When substituting the outdoor system, should the indoor unit also be replaced?

Our response is, it’s a great approach. Here's why.

Paired design—Your furnace is designed to run with a paired air conditioner. This may help enhance energy efficiency and performance.

Technology advancements—There have been many recent increases in HVAC technology, especially in energy efficiency, air filtration and quiet heating and cooling. You’ll get these advantages all year when you improve the complete system.

Better heating and cooling efficiency—Efficiency ratings are formed on matched equipment performance. While installing one new unit will enhance performance, efficiency will be decreased from what it was engineered to be. And your savings will not be as much as they’d be with matching units.

Equipment age—If your cooling system is 10 years old (or older), your furnace is likely just as dated. Replacing both means you’ll enjoy many years of efficient comfort, whatever the season.

Updated warranty—A new set of units also means you’ll have updated equipment warranties. You’ll receive peace of mind when you realize the warranty defends your whole system for the same period of time.

At first glance, replacing only your air conditioner or heater could seem like a good decision. But it’s not a very good bargain when you factor in reduced efficiency.

Getting an entirely new system might be more expensive, but you receive much higher efficiency, reliability and comfort for long into the future in Oakville.
