What we did
A clean evaporator coil is essential for a mini-split to heat and cool efficiently. At this commercial property in Lancaster, we were called in September to service a mini-split air conditioning system.
We performed a thorough cleaning of the evaporator coil. Over time, dust and grime build up on the coil and get in the way of heat transfer, which shows up as weaker temperature differentials between the air going in and the air coming out. Cleaning the coil improves those differentials and helps the system perform the way it should in both heating and cooling. We also ran an emergency test on the condensate pump to confirm it would do its job, then set the thermostat to maintain the desired climate.
The condensate pump is easy to overlook, but it is what carries water away from the indoor unit. If it fails, that water has nowhere to go. Testing it alongside the coil cleaning covers both the performance side and the moisture side of the system. In Kentucky, where humid summers put mini-splits to work removing moisture from the air, keeping the coil clean and the condensate pump working is basic care that helps a business stay comfortable.
