Furnace Maintenance Checklist for New Homeowners

Buying a home often means taking over a furnace you know very little about. A furnace maintenance checklist for new homeowners helps you learn about the system in your home and get it ready for Amarillo’s first cold days.

In this guide, we’ll walk you through the checklist for furnace maintenance to do in your first month and what a professional tune-up should cover. Most of the steps only take an afternoon and a flashlight, and give you a clearer picture of the system heating your home.

Quick Answers

• The first 30 days are the best time to learn your furnace’s age and model and find its shutoffs.
• A dust-burning smell is normal on the first startup, while a rotten-egg smell requires immediate evacuation.
• Book a professional tune-up every year, and schedule one soon after you move in if there aren’t any service records.
• Amarillo’s elevation and strong winds can affect how gas burns and clog filters faster than in other areas, so regular tune-ups matter more here.
• Amarillo Air Conditioning offers furnace repairs, installations, and maintenance from NATE-certified technicians who’ve served Panhandle homes since 1955.

Furnace Maintenance Checklist for New Homeowners: Your First 30 Days

The best time to work through the recommended seasonal furnace maintenance checklist below is during the first 30 days. You’ll spot potential problems before you need heat every night and can schedule repairs while they still have room on their calendars.

Find out what furnace you have

The data plate inside the front panel that lists the brand, model, and serial number tells you which furnace you have. Take a photo of it with your phone and save it for future service calls. The serial number usually contains the year it was built, and having it on hand saves time if a technician needs to order parts.

While you have the panel open, take a look at how the furnace vents. A metal flue pipe usually means you have a standard 80% efficiency furnace, while white PVC pipes point to a high-efficiency model.

Ask for service records and warranty paperwork

Ask the sellers or your real estate agent for any furnace service records and warranty documents. Many manufacturers require proof of annual maintenance before they’ll cover parts. Some warranties also don’t transfer to a new owner unless you register the change.

If they don’t have the records, look for a service sticker on the furnace cabinet. Previous companies often write the date of their last visit on it.

Locate the filter, furnace switch, and gas shutoff

Knowing where the filter, furnace switch, and gas shutoff are means you won’t have to search for them when something goes wrong. The filter often sits in a slot between the return duct and the furnace, or behind a large return grille in a wall or ceiling. The size printed on the frame tells you which replacements to buy when it’s time to replace it.

The furnace switch looks like a light switch mounted on the wall or ceiling near the unit. It cuts power to the furnace, which you’ll need before opening any panel.

The gas shutoff is a valve on the gas line leading into the furnace. When the handle runs parallel to the pipe, gas is flowing. Turning it a quarter turn closes it and stops gas from reaching the furnace.

Test carbon monoxide and smoke detectors

Testing carbon monoxide and smoke detectors protects your household in the event of a leak. Press the test button on every alarm to make sure it sounds. You should have a CO alarm on each level of the home and outside sleeping areas. Check the date on the back too, because most CO and smoke alarms need to be replaced every five to 10 years.

Clear the area around the furnace

Clear the area around the furnace so a technician can reach it and nothing flammable is near the burners. Leave about 30 inches open in front of the service panel.

Furnaces often sit in hall closets, garages, or attics, which can quickly fill up during the move-in process. Move any paint, gasoline, cleaning chemicals, or boxes far away to avoid a fire hazard. 

Do a Test Run: What the First Startup Should Smell Like

A test run shows how your furnace performs before the heating season and helps you spot any warning signs it needs repair or complete replacement. When you first turn on your furnace, a burning-dust smell for the first few minutes is normal. Dust settles on the heat exchanger over the summer and burns off once the furnace fires. 

Run the test in early October, before temperatures get too low. If something is wrong, you’ll have time to get a repair scheduled before you need it to keep the house warm.

Here’s how to run the test:

Step one: Install a new filter. A clean filter keeps airflow steady and makes any unusual smells easier to trace.

Step two: Set the thermostat to heat. Raise your thermostat about five degrees above room temperature so the furnace kicks on and runs long enough to test.

