When it comes to installing a new furnace, whether it’s a gas, electric, or oil furnace, one crucial step is often overlooked or underestimated: the furnace installation inspection. This inspection is vital to ensuring that your furnace is installed correctly, up to code, and safe to operate. In this article, we will discuss the necessity of a furnace installation inspection, what it entails, and the specific requirements for different types of furnaces.
The Necessity Of A Furnace Installation Inspection
A furnace installation inspection is a mandatory step that ensures your new heating system is installed correctly and meets all the necessary safety and building code requirements. Regardless of the type or brand of furnace you install, obtaining a permit for the inspection is not just recommended; it’s required by law. The purpose of this inspection is to safeguard your home and family by confirming that the furnace is safe and in compliance with the manufacturer’s guidelines and local regulations.
What Does A Furnace Installation Inspection Entail?
In general, a furnace installation inspection involves a comprehensive evaluation of the installation to ensure it adheres to the manufacturer’s specifications and local building codes. The inspector will also verify if the electrical connections meet the current code requirements and examine the plenum and connections to existing ductwork. However, specific inspection requirements can vary depending on the type of furnace being installed.
Gas Furnace Inspections
Gas furnaces are subject to some of the strictest inspection requirements due to the potential hazards associated with gas leaks or explosions. When inspecting a gas furnace installation, the following aspects are typically assessed:
- Furnace and Its Location: The type of heating method and energy source used by the furnace is noted, along with its location, ensuring accessibility and safety.
- Thermostat: The inspector checks the thermostat’s functionality and documents its location.
- Ventilation: Exterior surfaces of the vent exhaust system are examined for signs of condensation, corrosion, damage, cracks, or blockages. Vent connector pipes, outlet and inlet exhaust pipes and connections, pipe fastening, insulation around plastic vent pipes, and clearance between vent connector pipes and combustible materials are inspected.
- Gas Line Hookup: The location of the shut-off valve, sediment trap, union installation, and the solidity of gas pipes are examined. The gas valve assembly is tested for functionality.
- Disconnect/Emergency Switch: The presence and condition of this switch are checked, along with its location and safety.
Other components that undergo inspection include the furnace cabinet, service shut-off switch, blower door switch/control board, inducer motor, burners and manifold, igniter and flame, pressure switches, limit switches, condensate trap and drainpipe, light and electrical receptacle, and the protective barrier.
Electric Furnace Inspections
Electric furnaces, lacking gas or oil lines, have fewer inspection requirements. However, they still require an inspection to ensure safety and compliance. During an electric furnace inspection, the focus is primarily on the installation and electrical connections, which must be secure and properly configured. The panel boxes, disconnects, and circuit breakers are thoroughly examined for performance issues such as shorts, overheating, corrosion, or improper installation.
Oil Furnace Inspections
While gas and electric furnaces are more common, some homeowners opt for oil-burning boilers and forced-air systems. Building codes necessitate the inspection of the oil tank and oil line connections, as well as an examination of flue lines and intakes to verify proper operation. For boilers with closed loops, the inspection ensures secure connections and no leaks.
The Cost Of A Furnace Installation Inspection
The cost of a furnace installation inspection typically ranges from $75 to $200, depending on your location. It’s worth noting that this cost is typically included in the price of obtaining a permit for the installation. However, it’s essential to be aware that if the inspector identifies the need for additional work, such as an updated electrical panel, new gas lines, ductwork adjustments, or exhaust flue modifications, these secondary repairs and updates can significantly increase the overall cost of your furnace installation project.
A furnace installation inspection is a critical step in ensuring the safety and efficiency of your heating system. Regardless of the type of furnace you choose, adhering to the inspection requirements is essential to prevent potential hazards and ensure that your furnace complies with local regulations and building codes. By investing in a thorough furnace installation inspection, you can enjoy the peace of mind that your home will be comfortably and safely heated during the cold months.
