5 Causes of Inefficient Airflow in Heating and Air-Conditioning Units

Air Conditioning Issues

Heating and air-conditioning units are essential not only for keeping temperatures consistent but also for safety, reducing energy bills, comfort, and increasing productivity levels. Adequate airflow is essential for the efficient operation of air conditioners. Heating and air-conditioning units require an efficient flow of air to ensure heat exchange to keep your home cool. As a result, all rooms in your home receive conditioned and heated air.

You will at some point experience airflow issues with your heating and air-conditioning unit. As such, you need to know what to look for and act fast enough so that you avoid severe issues and prevent other components from developing faults. You need to learn about the common causes of inefficient airflow for the systems so that you can act quickly by hiring a heating and air-conditioning unit repair expert in Knoxville, Tennessee to fix the issue.

Leaking air ducts

The supply and return air ducts can result in airflow issues for a heating and air-conditioning unit. Wear and tear and loosening connections and joints cause damage to the air ducts, which make them leak. Leaking supply air ducts causes heated or conditioned air to escape the ducts, which leaves some rooms unserviced. Return air ducts suck in moisture-laden and dirty air, as well as overworking the unit.

Blocked vents and registers

Blocked vents are a common cause of inefficient airflow in office settings because workmates don’t usually agree on a reasonable temperature, and furniture such as cabinets are usually pushed in front of the vents. The obstructions compromise on airflow, which affects the efficiency of the entire heating and air-conditioning unit. Additionally, it is hazardous if a flammable object is placed in front of the vent.

Common Problems of Air Conditioners

Obstructed condenser unit

Air-cooled units have a condensing unit that is usually located in a mechanical room or outside the room. Outdoor systems get obstructed by debris and leaves that accumulate around the system. Units in the mechanical room can also get obstructed by storage items or other equipment. The system overheats when it lacks access to air, which affects the flow of air in the heating and air system. Make sure that you clear the space around the system to prevent issues with the airflow.

Dirty coils

Heating and air-conditioning units have two types of coils known as the condenser and evaporator coil. The former picks up heat inside the room and vaporizes it, while the latter removes the heat and exchanges heat with the air outside the house. Debris or dirt that accumulates over the coils tampers with the efficient flow of air, leading to inefficient heating and cooling.

Dirty filters

A heating or air-conditioning unit experiences inefficient airflow when the filters are dirty. The filters are responsible for cleaning air in the room. As such, airflow is tempered with when the filters are dirty and the holes get blocked.

You need to hire an expert in HVAC once you notice the airflow issues mentioned above. The technician will inspect the unit, diagnose, and offer an appropriate remedy. Now that you know the problems, you can take the necessary proactive measures.
