Hamilton Heating and Cooling supplies professional affordable air conditioning installation in Hamilton.  We deal with the industry leading brand names that you know and trust. Our technicians are trained to get you the proper high efficiency air conditioner that fits your home or office.

Here’s a few things we consider when we are outfitting you with the right unit.

The size of any air-conditioning unit is expressed in British Thermal Units (BTU). The higher the number, the more cooling capacity. An approximate guide is 20 BTU for every square foot of space you need cooled. Keep in mind there are many other factors that go into making a final decision.

Our air conditioning installation in Hamilton team can help. We want our customers to avoid the issues they can otherwise have with an incorrectly sized air-conditioner. Remember one that’s too small is just as big an issue as one that’s too big.

  • An undersized ac won’t have enough power to cool your entire house. That’s even if the air-conditioner runs continuously.
  • If the appliance is too large, you’ll have other issues. One of these will cycle on and off too quickly without cooling your house properly and thoroughly. An oversized unit won’t be able to dehumidify the house properly either.
  • An undersized air conditioner will run continuously. That spells excessive wear and tear and higher repair bills. If it’s oversized, the appliance short cycles and that causes the same type of repair issues.


Getting expert advice will help you to find the right size air-conditioner. The following factors need to be considered.

  • The Climate. Finding an air-conditioner that can cope with high humidity levels is important for homes in southern Ontario.
  • The Insulation and Duct Work. It’s important to make sure that both of these are adequate. Checking both of these boxes off means that you can get ahead on energy savings.
  • The Layout and Size of Your Property. Any assessment will take into account the square footage of your home and a number of stories.
