• The Furnace/Air Handler: This unit is responsible for heating the air in the winter and circulating it throughout your home. It typically contains a burner, heat exchanger, blower motor, and air filters. In air conditioning systems, the air handler also houses the evaporator coil.
• The Air Conditioner/Heat Pump: This unit is responsible for cooling the air in the summer. It contains a compressor, condenser coil, and expansion valve. Heat pumps can also provide heating in milder climates.
• The Ductwork: This network of ducts distributes conditioned air throughout your home. Ducts can be made of metal, fiberglass, or flexible materials.

These components work together to regulate the temperature, humidity, and air quality within your living space. Regular maintenance and timely repairs are vital for the efficient operation of each part and the system as a whole. 24 Hour Emergency Heating Service Residential Ac Repair 24 7 Hvac Near Me Heating And Air Conditioning Service Near Me Air Conditioner Repair Man
