In previous blogs, Del-Air has talked about the condenser unit, the vents, the fans, and even the ductwork making up your HVAC system. However, we have yet to discuss the ways in which the different parts of your HVAC system work together. Because the saying “the whole is more than the sum of its parts” is especially true in the HVAC world. It’s important to understand how the efficiency of one component affects all the others. Here are some of the key elements in your HVAC system along with the functions they perform:


One of the most important components of your HVAC system, the thermostat allows you to control the temperature of your home with the push of a button. Once you enter your desired temperature, the electrical sensor will compare it to the current temperature of the room and adjust the heat or AC accordingly. The blower can then spread the climate-controlled air around the room.


Another crucial HVAC component, the blower, pulls air in through the return ducts and then pushes conditioned air out through the supply ducts. Because a dirty air filter can affect the efficiency of the blower, it’s important that homeowners arrange to have their filters cleaned and changed regularly. Doing this will help prevent dirt from clogging your filter and preserve the life of your HVAC system.


Of course, the air the blower pushes out will eventually need to be conditioned again. Stale air from your home is drawn back in through the vents in the duct system. Along with cooling or warming the air to the desired temperature, your air filter will clean the air to remove dust and other particles. Homeowners can rest easy knowing that their family is breathing in clean, allergen-free air at all times.

Each part of the HVAC system plays an important role in keeping you cool and comfortable, which is why it is so important that homeowners sign up for a comprehensive professional maintenance program.

This was my first experience with Del-Air and they were prompt, professional, and knowledgeable. They were able to get me in on the same day for a maintenance visit, which I wasn’t expecting but very much appreciated. The office staff was pleasant and so was the technician that came out to service my air conditioners. Thanks…
