Signs You Need to Repair the Air Handler

Common problems that can affect your air handler include:

  • Damaged blower — If the air filter isn’t replaced on a regular basis, debris can build up in the air handler and cause damage to the blower.
  • Frozen evaporator coil — This is a common issue in air handlers. If the evaporator coil is frozen, you likely have blocked air filters or low refrigerant levels. Frozen coils can cause you to experience a lack of cooling.
  • Loose fan belt — If you hear loud squealing noises coming from your air handling unit, or notice the smell of burning rubber, the fan belt is likely loose. We can easily fix this problem by replacing the fan belt.
  • Leaking refrigerant — Do you hear hissing sounds coming from the air handler? It might be leaking refrigerant. In addition to driving up your utility bill, leaking refrigerant can also turn into a health hazard. Our Manchester AC repair experts will fix the leak and recharge your system with the appropriate level of refrigerant.

What’s Inside the Air Handler?

The air handling unit is an essential part of  your cooling system and features the following components:

  • Blower — The blower is responsible for pulling in warm air and leading it towards the evaporator coil. The blower also works to ensure that cool air is efficiently circulated through your AC system.
  • Evaporator coil — This is where the warm air is cooled before it is directed through the supply vents and into your home. The evaporator coil can become frozen due to a clogged air filter, low refrigerant, or restricted airflow.
  • Air filter — The air filter is responsible for keeping dust, dirt, and other debris from accumulating inside the air handling unit. Regular filter replacement is a crucial part of AC maintenance, and should be carried out every two or three months.

Looking to Just Replace the Air Handler?

We often get questions from homeowners about simply replacing their air handler, while keeping the current outdoor unit. While this may seem more cost-effective than changing both indoor and outdoor units, it’s actually not a practical long-term solution.

According to industry standards, both the indoor air handler and the outdoor compressor are required to have matching coils, refrigerant, and SEER ratings. If you opt to replace just the air handler, the new unit will likely have a higher SEER rating than the existing outdoor unit. This imbalance will result in recurring cooling problems and premature system failure.

If you are prepared to move forward with AC or heat pump replacement, give us a call to request an estimate.


Are you experiencing unexpected problems with your heat pump or air conditioner? There is likely an issue with the air handler. Worn out components in the air handler can cause cooling inefficiencies.
