If your home has an AC repair unit, you know how important it is to keep it up and running efficiently. But when it starts to make strange noises, or your unit becomes damaged, you may wonder how to go about getting it fixed. There are a few things to keep in mind before contacting a professional to come out and do the work for you.
Blowers
The blower in your air conditioning system plays a major role in the operation of the system. If your blower is malfunctioning, it will be hard to cool the room. This can cause you to pay more for your energy bill.
It is important to have a trained HVAC technician inspect your blower. They can find out whether it’s defective and give you the best possible repair.
Some of the most common problems with the blower include clogging filters and ducts. These can lead to overheating and inefficient air flow.
A dirty motor can also lead to an electrical short. That can lead to a blower motor failure, requiring an expensive replacement.
Motors
If you notice that your AC is making a strange noise, or there isn’t enough cold air, your system may have a problem with its motors. You should call an HVAC technician to fix the problem.
There are two main types of AC motors used in HVAC systems. Synchronous and Induction. The synchronous motor has a DC supply and a stator winding with a three phase AC supply.
The rotor of the synchronous motor is a cylindrical squirrel cage rotor pressed onto a steel shaft. It is surrounded by a frame and two end brackets.
These rotors are made by stacking thin steel laminations. They are the most commonly used type of motor.
Belts
If your car’s air conditioning system is making strange noises, you may have a faulty compressor belt. This is especially true if the AC isn’t working in winter defrost mode. Luckily, the problem can usually be fixed.
The first thing you need to know is that there are many different types of belts. For example, there are serpentine belts, V-belts, and cogged belts. These belts help your car maintain an even temperature.
Serpentine belts are typically made of rubber. They can be a good choice for older car models, but they can also wear out after years of use.
As a general rule of thumb, if the A/C isn’t working properly, it’s probably time for a replacement. The average A/C compressor belt lasts tens of thousands of miles.
Electrical components
Fortunately, many of the common problems associated with your AC can be easily fixed. But before you get started, there are a few things you should know about electrical components.
One of the most important is the capacitor. The capacitor is a small device that stores electricity. It’s used to provide the necessary voltage to run a fan and compressor. Failing capacitors can cause expensive repairs to your air conditioning system.
Another component is the contactor. This device is like a switch in your outdoor condenser unit. It turns the AC on and off. A failing contactor may make a loud buzzing noise and may cause leaks.
