Why is My Furnace Not Working or Turning On?

No comments

One phrase every home owner dreads saying is, “Why is my furnace not turning on?” A non-functional furnace is incredibly inconvenient, and for most of us, brings to mind thoughts of costly repair bills and expensive furnace replacements. On top of this, your home is getting colder by the minute, and all you want is for your furnace to start working again to warm you up.

When your furnace isn’t working, it’s important to stay calm and start troubleshooting potential problems. Here, we’ve gathered some of the most common reasons that a residential furnace may not be working properly or turning on:

  1. Dirty Furnace Filter
    A furnace filter that is full of dust and debris can block air flow throughout your home, preventing it from heating. Buy the correct filter for your furnace model and replace the dirty one with a fresh, clean one to ensure proper air flow.
  2. Thermostat Settings
    Likely one of the easiest troubleshooting steps, checking your thermostat settings is essential. Make sure that your thermostat is set to “heat”, not “cool”.
  3. Furnace Power is Off
    If you haven’t used your furnace in a while, the power may still be shut off. Check that the power switch is on.
  4. A Tripped Breaker
    A tripped circuit breaker could prevent your furnace from turning on. Look at your electrical panel and see if the breaker may have been tripped. Flip it back to the “on” position if it is set to “off”.
  5. Gas Supply Issue
    Check to see if the gas supply valve is turned to the full “on” position so that your furnace has sufficient fuel to turn the system on and operate correctly. Your gas valve should always be turned fully on or fully off, never in an in-between position.
  6. Complete Breakdown
    In some cases, your furnace may not work or turn on because of a complete breakdown. If your furnace has not been maintained properly, an unexpected failure can occur as a result of a damaged or improperly functioning component.

Should these troubleshooting tips leave you still wondering, “Why is my furnace not working?” you’ll need to call a trained professional to inspect your furnace and diagnose the issue. Attempting to repair your furnace on your own is not recommended.

Troubleshooting a Gas Furnace: No Heat

No comments

It always seems to happen at the worst time – your gas furnace simply stops heating, and it’s freezing outside! You might find that your furnace is blowing cold air, or perhaps it isn’t blowing any air at all. In either case, you’re likely wondering how you can get it back up and running properly, and fast!

Luckily, there are a number of DIY steps you can take in troubleshooting a gas furnace with no heat. Evam Canada has created this simple checklist to help you through the no heat troubleshooting process:

  • Check your thermostat. This may seem obvious, but if your thermostat is not set to “heat” mode, it won’t heat your home. Try turning the temperature up a few degrees at the thermostat to see if it triggers your furnace to blow hot air.
  • Make sure the furnace is getting power. If the thermostat trick didn’t work, check to see that a breaker hasn’t been tripped at the panel.
  • Some furnaces have a “reset” button located on the indoor component in your basement. Press the button to restart your furnace, which may resolve the issue.
  • Check your furnace filter to see if it is clogged or dirty, which could be blocking air flow throughout the rest of your home. If it is dirty, replace it with a fresh filter.
  • Go around your house and ensure all heat registers are open. If there is any furniture or clutter blocking the registers, clear it away as this can cause your furnace to work harder than necessary.
  • See if the pilot light is out. When troubleshooting a gas furnace with no heat, the pilot light being out is a very common culprit, especially in older models. Re-light it if needed.
  • Check the fuel supply source. Is the natural gas source turned on? A shut off gas supply valve will mean that your furnace cannot run.
  • Examine your ductwork. Major holes or leaks in your ducts could make it seem as if your furnace isn’t producing heat at all. Repair or replace ducts as needed.
  • Check the condensate line. Some newer furnace models will automatically shut off if a sensor determines that the condensate line has become clogged.

Completed the checklist but still have no heat? Evam Canada can get your home cozy and warm again in no time. Our emergency furnace repair services are available in Mississauga and across the GTA so you can restore your gas furnace back to working order.

