Caption: What is an air handler
Imagine if your home's comfort was being delivered to you just like a package from FedEx. Well, that's exactly what air handlers do! They play a vital role in keeping your indoor temperature comfortable all year long. In this comprehensive guide, we'll explore the ins and outs of air handlers, their components, and why they are crucial for your HVAC system's efficiency and your overall indoor comfort.
The PB&J of HVAC
When you have a heat pump system, an air handler becomes a principal indoor component. It works hand in hand with the outdoor unit to efficiently circulate conditioned air throughout your home. Proper matching of the air handler's capacity and SEER (Seasonal Energy Efficiency Ratio) with your heat pump is crucial for maximizing efficiency. According to the Air Conditioning, Heating and Refrigeration Institute (AHRI), mismatched systems can result in a 30% decrease in efficiency. So, it's essential to consider both the indoor and outdoor units when replacing your HVAC system.
Parts of an Air Handler
Your air handler consists of several key components that work together to regulate the circulation and temperature of indoor air. Let's take a closer look at each of them:
Evaporator Coil
The evaporator coil is a crucial part of the refrigeration cycle. When your home needs cooling, the coil removes humidity and makes the air feel cooler. Conversely, when you need warmth, the coil transfers heat to the air, making it feel warmer throughout your home.
Blower Motor
The blower motor is responsible for moving the conditioned air through your home's ductwork. Depending on the model, it can operate at a single speed, multiple speeds, or variable speeds. Multi-speed and variable-speed motors offer more control, energy efficiency, and improved comfort.
Air Supply and Return Plenum Connections
These connections are where the ductwork is connected to the air handler. The supply plenum delivers conditioned air to your living spaces, while the return plenum brings back the air that needs to be heated or cooled.
Filter
Before the conditioned air enters the ductwork, it passes through an air filter. This filter helps minimize the circulation of particulates throughout your home and keeps your indoor components clean.
Optional Electric Heat Strips
In some situations, when additional heating is required, electric heat strips can be activated to provide auxiliary heating.
The In's and Out's of Handling Air
The air handler, in coordination with your HVAC system's ductwork, creates a recurring cycle by delivering air out through supply vents and drawing air in through return vents. It's crucial to ensure balanced air supply and movement to maintain the system's efficiency and your indoor comfort. Inadequate airflow can compromise efficiency and impact your overall comfort. This highlights the importance of professional installation by a licensed HVAC dealer who can optimize your HVAC system's performance.
Remember, when it comes to air handlers, they are more than just a delivery service for your home's comfort. They are an essential component that ensures your HVAC system functions efficiently and effectively all year round.
