Steps for Shutting Down Your AC Unit and Winterizing It

Steps for Shutting Down Your AC Unit and Winterizing It

Fall is here, and air conditioners across Washington are seeing decreased usage. In a week or two you’ll want to shut down your AC unit completely and prepare for it winter. Day & Nite Plumbing & Heating, the preeminent AC company serving Lynnwood, WA, offers these steps for shutting down your system and prepping it for the cold days ahead:

Step 1: Make Sure to Shut Off the Unit, Not Just the Thermostat

It’s a common misconception that switching your thermostat from “cool” to “off” will shut down the AC unit. But in order to fully deactivate the unit, you need to go outside and turn off the AC circuit next to the AC system itself. This small step is actually a big deal, because an AC system that isn’t turned off can collect water/moisture during the winter on unseasonably warm days. When the temperature reverts back to standard winter chill, this water could freeze inside the AC unit and cause damage.

Step 2: Give Your AC Unit a Thorough Cleaning

After the system is shut off, grab your water hose and wash the system thoroughly. You’ll be surprised how much stuff collects in an AC unit over the course of a summer; dust, leaves, bugs, and other snips of nature are all liable to come streaming out of your system. Next, if your AC unit is near your shrubbery, give those shrubs a trim – and while you’re at it, check the unit for twigs and branches and remove any that are stuck. Lastly, wait for the unit to dry completely before winterizing. If you winterize while there’s still water inside, this could lead to rust, which could wear out the unit faster.

Step 3: Insulate the AC Unit’s Pipes

Insulating the AC unit’s pipes is essential for preventing cracks or breaks over the winter. Wrap the pipes in foam covers, use duct tape to secure the insulation, and enjoy the peace of mind that comes with knowing your pipes won’t freeze when the temperature plummets.

Step 4: Cover the Unit

After you address the pipes, the fourth and final step is to insulate the unit itself. Don’t cover this step until the unit is turned off and you’re ready to hunker down for winter. Covering a still-active AC unit is a recipe for trouble. For the cover itself, we recommend a vinyl or waterproof plastic cover made snug with bungee cords. Check the cover periodically, and regularly remove any snow, leaves, or branches that collect on it. On warm winter days when you want to run the AC for a few hours, remove the cover before turning the unit on.

Selecting the Right Furnace: The Factors You Should Consider

Selecting the Right Furnace: The Factors You Should Consider

Thinking about a new furnace? If so, there are some important factors to consider before purchase and installation. At Day & Nite Plumbing & Heating, Inc., we have decades of collective experience with every type of furnace imaginable. Here’s some advice from us on how to select the right furnace.

Are some furnaces superior to others?

Absolutely. Efficiency is of course the biggest measuring stick that differentiates one furnace from another, but there are other important features your new furnace should possess. These include corrosion-resistant heat exchangers, pressure switches, induced draft blowers, direct-drive blower units, and, to minimize noise, an insulated blower compartment.

Another way to weed out good furnaces from great is to review the furnace’s limited warranty. As with any product, a trusted manufacturer will have no problem backing up its craftsmanship with a rock-solid warranty. And speaking of the manufacturer, you should also confirm that tests and quality checks are performed on each furnace before it leaves the manufacturer’s plant.

Does size matter?

When you shop for the perfect furnace, you’ll want to ensure that the size of your home aligns with the furnace’s heat output. This heat output, in turn, needs to integrate flawlessly with your home’s ductwork to guarantee the right amount of hot air is funneled through the system in order to provide consistent heat. A furnace that’s too small won’t generate enough heat, and a furnace that’s too big will waste fuel (and money).

Just how important is efficiency?

If you’re like most American homeowners and are looking for ways to shrink your carbon footprint while saving money, then finding an efficient furnace is critical. Here’s one way to look at it: furnaces from decades ago only operated at a 30% annual fuel utilization efficiency (AFUE), meaning that only 30% of every dollar spent on heating was actually well-spent. The other 70% was wasted. As technology advanced, furnaces 10 – 20 years ago approached a 75% - 80% AFUE. Today, the most efficient furnaces boast AFUEs of 90% all the way up to 98%, incorporating the latest advancements to maximize your investment and significantly reduce your monthly heating bill. Some of the most important advancements are:

  • An electronic ignition instead of a continuously burning pilot light
  • Two-stage valves to control fuel flow. These ensure that the furnace runs high when first turned on and then reduces its run-rate to maintain a consistent temperature.
  • A programmable thermostat that allows the homeowner to customize the home’s heating cycle, thereby reducing monthly cost

What traits do all quality furnaces share?

Regardless of the manufacturer, the highest-quality furnaces share many of the same traits. These include:

  • High efficiency
  • Low maintenance frequency and cost
  • Dependability
  • Reliability
  • A warm, comfortable home all season long
