Upgrading Your Central HVAC in Ottawa

Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This is by far the most common method of air conditioning used in Canada.

At Climate Works, we carry the best central air conditioners in Canada and pride ourselves in industry-leading customer service and service after the sale.

Things to Consider When Buying an Ottawa Air Conditioner

If you have an older central air conditioner in Canada, you would do well to replace it with a high-efficiency unit. Considering recent changes in refrigerants and designs of new air conditioners in Ottawa, it is imperative that you replace the entire system.

To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioner’s energy use. The best new air conditioners use 30-50% less energy and produce the same amount of cooling as air conditioners made over 50 years ago.

Older air conditioners may consume more than 2000 kilowatt-hours of electricity per year, causing power plants to emit about 3500 pounds of carbon dioxide and 31 pounds of sulphur dioxide.

So, if you can’t find a central air conditioner sale in Ottawa and need to purchase your central air conditioning system at full price, you’re still going to save money in the long-run because of the energy savings.

When buying a central air conditioner in Canada, look for a model with a high efficiency. Central air conditioners are rated according to their seasonal energy efficiency ratio (SEER).

SEER indicates the relative amount of energy needed to provide a specific cooling output. Many older systems have SEER ratings of 6 or less. The minimum SEER allowed today is 13.

Look for the ENERGY STAR label for air conditioners with SEER ratings of 13 or greater, but consider using central air conditioning equipment with higher SEER ratings for greater savings.

To determine a more precise size, it’s best to have a professional HVAC contractor perform a Manual J load calculation. This takes into account specific factors about your home, such as:

  • Home’s square footage
  • Insulation levels
  • Window types and sizes
  • Number of occupants
  • Appliances and lighting
  • Ductwork condition

Properly sizing the AC unit is crucial for optimal performance, efficiency, and comfort. An oversized unit will cycle on and off too frequently, leading to poor humidity control and increased wear. An undersized unit will struggle to cool your home effectively.

A typical Central Air Conditioner in Ottawa is also known by the more technical term “split-system Air Conditioner”. This type of Air Conditioner consists of separate indoor and outdoor sections. The indoor heat exchanger, or coil, mounts above the furnace inside the ducting. They are also known as Central Heat Pumps.

The outdoor section contains the compressor and the main operational components. The two sections are joined by refrigerant lines which circulate the refrigerant between the indoor coil to the refrigeration components in the outdoor section.

The indoor air conditioning coil is cold, which causes the humidity to condense and be drained away while also cooling the air.

  • A thermal expansion valve and a high-temperature rating (EER) greater than 11.6, for high-efficiency operation when the weather is at its hottest.
  • A variable speed Gas Furnace or Air Handler can dramatically improve performance. Consider changing it as a system
  • A unit that operates quietly
  • A fan-only switch, so you can use continuous fan operation
  • A Furnace Filter check light to remind you to check the filter after a predetermined number of operating hours

Choose new air conditioners in Ottawa to enjoy clean air at cool temperatures during the hotter months without incurring exorbitant energy costs. However selecting the right air conditioning solution for your needs can be a complex and time-consuming task, given the plethora of options available in the market.

Several factors worth considering are Seasonal Energy Efficiency Ratio (SEER), price, warranty, and added features or functionality. However the exact cost will be determined by the air conditioning system’s size and output, home size, and the type and condition of existing insulation and ductwork.
