Energy Efficiency and Maryland Climate Considerations
Choosing ENERGY STAR® certified systems significantly lowers energy usage and utility costs in Maryland’s climate. Since summers can be hot and humid while winters bring freezing temperatures, HVAC systems must be robust and properly sized. Pro tip: Scheduling seasonal maintenance extends equipment lifespan and maintains safe indoor air quality, especially in neighborhoods near Chesapeake Bay where humidity fluctuates.
Understanding HVAC Permits and Local Codes in Maryland

Maintaining Your HVAC System in Maryland
Regular HVAC maintenance is crucial in Maryland’s climate to avoid common issues like mold growth, refrigerant leaks, or compressor failures. Ideally, schedule spring tune-ups before the summer heat and fall inspections before heating season.
