If you’re thinking of replacing some or all of your central air conditioner or heat pump, you may hear the HVAC pro talk about the importance of a properly matched system. The term refers to the compatibility of the indoor component, the air handler, with the outdoor component, its outdoor condenser.
A/Cs and heat pumps have come a long way over the years and part of their improved performance comes from matching the indoor components to the outdoor equipment. Engineers get the most efficiency, reliability and durability from the systems by precisely tailoring some of the parts to each other.
What Needs to Match
The type of refrigerant and capacity of the evaporator and condenser coils must match in order for the system to run properly. Mixing different kinds of refrigerant will cause major system problems as will using the wrong refrigerant.
The evaporator coil sits inside the air handler and the condenser coils in the outdoor condenser. Both must have a the same capacity for the refrigerant in the system to work. If one is the wrong size, the system won’t work as well, if at all. HVAC repairs and replacements cost a good deal, and investing in upgrades that may fail makes little financial sense.
Determining the Matches
The Air Conditioning, Heating and Refrigeration Institute (AHRI) maintains a database of all central air conditioning and heat pumps and the components that match each system. New equipment comes with an AHRI certifies that assures a properly matched system.
If you’re able to replace just one component, verify that the AHRI certificate indicates that both the air handler and the outdoor condenser match. If they don’t, the manufacturer may not honor the warranty and the installer may not be able to extend any guarantees.
Before moving forward with a full or partial HVAC system replacement, be sure that that the components are a properly matched system. For more information about its importance, contact Mathews CCAC. Inc., providing trusted HVAC services for Coastal Bend homeowners.
