You always hear all sorts of talk about commercial heating plus a/cs as well as residential heating plus a/cs! What a lot of people that do not recognize a lot about heating plus cooling don’t realise is that the most respected central heating plus a/c program is a residential heating plus a/c; A commercial heating plus a/c program are those sizable monster Heating, Ventilation, plus A/C units that are used to heat plus cool commercial corporation buildings, they can also come in the form of rooftop Heating, Ventilation, plus A/C systems.
You know..those central heating plus a/c program units that you sometimes see kneeling on the roof of immense buildings! Residential heating plus a/cs are what you have in your home, then so don’t let people confuse you when they start rambling on about all these weird styles of central heating plus a/cs, then if someone asks you what kind of a central heating plus a/c program you have, you would just simply tell them it is a residential central heating plus a/c program unit, then plain plus straight-forward! Of course if you are rich you may have a zoned heating plus a/c! But usually most respected folks will not have those zoned heating plus a/cs that heat plus cool at weird rapidly changing temperatures inside your house.
I assume I may recognize only a single guy who genuinely has a zoned heating plus a/c program unit. So don’t let people confuse you if they ask if you have Heating, Ventilation, plus A/C zone control.