Step three: Listen to the startup. You should hear the motor hum, then the igniter click or glow, then the burners light. The blower follows within a minute or two.

Step four: Feel the vents for warm air. Put your hand up to vents in a few different rooms and check airflow. Warm air should reach the closest vents within a few minutes.

Step five: Let it finish a full cycle. The furnace should shut off on its own once the room reaches the set temperature. If it keeps running past that point, the thermostat or a control may need a closer look.

When to shut it off and call a local HVAC company

If you notice any of the following during the test run, shut the furnace off and contact a local HVAC company:

• A hot plastic or electrical smell that doesn’t fade within a few minutes
• Burners that repeatedly light and shut off within seconds
• Yellow or flickering flames instead of steady blue ones
• A loud bang or boom when the burners ignite
• A musty smell that keeps coming back

Notice a rotten-egg-like smell? Gas companies add that scent to natural gas so leaks are easy to notice. If you smell it, immediately leave your house and call Atmost Energy or 911 from outside. Once the gas company confirms your home is safe, have an Amarillo Air technician inspect the furnace before you turn it back on

Furnace Tune-Up Checklist: What a Professional Should Check

A professional furnace tune-up checklist covers the safety and combustion checks that aren’t safe to do on your own. A qualified pro should clean and inspect your equipment every year, and it’s a good idea to book a visit soon after moving into a new home.

A thorough tune-up should include:

• Inspecting the heat exchanger for cracks
• Cleaning the flame sensor and checking the igniter
• Testing gas pressure and adjusting the burners
• Running a combustion test on the flue gases
• Checking the venting and draft
• Testing the limit switches and other safety controls
• Measuring the blower motor’s amp draw
• Tightening electrical connections
• Clearing the condensate drain on high-efficiency models
• Confirming the thermostat reads and cycles properly

Routine professional tune-ups keep your furnace running safely. Technicians locate any minor issues before they cause a breakdown, and catch safety problems before they put your family at risk. You’ll also get a written report at the end of the service, which gives you a baseline for future calls and proof of maintenance if you need warranty coverage.

Furnace Maintenance Considerations in Amarillo, TX

Amarillo homeowners deal with strong winds and high elevation that affect how a furnace runs. Strong gusts carry dust and soil into the house, and your furnace filter catches most of it. That buildup can clog the filter and eventually make the furnace overheat and shut off.

At around 3,600 feet, Amarillo’s thin air also changes how gas burns. Technicians check gas pressure and burner settings against the altitude so your furnace burns safely. 

Warning Signs Your Furnace Needs Attention Now

Furnaces often give off warning signals, like strange sounds or a sudden jump in your gas bill, when something is wrong. You may need repair or replacement if:

• Cold air is blowing from the vents while the furnace is running.
• The furnace is turning on and off every few minutes.
• Water is pooling around the base of the unit.
• Soot or rust is around the flue pipe or burner.
• The unit makes banging, squealing, or grinding noises.
• Gas bills are rising without a change in how you use heat.

Frequently Asked Questions

How often should I change the filter in Amarillo?

Most furnace filters in Amarillo need replacing every 30 to 60 days because of wind-blown dust. Check your filter every month during the heating season, and replace it if it looks gray or you can’t see light through it. 

How much does a furnace tune-up cost?

The cost of a furnace tune-up depends on the type and age of your system. Our team provides upfront quotes before any work and offers maintenance plans that cover yearly service for a small annual fee.

Does skipping maintenance void my warranty?

Skipping maintenance can void your warranty with many manufacturers. They’ll often require proof of annual professional service before covering parts, so book regular service and keep your service reports on hand.

How long does a tune-up take?

Most furnace tune-ups take an hour to an hour and a half. Older systems or furnaces in tight attic spaces can take a bit longer to service.

When should I replace instead of repair?

Replacement makes sense when your furnace is over 15 years old and needs a major repair, or when repairs cost more than half the price of a new unit. Our technicians can look at its age and repair history and give you an honest recommendation.