Furnace Vibration Noise: Troubleshooting Tips

No comments

Is a furnace vibration noise disturbing your peace and quiet? Noticing a vibration sound coming from your heating equipment is a common complaint we hear from home owners about their old and new furnaces alike. Unfortunately, it can be difficult to pinpoint the exact cause of the vibration, since there are many potential problems that could be causing it.

In order to troubleshoot your furnace vibration noise, there are a number of DIY steps you can take at home. Here, we’ll explain the most common furnace problems that could be the source of the annoying vibration sound. Before shutting off your furnace to examine the problem, try to diagnose exactly where the sound is coming from so you can start your search in that area. Ensure your furnace is turned off completely before you attempt any of the following:

Unbalanced Blower Motor

There could be something off-balance within your blower, causing the fan to make vibrating sounds when it spins. Check the fan and motor for signs of dust or debris build-up or any other kind of obstruction and clear it away to see if the problem has been solved.

Loose Fan Mounts

Loose fan mounts are especially common in older furnace models, which have circulation fans mounted directly to the furnace cabinet using metal supports. When the fan turns on, vibrations occur from the fan and motor as the support rattle. The mounts may be loose or corroded and require tightening and/or replacement to make sure the fan operates smoothly again.

Loose Access Panels

Loose parts on your furnace’s housing can cause an annoying vibration sound when the furnace is running. You can fix this problem by carefully tightening all bolts and screws on the exterior of your furnace. Check access panels to make sure they are closing properly and sitting in their frame correctly.

Vibrating Duct Work

Should your furnace be vibrating near duct work, it could be the ducts themselves causing the sound as air passes through them. You can test to see if your ducts are the source of the noise by putting pressure on the side of the duct with your hand. If this stops the vibration, you can check the seams and seals of your ducts to repair any loose connections.

If your furnace vibration noise is bothering you, put a stop to it by contacting Evam Canada. Our emergency furnace repair technicians are on hand to diagnose your furnace’s issue and restore it to normal working order.

Furnace Exhaust Fan Noise: Troubleshooting Tips

No comments

When your HVAC system is making unfamiliar or loud sounds, it can be a cause for concern. Not only are furnace exhaust fan noises disruptive, they may also indicate potential problems within your furnace that need to be repaired immediately.

A furnace exhaust fan in need of repair is of particular concern, since it is such a critical component of your system. The exhaust fan is designed to draw out the exhaust fumes that are created when the natural gas or oil fuel source is burned to heat your home. If you notice unusual sounds coming from your exhaust fan, we recommend performing these steps to troubleshoot the issue:

  1. Inspect the Fan
    While your furnace is powered on, take a look at how your fan is running to see if you can pinpoint exactly where the noise is coming from. This will help you diagnose the issue and know exactly where to start looking.
  2. Clean the Fan
    After turning off your furnace completely, examine the fan for dirt and debris, and clean it if necessary. Also check that the fan turns easily. If you find it is stiff, lubricate the fan wheel with an appropriate lubricant. Check your furnace’s manual for further details.
  3. Look for a Loose Belt
    A loose fan belt can cause the fan to turn off-balance and make unwanted noises. Replace a loose belt with the correct model, ensuring it is correctly seated in the belt groove so that the fan can rotate smoothly.
  4. Poor Installation
    Your exhaust fan and motor may have been installed incorrectly, causing abnormal noises during operation. If you suspect that it has been installed poorly, have a service technician come and inspect the exhaust fan and motor to recommend a solution.
  5. Worn-Out Motor
    A worn-out exhaust fan motor can cause the components to operate at less-than-optimal performance. In most cases, a repair to your exhaust fan motor requires a complete replacement of the fan and related components, which should be handled by a pro.
  6. Replace
    If the above DIY furnace repair steps did not address the furnace exhaust fan noise, it’s time to call in a professional. You may require a full replacement of the exhaust fan components to resolve the noise issue and restore your furnace to its maximum efficiency.

Evam Canada is here to help you put an end to annoying furnace exhaust fan noises. If you’re still not sure how to fix your noisy equipment, our emergency furnace repair specialists can help and make your home comfortable and quiet again.

