GAS FURNACE INSPECTION CHECKLIST – DIY
Every homeowner should know how to spot serious trouble and know when to call an expert for help. Follow these helpful rules to get the most out of your gas furnace, and stay safe doing it. Because most furnaces are hooked up to your home gas line, we recommend calling an expert if you spot any issues.
If you are performing any kind of gas furnace maintenance, turn off the gas line. The valve to turn off your gas line should be located near the gas meter.
Look at the flames in the burner. You should see a steady blue flame. If you see yellow or orange flicking, call a specialist to determine if something other than natural gas is burning.
Listen for questionable noises or vibrations while the furnace is on. If you hear any unusual sounds, ask your technician for guidance.
Smell for any gas leaks. If you smell gas, do not try to light any appliance. Do not touch any electrical switch. Do not use a phone in your building. Immediately call a gas supplier from your neighbor’s phone. Remember, you may not be able to smell fuel gases. Carbon monoxide detectors are recommended and should be installed according to all local laws and regulations.
In the event that electrical, fuel or mechanical failures occur, immediately turn the gas supply off at the manual gas valve on the gas pipe before turning off electrical power to the furnace. Contact a qualified service agency as soon as possible.
Do not use this unit if any part has been under water. A flood damaged unit is extremely dangerous. Attempts to use the furnace can result in fire or explosion.
GAS FURNACE MAINTENANCE SCHEDULE
SERVICING YOUR GAS FURNACE – DEALER CHECKLIST
Schedule a preventative maintenance checkup with your local dealer every fall before winter weather arrives. Here’s what your dealer will do during your gas furnace service appointment.
- Confirm all flue product carrying areas external to the furnace (chimney, vent connector) are clear and free of obstruction.
- Confirm vent connector is in place, slopes upward and is physically sound without holes or excessive corrosion.
- Check the return air duct connection(s). Should be physically sound, sealed to the furnace and ends outside the space containing the furnace.
- Check furnace support structure. Should be without sagging, cracks or gaps around the base.
- Confirm the burner flames are in good adjustment without erratic flames.
- Inspect fresh air inlet and vent and remove any obstructions. The horizontal or vertical vent and inlet must be located at least 12 inches minimum (18 inches in Canada) above the normally expected snow accumulation level.
CHANGING YOUR GAS FURNACE FILTER
CLEAN OR REPLACE YOUR FILTER REGULARLY
Taking care of the filter is one of the most important things you can do for your furnace. As the system circulates air, it filters the air in your home and extracts excess moisture to help control humidity.
WHY SHOULD I CHANGE MY AIR FILTER
When your furnace circulates the air in your home, dust and dirt particles build up on the filter. Excessive accumulation can block the airflow, forcing your furnace to work harder to maintain a constant temperature. The harder your unit has to work, the more energy it uses.
HOW OFTEN SHOULD I CHANGE MY AIR FILTER?
The easy answer is to change your filter when it gets dirty. For every home and homeowner, how quickly your filter gets filled up depends on several factors like home size, pets and others. But here are a few guidelines to follow:
- Home with no pets: every 90 days.
- Home with one pet: every 60 days.
- Home with more than one pet or people with allergies/asthma: every 20-45 days
HOW DO I CHANGE MY AIR FILTER?
First, find out where the filter is located in your system and then follow these steps. If you have any questions, contact your local Trane Dealer.
- Turn off your furnace.
- Find out your furnace filter size.
- Remove old filter.
- Insert new filter (make sure you follow the air flow arrows).
- Turn back on furnace.
