You know your air conditioning system has airflow problems when it does not heat your house at all or when the heating is uneven. These problems are also signified by strange whistling noises coming out of the system. 

In some cases, airflow problems in HVAC systems lead to pressure imbalances that manifest in doors and windows slamming. Some signs indicating that your unit is experiencing airflow problems include the following.

1. Blockage of the Condenser Unit

The condenser unit can block when leaves and other debris find their way inside. As a result, the air stops flowing through the unit, causing it to overheat. When you call an HVAC repair service, they unblock the unit by cleaning it and clearing the debris. Moreover, they will assess the unit for any resulting mechanical damage and do the necessary repairs. 

2. Blockage of Vents and Registers

The furniture arrangement in your office or home can deter the free flow of air to the AC's vents and registers. Over time, your HVAC system will become inefficient. Although it is possible to resolve the problem by rearranging the furniture, repairs by experts can restore the unit's functionality if any damages have already occurred. 

3. Clogging of Filters

The filter plays the role of removing dust from the air entering the air conditioning equipment. That prevents blockage to internal components. However, a filter needs regular cleaning to remove the dust buildup. Clogging of the filter prevents the air from flowing into the system efficiently, which can cause cold and hot spots in the building. In that case, regular filter replacement is essential to ensure sufficient airflow in the system. 

4. Leaking or Blocked Ducts

When the filter is dirty, dust and debris might get into the ducts. This problem is made worse when the ductwork is too small to serve your air conditioning needs. Clogging might also occur when the ducts are too narrow. 

Furthermore, rodents and birds can build nests in the ducts, restricting airflow in the system. A duct blockage reduces the amount of air flowing into the system and compromises heating efficiency.

Expert HVAC repair services inspect air conditioning systems in residential, commercial, and industrial buildings for any problems affecting airflow in and out of the equipment. They can either repair or replace the worn or damaged parts to restore your system to its normal function and maximize efficiency. Avoid these HAVC system problems by fixing issues early enough and scheduling regular professional maintenance.
