do any of your readers have experience with this and can let us know about how much it cost? Also, any contractor recommendations?”
