Why Is My Air Conditioner Not Cooling My Home?

Why Is My Air Conditioner Not Cooling My Home?

As the summer months approach, issues with air conditioners become more common. Long winters and improper care can lead to sub-par cooling and higher energy bills. If your house is warm despite the air conditioner running, you may be in need of professional help.

Most commonly, air conditioners are not cooling properly because they are lacking air flow. Leaves, dust, and other particulates can clog the evaporator coils and cause issues with cooling. While you can clean and replace the filter, it is best to contact A-Plus Quality for HVAC services in the Greater Toronto Area to properly restore the unit to working condition. 

Another common issue is damage to the fan or fan motor. The fan is responsible for moving the air across the evaporator coils, and if it is running too slow it can form ice buildup. A buildup of ice can damage the motor or cause it to partially lose its power from the supply. The best option is to contact A-Plus Quality, HVAC services in the Greater Toronto Area, if you believe your motor is damaged as a certified technician will need to assess the flow of electricity.

The last common issue is damage to the thermistor. This component measures the temperature of incoming air and signals the main control unit to power on or off. If it is damaged or becomes defective, it will not properly turn on the circuits when the correct temperature is reached. The thermistor is a wire-like device normally located near the coils. First, check to see if there is any visible signs of damage or wear. If the thermistor looks damaged, it can easily be removed and replaced. 

Generally, most repairs to an AC unit will need professional help to ensure its proper care. With a the help of a licensed professional from A-Plus Quality, HVAC services in the Greater Toronto Area, your AC unit will operate properly for years to come. If you need your air conditioner maintained or repaired, contact us today.

FAQ

  • 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.

  • 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.  

  • 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”.
