What’s an HVAC Transformer?
An HVAC transformer is designed to increase or decrease the alternating current’s voltage to ensure it’s suitable for your HVAC system. The component transfers the electrical energy from a primary circuit to a secondary circuit through electromagnetic induction. Its primary role in an HVAC system is regulating the inkling voltage to ensure that it meets the system requirements. The transformer can amplify or reduce the electricity used based on the power your heating and air conditioning system needs. Hence, you want it properly functioning. Otherwise, there will be issues with your system. Part of this has a regular air conditioning service to ensure it is in top condition.
Role of a HVAC Transformer
Transformers are used for either stepping up or decreasing the incoming electrical voltage to meet the requirements of various other electrical components in the HVAC system. Its work is changing the voltage traveling to the HVAC system from the circuit board. The movement of electrical power via the transformer ensures that the AC and its various fans can work in synergy during the on-and-off cycles. If the power isn’t flowing, you might have to call an air conditioning service provider in Irving, TX because these components will either blow or not get enough power to turn them on.
The use of electrical power can be diminished or amplified based on the power needed. There are two types of transformers; step-up transformers (increase the electrical voltage) and step-down transformers (diminish the voltage). Hence, you must ensure you know which unit you need before purchasing one. Otherwise, consult your technician to have them inspect the unit. This option will save you both money and time.
Where Is the HVAC Transformer Located?
So, where is this mighty electrical component located in my HVAC system? Usually, the transformer is installed within the furnace. However, this is only sometimes the case. You could sometimes find that the component is installed outside the air conditioning system in the outdoor condenser. Hence, rather than tickle around with your heating and air conditioning system, have an air conditioning service provider in Irving, TX inspect the unit to locate the transformer’s location and replace it.
Otherwise, you might damage other electrical and mechanical components of your HVAC system. Since a transformer is an electrical component, you also might sustain injuries, electrical shocks, electrocutions, or even cause an electrical fire. Hence, you must remember that AC repair jobs aren’t DIY. They should be left to insured, experienced, and licensed professionals.
Signs That the HVAC Transformer Is Bad or Malfunctioning
So, now that you know what a transformer is, its role in your HVAC system, and where it is located, how can you determine that it has gone bad, blown, or even malfunctioned? When you turn on your HVAC system that has a bad transformer, several signs indicate that you have a bad transformer. However, some of these signs could be caused by other issues in your HVAC system. Hence, it is recommended that you immediately have an air conditioning service inspect the HVAC system to determine the root cause of the issue. Unlike you, these professionals are trained and experienced. Hence, they can use their tools to determine if the transformer has a problem and fix it on the spot. Below are the main signs that your HVAC transformer is bad or malfunctioning:
If the HVAC Circuit Breaker Is Frequently Tripping
Have you noticed the circuit breaker at home trips whenever you turn on the heating and air conditioning system? Although your HVAC transformer is the culprit, you should call a heating and air conditioning service provider in Irving, TX to conduct further inspections on the unit. An overloaded system, clogged air ducts, or an issue with other electrical components of your HVAC system might cause this issue. The circuit breakers might also trip because of another issue, like faulty wiring, which doesn’t have anything to do with your HVAC system.
As mentioned above, the transformer in an HVAC system is usually located in your furnace. The HVAC connects to a circuit breaker, a component that protects the electrical system at your Irving, TX home against any damage. If there is a sudden increase in voltage, that could damage the critical electrical components and appliances at your home. Hence, a circuit breaker is critical to protecting your electrical appliances from sudden power surges. It cuts the electrical connection whenever it senses or detects a power surge. Thus, you must have it intact by ensuring that an electrician or an air conditioning service inspects and fixes it.
An HVAC transformer regulates the unit’s power, especially the furnace. If the transformer is damaged, it will not be able to regulate the electrical flow. This might result in sudden surges in electrical power. These power surges, which might trip the circuit breaker, will increase in frequency, especially when the transformer is malfunctioning or goes bad. Additionally, the power surges might damage other electrical components in your HVAC system, like the control circuit, the capacitor, or the contactors.
Hence, whenever you notice that your circuit breaker is frequently tripping, immediately call a technician for a further inspection. If the heating and AC repair technician determines that the circuit breaker is tripping because of a damaged or bad transformer, they will take the necessary steps to replace it. Remember, replacing a transformer isn’t a DIY job. Hence, always leave such repairs to an experienced, professional air conditioning service provider.
Your HVAC System Is Excessively Vibrating or Humming
Have you noticed a humming sound from your HVAC system or other systems? The various mechanical systems at your home will usually produce noise while operating. If you hear a humming sound from your HVAC, that could be caused by the transformer. However, the production of a humming sound by a transformer is normal. A transformer has an iron core and several laminations where the coils are wired. When the iron core or the laminations contract and expand, they usually produce the humming sound you hear. In such a case, you usually wouldn’t have to call an air conditioning service provider in Irving, TX. After all, you are used to the sound.
However, suppose you notice a drastic increase in the humming sound accompanied by strong vibrations. In that case, that is a surefire sign that the transformer in your heating and air conditioning unit is malfunctioning or has gone bad. Other possible reasons for the vibrations and increased humming sound include a faulty capacitor or an incorrect installation. Hence, you should have a heating and Air conditioning service provider come over for an inspection. To ensure that the latter is addressed, you should ensure that any installation or repair is done by an experienced professional. Additionally, ensure that you follow a detailed air conditioning service plan with an AC repair company.
If the transformer in your HVAC system is damaged, it will start to hum excessively whenever you turn on the furnace. The excessive humming will then graduate to full-blown vibrating as your malfunctioning or damaged transformer deteriorates. An air conditioning service provider can properly repair or even replace the vibrating or humming transformer to ensure the furnace is functioning efficiently and operating silently again. This is also a problem that the technician will notice and fix when they come for an HVAC maintenance visit.
Your HVAC Furnace Doesn’t Produce Any Heat
All you want is a properly heated home that is comfortable during the winter. The furnace is the component of your HVAC system tasked with this responsibility. Have you noticed that the vents aren’t blowing hot air whenever you turn on the furnace?
