A well-maintained air conditioning system does more than keep your home cool. It also helps you save money by reducing energy consumption.
Capacitors are one of the most common AC repairs. They wear out over time and can prevent your system from starting when it’s called upon to do so.
- Faulty Thermostat
Your thermostat is the brain of your HVAC system, and many problems can be traced back to it. It controls the temperature of your home, making sure your heating and cooling equipment turns on when needed. If it doesn’t work properly, you can suffer from discomfort, high energy bills, and expensive AC repair services. Recognizing the signs of a faulty thermostat is essential to preventing these issues and getting it repaired or replaced in a timely manner.
Among the most common symptoms of a thermostat problem is a discrepancy between your home’s temperature and what the unit is reading. This can be caused by a broken sensor, power supply issue, or even a malfunctioning control board. If this happens, you should replace the batteries in the thermostat and try again. If it doesn’t fix the problem, you should contact a professional to do a diagnostic check.
Another sign that your thermostat may be broken is if you have trouble turning the air conditioner on or off. This can be a sign that the system is working too hard or that it isn’t able to reach the desired temperature. This is a good time to consider replacing your thermostat with an updated model that will be more energy efficient.
Lastly, you should always make sure that your thermostat is set to the correct mode (heat in winter and cool in summer). It also helps to clean the vents frequently and change the filter to prevent mold from growing inside them.
- Faulty Fan
If your AC fan is not spinning it could be an indication of a motor failure. If your fan isn’t working properly it will not be able to cool your home effectively.
A faulty fan can be caused by many different things. A common issue is that the motor bearings have worn out. This can occur if the fan has been working very hard and hasn’t received regular maintenance. Alternatively, it can be an electrical issue, such as a blown fuse or relay, or it can also be due to loose wiring connections and shorts.
Another reason that your fan might not be working is because the breaker switch has tripped. If this is the case, it is a simple fix by simply resetting the breaker. However, if there is a more serious problem that is causing the breaker to trip it’s best to contact an HVAC technician for AC repair services.
Inside your air conditioning unit is a capacitor that stores energy and provides power to the fans. It’s not uncommon for capacitors to go bad for numerous reasons and restrict one of your AC system’s fans from spinning. This is something that needs a professional Tampa AC repair technician to address.
The squeaking or humming noises that a failing fan may make are another indication that it’s time to get professional AC repairs. This is most likely a sign that the motor bearings have worn out and will need to be replaced. This can be a costly repair that’s why it is so important to keep up with regular maintenance on your AC system. This will help prevent the need for any major repair or replacement work down the road.
- Faulty Compressor
The compressor is one of the most vital parts of your AC system. It compresses refrigerant gas and sends it through your air conditioning system to remove heat and excess humidity from your home. The compressor is very reliable, but it does have a lifespan that will eventually expire. The lifespan of your compressor can be extended, though, through regular preventative maintenance and by addressing any issues as soon as they arise.
When a compressor is faulty, the first thing you will notice is a lack of cold air from your vents. This can indicate a variety of things, including a dirty air filter, clogged condensate line, or low refrigerant. If you call our technicians right away, they can help you resolve these issues before they damage the compressor.
Strange noises from your compressor also point to a possible malfunction. Chattering, whining, rattling, and other sounds can be caused by a faulty compressor clutch or seized shaft. They could also be a sign that the compressor oil used for lubrication has become contaminated with water vapor or is insufficient.
Other problems that can indicate a faulty compressor include leaking refrigerant, visible physical damage to the compressor unit, or a high-speed motor failure. If the compressor starts to overheat, it may cause a fire. Similarly, if the compressor overheats frequently, it may cause electrical issues that need to be addressed by an electrician.
Finally, if your circuit breakers keep tripping when you use the AC, this is another indication that something is wrong with the compressor. This can be an indicator of a faulty compressor or a refrigerant leak, both of which should be taken care of by our experienced technicians.
- Faulty Contactor
The contactor is an air conditioning mechanism that helps the system to turn on when your thermostat signals a need for cooling. It connects high-voltage power to the compressor and fan motor to get the job done. Unfortunately, the contactor can develop faults that stop it from working properly. This can lead to various problems such as loud humming noises and overheating of the unit.
You can try to troubleshoot the problem of a faulty AC contactor by performing some electrical tests and by physically inspecting it for signs of wear and tear. It is also essential to note that you should always turn off the power to the air conditioner before attempting any maintenance or inspection. This will help to prevent potential accidents due to electrical shock.
In terms of electrical testing, a good way to check the condition of your contactor is by using a multimeter. First, make sure that the power is turned off at both the thermostat and breaker level. Then, remove the side cover of the condenser unit and locate the wires that are connected to the contactor. You will see several colored wires connected to a black rectangle that is positioned vertically. Take a picture of the wires and the contactor for reference.
Once you have removed the side cover, you can begin to test the voltage of the contacts. Ideally, the contactor should have a reading of between 5 and 20 volts when it is functioning correctly. However, if the test results in a lower or no reading at all, then the contactor may need to be replaced. Once you have purchased a new contactor, you can follow the same steps to replace it and rewire the wires.
- Faulty Blower Motor
The blower motor is at the center of your air handler, pumping cool and warm air throughout your home. When this important component malfunctions, your airflow is compromised. There are a few signs that you might need to have it repaired or replaced.
The first sign of a bad blower motor is reduced airflow from your vents. This could be due to a clogged air filter, but it may also mean that the blower motor is having trouble operating. If this is the case, it’s best to turn off your furnace and allow it to cool down before attempting any repairs.
Another sign that your blower motor is having trouble is if it’s making rattling or clanging sounds. This can indicate that the motor is overheating or that it’s nearing the end of its lifespan. A professional will be able to help you determine whether it’s better to repair or replace the blower motor, and they can make sure that you select the correct model for your air conditioning system.
A faulty blower motor can also cause your energy bills to climb. This is because it takes more electricity to power the motor when it’s having problems.
Other signs that your blower motor is having trouble include being unable to change the fan speed. This can happen if the blower motor resistor fails. This part controls the power to the blower motor, so if it stops working, you won’t be able to change the fan speed. If you’re unable to change the speed of your blower motor, it’s worth contacting an HVAC company to check whether the resistor is faulty. If it is, a replacement should be relatively inexpensive.
