Signs It’s Time To Replace The HVAC Blower Motor With Air Conditioning Repair | San Antonio, TX

An HVAC system failing should be the last thing you want to experience when the summer temperatures increase to uncomfortably high levels. Being an electrical appliance, this is, however, bound to happen. The blower motor is one of the many elements in your HVAC system that might malfunction or fail. Hence, you want it in excellent condition.

However, like any other mechanical part, the blower motor will eventually wear out and must be replaced. Suppose you notice that the blower motor is faulty and unable to blow the conditioned air into other parts of your home. You should call an air conditioning repair technician immediately. Only by having the blower motor replaced can your home be effectively cooled or heated again.

Many factors can make your HVAC system ineffective. Sometimes, the problem is minor, and an air conditioning repair technician can quickly address the underlying issue. This isn’t always the case. Other problems require replacement because repairs are cost prohibitive, uneconomical, or impossible. A blower motor that isn’t working properly can significantly impact your home’s comfort levels. It can also have a serious effect on indoor air quality. Here are signs that your blower motor needs to be replaced:


Have you noticed a burning smell when you pass near your blower motor? That is a sign it is overheating. The air handler might overheat because of various reasons. For instance, grime and dirt may accumulate around the motor, preventing it from venting. This may result in a buildup of heat in your blower motor over time. However, this is a problem that you can resolve with a routine air conditioning service from your reliable technician.

Age is, at times, the largest threat to your HVAC system. If the blower motor is worn out or too old, it cannot be easy to cool your home. Issues like this additional strain might make the blower overheat, resulting in breakdowns or even higher energy costs. In such a case, having an air conditioning repair technician replace the blower motor is the only viable solution.

No Airflow from the HVAC Unit at All

There are several reasons your HVAC unit might not be blowing any air. The most common reason is that the blower motor has failed and needs to be replaced. Other possible causes include a clogged air filter, a tripped circuit breaker, or a blown fuse. If your HVAC unit isn’t blowing any air, the first thing you should check is the blower motor. If the motor has burned out, it will need to be replaced. A qualified air conditioning repair technician should install a new furnace blower motor.

The other issue that could impact the blower motor functionality is a blocked or dirty air filter. A clogged air filter can restrict airflow and cause the blower motor strain to push air into your San Antonio, TX, home, making it overheat and fail. If the circuit breaker has tripped, it will need to be reset, and if the fuse has blown, it will need to be replaced. Once these issues have been resolved, your HVAC unit should start blowing air again. When you notice there isn’t enough airflow into your home, have an air conditioning repair technician come over for an inspection and repair rather than do the repairs yourself.

Strange Sounds from the HVAC Unit

If you start hearing strange sounds from your HVAC unit, it could signify that the blower motor needs to be replaced. The blower motor is responsible for circulating air throughout the unit, so if it starts making noise, it will not be able to do its job as effectively. Some of these sounds denote a problem that can be easily addressed by an AC repair professional.

However, others mean that a component, such as a belt, must be replaced. For instance, a screeching or squealing sound means that your HVAC system’s blower motor has bearing problems or a broken belt. The air conditioning repair technician will have to replace the belt and bearings to address this. The professional will also have to lubricate the bearings.

If the motor generates banging, clanking, or rattling noises, there might be a loose or damaged component to blame. Loud thumping noises are very unsettling. They mostly indicate that something is broken or unconnected. And doing so might include changing the blower motor. No matter what kind of odd noises your HVAC blower motor produces, you should immediately switch the system off and call an air conditioning repair company. While issues like a damaged or loose belt and poor alignment are simple to repair, if you delay fixing them, they may cause harm to the motor or other nearby components.

Unexplainably High Energy Bills

The blower is the component of your HVAC system that pumps all the air into your living space. Your HVAC system’s component also uses most of the energy. Hence, it may well be the culprit whenever you notice a considerable rise in electric utility bills. A problematic, aging, dirty motor will work harder to sufficiently and properly circulate the conditioned air throughout your home. Therefore, you’ll notice an increase in the electricity utility bills.

Suppose your HVAC system is past its rated lifespan or uses a single-speed air handler. In that case, you should consider having an air conditioning repair technician replace the blower motor with a variable-speed model. These blower motors can adjust their energy use automatically to meet your San Antonio, TX, home’s constantly varying cooling and heating needs. Therefore, it reduces wasted energy.

If you notice any of these signs, turn off your HVAC system and call a qualified air conditioning repair technician to inspect the unit and possibly replace the blower motor. If you need air conditioning service in San Antonio, TX, contact us at bluefrog Plumbing + Drain + HVAC of San Antonio.
