What is a Furnace?

A furnace is a device used for heating purposes. It’s typically used to generate heat for a building or to perform industrial processes. Furnaces can be fueled by various energy sources such as natural gas, oil, electricity, or wood. They work by heating air, water, or other fluids and distributing the resulting heat throughout a space via ductwork, radiators, or other means.

In residential settings, furnaces are often part of a central heating system, where they heat air which is then circulated throughout the house via ducts and vents. In industrial applications, furnaces are used for processes such as melting metals, drying materials, or producing steam for power generation.

Types of Furnaces

Gas Furnaces

These are the most common type of residential furnaces. They use natural gas or propane as fuel and operate by burning the gas in a combustion chamber. The heat generated is then transferred to the air, which is distributed throughout the building via ductwork.

Electric Furnaces

Electric furnaces use electric resistance heating elements to generate heat. When electricity flows through these elements, they produce heat, which is then circulated through the building using a blower fan. Electric furnaces are often used in areas where electricity is more readily available or where other fuel sources are impractical.

Multi-Fuel Furnaces

Some furnaces are designed to burn multiple types of fuel, such as wood pellets, coal, or biomass. These versatile furnaces offer flexibility in fuel choice and can be more resilient to fluctuations in fuel availability or cost.

Modulating Furnaces

Modulating furnaces are equipped with variable-speed blowers and gas valves, allowing them to adjust heat output based on real-time heating demands. This results in more precise temperature control and improved energy efficiency.

Oil Furnaces

Oil furnaces use heating oil as their fuel source. They operate similarly to gas furnaces, with oil being burned in a combustion chamber to generate heat. Oil furnaces are less common than gas furnaces but are still used in areas where natural gas is not readily available.

Wood-Burning Furnaces

These furnaces burn wood as fuel to generate heat. They can be used in residential or industrial settings and are often used in rural areas where wood is abundant. Wood-burning furnaces require regular fueling and maintenance but can be a cost-effective heating option.

High-Efficiency Furnaces

High-efficiency furnaces are designed to maximize heat output while minimizing energy waste. They often incorporate advanced features such as condensing technology, which allows them to extract more heat from combustion gases, resulting in lower fuel consumption and reduced energy costs.

Furnace Inspections

A furnace inspection is crucial for maintaining the safety, efficiency, and longevity of your heating system. It allows you to identify and address any issues before they escalate into more significant problems, ensuring reliable performance and peace of mind. It’s recommended to schedule regular furnace inspections, ideally before the start of the heating season, to ensure your furnace is in top condition when you need it most.

Visual Inspection

The technician will visually inspect the furnace, looking for any signs of damage, corrosion, or wear. They will check the exterior components as well as internal parts visible without disassembly.

Inspecting Electrical Components

Our technician will inspect electrical connections, wiring, and terminals for signs of damage or wear. They will check for loose connections and ensure that all electrical components are in good condition.

Checking Airflow

Proper airflow is essential for efficient furnace operation. Our technician may check the airflow through the furnace and ductwork to ensure it is unobstructed. They may also inspect ducts and vents for any blockages or leaks.

Safety Checks

Safety is a primary concern during a furnace inspection. The technician will check for gas leaks, carbon monoxide leaks, and proper ventilation to ensure safe operation. They will also inspect the ignition system, burner assembly, and heat exchanger for any issues that could pose safety risks.


The technician may clean various components of the furnace, including the burners, blower fan, heat exchanger, and air filters. Accumulated dirt, dust, and debris can hinder the furnace’s efficiency and potentially lead to malfunctions.


The technician will test the operation of the furnace by starting it up and monitoring its performance. They will check for proper ignition, burner operation, and heat output. They may also test the thermostat and other controls to ensure they are functioning correctly.

Inspecting Flue and Venting

Our technician will inspect the flue and venting system to ensure proper exhaust ventilation. They will check for any obstructions or leaks that could impact the furnace’s performance or pose safety risks.


Based on our team’s inspection findings, the technician may provide recommendations for any necessary repairs, replacements, or maintenance tasks. They may also offer advice on furnace care and maintenance to keep your system running smoothly.


Our technician will provide you with a written report detailing the results of the inspection, any findings or recommendations, and the overall condition of your furnace.