Why Does My Furnace Shut Off Before Reaching the Temperature I’ve Set?

No comments

Has your furnace stopped blowing warm air before it reaches the target temperature? If you find yourself thinking, “Why does my furnace shut off before reaching the temperature I’ve set”? You are not alone. This is a very common furnace problem, and can be very frustrating if you are trying to maintain a comfortable indoor environment at just the temperature you like.

In this article, we’ll review some of the reasons your furnace may be shutting off before it reaches its target temperature.

Thermostat Problem

You may simply need a new thermostat to resolve your problem. This is especially true if you have an older dial-type thermostat, which may be calibrated incorrectly. It may also have become less accurate over time as its components age. Pick up a new thermostat and replace your older model to see if this solves the problem.

Sensor Problems

There may be something causing a sensor to turn off the furnace after reaching a certain temperature. A malfunctioning, blocked or dirty flame sensor could be the issue. Luckily, this is easily resolved by maintaining a regular furnace maintenance schedule to ensure your flame sensor stays free of dust and debris.

Blocked Airflow

A lack of airflow can cause your furnace to stop heating before reaching the set temperature. Ensure there is nothing impeding airflow around your furnace, within your furnace and through your ducts. Check that registers are open, no ducts are damaged or crushed and replace your furnace filter. Inside your furnace should be clean and free of debris, especially around the blower motor and the heat exchanger. Move any furniture, boxes or other objects away from the furnace itself.


If your furnace is overheating, it could be shutting off prematurely before it reaches your desired temperature when the temperature safety limit is reached. Ensure that your furnace filter is clean and there are no other obvious signs of broken or loose parts inside your unit. If the problem is still occurring, shut off your furnace and call a professional for service. An overheated furnace can be extremely dangerous and can cause further damage if the problem is not addressed.

Are you still wondering, “Why does my furnace shut off before reaching the temperature I want”? The HVAC team at Evam Canada can answer your questions and diagnose and repair any furnace issues you may be experiencing. To book an appointment, contact us online or give us a call at 905-624-5544.

Why Does My Furnace Keep Turning On and Off?

No comments

One of the most common furnace troubleshooting questions we hear from our customers is, “Why does my furnace keep turning on and off?”. Normally, furnaces should cycle on only when the temperature in your home is lower than the pre-set temperature you have input at the thermostat. When the desired temperature is achieved, your furnace should turn off and only turn back on when required to bring the temperature back up.

However, some homeowners may find that their furnace is constantly cycling on and off, which can become more than just an annoyance – it can also indicate a serious problem. Luckily, there are some simple explanations for why this might be happening with your furnace:

Thermostat Errors
If your thermostat is faulty or is set incorrectly, your furnace may be signalled to turn off and on more frequently than necessary. Carefully review your thermostat’s settings and make sure they are correct. Next, consider the placement of your thermostat in your home, and move it if it is close to a heat source or direct sunlight, which may be signalling your furnace to shut off. A furnace turning on and off can also be the result of a faulty thermostat, so it may need to be completely replaced.

Short Cycling
Short cycling is often the number one answer to the question, “Why does my furnace keep turning on and off?”. Short cycling usually involves issues with the furnace itself, starting with a simple dirty air filter to a major issue with the circuit board. There are many other serious furnace issues that can cause short cycling, such as:

  • Cracked heat exchanger
  • Improper or clogged venting
  • Malfunctioning inducer
  • Dirty flame rods
  • Improperly sized furnace
  • And more

These are just some of the issues that can cause your furnace to overheat, thereby triggering safety measures which shut off your furnace. Once it cools down, the furnace will start up again and the cycle will repeat over again until the problem is resolved.

Our team recommends seasonal furnace maintenance to avoid these potential furnace issues and to prevent short cycling from occurring in the first place. Regular tune-ups and/or replacement of broken and damaged components can ensure your furnace keeps running efficiently.

