Winter months can be tough, especially when undergoing a much-needed home renovation. The cold weather certainly doesn’t help in speeding up the process. As such, it may be a better idea to begin winter preparations early, while the weather and temperatures remain bearable. Besides researching the price of a heated driveway, it is wise to consider maintaining your exterior vent covers.


What are Exterior Vent Covers?


Exterior vent covers are useful all year-round. But these components really shine during winter. Exterior vent covers help remove heat and moisture build-up from your home’s vents. This helps to relieve pressure from your home’s ventilation system and minimize the risk of damage. Essentially, exterior vent covers work in conjunction with your home’s overall ventilation system to ensure that warm air is properly redirected to areas that need it the most.

Caring For Your Exterior Vent Covers


As your HVAC unit’s first line of defense, exterior vent covers undergo a significant amount of erosion due to the natural elements, wild animals, and more. These covers are prone to collecting filth, grime, dust, and hair, and as such should be cleaned regularly. While more modern iterations come complete with self-cleaning and antimicrobial features with improved dust guards and more streamlined designs, most traditional wood, plastic, and metal covers still require a good scrub.


If your exterior vent cover is not dishwasher-safe, consider conducting monthly wipe-downs with any mild floor cleaning solution.


How To Replace an Exterior Vent Cover


If regular cleaning won’t save your inefficient exterior vent covers, it may be time to consider replacing them. Thankfully, the process of replacement is much easier than finding the best cover for your home.



Using the materials and tools listed below, here is how you can replace your exterior vent covers without professional help:


Step 1: Start by removing the old vent. Use a scratch awl to scrape off any paint that is covering the screws. This will give you uninhibited access, and enable you to remove the vent without damaging the area.



Step 2: Most exterior vent covers are surrounded by ductwork. These refer to the system of metal or synthetic tubes that transport air from heating, ventilation, and air-conditioning (HVAC) equipment throughout your home.



When removing an exterior vent cover, it is important to access if the ductwork extends out from the wall. This may cause issues when trying to install a flush-mount vent cover. Therefore, you will need to cut away the excess ductwork with lineman’s pliers. Remember to wear safety glasses and heavy work gloves, and protect the wall around the vent using painter’s tape.



Step 3: Once all excess ductwork is removed, peel away the painter’s tape to make room for the new exterior cover vent. To fit your new vent, simply slide the cover into position and secure it with screws. Always ensure that the louvers are facing down. If needed, use your scratch awl to carve out points for your pilot holes before drilling.



Step 4: Start screwing first with your hands before transitioning to a screwdriver. Test the vent to ensure that it functions properly at every step. Lastly, if needed, run a bead of caulk along the perimeter of the frame to seal it.




This concludes our article on the best exterior vent covers for your home during winter. Many of the items on this list, can be used all year round, and provide other benefits such as pest deterrence and UV resistance. They are also extremely easy to install.
