What You Need to Know About Air Conditioning Repair

When your home’s air conditioning repair system needs repair, it can be a scary prospect. You have to decide whether you want to pay for a repair or replace the system completely.

A professional technician will be able to diagnose your issue and give you all your options. They can help you decide which is the best course of action for your home and your budget.


The thermostat is an important part of the entire HVAC system. It regulates the temperature of your home and activates the heating or cooling system if it is too hot or too cold.

A thermometer attached to the thermostat sends a resistance signal that is read by a microcontroller and translated into an actual temperature with precision to the exact degree. A set of coils and pulses closes the contacts when the resistance is too low or opens them when the temperature is too high, allowing the heating or air conditioning system to activate.

If the thermostat is registering incorrect temperatures, this may indicate that the sensor is malfunctioning or there is a broken connection between the unit and your HVAC system. In such cases, the best solution is to replace the unit with a new one.

Thermostats are small but critical components of your home’s HVAC system and can be a source of many problems. However, some simple maintenance steps can resolve many issues, and keep your home running efficiently for a long time.

Condenser Fan

The condenser fan is a critical part of your air conditioning system. It keeps the condenser cool and prevents it from overheating, which can result in expensive repairs down the road.

In general, the condenser fan should rotate clockwise (CW) when it is turned on and counter-clockwise (CCW) when it is off. If you notice that the motor doesn’t spin, it is probably time for a replacement.

It is also a good idea to inspect the shaft of the motor for any signs of wear, such as grinding or a clog. This can indicate a worn bearing that is binding the blades of the fan.

Other common causes for the condenser fan to stop spinning include a burnt-out motor or a bad start/run capacitor. Capacitors can fail for a number of reasons, including age, running too long, power surges, and overheating.


The compressor is one of the most important parts of an air conditioning unit. It’s responsible for releasing refrigerant from the outdoor part of the unit and circulating it through the indoor coil.

There are many different kinds of compressors, including rotary screw and piston models. They are a common choice for industrial applications and are available with both oil-lubricated and oil-free designs.

Compressors can be powered by electricity, fuel, or steam. They’re typically a two-part system, consisting of an engine block that pumps gas or air from a smaller chamber to a larger one, and a pressure regulator that maintains stable air pressure.

They are used for a variety of purposes, from inflating tires to powering jackhammers on construction sites. They’re also often found in refrigerators and HVAC systems at arenas.


Evaporator coils house a chemical refrigerant that cycles between liquid and gas phases, absorbing heat from the air and producing cold air. Without the evaporator, your AC would not be able to complete its cooling cycle.

If you notice a leak in your evaporator coil, it is crucial that you get it repaired as soon as possible. This is because a leaking coil could cause your system to work much harder than it needs to, which can eventually lead to system failure and a big bill for repair or replacement.

The evaporator coils of your AC unit need to be cleaned and maintained on a regular basis. This is to prevent them from becoming dirty and moldy.

The evaporator coils also need to be replaced when they are damaged or worn out. This can be done by a professional AC technician. In addition, it is important to change your AC’s air filter regularly, especially during the months when you use your AC most often.
