Our answer is, it’s a smart approach. Here's why.
Paired design—Your furnace. This can help better energy efficiency and performance.
Technology enhancements—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet operation. You’ll get these benefits year-round when you improve the complete system.
Improved heating and cooling efficiency—Efficiency rankings are determined on corresponding system performance. While putting in one new unit will result in better performance, efficiency will be lower from what it was designed to be. And your savings will not be as large as they’d be with matching units.
Equipment age—If your AC is 10 years old (or older), your heater is likely just as outdated. Replacing both means you’ll enjoy lots of years of efficient comfort, regardless of the season.
New warranty—A new set of equipment also means you’ll get new system warranties. You’ll have peace of mind when you realize the warranty covers your complete system for the same period of time.
It would appear replacing only your AC or furnace could appear to be a smart decision. But it’s not a great bargain when you factor in reduced efficiency.
Getting an entirely new system might be more expensive, but you receive much more efficiency, reliability and comfort for many years in Canada.
