If you don’t have a proper system at your home to stop unnecessary air leakage, you may suffer extra expense on your annual budget. Usually, the homeowners tend to do a lot of things to cut the cost to the possible extent. They use energy savers instead of standard bulbs or tube lights and prefer to buy energy efficient appliances so to consume less power. But they do not make any arrangement for blocking the air leaks at their house and ignore the most crucial factor. Saving your home from air leakage can save 30% of your energy consumption.

Air can find its way from tiny spaces that are entirely unexpected. Most houses are permitting air leakages without the knowledge of their owners. As a result, they cause the electrical appliances to use more electricity, increasing the regular expense. This air leakage may also affect the quality of air inside the house and bring in unwanted odors and temperatures.

To avail the maximum benefit from your appliances, check your house for air leakage. Here are some common air leaks that are to be tested thoroughly:

Roughly installed ducts:

The ducts of your HVAC system are most prominent part of your whole system as they conduct the air in and out of your place. But if these ducts are not correctly installed and some space is left around them at the time of fixing them in the walls, they tend to cause air leakages. These air leakages not only disturb temperature control but also lead to unwanted expenditure.

Check your ducts for such air leakages and inspect them thoroughly. Use sticky metal tape to cover the gapes created by the duct installation. You may also use mastic but avoid non-adhesive duct tape for the purpose. Carefully block the air coming from the branches of ductwork.

Unsealed Windows and Doors

Windows and doors can allow more air and water leakages than anything else at your home. Plan a close inspection of your doors and windows. Check for tiny holes in the windows and invisible cracks in the doors. Also, check that the doors are not leaving any extra space at their bottom to let the air pass through them. Sometimes the doors have loose thresholds, and they do not properly fit in their frame. Such doors may lead to continuous air leakage. Make sure that doors can adequately shut the air outside your room so that you may get the desired temperature without being costly. If required, replace your windows or doors to avoid any problem.

Attic Air Sealing

Look for gaps and holes in the ceilings from your house attic and make sure the fans and bulbs in the roof are not giving way to air. Silicon caulk or acrylic latex can be used to cover the air coming from the fan and other electrical connections of your house. Each link can be a passage of air so do not ignore any of them considering them minor spaces.

Recessed Lighting

Recessed lighting gives your house an elegant and modern look, but it also brings its disadvantages. These lights are likely to absorb air from outside and become passages of air from the floor systems. You can use smoke sticks to check for air leakage due to these lights. Once the air leakage is confirmed, you can use caulk, build a soft fit box, enclose the recessed light or replace the recessed light if it is not getting improved.


Chimneys are a fundamental need in the modern houses and on the other hand, they are a dangerous outlet for air and many unwanted insects or germs. Moreover, careless building process may lead to problematic holes around the chimneys. Discover these kinds of gapes around your chimneys and cover them with aluminum flashing that is accurately fixed and are positioned with high-temperature caulk.
