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.

  • 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!

  • Most common Boiler Issues

    - Boiler fails to ignite
    - Low pressure
    - Strange Noises
    - Boiler is not responding to the thermostat
    - Cold Radiators
    - Boiler leaking or dripping
    - Boiler cycling very fast
    - Available Hot water but No Heat

  • 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
