There is this family owned bakery in town that is absolutely fabulous. They have the best cakes and cookies around. Also, the place is a sort of diner as well where people can have coffee and cake, etc. It’s really great to eat in there because they always have the temperatures and the air quality perfect. They have some kind of air purification system going on that really makes the air nice. Even with all the baking going on in there, the indoor air quality never seems to fail. Even the central heating and air conditioning system is always on top of it so to speak. If the central air conditioning is on it is the perfect temperature. Never too cold or never too stuffy. And with the central heating system it is pretty much the same thing. You can go into this bakery all year round without a care in the world. You never will have to worry about experiencing bad temperatures or bad air quality. It is just a given that both the central heating and air conditioning system as well as the air quality will be perfect no matter what. I have often inquired to the owners about their secret to the air quality. And they have told me that it is just your standard air purification system that runs throughout the place. And for the central heating and air conditioning system they just always keep up on it and make sure that they get their HVAC tune ups and check ups every few months. This is what keeps the central heating and air conditioning system working properly in there.
