An air handler is the part of a heating, ventilating, and cooling (HVAC) system that circulates the air around your home and returns it to the system.
When your air handler is malfunctioning, it can have a deteriorating effect on the rest of the system. To make up for the malfunction, the rest of the system will work harder, which causes the unit to break down more often, forcing you to spend more money on repairs and energy costs.
What are common problems that cause them to break down?
- Damaged coils: Coils need to be cleaned, due to blockage caused by dust and debris. When they are clean air can flow properly, so the system can cool as it should.
- Clogged air filters: As with the coils, filters can also become clogged with dust and dirt. If the filters are cleaned or replaced every two to three months, depending on the location, they will help keep the coils clean.
- Faulty wiring: Faulty wiring can cause the unit to work much harder than it should to maintain the proper temperature.
- Malfunctioning blower: Bad wiring will cause the system’s blower to break down, therefore hot or cool air will not be moved through the duct system, prohibiting it from reaching other rooms in the home.
What are some benefits of replacement?
It is likely time to replace your air handler if the cost of repairing it is higher than 50% of the cost of having a new one installed. Some other benefits and reasons to replace are below:
- You should consider replacement if your system is more than 12 years old and it is causing problems
- New systems use less energy, are highly efficient and environmentally friendly, and can lower your utility bills significantly
- Tax credits are also offered in certain areas for installing a high-efficiency system
- Newer systems also provide more efficient humidity control, maintain even temperatures, and give a constant flow of cool air
- In addition, new filtration systems increase indoor air quality
