Six Causes Of AC Odor

Six Causes Of AC Odor

Have you noticed a foul odor in your home that only gets worse when your air conditioner is running? These unpleasant odors may not only be an inconvenience, but a hazard to your health. Here’s some useful information on identifying the causes and solutions for common odors that run through your air conditioning system.

THE 6 COMMON CAUSES OF AC ODOR

1) MOLD/MUST/MILDEW

Mold gives off an unpleasant stuffy odor that’s easily recognizable. Excess humidity or moisture in your HVAC system is the most common cause of mold and mildew buildup. To prevent this, keep an eye out for water leakage, drainage issues, and frequently replace HVAC filters. The most effective method of reducing mold buildup is to install a whole-home dehumidifier. One that connects directly to your HVAC system automatically removing the moisture from the air that would create mold.

2) SEWAGE

If your P-traps are dry, sewer gases can creep up into your home. To prevent this, run the water in all of your sinks monthly to ensure there’s a good supply in each trap. Dry P-traps are an easy problem to solve, and if the smell persists, it may be due to a larger issue. Other causes include backed-up sewer lines or ruptured sewer vent pipes. If you suspect this to be the issue, contact a professional plumber or HVAC technician immediately.

3) SULFUR

Sulfur smells like rotten eggs and cannot be ignored. Occurrences of this smell could be the result of a gas leak. Natural gas is a common energy source, but it is odorless and therefore extremely dangerous in the event of a leak. Manufacturers of natural gas are required by law to add mercaptan, a chemical that emits a distinctive odor, like rotten eggs. Another sign of a gas leak is the browning of plants in the house.

If you suspect there’s a gas leak in your home, don’t operate and electrical equipment or create and flames. Evacuate the house immediately and contact the gas company to solve the problem.

4) BURNING

Burning smells are usually a result of an overheating motor, mechanical issue, or wiring malfunction. The first thing you need to do is turn off your HVAC system before the situation gets out of control. Contact an HVAC contractor to fix the issue. If the burning smell doesn’t subside, evacuate the house and call the fire department as there’s likely a fire in your home.

5) CIGARETTE SMOKE

If someone in your home smokes cigarettes, the odor could accumulate in the filter or evaporator of your HVAC system. You could smell the odor of a cigarette long after it was smoked in your home. Be sure to change the filter or schedule a professional cleaning with Renown Air Conditioning, the best HVAC contractor in Deltona.

6) ROTTING CARCAS

Sometimes small animals like squirrels can make their way into your HVAC system and get trapped. There’s nothing worse than the smell of death lingering around your home. If you suspect this is the case, shut off your HVAC system immediately and open some doors and windows for ventilation. Then, contact an HVAC contractor to remove the dead animal safely.
