Q. Will cleaning the outside coil in below freezing condition cause ice up problems?
A. In severe cold conditions we blow dry the outside coil. Any remaining moisture will be cleared by the normal defrost mode which is automatic on the outside coil. As you know in Nova Scotia we often go from a rain / fog condition to freezing within hours. That is why the automatic defrost mode is part of your system. Basically in the defrost mode the inverter will periodically go from heat mode to air conditioning mode. This causes the outside condenser to become warm and defrosts the moisture from the coil. At Breathe Clean we have never had a problem with the outside unit freezing up after service call.
After we remove your mini split cover, if you don't agree it requires a deep clean, Breathe Clean will reinstall the cover and leave with no charge.
