What Size Air Conditioner Do I Need?

An image of air conditioners of different sizes

Cooling your home with the right HVAC system helps you maintain a pleasant indoor climate while also adhering to the Canada Greener Homes Grant in some cases. Professional installation is a must, but you should figure out one thing before you arrange for that. You need to have some idea what size air conditioner you need.

How Air Conditioner Sizes Are Determined?

To determine the size of the air conditioning system you need, just multiply the width times the length of the room or home that will get cooled. Then, multiply that number by 25 BTU. This should generate enough cooling, regardless of conditions, ranging from hot, humid summer days to moist and rainy days. If you're only cooling one room that is 12 feet wide and 15 feet long, the two numbers multiply to 180. Multiplying that by 25 BTU for each square foot puts your minimum at 4500 BTU overall.

Things To Consider for Your Air Conditioner

Just buying a new air conditioner is a big investment, but it's not the only cost involved. Does your home have ductwork for it? Where will you put it? How much will you pay for the power usage, increase in your homeowner's insurance, and installation of the unit? Add all these up.

Importance of a Proper Size Air Conditioner

An undersized air conditioner will struggle to cool your home properly, meaning it will consume more power than is necessary and break down faster than it should. That will result in more repairs and earlier replacements. Alternatively, an overpowered system won't run long enough when it's on to actually get heat and moisture out of the air, meaning it will start up and run more often, also wearing it down faster than necessary.

If you decide to install an air conditioner in your home in Toronto & GTA, then you're doing something big for your home. Picking the wrong size of unit can seriously impact the energy cost you have each month. A professional evaluation from A Plus Quality Inc can determine your optimal cooling capacity.

  • ''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.

FAQ

  • 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.

  • 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
     
  • 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”.
