Common signs include uneven heating or cooling, strange noises, higher energy bills, or poor airflow. If your system isn't keeping your home comfortable, it may need professional attention.

Regular maintenance, including changing filters, cleaning ducts, and scheduling annual inspections, can significantly prolong the life of your heating and cooling system while ensuring efficiency.

Energy-efficient systems like heat pumps, smart thermostats, and ENERGY STAR-rated units can reduce energy consumption. A professional consultation can help determine the best system based on your home's needs and climate.
