matching hvac unitsGiven the long cooling season in the Houston area, it’s crucial to have the most efficient system your budget can afford. When you buy matching indoor and outdoor units in lieu of simply replacing one part of your system, you’ll get all the benefits an entirely new system gives you.

Sometimes homeowners are tempted to replace just one component of their split system cooling system if there are no apparent problems with one particular side. Doing so may be possible, but over the longer term, it could have comfort and budgetary implications.

Energy Efficiency

One of the most compelling reasons to buy a system whose air handler and outdoor condenser match each other is to be assured of its energy efficiency. The seasonal energy efficiency ratio (SEER) rating indicates how efficiently both components run, but if you only upgrade one unit or the other, you likely won’t achieve the same efficiency the new component promises.


Central cooling systems must be installed by an HVAC contractor who will charge for the installation, whether it’s a complete or partial system. The older portion of an unmatched system may not last as long as the newer component, requiring yet more installation fees.


If you don’t buy matching indoor and outdoor units, you run the risk of losing any warranty the manufacturer offers for the new unit you’re installing. Given the expenses associated with parts and labor, you’re likely better off replacing the entire system for the benefits of a full warranty.

Comfort Issues

Manufacturers have made significant improvements to HVAC systems, and a new system will offer much better noise reduction for the indoor and outdoor units, as well as improved air filtration. Improved air filtration translates to better indoor air quality, which is especially important for anyone suffering from asthma or allergies.
