A heat coil HVAC is a type of heating system that is used to provide warm air to a home or building. It works by taking in cold air from outside and passing it through a series of coils that are heated by a furnace or boiler. The heated air is then distributed throughout the building or home. Heat coils are typically used in conjunction with a central air conditioning system to provide both heating and cooling. Heat coils are a great option for those who want to save money on their energy bills, as they are more efficient than traditional heating systems. They also provide a more even temperature throughout the home or building, as the air is heated before it is distributed. Heat coils are also relatively easy to install and maintain, making them a great choice for many homeowners.
