Some people believe that HVAC is a luxury.
In other words, they think that depending on where you live you do not necessarily need heating and cooling systems in your house.
I find this to be untrue. At least in this country. I have traveled outside of the country and I have discovered that there are millions of people who do not have heating and cooling systems and their homes. Nonetheless, I do believe that here in our country HVAC is important no matter where you live. If you live in the south, you definitely need your air conditioning. I use my AC all year long. Most of the time, I have very little use for the heater, although this year our winter has been quite cold, So I am using the heater just about every day. In fact, I have set my heating thermostat higher than I normally do. Generally speaking, I do not like a forced air heating system with a very dry heat. It feels artificial to me, and it causes me some kinds of problems such as chapped lips, dry skin, and painful sinuses. Anyway, even farther south where my daughter lives, people are using their heaters this year. I do not know if climate change is real or not, but we definitely need our heaters this winter, and I definitely would not have survived this past summer without my air conditioning. HVAC is important no matter where you live.
