Air Duct Cleaning questions, answered by experts

While you can attempt to remove mold from ductwork using a mixture of water, baking soda, and laundry detergent, flexible ducts are fragile and may tear when you scrub at the mold to remove it. If you suspect mold is growing in your flexible ductwork, it’s best to contact a professional for help.

Some homes in warmer locations have air vents in the ceiling because they do a better job of cooling than floor vents. This is because hot air rises and cool air sinks. Homes located in cooler climates tend to have vents in the floor because they do a better job of delivering warm air, which rises.

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to:

Changing filters
Checking the thermostat
Clearing away dust and debris
Checking for mold
Inspecting electrical elements
Inspecting condensate lines and drain
Cleaning evaporator coils
Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.
