HVAC and home maintenance: Essential seasonal checks

Homeowners are advised to perform seasonal maintenance on HVAC systems, plumbing, and major appliances to prepare for changing weather. Key tasks include cleaning air filters, checking for leaks, and inspecting windows and doors for drafts.

When transitioning from cooling to heating, a temporary dusty or burning smell may occur as accumulated debris warms up. However, persistent electrical odors, smoke, or unusual noises indicate potential system failure. Common warning signs of HVAC distress include weak airflow, inconsistent temperatures, grinding or banging sounds, and sudden increases in energy bills.

Addressing these issues early can prevent total system failure and reduce the need for emergency repairs, which often involve inspecting refrigerant lines, electrical panels, and compressors.
