How To Tell If Your Air Handler Needs To Be Replaced

An air handler is a crucial component of your HVAC system, responsible for circulating air throughout your home. However, like all appliances, it may encounter issues that require attention. One common question that homeowners face is whether their air handler needs to be replaced. This blog post will delve into the signs, causes, and considerations involved in determining the need for an air handler replacement.

Signs of a Failing Air Handler

• Insufficient Airflow: Noticeably reduced airflow from vents is a telltale sign of a failing air handler.
• Unusual Noises: Grinding, rattling, or buzzing noises coming from the air handler indicate potential mechanical issues.
• High Energy Bills: An air handler that is struggling to function efficiently can lead to increased energy consumption.
• Short Cycling: Frequent on-and-off cycles of the air handler indicate a malfunction.
• Poor Indoor Air Quality: Reduced airflow can result in stagnant air, leading to poor indoor air quality and respiratory issues.

Causes of Air Handler Failure

• Age: Air handlers typically have a lifespan of 10-15 years. As they age, components may wear out or fail.
• Lack of Maintenance: Regular maintenance is essential for prolonging the life of an air handler. Neglecting maintenance can lead to premature failure.
• Oversized or Undersized Unit: An improperly sized air handler can strain the system and cause premature failure.
• Electrical Problems: Electrical issues, such as faulty wiring or capacitors, can lead to air handler malfunctions.
• Refrigerant Leaks: A refrigerant leak can cause the air handler to lose cooling capacity and eventually fail.

Considerations for Replacement

• Age and Condition: If the air handler is over 10 years old and experiencing multiple issues, it may be time for a replacement.
• Repair Costs: If the cost of repairs exceeds 50% of the replacement cost, replacement may be the more cost-effective option.
• Efficiency: A new air handler can significantly improve energy efficiency, resulting in lower energy bills.
• Warranty: Some air handlers come with warranties that cover replacement costs for a certain period.
• Professional Assessment: It is always advisable to consult with an HVAC technician for a professional assessment and recommendations.

Benefits of Replacing an Air Handler

• Improved Airflow and Comfort: A new air handler provides better airflow, ensuring a more comfortable living environment.
• Reduced Energy Consumption: An efficient air handler can lower your energy bills by up to 20%.
• Enhanced Indoor Air Quality: A properly functioning air handler helps circulate fresh air and reduce allergens and pollutants.
• Increased Home Value: A new air handler can add value to your home by improving its energy efficiency and indoor air quality.

Steps Involved in Air Handler Replacement

• Turn Off Power: Before starting any work, turn off the power to the air handler at the main electrical panel.
• Disconnect Electrical Wires: Carefully disconnect the electrical wires from the air handler.
• Remove Refrigerant Lines: If applicable, remove the refrigerant lines from the air handler.
• Unbolt and Remove: Unbolt the air handler from its mounting and carefully remove it.
• Install New Air Handler: Install the new air handler in the same location as the old one.
• Reconnect Electrical Wires: Reconnect the electrical wires to the new air handler.
• Connect Refrigerant Lines: If applicable, connect the refrigerant lines to the new air handler.
• Test and Commission: Turn on the power and test the new air handler to ensure proper operation.
