What You Should Know About Air Handlers
Often referred to as the “lungs” of your HVAC system, an air handler is a key component that helps circulate hot or cool air throughout your home. Along with maintaining a comfortable temperature, air handlers play a crucial role in improving your indoor air quality by filtering contaminants and expelling stale air outdoors.
Read on to learn more about the role of an air handler within your HVAC system, signs it’s time to upgrade the one in your home, and how to maximize its lifespan with preventative maintenance.
Understanding Air Handlers: What They Are and Their Role in HVAC Systems
The air handler is an indoor component of your HVAC system that works with your split-system air conditioner or heat pump to distribute air throughout the home. Often connected to existing ductwork, the air handler circulates conditioned air through each room. After the evaporator coil removes heat from the air, the air handler blower pushes it through the ducts to regulate the temperature of your Washington home.
Most air handlers contain seven main components that work together to keep your home at a comfortable temperature, including:
- A blower
- Evaporator coil
- Air filter
- Heating or cooling elements
- Dampers
- A control board
- A drain and condensate pan
The type of unit you have will determine which components it includes. Smaller units may only have an air filter, blower, and coil. These are called terminal units, blower coils, or fan coil units. A larger air handler, known as a makeup air unit (MAU), may have additional components, such as an advanced filtration system, to improve indoor air quality.
Is an Air Handler Right for Your Home?
If you are in the market for a new HVAC system, you wonder whether you need to purchase an air handler unit as well. A general rule for determining whether you require an air handler as part of your HVAC system is to look at the temperatures where you live.
If you live in a mild to hot climate, an air handler is often essential to help circulate cool air throughout your home. If you live in an area where temperatures fall below freezing and are considering a conventional furnace, you most likely will not need to install one. That said, homes with heat pumps will typically require an air handler regardless of the climate.
If you’re unsure whether your system requires an air handler, consult a reputable HVAC technician to determine if it’s the right choice.
Signs It’s Time for Air Handler Replacement
While air handlers typically last between 15 and 20 years, they sometimes fail early due to damage, improper installation, or lack of maintenance. Knowing the signs of a failing air handler helps you get ahead of the issue to prevent complete system breakdown or damage to other components.
If you notice any of the following, it may be time to upgrade your air handler:
- It freezes frequently: If your air conditioner constantly freezes during the summer, this can be a sign of poor airflow, low refrigerant levels, or mechanical failure caused by a dying air handler.
- Inadequate airflow: If you notice that your unit can no longer produce enough air to keep your home at a comfortable temperature, it may be due to holes or cracks in your air handler that require replacement.
- It constantly requires repair: If your air handler is the frequent cause of your AC or heat pump troubles, replacing the system is likely a cost-effective alternative to constant repairs.
- Your energy bills are rising: A failing HVAC system uses more energy to heat or cool your home. If your energy bills are suddenly spiking without reason, contact an HVAC technician to determine if your air handler could be the culprit.
Preventative Maintenance Guide for Air Handlers
The best way to help your air handler reach its maximum lifespan is to schedule annual maintenance with a trusted HVAC company. During the appointment, a technician will thoroughly inspect, clean, and tune up your system to keep it running in top condition. If they notice the need for minor repairs, they’ll quickly fix them to prevent the issue from progressing.
In addition to professional maintenance, there are some steps you can take at home to keep your air handler working at peak performance, including:
- Changing the air filter every one to three months
- Keeping the surrounding area clear
- Performing regular visual inspections to check for damage
- Using ceiling fans to circulate air and reduce the air handler load
- Cleaning the air handler to prevent buildup of dirt and debris
