Condenser Fan: Airflow is essential for the coil and compressor to work, so the coil must be kept clean.
There are two different types of AC system fans, however. Assuming you have a central AC system, it will likely feature a condenser fan and a blower fan, both of which are essential to its cooling performance.
What is the purpose of fan mode in AC? The fan mode in your AC is designed to circulate air throughout the room. Instead of cooling the air, it simply moves the existing air around.
The average cost of a new condenser fan motor ranges between $300 and $700, depending on the model, your AC unit, and labor costs. While this isn't cheap, replacing your fan motors before they break can save you thousands of dollars in HVAC repair services.
If your AC is on but not blowing air, check the thermostat settings first. A clogged air filter may also block airflow and needs replacing. The blower motor could be malfunctioning, or ductwork might be disconnected or blocked, affecting air circulation throughout your home.
In short, common issues that can cause an air conditioning unit fan to stop spinning are electrical issues, problems with the capacitor, contactor issues, a burnt out air conditioner motor, a broken fan belt, or clogged air filter.
For AC capacitor replacement, anticipate spending between $150 and $400, depending on the capacitor's type and accessibility. A bad AC capacitor is a fairly minor repair, and most HVAC technicians will recommend a repair rather than replacing the unit when the capacitor is the problem.
Blower motors are designed to last just as long as your furnace itself, anywhere from 10 to 20 years. Just as with any HVAC system, the better maintained and serviced your equipment is by experienced HVAC technicians the longer it will last and the fewer repairs you'll face.
Cost for a single-stage blower motor could run between $300 and $900, while cost for a variable-speed blower could be between $600 and $1,500. Remember, though, the higher upfront costs for a variable-speed blower motor will be offset by reduced monthly energy bills.
An AC fan failing to spin can indicate one of several problems with the components that drive the fan blades. It is important to have a professional check if the fan motor, capacitor, belts, and bearings are all functioning properly. If any element is causing a problem, it may be impacting the AC fan's ability to work.
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
Your HVAC fan should turn on and off with the rest of your heating and cooling system. It's normal for the fan to kick on a couple of minutes before heating starts or to stay on for a couple of minutes after cooling stops, but your fan shouldn't run for hours on its own.
What does the fan setting on an air conditioner do? It activates the unit's fan to circulate the existing air in the room without engaging the cooling mechanism. This way, it helps in creating a fresh ambiance without significantly altering the room's temperature or humidity levels.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Your AC's blower motor is responsible for moving air through your air conditioner to cool it and then pushing it back out into your home. Without this incredible component, your AC can't provide any cooling effect, no matter how much the compressor runs.
The average blower motor replacement cost is $560, but the final price depends on labor fees, as well as the cost of the parts. Some higher-end models feature large or hard-to-reach motors, which could bring your HVAC blower replacement cost to as much as $2,400.
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
The Cost of Not Replacing It
Because of how hot the system runs, running your AC with a failed fan motor could result in your compressor failing, too. The compressor is a much more expensive component, typically running $1,400-$3,000, so procrastinating on AC repair could be a very costly delay.
Your AC is rendered useless without a functioning fan or furnace blower motor. This could also mean that you need a furnace repair or should start looking at costs for blower motor replacement. In addition, you will either suffer from no air or weak airflow with fan problems.
Resetting your AC unit usually involves turning off the power, waiting for a specific duration, and then turning it back on. This process can vary slightly depending on the make and model of your unit. Typically, you'll find a reset button on the outdoor unit. Press and hold it for a few seconds.
While your AC will still work with a bad capacitor, it will struggle to function correctly. Eventually, the system will stop working altogether. Extended use can cause further damage internally. We recommend contacting a professional to handle the repairs so that you don't risk any damage to your air conditioning.
Can You Replace an AC Capacitor Yourself? Replacing a capacitor is a relatively simple task that most people can do themselves with a little bit of research. However, it is important to remember that capacitors store a lot of energy, so it is necessary to discharge the capacitor before working on it.
On average, AC compressor costs range from $800 to $2,300, with most folks paying $1,200 for a new one. However, your price will vary depending on factors like the size and brand of your compressor. Before you schedule your replacement, read on to learn about all AC compressor cost factors.