If you are still left asking, “Why does my furnace keep turning on and off?” we are here to solve the problem. Evam Canada is pleased to offer emergency furnace repair services to Mississauga and GTA residents. Our technicians are available around the clock to quickly respond to your furnace issues when you need us most!

What is a Furnace?

No comments

A furnace is a type of heating equipment used in residential homes and commercial properties to keep the indoor climate comfortable during the cooler months of the year. Adding heat to your home in an affordable and reliable way is important for many homeowners, which is why furnaces are the heating method of choice across Canada when compared to less convenient and often costly alternatives like electric baseboard heaters, space heaters or wood stoves.

The furnace is a vital component of any heating system, and knowing a little bit about how they operate can help you choose the right model and make sure your furnace is always operating efficiently. Read on to discover more about furnaces and how they work to keep your home warm.

What is a Furnace and How Does it Work?

If your home has central heating, you may be wondering just how your furnace operates. So, what is a furnace good for besides taking up space in your basement? A furnace is the most critical component of your property’s HVAC system, keeping you comfortable all year around.

Your furnace is made up of three primary parts: The burner, heat exchanger and blower. The burner ignites the fuel source (usually natural gas) via the pilot light, and begins to warm the heat exchanger to the desired temperature. Once this temperature is reached, the blower will force air overtop the heat exchanger and transfer it through the ductwork and vents within your home.

When you adjust the thermostat, your furnace adjusts accordingly to deliver air at exactly the temperature you want. If you’ve set your thermostat to maintain a particular temperature, it will turn on any time it senses that the room temperature is below the pre-set temperature.

Types of Furnaces

There are several types of furnaces, but the most common type is the gas furnace. Gas furnaces are one of the most effective and energy-efficient ways to heat your home. Most furnaces operate in the same way, but may use a different fuel source. Less common furnace fuel sources include oil, propane and electricity. Aside from using various sources, furnaces are available in single-stage, two-stage and variable speed operation modes. There are also a broad range of efficiency levels when it comes to the furnaces on the market today.

There are many factors that will determine which type of furnace is right for you, depending on the size of your home, average climate in your area, your existing HVAC system as well as your budget. The best way to discover the right furnace for your home is to consult with a furnace specialist who can recommend equipment that suits your needs.

Looking for more information about furnaces? We can answer all your questions, including, “What is a furnace?” and “Which furnace is right for my home?”. The furnace experts at Evam Canada are available to help you select the ideal furnace according to your heating needs and desired efficiency rating. Contact us today for more details!

How to Service a Gas Furnace

No comments

Regular maintenance is key to prolonging the life of your furnace, making sure that it works well for many years to come. Whether you choose to perform your furnace maintenance annually or seasonally, by yourself or with the help of an expert, it is important that you thoroughly service your equipment to keep it in top condition.

The experts at Evam have put together these tips on how to service a gas furnace at home so you can enjoy a trouble-free heating season this year! Remember, before performing any of these maintenance tips, always shut off your furnace for safety reasons.

  1. Change the Air Filter

While this is an obvious gas furnace maintenance step, many home owners do not change their air filter often enough. Since dirt and debris in the filter can greatly reduce the efficiency of your furnace, be sure to change your filter regularly, especially during the heating season.

  1. Get Vacuuming
    Open your furnace and vacuum around the blower motor to remove dust and debris. Next, vacuum around the exterior of your gas furnace. Finally, vacuum all of the air registers around your home to make sure they are clear as well. Any blockages can restrict airflow and cause your furnace to be less efficient.
  2. Lubricate the Blower Motor
    A well-lubricated and clean blower motor works more efficiently and stays cool. While many gas furnaces feature permanently lubricated motors, others have oil ports above the bearings that need to be tended to on an annual basis. Add a few drops of non-detergent motor oil to each oil port. Always consult your furnace manual or a professional if you aren’t sure what type of oil to use.
  3. Clean the Pilot Light, Flame Sensor & Igniter
    Use a drinking straw to blow dust off of the pilot light and igniter, and use an emery cloth to remove dust and carbonization from the flame sensor. Dirty pilot lights, igniters and flame sensors can cause issues with your furnace not turning on, or prevent it from heating cool air.
  4. Inspect All Components
    Look at the heat exchanger, blower motor, fan belts, condensate line and more for signs of rust, cracks, holes and general degradation. If you notice any of these signs, be sure to call in an HVAC repair technician to handle these more difficult service tasks and repairs.

