Heating and Air Conditioning Air Flow Problems

Heating & air conditioning system air flow problems are common issues that most homeowners will face during their lifetime. No matter if you are dealing with hot and cold spots in your house, weak airflow, or have pressure imbalances, air flow problems can be a sign that you need to have maintenance performed on your HVAC unit. There are several reasons why you may be having HVAC airflow issues and we’ve come up with a list of the Top 10 Causes of Airflow Problems in Heating and Air Conditioning Systems.

Top 10 Causes of Airflow Problems in Heating and Air Conditioning Systems

1. Obstructed Evaporator – Your indoor evaporator unit can become blocked by dust and dirt from using cheap filters or not changing them often enough.

2. Blocked Vents and Registers – Air conditioning vents should be kept open and vents and registers should not be blocked.

3. AC Unit is too Big – Units that are too big for your home will not run efficiently. AC units need to run long enough to remove humidity from the air.

4. Malfunctioning Thermostat – Thermostats can malfunction if they are old or if their batteries need to be replaced.

7. Faulty Ductwork – Heating and air conditioning professionals can determine where the issue lies within the ductwork and how to best fix it.

8. Malfunctioning/Dirty Blower Fan – The blower fan may be dirty or malfunctioning and can be serviced by an HVAC technician.
