You’re relaxing at home and taking a breather after a long, demanding workday. Suddenly, you notice smoke spilling from the nearest vent. “Why is my air conditioner blowing out smoke?” you exclaim, jumping up from the couch.
Happy Camper Heating Air And Plumbing recommends that you immediately contact us about AC repair in Fullerton, CA. Smoky appliances can be dangerous and we’ll explain why this might happen below.
Are You Sure It’s Smoke?
What you see pouring from the vents or from around the equipment may not be smoke. It could just be air conditioner mist. Sometimes, your system produces excessive condensation when it doesn’t receive the air conditioner maintenance it needs. Let’s go over the reasons why condensation spills into your living spaces below.
Cold, Dry Air Colliding With Warm, Moist Air
Some airflow restrictions and other system inefficiencies can cause the cool, dry air your equipment produces to mingle with damp, hot air. This HVAC condensation issue may result in thick, white, foggy mist spilling from your vent openings. It looks more alarming than it usually is.
If you don’t smell smoke, try turning the cooling system off for a few minutes. Then, change your filter and make sure no furniture blocks the vents. These habits, paired with consistent tune-ups, should keep this phenomenon from recurring.
Drainage Clogs
Most HVAC systems have a small drainage system installed under the indoor unit. The drainage system catches condensation as it becomes a liquid, so it can drain outside. The condensation may stay in a gaseous form if the drainage system develops a clog.
The mist will then spill out from around the indoor unit, causing an alarming sight. Your HVAC technician in Fullerton, California, can unclog the drain line and get the water flowing again.
Moisture Buildup in the Heater Box
“Why is my air conditioner blowing out smoke?” The white smoke from vents in your home may be caused by the heater box housing too much condensation. This box contains your cooling system’s most essential components. The condensation likely originates from a blocked condensate drain, but the foggy gas finds a different outlet.
Why Is My Air Conditioner Blowing Out Smoke?
“But I can smell burning odors every time my system runs! Why is my air conditioner blowing out smoke?” If you can smell burning or smoky odors, it’s almost certainly because of actual AC smoke rather than water vapor, which is typically odorless. Real smoke coming from heating and cooling equipment can mean one of the following:
Electrical Problems
If the burning smell has a rubbery, metallic twang to it, it might be an electrical issue. Wire casings are made of rubber, while electrical contacts are metal. You might notice smoke emanating from air vents, depending on where the ignition occurs. This is incredibly dangerous and warrants shutting down the system until professional help arrives.
Overheating System
Metal-scented burning odors coupled with smoke billowing from the unit itself might mean the system is too hot to function. This can happen because of excessive usage or friction generating heat that gets trapped in the unit.
Turn your air conditioner off and contact a technician in Fullerton, California. Once your unit is fixed and able to cycle again, consider more moderate usage habits and consistent maintenance to prevent system overheating from recurring.
Motor Burnout
Every appliance and device has an expiration date, and your air conditioner is no different. Each component gets a little closer to breaking down with each passing year. The motor typically works the hardest and uses the most energy.
If a motor part catches fire, it’ll produce a foul-smelling smoke directly from the unit. The AC burning smell will gradually permeate the building. You’re better off moving forward with a replacement service under these circumstances.
HVAC motors can cost thousands of dollars, and a burnout typically signals the end of the line for the rest of the system. The only scenario in which motor replacement might be more cost-effective is if you installed the whole system within the past few years. Then, the situation might be a fluke, and your warranty may cover the service costs.
