When you switch on the AC unit and are overpowered by a musty smell, this is a sign for a serious issue. Before scheduling an air conditioner repair service, understand the top 5 reasons why your AC unit could be smelling and how Aire One Heating and Cooling, serving Newmarket, Keswick, Aurora, Stouffville, King City, North York and other surrounding areas across Southern Ontario, can help:
1) Excessive Moisture
When moisture builds up inside air ducts and vents, it can lead to an odour. If the smell becomes apparent only when it is turned on, then it is likely there is a chance of mold and mildew located in the ductwork.
2) Wrong AC Unit Size
For your unit to work properly, it needs to be the right size for the room. If the unit is too big or too small, it can create a moisture problem. Consulting with our specialists at Aire One, providing heating and cooling services in Aurora, Keswick, Newmarket, Stouffville, King City, North York and other surrounding areas across Southern Ontario. Our HVAC technicians can help ensure that your air conditioning unit is the right size for your home.
3) Full Drain Pan
Moisture that is removed from indoor air causes water to fall into a drip pan. It can over time accumulate mold, which can be pumped into the air conditioner unit and cause the smell. Scheduling an air conditioner repair service with Aire One Heating and Cooling to have an HVAC technician come check the drip pan can keep this from being the source of your problem.
4) Frozen Evaporator Cells
It is important that the free-flowing air the unit uses is clean. Dirt and debris can block airflow, causing water to collect on the evaporator cells and freeze the coils. This is another reason why scheduling an HVAC maintenance appointment with Aire One Heating and Cooling can help eliminate this problem.
5) Blocked Condensation Line
A condensation line is a PVC pipe located outside the home. It drains the water from the drip pan to the storm drain. It is also one of the locations for mold, mildew, and sludge to build up because of its small size. If this issue occurs, contact us today to schedule an air conditioner repair service with Aire One Heating and Cooling, serving North York, Aurora, Keswick, Newmarket, Stouffville, King City and other surrounding areas across Southern Ontario.
