Preparing Your Home for Winter: A Checklist

Summer's warmth is now a fading memory and the inescapable and important task of winterizing your home before the first big freeze looms. Luckily, we've created a checklist of many things to consider before that first snowfall


Winterizing your home is no fun when it is already 20 degrees Fahrenheit outdoors, and sleet is already falling. Even worse is having your sprinkler system burst from frozen lines because you didn't get around to purging the system before freezing weather set in.

Fall is the time to get winterized in preparation for the season. Proper winterization involves a systematic review of your home's HVAC equipment as well as the critical structural and mechanical systems. Take care of these elements before winter, so you can enjoy the snow in cozy comfort and not worry about your home. contact Scotia HVAC, for the one stop solution for all HVAC.

Winterize the Heating System

The heating system is perhaps the most critical element for a home in winter, and the time to check your furnace and other heating appliances is in the fall—no later than the end of October. Give your system a test run through and make sure all systems are operating.


Heating System Checklist


Test run: Turn the thermostat to heat mode and set it to 80 degrees, just for testing. You should hear the furnace turn on, and warm air should begin to blow within a few minutes. If the furnace is running fine, turn the thermostat back to its normal setting. If the furnace not running properly, you can try to diagnose it yourself.

Depending on what's wrong, you may be able to fix it yourself, or you may need to call a qualified service technician.

Seasonal maintenance: Either have the furnace checked by a service technician or do this work yourself. Most seasonal maintenance tasks are well within a homeowner's skill range.

Replace the air filter: Put in a new, clean air filter. It's easy, and doing so will ensure a free flow of air and a cleaner environment. Each furnace has its own requirements for air filters, so follow the manufacturer's recommendations. A monthly replacement of the air filter is usually recommended. Check fuel supply: If you have a propane or fuel oil furnace, make sure to have your fuel storage tank is topped off and ready to go.

Inspect and clean heating vents: Clear obstacles to heating vents, so air can freely flow. Many experts recommend having a service technician come in and clean the vents every year or two.

Check for carbon monoxide leaks: This silent killer can easily be detected with either an inexpensive test badge or battery-operated alarm. If you discover problems, call in a professional to identify and correct the cause of the CO leak. Usually, this involves leakage in the exhaust system of a furnace or other fuel-burning appliance, such as a water heater. Don't put this work off; a CO leak is a very dangerous situation.

Check exhaust vents: Some furnaces and boilers, as well as gas water heaters, vent through a chimney, while newer high-efficiency models may vent through plastic pipes running through a side wall. Make sure these vents are open and free of obstructions. A vent that hasn't been used all summer may have become home to birds or other animals, which can block the vent pipes and interfere with the furnace's ability to burn efficiently and properly vent exhaust gases.


Winterize the Air Conditioning System

Often neglected is one of the most important components of a cooling system—the condensing unit outside that churns away in the heat of summer. This component needs a little attention, too, as winter approaches:

Clean the condensing unit of debris: Using a hose with the spray-head set to the highest pressure, clean the fan blades and condensing coils clear of debris and dirt. Let the unit dry completely before covering it for the season.

Cover the condensing unit: Left unprotected, the condensing unit can be damaged by wet leaves and debris that contribute to rusting and freezing of internal components. Although these units are designed for outdoor use, covering them with a breathable waterproof cover made for that purpose goes a long way to extending the life and efficient performance of the unit.

Winterize window air conditioners: As for window air conditioners, remove them if possible and store for winter. Left in windows, these appliances are very hard to seal effectively against winter drafts. If they can't be removed, then close the vents and make sure to get an air conditioning cover similar to the condensing unit cover described above.


Inspect the Wood-burning Fireplace, Chimney, and Flue

Although largely ignored in warm weather, the wood-burning fireplace and chimney can be a major source of cold air leaks and other issues in winter. So the chimney and fireplace need some inspection and service before winter sets in.

Clear obstructions. Check to make sure the chimney is clear of any nests from birds, squirrels or other small animals.

Check the damper. Make sure it opens and closes fully, and that it is can be locked in the open or closed position.

Check the chimney draft. Make sure the chimney will draw up the fire and smoke properly. Test this by taking several sheets of newspaper and rolling them up. Then with the fireplace damper in the open position, light the newspaper in the fireplace. The smoke should rise up the chimney. If it doesn't, you have an obstruction and need to call a professional in to clean the chimney of creosote and ash and possible debris.

Have the chimney cleaned. If it has been several years (or never) since you had your fireplace chimney cleaned, have it done by a professional chimney sweep. This is not a pleasant DIY project, and professional cleaning is not very expensive.

Inspect the firebrick in the fireplace. If you see any open mortar joints, have them repaired immediately. A fire can spread into the stud wall behind the masonry firebrick through open mortar joints.


Winterize Water Pipes

Water supply pipes are especially susceptible to cold weather and freezing. Burst pipes from freezing can cause some of the most expensive repairs in the home. Water supply pipes are most susceptible to problems, but exposed drain pipes can also occasionally freeze. So it is important to systematically review the plumbing pipes in your home.

Insulate exposed piping: If you have any exposed water pipes in uninsulated spaces, such as in a crawlspace, attic, exterior walls, etc., make sure to insulate them—at a minimum with foam insulating sleeves. Ideally, you should wrap them with electrical heating tape first, then insulate them.

Exterior faucets: Known as hose bibbs or sill-cocks, the exterior faucets need to have their water supply turned off inside the house, and you also need to drain water from them by opening up the exterior faucets. You may also want to consider an insulated cover for the hose bibb. And remember to disconnect your garden hoses from the sillcocks or outside faucets, and drain them.

Seasonal shut-down: If you are shutting down a property for several months to leave for the winter, you should always shut off the water supply and drain the plumbing system. If a leak were to occur when you are not present, the damage could be catastrophic.

Review Insulation

Serious insulation upgrades are not something to do hurriedly right before winter. A home that is in serious need of more insulation should be carefully evaluated and the work completed carefully during warm months. But there are some areas you can easily insulate to help prepare for winter.


Insulate your hot water heater with an insulating blanket you can buy at the hardware store.


Insulate exterior outlets and switch plates with inexpensive foam sealing gasket.


Seal unused fireplaces. If you don't use your fireplace often and it leaks air, you can cut a piece of fiberglass insulation and stuff it into the fireplace behind your glass doors to block the cold air coming down the chimney. Of course, you need to remove this whenever you use the fireplace.
