If a heating system has been sitting unused for months, it may need a bit of simple maintenance before it can maintain normal temperatures. This is especially helpful in Calgary, since the heating system could be operating for longer durations when it’s cold.
Examine furnace filter
Start with the filter. You might assume that your furnace is not used frequently, so this is unnecessary. However, dust and debris can still accumulate in it even when it’s not in use.
A dirty filter may limit airflow. This may force the system to operate harder. So, replace it. Check the recommended type for your furnace.
In addition, regularly inspect it during the heating season. Especially if dust is a problem in your house.
Check vents and registers
This is the time to take a walk around your home. Inspect the air supply vents and return registers. They should be open and unobstructed.
Airflow can be restricted by:
- Furniture
- Curtains
- Rugs
- Debris, etc.
Maintain clear space in these areas. This enables heated air to flow more freely. You also get the chance to observe if some rooms have poorer air movement than others.
Check the thermostat
Test your thermostat before the winter season. Change batteries as needed. Also, ensure that the system cycles from heating to other modes as desired.
Another way to test the furnace is to increase the temperature a few degrees above the room temperature. Allow the system to run for a while and see if warm air is delivered to the vents after some time.
Listen for unusual sounds
Listen for the furnace starting. Some operational noise is normal. But beware of loud:
- Banging
- Scraping
- Grinding
- Clicking.
These sounds could indicate a mechanical problem.
It might be easier to diagnose the problem early than when the system fails during extremely cold weather.
Inspect around the furnace
Keep furniture and other stored items away from the furnace area. NEVER stack boxes, cleaning supplies, clothes, or household items directly on equipment.
Inspect for visible signs of damage. If you detect a strong gas odor, pay more attention. However, do not try to investigate or repair the furnace yourself. Evacuate and call an emergency technician.
Consider a professional inspection
Basic checks can help. But they won’t catch every furnace issue. A professional inspection could be worth considering before winter demand rises if:
- Your system is older
- Has previously experienced issues
- Is making unusual noises.
When arranging an inspection or repair, look for experienced furnace repair companies in Calgary.
The last words
It doesn’t take much to prepare your furnace for winter. You only need to perform these basic checks and leave a professional to handle the rest. But more importantly, when you look into the problem early, you can solve the issues before you depend on your furnace daily.
