Do I Need To Cover My AC In Winter?

Do I Need to Cover My AC During Winter?

Winter has made its way to Canada, leading homeowners to start winterizing their homes and preparing to cover their AC units. The question is whether this task is necessary. Modern AC units can hold up against harsh winter temperatures. However, there are still some benefits to covering your AC to consider.

Pros of Covering Your AC During Winter

Cold temperatures are not the only potential threat to your AC in the winter. You also have to consider the following:

Debris
As the weather changes, leaves, sticks, and limbs fall from above. These items as well as dirt and yard waste can land in or be blown into the unit. Since the unit is not in use, these all have the opportunity to settle and impact your AC’s efficiency when it’s time to turn it back on. Using a cover prevents debris and waste from entering the unit, keeping the coils cleaner and reducing the potential damage.

Water
When it rains, the water can fall into your AC unit and freeze on your coils. This can potentially render your unit inoperable. Covering your AC unit can help keep the water away from your coils.

Cons of Covering Your AC During Winter

Since there are always two sides to every coin, there are several cons to covering your AC unit. The biggest is that covering it blocks airflow, trapping moisture inside the unit. This can lead to rust, corrosion, mold, and electrical difficulties.

Additionally, remember that humans are not the only living creatures that seek warmth and shelter in cold weather. This means that mice and other creatures might make a home in your unit, resulting in chewed wires and insulation.

Choosing The Right Cover

Covering your AC is not mandatory. However, if you decide to cover it, you want to pick the best cover for the job. Those made from woven Polyester offer protection for your unit while allowing air to flow through.

Adding a cover to your AC isn’t the only way to protect it. It’s also essential to have it maintained regularly. For the best results, contact us to schedule your A-Plus Quality maintenance after the Holidays!

FAQ

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • What are mini-split advantages?

    Just as the name implies, a “mini-split” system is a “split system” however available in smaller capacities, for single room to whole house conditioning. Mini-split systems may range from as small as 9,000 BTUh per hour, comparable to say, a small window AC unit, for individual room use, up to 4 and 5 ton capacities for “Room By Room” (also known as “Zoning”) and whole house conditioning. With near universal design, mini-splits are “heat pumps” which provide both heating and cooling for a home. Here are key advantages when compared to traditional split systems:

    Efficiency- Mini-splits are highly engineered systems which offer attractive operating efficiencies, in many instances, eligible for utility company rebates.
    Heat Pump- Most mini-split systems are heat pumps, providing year-round comfort.
    Solar friendly- Due to very low power requirements, mini-splits are an ideal complement to “Net Zero Energy” homes, or any home using renewable power.
    Carbon footprint- Mini-splits are 100% electric, with zero operating emissions of any type.
    Zoning- Most mini-split manufacturers offer systems capable of room-by-room “zoning”, to account for peak demands of a room based upon construction type, exposure orientation and usage.
    Variable capacity- Mini-splits are typically DC inverter driven. That is, a variable speed compressor which modulates in proportion to instantaneous demand. Most conventional split systems, by comparison, operate with an ON-OFF strategy. (Would you use an ON-OFF switch as the accelerator in your vehicle?)
    Location, Location, Location!- Mini-split outdoor units are compact; they can be located far away from noise-sensitive areas, such as bedrooms and home offices. Mini-split indoor units have the ability to be installed where conventional systems cannot.
    They’re perfect for additions and remodels where access to current HVAC system is difficult to access.
    Modern mini-split systems are remarkably quiet; in fact, many times their operation is unnoticed by the end user.

  • Why is there ice building up on the copper pipes?

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337

  • Furnace is blowing cold air in Winter?

    This can be due to Ignition lockout, sometimes could be resolved by resetting the power  and if this does not resolve the issue you should contact a certified gas technician from A-Plus Quality to get this problem resolved!

  • What is a heat pump?

    Heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances.
