While air conditioning doesn't technically fall within the state's “habitable guidelines”, providing a fully functioning heater does. In cities like Sacramento, winter temperatures don't usually drop below 50 degrees. So, in the beginning, air conditioning consisted of cleaning the air, which already included temperature control. However, the meaning changed over time to refer to any temperature control, but usually to the cooling of hot air.
It also moved from an industrial environment to a more personal one. As for your home's climate control system, you can use gas for the boiler during the winter. However, many homes in the Tucson area have heat pumps. In fact, they don't actually generate heat at all.
Instead, they work by extracting warmer air from outside and transferring it inside during the winter. In summer, this process is reversed. The heated air is removed from the interior of the house and is expelled to the outside. The short answer to this is: “yes”.Yes, you can add an air conditioner to a forced air heating system.
However, it's a complex process and we never recommend that a landlord try it. Of course, we will say this about any air conditioning or heating installation. There are many factors that influence the adaptation of the correct system to the right size of the house, for example.
