What is a Furnace Inspection and How to Do That

Table of Contents

Your furnace is the backbone of your home’s heating system keeping you and your family warm during the colder months. Like any complex piece of machinery, your furnace requires periodic inspections and maintenance to ensure it’s running safely and effectively. Furnace inspections prevent unexpected breakdowns, reduce energy bills, and extend the life of your heating system.

At BCRC Heating and Cooling, we know how important furnace inspections are. In this ultimate guide, we’ll walk you through what a furnace inspection is, why it’s important, and how you can properly inspect your furnace to keep your system running its best.

What’s a Furnace Inspection?

A furnace inspection involves a thorough inspection of your furnace and all associated components to make sure everything is functioning properly and safely. A licensed HVAC technician will usually inspect for wear and tear, possible breakdowns, and confirm your system is up to safety standards.

Routine furnace inspections allow homeowners to catch and correct minor problems before they become expensive repairs or dangerous situations such as carbon monoxide leaks. It’s usually recommended to have your furnace checked at least once a year, preferably before the winter season.

Why do you need a furnace inspection?

Some of the main reasons to have your furnace inspected regularly include:

  1. Safety: Furnaces burn fuel to generate heat, which can cause carbon monoxide (CO) leaks if not maintained properly. The inspection will identify any safety hazards, such as broken burners or cracked heat exchangers, that could potentially create hazardous conditions.

  2. Efficiency. Routine inspections of your furnace help it to operate efficiently. Your system will use less energy, lowering your heating bills, when components are clean and in good working order.

  3. Prevent Breakdowns: Small problems can become big problems if left unchecked. The best way to avoid surprises when you need your heating system the most, during the colder months is to get a furnace inspection.

  4. Longer Life: Regular inspections can lengthen the life of your furnace. Proper maintenance will keep the system running efficiently for longer and will reduce wear and tear.

  5. Warranty Compliance: Numerous furnace manufacturers mandate routine inspections and maintenance to maintain warranty validity. Not having your furnace inspected could void your warranty and leave you paying out-of-pocket for repairs.

What’s Included in a Furnace Inspection?

It’s common for a professional furnace inspection to include:

Checking the Thermostat

Your HVAC technician will also check the thermostat to make sure it is calibrated and operating correctly. If your thermostat is broken, your furnace may run too often or not at all when it should. This can impact your comfort and efficiency.

Check the Air Filter

Air filters catch dust and debris before they can circulate through the air in your home and clog your furnace. The technician will also clean or replace the air filter during the inspection so that proper airflow and indoor air quality are maintained.

Blower motor inspection

The blower motor is what powers the fan that circulates warm air throughout your home. “An inspection is looking at the motor and seeing if it’s worn out and making sure it’s oiled and functioning right.

Checking the Heat Exchanger

The heat exchanger is one of the most important components of your furnace. It then heats the air , which is blown all over your house . If the heat exchanger is cracked or damaged it could leak dangerous carbon monoxide gas. During the inspection, the technician will check for any cracks or corrosion.

Cleaning the Burners

Dirty burners can cause improper combustion which reduces your furnace efficiency and can release harmful gases. During a furnace inspection the burners are cleaned so they are burning the fuel correctly and efficiently.

How to Test the Flame Sensor

The flame sensor checks to see if the furnace is lighting properly and burning fuel. A dirty or defective flame sensor can cause the furnace to shut off to prevent unsafe combustion. During an inspection, a technician will test and clean the flame sensor.

Ventilation System Inspection

The key is proper ventilation to vent exhaust gases out of your home. The HVAC technician will inspect the flue and ventilation pipes for blockages, leaks, or damage to ensure proper airflow and safety.

Testing Electrical Connections

Loose or damaged electrical connections can make your furnace malfunction or stop working altogether. The technician will inspect all wiring and electrical components for damage and tighten loose connections.

Testing of Safety Measures

Your furnace has a number of safety controls to keep your home safe from fire hazards or carbon-monoxide poisoning. A furnace inspection involves testing all safety controls to ensure they are functioning properly.

Checking gas line and pressure

If you have a gas furnace, the technician will check the gas line and pressure to make sure there are no leaks or problems that could affect the safety or performance of your system.

Look at the Pilot Light or Ignition System

Older furnaces have a pilot light, newer ones use electronic ignition systems. The two systems are responsible for lighting the furnace. When we inspect it, we’ll make sure everything is working properly and we’ll fix any ignition problems.

How to Do a Basic DIY Furnace Inspection

While it’s always best to have a professional furnace inspection each year, there are a few things homeowners can do on their own to keep their furnace running smoothly in between professional visits.

Change and Check the Air Filter

Check the air filter of your furnace every month, especially during the colder months when your system is working hard. Replace a dirty or clogged filter with a clean filter. A clean air filter helps improve airflow and reduces the stress on your furnace.

Furnace Outside Cleaning

Dust could settle on the outside of your furnace, particularly in basements or utility rooms. Use a damp cloth to wipe the outside of the furnace to keep dust out of the system.

Test the Thermostat

Turn your thermostat to heat and crank the temperature up to start your furnace. If the furnace is slow to respond or doesn’t come on at all, the thermostat or another part could be the problem.

Listen for Weird 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.
