Cooling towers

  • What is a cooling tower?
    What is a cooling tower?

    A cooling tower is a distinctive heat exchanger structure that removes heat from water on a massive scale. During operation, hot water comes in contact with the cold air, which cools down the water through evaporative and heat transfer. Cooling towers are designed as heat transfer systems, but contact between cold air and hot water also cools the water through evaporation. A cooling tower aims to cool hot water used by industrial processes like machines and HVAC systems.

  • How does cooling tower work?
    How does cooling tower work?

    Industrial processes and Air conditioning equipment can generate tons of heated water that need immediate cooling. The hot water is pumped through the industrial cooling tower, where it's exposed to cold, dry air. The heat from the water escapes through evaporation. The cold water then returns to the air conditioning equipment or other processes to continue its cooling function. The cycle repeats over and over again. In the cooling tower, water is passed through nozzles which spray water into droplets enlarging the water's surface area and creating a better chance of cooling down. Moreover, a fan on top of the cooling tower brings cold air from the bottom as the water droplets flow in opposite directions.

  • What is it used for?
    What is it used for?

    A cooling tower is a massive heat exchanger that helps to eliminate heat from commercial buildings, hospitals, schools, and industrial complexes. Cooling towers provide efficient and energy-saving operations for industrial processes that need cooling.

    A cooling tower is used to remove heat from a building or facility by shooting water down the tower and exchanging heat with the structure's interior. Air enters the tower from all sides and flows through the falling water. Heat is transferred when the air travels through the water, and part of the water evaporates. This heat and evaporated water generate a thin cloud-like mist that flows out the top of the tower. At the bottom of the tower, the cooled water is collected and pumped back into the plant or building for reuse.

    Cooling towers are important for industrial and cooling processes; otherwise, machines will break down, and safety can be compromised.


    In crossflow cooling towers, water flows vertically while air flows horizontally inside the tower. In this setup, water doesn't pass through the distribution system; instead, it goes to hot water basins to be installed on top of the unit. Thus crossflow tower is gravity fed and is out of the way of the airstream coming in horizontally. Moreover, the hydrostatic head of the water is the driving force behind the spraying nozzles. This gravity-fed setup is easily accessible and can be cleaned when operating from the top of the tower.

    Counterflow Cooling Towers

    Counterflow towers are set to allow the air to flow vertically upwards against the flow of falling water droplets. Unlike in crossflow design, it's impossible to open sealed gravity basins crossflow designs. Also, crossflow uses pressurized pipe spray systems, making them inaccessible during operations. Moreover, the pipes and nozzles must be further apart to allow air to pass through easily without restrictions. The counterflow system also needs pumps to maintain pressure and also needs to be shut off to clean the nozzles. Consequently, with the design, someone has to claw inside the tight tower space to inspect or clean the nozzles.

  • ''A Plus Quality Inc/Heating and Cooling Services'' bailed me out of a difficult situation. My furnace quit with -18C° temperatures at 8pm on a Saturday. We had an infant at home and the house was cooling dramatically. By 10pm one of their technicians, Jack arrived and was able to show me how dangerous my situation really was. By 10am Sunday morning another technician, Dave began the installation of a new furnace. Shortly after, Jack joined in. Each gentleman was friendly, informative and answered all subsequent questions. Thank you for going above and beyond. Would highly recommend both technicians and the company they represent.

  • Today I had an unfortunate issue with my furnace resulting in a full replacement. At this point I was worried I would be without heat in the beginning of winter and started to prepare myself for the worse case scenario. I decided to call A Plus Quality Inc who I have been dealing with for a while in hopes that they would be able to bail me out of this jam, and that's exactly what they did. Within 5 hours they had 2 men at my home disassembling my old furnace and replacing it with a new one. I would've never thought I could've had this issue resolved in 1 day, let alone hours. The level of professionalism and customer service I received today was far more than I could've ever imagined. I have nothing but good things to say and would definitely recommend this company to anyone. Thanks again for all your help.

  • Called about getting a cleaning for my furnace and AC in the morning. Booked a time within the hour and they were at my house within the next day. Very reasonable in pricing comparative to other companies. They provided exceptional work and very happy with how thorough they were. Honestly would 100% recommend and loved your service and will definitely use again for any further needs.

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • 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”.

  • 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

  • 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
  • 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.
