What is a Furnace Inspection and How to Do That

Table of Contents

Your furnace is the backbone of your home’s heating system, ensuring that you and your family stay warm during the colder months. However, like any complex piece of equipment, your furnace needs regular inspections and maintenance to keep running efficiently and safely. Furnace inspections help prevent unexpected breakdowns, reduce energy bills, and extend the life of your heating system.

At BCRC Heating and Cooling, we understand the importance of furnace inspections. In this comprehensive guide, we will explain what a furnace inspection involves, why it’s essential, and how to properly conduct one to ensure your system operates at its best.

What is a Furnace Inspection?

A furnace inspection is a detailed examination of your furnace and its components to ensure everything is working efficiently and safely. It typically involves a licensed HVAC technician who checks for signs of wear and tear, potential malfunctions, and ensures your system meets safety standards.

Regular furnace inspections help homeowners identify and fix small issues before they become costly repairs or lead to dangerous situations like carbon monoxide leaks. It’s generally recommended to have your furnace inspected at least once a year, ideally before the winter season.

Why is a Furnace Inspection Important?

Here are some key reasons why you should schedule regular furnace inspections:

  1. Safety: Furnaces burn fuel to produce heat, which can lead to carbon monoxide (CO) leaks if not properly maintained. An inspection will identify any potential safety risks, including faulty burners or cracked heat exchangers, that could lead to dangerous situations.

  2. Efficiency: Regular inspections help maintain your furnace’s efficiency. When components are clean and in good working order, your system uses less energy, reducing your heating bills.

  3. Prevent Breakdowns: Small problems can quickly escalate into major issues if not caught early. A furnace inspection can prevent unexpected breakdowns during the colder months when you need your heating system the most.

  4. Extended Lifespan: Routine inspections can extend the life of your furnace. Proper maintenance reduces wear and tear, allowing the system to run efficiently for longer.

  5. Warranty Compliance: Many furnace manufacturers require regular inspections and maintenance to keep warranties valid. Failing to have your furnace inspected could void your warranty and leave you paying out-of-pocket for repairs.

What Does a Furnace Inspection Include?

A professional furnace inspection typically covers the following components:

Thermostat Check

Your HVAC technician will check that the thermostat is properly calibrated and functioning correctly. A faulty thermostat can cause your furnace to cycle too often or not run when needed, affecting both comfort and efficiency.

Inspecting the Air Filter

Air filters trap dust and debris, preventing them from circulating through your home’s air and clogging your furnace. During the inspection, the technician will either clean or replace the air filter to ensure proper airflow and indoor air quality.

Examining the Blower Motor

The blower motor powers the fan that circulates warm air throughout your home. An inspection involves checking the motor for any wear and tear and ensuring it is lubricated and running smoothly.

Checking the Heat Exchanger

The heat exchanger is one of the most important parts of your furnace. It heats the air that is distributed throughout your home. If the heat exchanger is cracked or damaged, it could leak dangerous carbon monoxide gas. During the inspection, the technician will carefully examine it for any cracks or corrosion.

Cleaning the Burners

Dirty burners can cause improper combustion, reducing your furnace’s efficiency and potentially releasing harmful gases. A furnace inspection includes cleaning the burners to ensure they are burning fuel correctly and efficiently.

Inspecting the Flame Sensor

The flame sensor detects whether the furnace is properly igniting and burning fuel. If the flame sensor is dirty or faulty, the furnace may shut down to prevent unsafe combustion. A technician will clean and test the flame sensor during an inspection.

Inspecting the Ventilation System

Proper ventilation is crucial to safely expel exhaust gases from your home. The HVAC technician will check the flue and ventilation pipes for blockages, leaks, or signs of damage to ensure proper airflow and safety.

Examining Electrical Connections

Loose or damaged electrical connections can cause your furnace to malfunction or stop working altogether. During an inspection, the technician will check all wiring and electrical components for damage and tighten any loose connections.

Testing the Safety Controls

Your furnace is equipped with various safety controls to protect your home from fire hazards or carbon monoxide poisoning. A furnace inspection involves testing all safety controls to ensure they are functioning correctly.

Inspecting the Gas Line and Pressure

If you have a gas furnace, the technician will check the gas line and pressure to ensure there are no leaks or issues that could affect your system’s performance or safety.

Inspecting the Pilot Light or Ignition System

Older furnaces have a pilot light, while newer models use electronic ignition systems. Both systems are responsible for igniting the furnace. During an inspection, the technician will check for proper operation and address any issues with ignition.

How to Perform a Basic DIY Furnace Inspection

While it’s always recommended to have a professional furnace inspection annually, there are a few things homeowners can do themselves to keep their furnace running smoothly in between professional visits.

Check and Replace the Air Filter

Your furnace’s air filter should be checked every month, especially during the colder months when your system is running frequently. If the filter is dirty or clogged, replace it with a clean one. A clean air filter improves airflow and reduces strain on your furnace.

Clean the Furnace Exterior

Dust can accumulate on the exterior of your furnace, especially in basements or utility rooms. Clean the furnace’s exterior with a damp cloth to prevent dust from entering the system.

Test the Thermostat

Set your thermostat to heat mode and raise the temperature to ensure the furnace starts up. If there’s a delay or the furnace doesn’t turn on, it may indicate an issue with the thermostat or another component.

Listen for Unusual Noises

Turn on your furnace and listen for any unusual noises like banging, rattling, or squealing. These sounds could indicate loose components or other mechanical issues that need attention.

Inspect the Vents and Registers

Walk through your home and check that all the vents and registers are open and unobstructed. Blocked vents can reduce airflow and cause your furnace to work harder than necessary.
