It takes a specific amount of airflow through your HVAC system’s network of supply and return ducts to keep your home’s interior comfortable and protect against equipment damage.
If you’re experiencing an HVAC airflow problem, you may notice symptoms like:
- Hot or cold spots in certain rooms
- A pressure imbalance that causes odd drafts, whistling noises or doors slamming on their own
- Weak or inconsistent airflow from the supply registers
- Insufficient air output to maintain a comfortable temperature
Common Causes of Airflow Problems
For your HVAC system to perform well, it needs to deliver a set amount of air to each register, and return the same volume back to the equipment for reconditioning. Insufficient air movement through the system can occur for a number of reasons, including:
- Obstructions around the condenser unit that interfere with the heat transfer process, which makes cooling your home more difficult and less efficient.
- Closed or blocked vents and cold air returns that upset the system’s air balance.
- Clogged air filter, which erodes the system’s energy efficiency.
- Leaky, disconnected or damaged ducts that cause the loss of conditioned air.
- Poor ductwork design that leads to temperature inconsistencies between rooms.
- Dirty coils, which adversely affect heat transfer and erode the system’s cooling capabilities.
- A sluggish blower fan that can cause icing of the coil, and a drop in cool air output.
- Oversized equipment, which causes inefficient short cycling and ineffective temperature control.
What’s Involved in Measuring HVAC Airflow
Calculating HVAC airflow is a complicated task. It involves computing flow rates, velocity and the air volume delivered and returned through the ductwork in your home, as well as the quantity of air being pushed across the cooling coil by the fan. Then, these figures must be weighed against your equipment manufacturer’s specifications to pinpoint trouble spots.
An experienced HVAC pro has the skills and specialized equipment needed to take accurate measurements and advise you on the right solutions for any airflow problems they identify.
