If your HVAC is blowing air but not regulating your indoor temperature, there could be several reasons behind it. Issues with airflow, ductwork, blower motor, refrigerant levels, and dirty filters are among the most common culprits. Fortunately, many of these problems can be resolved quickly and easily without calling in a professional. Here are some of the most common reasons why your HVAC may be malfunctioning, how you can fix them on your own, and when it's time to call in the pros.

Dirty Filters

When was the last time you changed your air filters? Dirty filters are one of the main reasons why your HVAC is blowing air but not heating or cooling the space. Over time, dust, pet hair, and other debris accumulate on the filters, causing them to become clogged and restricting airflow. This, in turn, can cause your system to work harder, leading to poor performance, high energy bills, and, ultimately, HVAC failure. To prevent this, make sure you replace your filters every couple of months.

Ductwork Issues

Faulty ductwork can also cause airflow problems, leading to poor temperature regulation and your HVAC not working properly. Issues like leaks, gaps, or disconnected ducts can cause hot or cold air to escape, making your system work harder and not delivering the desired results. You should inspect your ductwork for signs of damage regularly and seal any leaks or gaps with duct tape or mastic sealant.

Blower Motor Dysfunction

If the blower motor in your HVAC is not working properly, you may notice low or no airflow, strange noises, or poor temperature control. The blower motor is responsible for blowing air into your home, so if it's not functioning, the air can't circulate properly. Some signs that your blower motor may be failing include reduced airflow from vents, unusual noises, and an increase in energy bills. A faulty blower motor should be repaired or replaced by a professional.

Refrigerant Levels

HVAC systems rely on refrigerant to either absorb or release heat, allowing for temperature regulation. If your HVAC isn't cooling your home and is just blowing air, it's possible that the refrigerant levels are low. A refrigerant leak can be hazardous to your health and require professional help.

When It's Time to Call in the Pros

While some HVAC problems can be quickly and easily resolved, others require the help of an expert. If you've tried all of the above methods and your HVAC is still not functioning correctly, it's time to call in professionals. Not only can they fix the underlying issue, but they can also help prevent future HVAC problems.
