Solving Common Airflow Issues in HVAC Systems

Do you have airflow issues? Maybe you’ve complained about a room being too hot while the rest of the house is cold. Or have a utility bill that continues to rise. 

There are many things that can cause airflow issues in your HVAC system. The best place to start is with a well-maintained system. 

But sometimes, even the best-maintained HVAC system can cause problems. What do you do then? 

How HVAC systems impact a home’s airflow

Your HVAC system is responsible for the circulation of air throughout your home. The system draws air from the outside, filters it, and circulates the conditioned air back into each room. If there is an issue with your HVAC system, it can affect your home’s entire airflow.

What are the most common airflow issues?

Blocked vents and registers

This occurs when a piece of furniture or large object blocks the vent, preventing the airflow from circulating. It’s easy to solve; walk around your home occasionally and remove anything blocking circulation. 

Clogged air filter

A dirty or clogged air filter can restrict the airflow from your HVAC system. Make sure to check and change your air filter every three months to ensure your system’s maximum efficiency, or more often if you have an active home. 

Obstructed condensing unit

The condensing unit located outside your home may be obstructed, restricting the airflow. This causes your HVAC system to work harder than it should. Remove any debris that may block the condensing unit, especially in the spring, as you’re getting ready to turn the air conditioner on for the first time.

Blocked or leaking ducts

Since ductwork is often hidden behind the walls, it can be challenging to spot an issue. Seasonal inspections can alert you to any problems and fix issues before they escalate.

Thermostat troubles

A malfunctioning thermostat can trigger airflow issues. If you experience inconsistent temperatures in different rooms, your thermostat may be the cause. Check if your thermostat has dead batteries, a loose connection, or miscalibration.

Dirty condenser coils

Dirty condenser coils obstruct the airflow from the HVAC system, resulting in poor performance, high energy bills, and uncomfortable temperatures. Clean the condenser coils regularly to avoid this issue.

Low refrigerant

If your system is low in refrigerant, you may notice that the air from your vents is not cold enough. Call a professional HVAC technician to inspect and refill the refrigerant.

Improperly sized furnace or air conditioner

An improperly sized furnace or air conditioner can lead to inadequate airflow in your home, which means your system is not generating enough hot or cool air. If you suspect this may be your problem, a reputable HVAC company can help.

Old equipment

Old and outdated HVAC systems may experience airflow issues as they age. Consider upgrading to a more modern system to improve airflow and efficiency in your home.

Is it time for a new HVAC system?

HVAC system airflow issues can cause discomfort, high energy bills, and unhealthy indoor air quality. The good news is most common airflow issues are easy to solve.  

Simple inspections and regular maintenance are key to ensuring your system can function at its highest capacity, keeping your home comfortable and healthy. How can we help you?
