Central Air Conditioners - Cool Comfort a Call Away
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.
Choosing or Upgrading Your Central Air Conditioner
To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioners energy use. 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 sulfur dioxide.
If you have an older central air conditioner, you would do well to replace it with a high-efficiency unit. Considering recent changes in refrigerants and air conditioning designs, it is imperative that you replace the entire system.
Today's best air conditioners use 30%–50% less energy to produce the same amount of cooling as air conditioners made in the mid 1970s. Even if your central air conditioner is only 10 years old, you may save 20%–40% of your cooling energy costs by replacing it with a newer, more efficient model.
When buying a central air conditioner, 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 central air conditioners with SEER ratings of 13 or greater, but consider using air conditioning equipment with higher SEER ratings for greater savings.
Other Features to Look For When Buying an Air Conditioner:
- 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

To repair or replace, that is the question that likely comes to mind whenever your heating or Air Conditioning system stops working like it should. Although repairing may be the most affordable solution now, it might not be the best choice over the long run.
Factors to consider include:
Fifty Percent Rule
When the cost of HVAC repairs approaches 50% of the value of your heating or cooling system, it’s generally time to replace the system.
Other Rules of Thumb
Even if needed HVAC repair costs aren't quite as daunting as 50%, you might want to replace your system if it’s more than 12 years old or you’ve had a history of problems with it. Also, it might be worthwhile to take advantage of one of several opportunities:
- Convenience – When you purchase a new HVAC system, you can avoid the hassle of unexpected repairs down the line, and you don’t have to sit around uncomfortable while waiting for parts.
- Lower utility bills – A high-efficiency home Heating and Air Conditioners system from Lennox can save you hundreds of dollars each year in energy costs, compared to an older system.
- Energy tax credits – You can recover up to 30% of the cost of select high-efficiency systems in the form of tax credits.
- Friendlier refrigerant – Due to growing environmental concerns, the U.S. federal government has mandated that all HVAC manufacturers phase R-22 refrigerant-based equipment out of production. In response, Lennox now mainly manufactures cooling systems with R-410A, a U.S. EPA-approved, chlorine-free refrigerant.
- Enhanced comfort – Advanced technologies that improve energy efficiency also enhance your comfort, so you can enjoy more even temperatures, better humidity control and a constant flow of conditioned air.
- Improved air quality – Better humidity control means a reduced potential for mold and mildew growth. Lennox home comfort systems are also available with Healthy Climate® filtration, which minimizes the impact of indoor pollutants.
Matching is usually a term that relates to colors, but it’s also important when talking about Heating and Air Conditioning systems. By combining Lennox® products that are made to work together, you can create an ideal system for your home.
A perfect match = peak performance
While an outdoor air conditioning system may "work" with indoor units, including older systems, it will only operate at its peak potential when it’s paired with the right sized system for your home. in addition, and possibly more important, the old coil may fail long before the expected life span of the exterior condenser, causing added expense and potential damage to the newer unit.
