What’s the main culprit behind hot spots in your home? Usually, it’s inadequate indoor airflow. So how do you get rid of them?
Mason BPP, a local home efficiency company, explains in this post.
The Two Main Causes of Inadequate Airflow
There are two possible causes of inadequate airflow: issues with your home’s structure (e.g., not enough insulation, inefficient windows) or problems with your HVAC system’s ductwork. Insulation and energy-efficient windows are supposed to prevent heat transfer, while a properly-installed ductwork system should be able to distribute cool air evenly throughout your home.
Getting Rid of Hot Spots
If you notice hot spots in your home, try:
Having your insulation inspected – It’s possible your home doesn’t have enough layers insulation or the insulation’s R-value—which gives you an idea of the insulation’s ability to prevent heat transfer—is below federal requirements. The insulation requirements for each area depends on the climate zone in which they’re classified. For instance, California is classified under Zone 3, which means floor insulation must have an R-value between 19 and 25, while uninsulated attics should have insulation that has an R-value between 30 and 60.
Getting your HVAC system checked – Dirty air filters and vents can hamper the flow of cool air, not to mention significantly lower indoor air quality. It’s a good rule of thumb to have your HVAC system inspected by a professional technician at least twice a year. If you want to improve your HVAC system and your home’s energy-efficiency, it’d be a good idea to schedule home energy audits every year or so.
Checking if there are air vents that are blocked – There shouldn’t be any furniture near air vents.
Checking the window sealing – If the seals on your windows are damaged, heat can enter your home and create hot spots. Here’s a trick for detecting air leaks: close all the windows and doors in your home and light an incense stick near your window. If there’s an air leak, smoke should drift toward your window.
