Our reply is, it’s a good method. Here's why.
Matched design—Your furnace is designed to function with a matching air conditioner. This might help enhance energy efficiency and performance.
Technology upgrades—There have been abundant recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll have these perks year-round when you improve the whole system.
Improved heating and cooling efficiency—Efficiency ratings are formed on matched system performance. While installing one new unit will improve 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 a matched system.
Equipment age—If your AC is 10 years old (or older), your heater is likely just as outdated. Replacing both means you’ll receive many years of efficient comfort, regardless of the weather.
Updated warranty—A new set of equipment also means you’ll get new system warranties. You’ll receive peace of mind knowing the warranty covers your entire system for the same time period.
It would appear getting only a new cooling system or heating system can feel like a smart decision. But it’s not a great decision when you include lower efficiency.
Getting an entirely new system may be costlier, but you earn much higher efficiency, reliability and comfort for many years in Toronto.
