The air conditioning unit is one of the most important components of your HVAC system and here are some facts that you probably did not know.
Turning off your AC for a long period will cause it to work harder the moment you turn it on. Therefore, when you're going on a vacation for a week or two, you can leave your AC on. However, make sure that it is networked with a programmable thermostat set to a low temperature that shuts if off and turns it on when necessary.
The ducts play a huge role in maintaining the cool in your home. These are the conduits that run throughout the house within the ceiling, which convey the cold air produced by your AC. If they are made of metal, chances are the cool will be absorbed and transferred through the ducts rather than into the house. Thus, you need them wrapped with insulation.
An old filter that has accumulated dust and grime does not only block cool air from being blown into your house, but also can cause respiratory illnesses. One clue that you need to replace your AC filter is when the members of your family start coughing. Dust and other harmful particles are now mixed with the air.
