The air conditioner blower fan is a critical component of your air conditioning system. It aids in the distribution of cool air throughout your home. Sadly, these motors are easily damaged. Furthermore, many factors can cause your AC blower to break down and require AC repair. So, how do you keep your AC blower fan running smoothly? Before we delve into blower fan maintenance, we must first understand what they are and how they work.
What Is an AC Blower Fan?
The AC blower fan, also known as a blower motor, is the component that drives your air conditioner fan. Cool air can blow into your home through the ductwork because of the blower motor, while hot air is blown out. Your air conditioner will not function unless it is properly turned on. So, if you want to improve energy efficiency and ensure your home is always at its most comfortable temperature, the blower in your AC system must be operational.
Types of AC Blower Fans
Condenser Fan Motors
Condenser fan motors are for use outside. You can see them on roofs, ventilators, air conditioning ducts, or ductwork. They increase airflow in heating and cooling systems in both residential and commercial applications. The sealed ends of condenser fan motors keep water and other elements out. Fan motors come in a single or dual capacitor.
Blower motors are the same as condenser motors but have vents at their sides to let air pass through easily. However, if dirty air gets trapped around them, it will damage them and cause the whole system to overheat.
These are blower motors with an electric control module mounted at the ends.
Combustion Fan Motors
These are fan motors found in gas furnaces. They have two wires instead of a capacitor.
Compressor motors typically have an external condenser and an internal suction or discharge line connecting to the evaporator coil inside the home.
Symptoms of a Faulty AC Fan Motor
The most telltale symptoms of a failing AC fan motor are rattling, grinding, and clunking. In addition, if your air conditioner does not start or stop at the appropriate times, you may have a problem with your fan motor.
HVAC Maintenance Tips to Keep Your AC Blower Fan Running Smoothly
Replace your thermostat
If you have a thermostat that is more than a few years old, you should consider replacing it with a newer model. Modern thermostats frequently include unique features that can help you save money on heating and cooling costs. In addition, many of the top options are programmable, allowing you to tailor them to your specific requirements.
Remove any dirt from around your AC unit
The outdoor unit must be clear of leaves, branches, dirt, and overgrown grass to prevent your motor from overheating. If any of these items obstruct the airflow, simply remove them and clean the unit as needed.
Inspect vents on a regular basis
Keeping your HVAC registers and vents clean is critical to maximize airflow and prevent overheating. Excessive dirt can clog your air filter, so inspect and replace it as frequently as possible.
Change the air filters
It is critical to keep your air filters clean. If dirt or debris obstruct them, it can block airflow and lead to more significant problems later. The most effective way to avoid problems is to replace them regularly.
Clean the condenser coils
If your AC unit is outside, you must clean the coils at some point. Dirt can accumulate on the coils, and this will, in turn, prevent the fan from functioning properly. To clean the coils, remove them first and then scrub them clean.
