How does an Air Handler work?

 There are several types of heating and cooling equipment out there, but there is one that can be especially confusing depending on which place you live.

If you live in a place that has a humid climate and you don’t have a furnace then using an Air Handler is a common part of daily life. It’s simply the unit that works with your AC and heat pump to circulate conditioned air surrounding your home. And if you‘re living in a location with cool climates, it may confuse the air handlers with AC or furnace. 



Now let’s see how does an Air Handler work? 

What does an air handler do? To be precise, it manages the air. Basically. The air handler is the inner part of your AC system and crucial part at that. The work of the handler is to circulate the air across your home. The internal air handler consists of an air filter, coil and blower. The handler attracts air, transfer it over the col and it blows back into the home via the air duct system. 

An Air handler is a metal case containing two major components including:

  • An evaporator coil that circulates refrigerant from interior to exterior for conditioning the air.

  • The blowing fan that revolves accelerates the conditioned air across the home through ductwork. 

When it works in cooling mode, the air handler draws warm air from the home, blows it throughout the cold evaporator to reduce heat and then circulates the cold air across the ductwork. 

Then the retained hear moved to the external compressor where it is then dissolute and the cold refrigerant moves back to the evaporating coil for the next cycle. 

While in a heating mode, the air handler operates in a reversed way that acts as a heat pump, it attracts cool air from the home, circulates it throughout the warm evaporator coil then blows the hot air throughout. At the same time, cool refrigerant moves to the exterior heat pump that warms it up again using outdoor heat.

How efficient is an air Handler?

Efficiency is something that everyone prefers to discuss. For air handlers, the evaporating coil, the blowing fan and external unit all influences efficiency and performance. However, the harder your airhandler works, the higher your energy bills will be. So, how can you ensure that your air handlers work effectively? Look at the quick tips enlisted:

Ways to improve your air handler effectiveness:

  • Changing dirty filter:   A clogged or dirty air filter is one of the prime causes of reducing the efficiency with air handlers. As dirt gets clogged up, your handler fights to work hard to circulate air. Ensure you check the condition of air filter every month and change it. 

  • Update air filters system: Many filters limit airflow of the cooling system. This leads to similar types of issues that clogged filter causes. The best solution is to install an air clear as it eliminated pollutants from the air and does pressurise your air handler. 

  • Sealing of leakage: No matter whether it’s present in your air ducts or somewhere else across your home, air leakage has a huge influence on your energy bill consumption. So, the better idea is to seal the leakage to make it easy for the air handler to work.
