10 Common Air Conditioning Problems & How to Fix Them

Since AC repair in Mount Washington can be pricey, it’s critical to keep your air conditioner in good working order by performing routine maintenance.


A blocked or dirty filter is one of the most common causes of air conditioner failure. Follow the manufacturer’s instructions for replacing your air filter. Some are used once a month, some three times a year, and some are reusable and should be cleaned as needed.

Checking if any light passes through a filter to see if it needs to be cleaned is one technique to tell. It’s time to clean it if it isn’t already.


One simple solution is to ensure that your thermostat (which regulates the temperature in your home) is turned on, that the inside is clean, that it is level, not exposed to sunlight, and that it is set to the correct temperature. If the issue persists, it could be a sign of something more serious.

Refrigerant leaks

When the air conditioner’s coolant leaks, the device will stop working properly, causing temperature fluctuations. Because the position of the leak influences the cost of repair, it’s a good idea to have it checked out once a year by a qualified air conditioner servicing near me.


The drain tube, like the filter, can become blocked with debris, dust, and lint. The drain pan will fill up if it becomes clogged, and water will flow out, potentially causing harm to the AC unit or whatever is near your pan.

Breakers or Fuses

One of the first things an HVAC professional looks for when a motor fails is the breaker. Breakers and fuses protect the engine or compressor of the air conditioner from overheating. 


The motors that drive the compressor and fans won’t work without capacitors. The start capacitor transmits a single jolt to start the motor, while the run capacitor sends a succession of jolts to keep it running. If any one of these components burns out, the AC unit will not function properly.


The compressor applies energy to the refrigerant to carry out heat exchange and propels it through the coils. The air conditioner will not cool your home if the compressor fails. The compressor will run hot and finally seize if there isn’t enough refrigerant. 

Evaporator coils

Using a series of air ducts, evaporator coils collect heat from the air and return it to the house as cool air. Although coils might corrode, they only need to be serviced every three years if they are kept inside.

Condenser coils

Because the compressor and condenser coils are outside, they can become dusty due to the weather. Once a year, they can typically be cleaned with a water hose, but an HVAC professional will have to use a chemical cleaner to clean them if they become too unclean.

Worn contractor

The compressor, blower motor, and condenser fan motor all have contactors in an air conditioner. They connect the motors and compressor to an electrical source, which turns them on. When the contactor arcs and pits, it becomes difficult for the electric current to activate the motors.
