We’ve all been there. You haven’t been using your air conditioner during the cooler months of the year, and when you finally turn it back on to cool down the house again, you’re met by some very strange smells.
It’s important to know what the different odors mean and how to take the proper measures to remedy any issues that are causing these HVAC smells.
A rotten egg smell from your HVAC system could be a natural gas leak. Natural gas is odorless, but the sulfur in it gives off a foul smell when it mixes with the air. If you smell natural gas, turn off all ignition sources and leave the house immediately.
If you need help determining whether or not you have a natural gas leak, contact your utility company. If they confirm that there’s no leak, you can call us to inspect your HVAC system.
Sewage smells are caused by the foul gasses from fractured sewer lines. These odors can come from your HVAC system when installed has been installed near a sewer line. The smell may have lingered into the supply ductwork.
The smell can sometimes be powerful, depending on how close you are to the sewer lines and how much sewage has backed up into them. This is why you may smell sewage coming from your AC unit: Your system is close enough to have these gasses waft into your home through your vents.
If this happens, get in touch with the professionals needed to find and eliminate the problem. Plumbers and HVAC technicians are the best people to call.
A dirty sock smell coming through the HVAC vents is a telltale sign that you need to clean your air conditioner’s evaporator coil. This part of your HVAC system cools and dehumidifies the air before it enters your home.
Mold can cause health problems, especially if it grows inside ductwork where people breathe in the released spores. It’s best to leave this type of job up to professional HVAC contractors who have experience cleaning out mold from inside units and ductwork.
The smell of musty air is usually a sign of a problem with your HVAC system. It can come from several different places in the system, so it’s important to find the source of the smell and fix it.
If you can smell an electrical odor when you turn on your AC unit, the problem may be in your air filter or blower motor. Your air filter should be changed every three months during the summer and once a year during the winter. If your filter is dirty, it will restrict airflow and cause your system to work harder to cool your home.
The smell of oil in your home isn’t uncommon, especially if you have an older heating and cooling system. The oils inside your system lubricate parts like compressors and motors and provide insulation for electrical wires.
