What causes low airflow in my supply registers? When you use your air conditioning the heat removed from the air causes the air to become dense and harder to move. These are some things to look at to make sure the air flows good in your home or office. First lets make sure we replace that old air filter with a new one and use a good quality air filter if you have air conditioning this will prevent the dirt from going into the evaporator and plugging up the coil. I like to start at the furnace or FAU and work my way around the home. We want to unplug the unit and remove the panels looking at the blower motor and blower wheel this is important that you clean both and make sure the dirt is not in the veins of the blower wheel. I use co2 and blow out my wheel and motor. You can use compressed air or a brush and vacuum to clean the wheel. Some times you might have to pull out the assembly and this is easy and can be done yourself without hiring an air conditioning contractor. Next thing is we will move up to the evaporator coil mounted on top of your furnace or FAU remove the panels and clean the fins with care not to bend or destroy them. After brushing down the evaporator coils we can either blow them out or use a vacuum to get the remaining dirt off it. I like to use a self-rinsing evaporator coil cleaner on the inside part of the evaporator or A coil. Put all your parts back together and plug the FAU back in. Go to your thermostat and lets turn the fan switch to the on position. We will now go back to the furnace or FAU and feel for air leaks! This is really important that each and every leak be sealed you can use duct tape at every leak forcing the air into the ductwork. Next thing we will want to do is go into the attic while the fan is still on and check each of your duct runs and connections. I have found so many air leaks in ductwork causing the loss of efficiency and this is your money going right out the door! Use the duct tape to make repairs on all the air leaks in your attic. Air always wants to take the pass of least resistance so make sure all air leaks and loss are repaired. You can also find new flex ducting at home depot and also your favorite hardware supply store. Following these procedures as I described will save you money on your air conditioning electric bill this summer and keep your home cool and comfortable.
