I have been working in the heating and cooling industry for many years.
While I do love all of my HVAC units, there are several HVAC units I have owned over the years that I simply did not like.
First there was the simple window air conditioner. I know, so many people have window air conditioners and love them, but they just aren’t for me. I really don’t like the amount of nice things they make. I also don’t like that a window air conditioner can only cool one or two rooms at a time, and they still cost me quite a bit. I prefer central air conditioning over a window air conditioner any day. The next HVAC unit that I didn’t particularly like was the gas boiler heating system. I could not believe how expensive it was to get a gas boiler installed, let alone the cost to just purchase the unit. To me there are just better ways to heat your home that are even more effective, and for this reason I was not a huge fan of the gas boiler heating system. The last HVAC unit that I have come to dislike is the portable space heater. While they can be useful for keeping your feet warm under a desk, overall I just think they are pretty useless. Over the years I have owned a few different types of portable space heaters, but I just think they are old fashioned and there are just better ways now to keep your feet warm. While I personally am not a fan of these HVAC units, they are still very useful to some people.
