How do I make my AC blow harder?
Solutions:
- Turn off the unit so that it has a chance to thaw the ice build-up.
- Change the filter (if you haven’t already).
- Open and unblock any supply vents and return grates (the metal slots that blow and suck in air respectively).
- Call an AC tech to check your refrigerant level, evaporator coil and blower.
How do I increase the airflow in my central air conditioner?

- Clean fan blades.
- Inspect & adjust motors.
- Inspect your ductwork for blockages or leaks.
- Clean coils.
- Inspect your HVAC design and recommend modifications.
Why is my AC not blowing strong enough?
Problems like a fan clogged with dirt, a dead motor, a loose fan belt or a stuck wheel can all cause your blower to not work properly. These problems can keep the blower fan from blowing enough air out of your vents to keep you cool. Your evaporator coil needs air to blow over it to complete your AC’s cooling process.
Why is my AC barely blowing air?
Another reason your AC may be unable to blow a strong stream of air may be due to a frozen evaporator coil. There are two reasons why your evaporator coil may freeze. Either there is something restricting airflow over the coil, like dirt in the air filter or a blower that’s on the fritz, or you have a refrigerant leak.
How can I force my cool air upstairs?

- Inspect your ductwork.
- Check your insulation.
Should flex duct be pulled tight?
Flex duct should pulled tight to reduce inner air resistance. It should be supported with straps that are a minimum 1.5″ wide. The straps need to be spaced no further than 5 feet apart, but closer is better. Local codes or manufacturers instructions may specify shorter intervals.
