For more than four decades, our team at First Class has been the leader among home heating repair companies throughout Maryland and Delaware. We service and install a broad range of makes and models of home-based heating systems, as well as larger commercial installations. We perform heating system repair for the following:

●     Heat Pumps – Distinct from most other heating options, heat pumps move heat from cooler places to warmer ones within the home.

●     Ductless Heating Repairs– Setting up individual coils throughout a building creates independent zones, allowing each thermostat to be set to its own temperature within different rooms.

●     Electric Heating Repairs – These systems can consist of electric heat, electric heaters, or electric water-heating systems.

●     Oil Heaters – These are heaters that operate on radiators fueled by oil.

●     Boilers – A boiler is a closed device capable of heating fluids such as water, natural gas, oil, or propane to fuel another heating system.

●     Water Heaters – Water heaters are used for storing heated water, and they burn energy at a comparatively slow rate.

●     Gas – Gas-based heaters provide heat that is fast, convenient, and easily controlled.

●     Propane – As a byproduct of petroleum and natural gas production, propane burns cleaner than most other fuels and at a more cost-efficient rate.

●     Furnace – The furnace duct system circulates warm air inside the home, while the heat is generated by electricity, oil, or gas.


With manufacturers offering such a wide variety of products, it can be difficult to determine which product will best serve you and your home. Fortunately, First Class can help you find the solution that is right for you.
