The main goals of an HVAC system are to offer thermal comfort and support the maintenance of acceptable indoor air quality through adequate ventilation and filtration. 

Today there are multiple options available both residential as well as commercial HVAC options to choose from. Here in this article, we will tell you the 10 essential HVAC facts.

1. Willis Carrier created the first air conditioner. But it wasn't until 1913 that an air conditioner was installed in a house for residential usage, at a mansion in Minneapolis, Minnesota, by Charles Gilbert Gates. However, the Romans invented the first heating system, the Hypocaust, which circulated heat from a furnace through pipes in the walls and the floor (starting at about 350 B.C.).

2. A well-insulated home is the most effective approach to reducing energy use without changing your heating system. By caulking window and door cracks, you can reduce your electricity bill by more than 25%. By keeping the air inside, your heating or cooling system spends less time adjusting the temperature of the room and more time preserving the environment.
3. By raising the thermostat, you may reduce your cooling costs while regulating the temperature and humidity when you're away. If nothing in your house poses a threat of overheating, turning off your system is OK.
4. The outdoor HVAC unit is an ideal place for waste such as grass clippings, twigs, and other falling leaves to accumulate. Every time you do yard work, clear away all the debris from the unit and the area surrounding it. If dirt starts to build up, rinse it down. 
5. Some thermostats are permanently connected to the house's electrical system. Some are powered by batteries. To avoid issues, change batteries at least once a year.
6. When utilization stays the same but energy use increases gradually or suddenly, it may indicate a problem with your HVAC system. To have the system checked, schedule a service call with your reliable heating and conditioning firm. Dirty filters, duct leaks, a lack of refrigerant, faulty components, or other problems could be at blame.
7. Running the heater when you don't need it wastes a lot of electricity, even on the lowest setting. When not at home, turn the device off; alternatively, add a programmed thermostat. A heating plan might make it simpler to decide when to use less energy; also, if your home is always heated, a lot of the heat will escape through unnoticed crevices.
8. A properly ventilated HVAC system aids in preventing allergens, mold, and germs from entering your home in addition to providing heating, cooling, and humidity control. Pollutant removal can enhance health, and living in a better interior environment is much more enjoyable.
9. You should choose the correct size of the HVAC system according to your room size. Incorrect size can lead to high electricity bills and malfunctioning of the system.
10. One of the more crucial HVAC facts to understand is that an AC failure is frequently caused by blown fuses, blown capacitors, tripped breakers, and damaged electrical cabling and connections, among other electrical components. The system can catch fire, shock, or electrocute someone who tampers with it. To resolve the issue, you should always speak with a specialist.
