SIGNS YOU NEED FURNACE MAINTENANCE
Fix Common Furnace Issues
After years of repairing furnaces, our team has come across a variety of furnace problems that our customers have experienced. While there are instances where you can try and fix it yourself, it’s safer to call or schedule your furnace repair in Calgary with One Stop HVAC.
Furnace won't turn on
Cause: Most of the time, this happens because the furnace isn’t getting power. It could be a tripped breaker, a blown fuse, the switch near the furnace being off, or dead thermostat batteries. Sometimes, though, it’s an internal control issue or a safety sensor preventing the furnace from starting.
At Home Fixes: Check that the switch near the furnace is on, reset any tripped breakers, and replace thermostat batteries.
When You Need Us: If the furnace still won’t start, there could be an internal electrical or control problem. Handling this safely requires a licensed HVAC technician.
Furnace not blowing hot air
Cause: This usually comes down to airflow or heat generation issues. A clogged air filter, malfunctioning burners or ignitor, or problems with the gas supply can prevent the furnace from heating the air.
At Home Fixes: Replace or clean the air filter and make sure the gas valve is on (for gas furnaces).
When You Need Us: If air is still cold, the burners, ignitor, or gas line may need professional attention. Only a licensed technician should handle these parts to avoid injury.
Furnace keeps turning on and off
Cause: Short-cycling often happens because airflow is restricted by dirty filters, blocked vents, or duct issues. It can also be caused by overheating or a thermostat that’s misreading the temperature.
At Home Fixes: Replace the air filter and make sure all vents are open and unobstructed.
When You Need Us: If the furnace keeps cycling, it likely needs professional inspection for blower issues, safety switches, or thermostat calibration.
Furnace is louder than normal
Cause: Unusual noises usually come from loose panels, ductwork issues, delayed ignition, or a failing blower motor or fan belt.
At Home Fixes: Tighten any loose panels and make sure vents are secured.
When You Need Us: Persistent banging, squealing, or rattling requires a professional to inspect the internal components safely.
Furnace overheating
Cause: Overheating is often caused by restricted airflow, dirty filters, blocked vents, or malfunctioning blowers. It can also be due to a limit switch issue, which is the furnace’s safety sensor.
At Home Fixes: Keep filters clean and vents clear to allow proper airflow.
When You Need Us: If your furnace actually starts to overheat, stop using it and call a technician. Running an overheating furnace can cause serious damage or safety hazards.
Furnace filter getting dirty too fast
Cause: Filters clog quickly when there’s extra dust, pets, or duct leaks allowing debris into the system.
At Home Fixes: Replace filters more frequently. Vacuum around vents and keep the area clean.
When You Need Us: If filters continue to clog unusually fast, a technician can inspect the ductwork and system to find hidden leaks or other issues.
FREQUENT QUESTIONS FROM OUR CUSTOMERS
Furnace FAQs
How much does it cost to repair a furnace in Calgary?
The cost of replacing a furnace can vary depending on several factors, including the type of furnace, the size of your home, and any additional installation requirements.
It’s best to consult with a One Stop HVAC technician who can provide you with a more accurate estimate based on your specific needs at (587) 227-7847.
In general, your repair will be around $150 to $500 Canadian dollars.
How long will it take your furnace repair technician to show up?
In most cases, our furnace repair technician can arrive the same day, often within a few hours of your call during regular service hours. Because we’re located south of central Calgary, we’re well-positioned to reach homes across the city and nearby communities without long delays.
Do I have to pay extra for weekend service?
No, we charge the same price on weekends as we do on week days.
How long will it take to repair my furnace in Calgary?
Many common furnace repairs can be completed in a single visit, often within a few hours. Repair time depends on the issue and part availability, but we aim to restore heat as quickly as possible.
How long will it take for the parts needed for my furnace repair to arrive?
In many cases, our technicians carry the most commonly needed furnace parts with them, which means repairs can often be completed the same day. If a specific part needs to be ordered, delivery typically takes 1 to 3 business days, depending on availability and the furnace make and model.
For older or specialty systems, some parts may take a bit longer. Our team will always explain timelines clearly and keep you updated throughout the process of your repair.
Do you give warranty on repairs in Calgary?
Yes. We back our furnace repairs with a comprehensive 3-month labour warranty, so if an issue related to our work arises within that time, we’ll take care of it.
In addition, many replacement parts come with a 10-year limited product warranty from the manufacturer. Together, this guarantees both the workmanship and the parts used in your repair are properly protected!
How do I know when my furnace needs repairing?
Knowing when it’s time to replace your furnace is an important decision. While repairs can often address minor issues, there are signs that indicate it might be more cost-effective and practical to invest in a new furnace. Here are a few indications that it may be time to consider a replacement:
- Age of the furnace
- Rising energy bills
- Frequent repairs
- Uneven heating
- Excessive noise
We recommend consulting with a One Stop HVAC technician for a professional evaluation of your furnace. They can assess its condition, consider its efficiency, and provide you with an informed recommendation on whether a repair or replacement is the best course of action for your specific situation.
Why does my furnace struggle more during Calgary cold snaps than mild winter days?
As expected with Calgary’s brutal winters, extreme cold puts maximum demand on your system. Older furnaces, restricted airflow, or minor component issues often only show up when temperatures drop sharply.
Is it normal for my furnace to run almost nonstop during deep freezes in Calgary?
Yes, to a point. During extreme cold, longer run times are normal.
However, if your furnace never reaches the set temperature or sounds strained, that’s a sign that something isn’t operating efficiently.
Why does my furnace sound louder when it’s really cold outside?
Cold temperatures cause metal components and ductwork to contract, which can increase noise. Light popping or expansion sounds can be normal, but banging, grinding, or screeching is not and should be checked.
Why does my furnace keep turning on and off every few minutes?
This is called short cycling, and it’s often caused by overheating, airflow problems, dirty filters, or thermostat issues. Left unaddressed, it increases wear and can lead to system failure.
Can a dirty furnace filter cause my system to shut down?
Absolutely. A clogged filter restricts airflow, causing the furnace to overheat and trigger safety shutoffs. This is one of the most common and preventable furnace issues we see in Calgary.
What is the average life expectancy of a furnace in Calgary?
Most furnaces last 15 to 20 years with proper maintenance. Calgary’s long heating season can shorten the lifespan of systems that aren’t serviced regularly or are constantly overworked.
How can I avoid frequent repairs?
While it’s impossible to completely eliminate the potential for furnace repairs, there are several steps you can take to minimize the likelihood of unexpected breakdowns and prolong the lifespan of your furnace. Here are some tips to help you avoid furnace repairs:
- Regular maintenance
- Clean and replace air filters
- Keep vents clear
- Pay attention to any unusual noises, odours, or changes in your furnace’s performance
- Avoid overworking your furnace
By following these preventive measures and being attentive to your furnace’s condition, you can significantly reduce the chances of unexpected repairs. However, it’s important to remember that regular professional maintenance remains crucial to ensure the optimal performance and longevity of your furnace.
