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

Our reply is, it’s a good method. Here's why.

Matched design—Your furnace is created to run with a matching air conditioner. This may help improve energy efficiency and performance.

Technology enhancements—There have been a lot of recent advances in HVAC technology, especially in energy efficiency, air filtration and quiet running. You’ll get these perks throughout the year when you improve both units.

Better heating and cooling efficiency—Efficiency ratings are determined on matched equipment performance. While getting one new unit will result in better performance, efficiency will be lacking from what it was engineered to be. And your savings will not be as big as they’d be with matching equipment.

Equipment age—If your AC is 10 years old (or older), your heater is likely just as outdated. Switching both means you’ll receive a lot of of years of efficient comfort, no matter the season.

New warranty—A new set of equipment also means you’ll get valid system warranties. You’ll have peace of mind when you realize the warranty defends your total system for the same time period.

On the surface, installing just a new air conditioner or heating system could feel like a bargain. But it’s not a very good decision when you factor in reduced efficiency.

Getting an entirely new system could be more expensive, but you receive much better efficiency, reliability and comfort for many years in Dallas.
