Baltimore sits at the intersection of humid subtropical and humid continental climate zones, which creates a hostile environment for heat pumps. Winter temperatures swing from 45 degrees during the day to 18 degrees at night. Heat pumps lose efficiency rapidly below 25 degrees, forcing the defrost cycle to run every 30 to 90 minutes. Each defrost cycle temporarily reverses the system, melting ice off the outdoor coil. This constant cycling stresses the reversing valve and runs up your electric bill. Add in the Chesapeake Bay humidity, and you get accelerated corrosion on condenser coils and electrical terminals. The same humidity that makes Baltimore summers muggy also clogs drain lines and promotes algae growth in the condensate pan. These conditions explain why heat pumps in Baltimore fail more frequently than in drier or more temperate climates. Emergency heat pump service calls spike in January and February because this is when aging components finally give out under the stress of repeated freeze-thaw cycles.
