Is It Safe To Use A Pressure Washer On My Air Conditioner Unit?

Is It Safe To Use A Pressure Washer On My Air Conditioner Unit?

Preparing your HVAC system for the winter in the autumn can save you from discovering that your heating system isn't operating during winter. Additionally, this guarantees that adjustments are made to keep your system functioning effectively.

Can I Pressure Wash My AC Unit?

One of a home's most expensive appliances is an air conditioner. Owners might therefore want to clean it to safeguard this investment.

A unit covered in dirt won't function well and is more likely to malfunction. Therefore, many AC owners try to clean the coils to prevent damage and energy waste. A pressure washer might seem the best choice due to how well dust and mildew are eliminated by its powerful force. Unfortunately, the coils in your unit won't benefit from it.

A pressure washer will exacerbate the situation by harming the fins due to intense strain, which makes these metal components flex. This might potentially result in damage to the tubes. AC coils cannot withstand the force of a power washer. A Plus Quality does not recommend using the pressure washing machine to clean your AC unit.

The Distinction Between Condenser And Evaporator Coils

The condenser and evaporator coils are two critical parts of cooling systems. The heat transfer process depends on the evaporator and condenser coils. The two are typically made of copper, which makes heat transfer simple. Also, they frequently have vanes or fins that expand the surface area for heat transfer.

The condenser coil absorbs heat from the indoor air and transfers it outside, whereas the evaporator coil cools the indoor air by removing heat and moisture.

Cleaning The Interior Air Conditioning Unit

Regular cleaning is required for the dust filters in the interior air conditioning unit. The harder the air conditioner works to push air through the filter, the more clogged the filter is. Consequently, operating expenses can increase.

Simple steps for cleaning include pulling out the plastic cover and removing the filters for a thorough brush or shake. For a deep clean, they may also be vacuumed. Also, you may wash the dust filters in warm water with some mild detergent and rinse them clean if they are filthy and soiled. Before re-entering the unit, make sure they are thoroughly dry.

Cleaning Your Outdoor Unit

The performance of your unit may deteriorate if the outside unit is damaged or affected by dirt and debris. Therefore, it's crucial to ensure the fan and grate are spotless and debris-free. It's important to cut off the energy to your system before cleaning the appliance.


Cleaning your air conditioner regularly is important, but using the incorrect tools might harm your system. Consequently, if you are having trouble cleaning your cooling system, contact A Plus Quality Heating and Cooling to benefit from dealing with reputable HVAC specialists in Toronto and GTA.

  • 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.

  • 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”.

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • 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
