When it comes to higher-efficiency unitary products, is coil matching as critical as it has been in the past? The answer is an unqualified yes!
When it comes to coil matching, don't cut corners. If a replacement air conditioner or heat pump needs to be installed, it's as important as ever to make sure the indoor coil and outdoor coil are matched. You can't leave the old indoor coil and install a new outdoor unit; performance and longevity will suffer.
