How Does An Air Handler Work?

You may have heard of an air handler when referring to an HVAC system but are confused about what its main function is. That is where we at Absolute Comfort Air are here to assist you! This blog is dedicated to answering your questions and leading you on the right path to figuring out what is best for your home!

Air Handler Defined

An air handler is usually stored inside the home and assists in moving cool or warm air through the ducts and within your home. The outside unit, or “air condenser” is what creates the warm or cool air. A unique quality about these systems is that they may run at different capacities based on the size of your home and the climate you live in.

Benefits Of An Air Handler


You may hear your outside AC unit kick on and off as it generates cool or warm air, but chances are you will not hear your air handler inside as it pushes air to your vents. The system operates at a lower, energy-efficient speed. Think of your air handler like a stealthy ninja doing its job in near silence.


The beauty of the air handler is its ability to meet your preferences down to a degree. Despite working for longer periods, they can work at lower levels of energy. This makes for an extremely energy-efficient system that may save you a ton of money. Homeowners should always follow energy usage guidelines depending on the time of year. Be aware of peak running times when your HVAC unit will be working harder and adjust your thermostat accordingly.

Enhanced Air Quality

Longer running cycles provide more clean air circulating through your home. Meaning more air passing through filters will cause an increase in purified air. The air handler, especially paired with an IAQ system, ensures a healthy hygienic environment for you to breathe in!

Less Humidity

The frequent rush of cool air is a huge assistant when battling humidity. This lengthy process of cooling within the home will further eliminate the moisture in the air. This will assist in controlling the humidity within your home. Homeowners dealing with warm temperatures will love this benefit!


The constant turning on and off of the standard unit places a lot of tension on the system. This can lead the system to wear out and break down quite often.

However, the air handler avoids this issue by running at various capacities but frequently operating at lower energy levels. Think of your unit like a long-distance runner. They pace themselves and can run for extended periods and remain durable.

Air Handler Installation & Maintenance

Initial Installation Cost

The initial cost of your handler installation will depend on the size of your system. You will need measurements from a professional to assist in determining the price. However, our experts can help you with that!

Frequent Filter Changes

Considering the increased work rate of the air handler, it runs through filters at a much higher rate. This means you will be required to switch out the filters quite often, about every one to three months depending on your usage rate. The air filters themselves will not be that costly, and you can replace them yourself or give our team a call.

Precise Sizing Requirements

For the system to run at its peak efficiency it needs to be sized precisely for your home. This of course is a more extensive process for professionals. If the unit is not sized properly not only could this lead to reinstallation, but also an elimination of the benefits that come with this type of system.

What Our Customers Have To Say

Had Us Up and Running in a Couple of Hours

Tanner was our service tech. Our heat quit on a Friday night and I called Absolute Comfort Air on Saturday morning. Tanner came to our home about an hour and a half after my phone call and diagnose the problem, explained the circumstances, and gave me a detailed quote. He then proceeded to make the repair.  He worked steadily and had us up and running in a couple of hours. Tanner was very polite, explained things in detail, and answered my questions very patiently. Thank you for a job well done.

I’ve been without heat since Saturday when my heat pump went out. I called Absolute Comfort and Alex came out and confirmed that after 19 years it had died. Kevin came out yesterday morning and he and Mark came this morning to check on things. Wayne and D.J. installed my new system. My house is warmer than it’s been in years and I wanted to thank you all for the fast, courteous and efficient manner you took care of my problem. Y’all are simply the best!!

I had a service technician by the name of Tanner visit my house today and go through a check list of all the components of my HVAC and found everything to be good and working at it’s best.
