December in Dallas can bring unexpected freezes and icy nights, even if days are mild. HVAC systems, especially heat pumps and furnaces, are at risk during these temperature swings. Frozen outdoor lines, short-cycling, and energy spikes are common problems if systems aren’t prepared.
Tips to Protect Your HVAC in December
Insulate Outdoor Refrigerant Lines:
Cover lines with quality foam insulation to prevent freezing overnight and protect your heat pump.
Check Defrost Cycles:
Ensure your heat pump’s defrost function is operating properly to prevent ice accumulation and system strain.
Seal Drafts Around Windows and Doors:
Cold air infiltration can force your system to work harder. Proper sealing improves efficiency and comfort.
Schedule a Winter Inspection:
A professional check-up can verify refrigerant levels, clean coils, and inspect electrical components for safe, efficient operation.
