Is It Time To Replace Or Repair Your Central AC Unit?
If you already own a central air conditioner, you may be wondering whether to replace the system or whether you can get away with just repairing your AC.
Your air conditioning might be worth fixing if it is relatively new and the repair is minor. However, now is the time for replacement when your AC:
- Runs up huge energy bills because its efficiency is declining
- Needs frequent, costly repair
- Uses R-22 refrigerant, which the Canadian government is phasing out due to its ozone-depleting effect
- The lifespan of an air conditioner is 10 to 15 years old (learn about how you can determine the age of your AC)
If cost is a concern, we offer HVAC system financing options to make replacing your air conditioner manageable for your budget.
Benefits Of Installing A Central AC
Are you currently trying to beat the heat with window air conditioners or fans? Those are really only makeshift solutions, which don’t offer the great benefits of a central air conditioning installation, like:
More Convenience
Central AC units will not block your light or your view, take up much-needed floor space or direct its cooled air only to one small area of a room. Instead, it works to cool your entire house or building comfortably, quietly, and conveniently.
Better Air Quality
Do you want cleaner, less humid indoor air? Central air conditioners filter dust, animal dander, pollen, and other irritants out of the air circulating through your ductwork. They also provide a dehumidifying feature. The result is improved air quality and health benefits to the occupants of your home or business.
Higher Home Value
If you’re selling a house, you should know that today’s buyers tend to want move-in-ready homes, complete with good quality, efficient HVAC systems. In addition, central air conditioning units add home value and curb appeal.
Types Of Central Air Conditioners
There are 2 basic types of central air conditioners, split and packaged systems.
Split
A split central air conditioner is so-called because it is “split” into two main parts:
1. the evaporator coil, which is located in a cabinet indoors, which frequently includes a furnace or air handler as well
2. the condenser and compressor, enclosed in a weather-resistant metal cabinet outdoors
This type of AC unit distributes cooled air through your home using the same ducts that circulate warm air from your furnace in winter. It is the most popular kind and the most economical to install in large premises already fitted with existing ductwork.
Package
With packaged air conditioning units, the evaporator, compressor, and condenser are all to be found in a single cabinet, which may also contain a gas furnace or electric heating coils. The cabinet is usually installed outdoors, on the home’s roof, or a concrete slab at the foundation level.
Packaged AC is great for small buildings since it is a space saver. It’s also simpler to install.

Napoleon
Napoleon air conditioners have gained immense popularity as a top-notch brand of cooling systems. They’re renowned for their efficiency, reliability, and cutting-edge features. The primary aim of Napoleon air conditioners is to deliver ultimate comfort while keeping energy usage in check.
Energy Efficiency
Look at the SEER (Seasonal Energy Efficiency Ratio) rating for a highly efficient central air conditioner. The higher this is, the better. A heat pump vs. an AC is a good alternative if you’re looking for an energy-efficient cooling system. Federal standards in 2025 mandate a SEER of at least 13 for new air conditioners. While a 14.5 SEER rating will earn Energy Star certification, some AC units are rated 25 or higher.
Multi-Zone Cooling & Heating
Take control of your home comfort — at the time of your central air conditioning installation, you can have your HVAC technician set up multi-zone cooling and heating. They will insert a system of dampers in your ductwork. This divides your house into several smaller zones, each with its own thermostat to fine-tune the temperature.
Size The Central AC Correctly
Buying the right size central air conditioning system should never be a matter of guesswork because an incorrectly sized system will leave you a lot less comfortable than you hoped. An undersized AC won’t be able to get your whole space cool enough. At the same time, an oversized one will end up short-cycling, failing to properly dehumidify, and eventually wearing out much sooner than normal.
The required size air conditioner is measured in terms of BTU (British Thermal Units). As a rough estimate, you will need 20 BTU of cooling power per square foot, but an accurate calculation will have to take into account several other essential factors, including:
- Number of stories in the residence
- Ceiling height(s)
- Amount of sun exposure
- Number and position of windows and exterior doors
- Even the usual number of occupants! (More people = more body heat, making a larger AC necessary.)
Maintain Your Central Air Conditioner Yearly
You’re investing a good chunk of hard-earned cash into your new air conditioner. Make the most of your investment by keeping the system in excellent running order. Yearly professional air conditioner maintenance should include thorough inspection, cleaning, and repair of any small issues.
