How To Find Leaks And Seal Them
October 1st, 2018 by cverdone
Your Heating Ventilation and Air Conditioning (HVAC) system is in your home to provide ideal temperatures, so you could comfortably live even when the external environments are not so friendly to us humans.
We as homeowners would, of course, appreciate it when our equipment is performing well and effectively. It would then be safe to say that we and our HVAC are at the same side of the fence with a common goal, so it would only be right if we helped them out so that they could do their jobs better.
Many are unaware that our homes can have many places which can be a source for air leaks. These are gaps or crevices that are often unintended and allow coldness or warmth provided by our system to exit. Those that find their way out would have helped your units as needed temperatures would have been easily met and maintained if these had only stayed inside.
These cause your AC and furnace to work harder and longer than needed, increasing wear and tear and consumption of electricity and gas. Both of these effects would result in more money being paid and wasted as this could have been prevented.
Actually pinpointing where these are is tricky and will require a little creativity. Eyes alone won’t suffice as you probably won’t be able to find all of them solely through visual abilities.
You won’t be feeling for openings. On a windy or cold day with your heater turned on to warm up your place. Bring your hands close to different spots where you suspect there is a leak. Windows and doors most likely have more than one. If you feel cold air coming in, then there is a crevice which you’ll have to deal with.
This is best done with wet hands as they become more sensitive.
Depressurize your home by closing all doors and windows. Shut down your HVAC and instead turn on all your exhaust fans in the kitchen and bathrooms. Light the incense and move it near places where you think leaks are present. An indicator will be if it’s blown inward or pulled outward.
Blower Door Test
A professional will handle this and will use a blower door to pull the air out of your home. They will then proceed inside to spot where the air is flowing from, which will be coming from leaks.
If your lights are labeled with ICAT, that means they are already insulated, and any further action won’t be necessary. If not, then an airtight baffle can easily handle this. Fit this into the housing then you are ready to go.
For gaps that are a quarter of an inch or smaller, then caulk would be best for this. These are inexpensive too.
Windows and Doors
Use weatherstrip for leaks in these parts. A door sweep should be used to block out drafts coming from below a door.
It wouldn’t hurt putting in a little work to aid your HVAC so they can better serve you. This will, in turn, benefit you a lot anyway in the long run, so why not get to it? If you find it too much of a hassle, then hire technicians or contractors to get this done. Call us, Thornton Heating, at (847) 905-1608. We’d be happy to take it off your hands.
