Why Does My Air Conditioner Smell?

Why Does My Air Conditioner Smell?

Two units of an air conditioner work together to cool the temperature. The first is an indoor unit fitted inside the room for blowing and sinking air, and the second is an outdoor unit with a fan motor and cooling circuit.

If your air conditioner releases an unusual odor, contact a professional to get it checked. Different smells can indicate a fault in different components of your air conditioning unit.

Reasons Why Your Air Conditioner Might Smell

There are various reasons why your air conditioner might release a weird odor. Getting it checked can help you save money from further repairs. The type of smell coming from an air conditioner is explained as follows:

Electrical and Burning Odors

These smells indicate mechanical failure in the air compressor, fan, electrical short circuit, or wiring-related problems. The parts are made up of various chemicals and metals.

You must be careful about the burning smell that comes out because it might cause respiratory issues. Contact the technician from air conditioning repair in McKinney to resolve these problems immediately.

Musty Odors

Musty smell like feet or dirty socks indicates an accumulation of water in the drain pan, or the problem in the evaporator coil causes bacteria buildup in the evaporator coil.

It may also give rise to fungus. Musty odors can indicate immediate repairs your air conditioner might require. Contact professional air conditioning services in McKinney to avoid any major repairs.

Refrigerant Leakage Smells Like Chemicals

Generally, if there occurs a chemical-like odor, seek professional help. This smell is generated frequently after turning on the AC and stays for a longer time.

It may be due to refrigerant leakage as gas leaks pass from copper coils. A broken air conditioner consumes more electricity causing higher bills. Contact us for AC replacement in McKinney, TX to avoid any major AC repairs.

Gunpowder Smell

Gun powder smells are also like the smell of electrical or burning type. If there occurs some burning in electrical circuits or fans motor board, this may happen and needs some serious attention to repair. Contacting an HVAC technician to sort the electrical issues might be a good idea.

Rotten Egg Smell

Usually happens in winter. Such type of problem is due to dead animals and pests. Any small animal stuck in the machine or duct area will leak or generate very bad and dangerous odors, so you need to keep them away and keep your machine regularly serviced.
