This is partially because the homes are all so old they predate the existence of central Heating and Air Conditioning systems.
I have a circuit of thirty to forty farms that I visit once every month or so. It is not a locked-down, hard-and-fast schedule, because it requires a lot of travel plus there are a few other variables. I supply a specialized service for farmers plus ranchers, 1 that is truly affordable to them, plus yet pays me truly handsomely. With so many purchasers I don’t need to charge an arm plus a leg. I can be fair plus still do well for myself, and none of these guys can afford to spend our savings an Heating and Air Conditioning company to come to their farms more than once or twice a year. With our service I come by every 4 to numerous weeks to inspect their Heating and Air Conditioning systems plus do any heating repairs they may need. Rarely do I get called upon for air conditioner work, because the systems I service are for livestock, not for humans. In this area of the country it is truly proper to find rural homes that do not have a cooling system. This is partially because the homes are all so old they predate the existence of central Heating and Air Conditioning systems. Aside from a furnace in the basement, these houses often have no temperature control at all. The lifeblood of a farm or ranch is the livestock, so the barns plus corrals need to be outfitted with rudimentary oil furnaces to protect the animals in the winter. This makes up the bulk of our work load, because as you would imagine these furnaces take quite a beating from the livestock.