Not sure how to service a gas furnace? At Evam Canada, we offer hassle-free gas furnace maintenance plans that will keep your equipment working efficiently! Our expert furnace service technicians are familiar with all makes and models, and can handle everything from minor repairs to the installation of a brand new furnace.

Can I Perform My Own Gas Furnace Maintenance?

No comments

Plenty of homeowners wonder if they can DIY their furnace maintenance tasks to save time and money. But is this a good idea? A furnace is a complex piece of equipment. When you add to that the dangers related to its fuel source, natural gas, there is a lot of room for error when it comes to performing your own gas furnace maintenance.

Most HVAC companies do not recommend that you perform repairs or complicated maintenance on your gas furnace. It is wise to leave these tasks to the experts who know how to safely handle heating equipment and work with natural gas.

However, there are some gas furnace maintenance tips that you can do on your own. The following is a list of basic and safe furnace DIY tips you can use at home:

  • Perform a visual inspection. Look at the exterior of your furnace, checking for black soot, corrosion or leakage, which can be signs of major problems.
  • Check the pilot light. If the pilot light is not burning, follow the instructions in your furnace manual to relight it. If it still does not ignite, call a professional for assistance.
  • Check the burner flames. Visually examine the flames inside your furnace, which should be steady and blue in colour. If you see yellow flames, this could indicate that the burners are dirty. Call a professional for assistance.
  • Clean the flame sensor. Over time, residue can build up on the flame sensor, which can cause your furnace to shut off and on repeatedly. Use a piece of light grit sandpaper or steel wool to clean the sensor.
  • Check your thermostat. If you find that the indoor temperature is not quite comfortable, there may be an issue with your thermostat. Test it by raising and lowering the temperature a few degrees and see how your furnace adjusts. The thermostat may need replacement if there is no response.
  • Repair the ductwork. If you notice any air leaking from connections in your ductwork, repair them with foil tape. For larger holes, you may need the help of an expert to patch or replace sections of ductwork.
  • Replace your air filter. Your gas furnace’s air filter should be replaced at the beginning of the heating season, and on a monthly basis throughout periods of peak usage. A clean filter is essential for proper airflow and healthy, clean air.
  • Check for gas leaks. If you notice any natural gas smells near your furnace, always call your local gas company immediately to shut off the gas safely.

Not sure if you need an expert to handle your gas furnace maintenance? We’d be happy to help! Contact Evam Canada today for all your furnace maintenance and repair needs in Mississauga and beyond. Schedule your service now by calling us at 1-905-624-5544 or contact us online.

Furnace Troubleshooting: No Heat!

No comments

Finding that your furnace is failing to produce warm air is one of the biggest issues home owners can encounter when it comes to their HVAC system. Your furnace may be running, but blows cold air instead of hot. Or, your furnace may not even turn on at all.

In either case, furnace troubleshooting no heat-related problems is something you’ll want to get fixed fast, especially during the colder months of the year. Read on for our tips on diagnosing and resolving your furnace troubleshooting “no heat” issue:

Furnace Troubleshooting: No Heat

Is your furnace running, but simply not heating? If you find that cold air is coming from your registers instead of warm, your furnace is likely just recirculating the air within your home without heating it up first. Run through the following checklist first to see if any of these problems are the culprit:

  • Is your thermostat set to heating? Try raising the temperature a few degrees and see if the furnace starts blowing warm air.
  • Are your registers open? Make sure they are open and not blocked by furniture.
  • Is the breaker that controls your furnace tripped? If so, reset the breaker.
  • Is your furnace filter dirty? Clean or replace the air filter.
  • Is the pilot light out? Re-light it if you are comfortable doing so. If not, call your local HVAC company for help.

Once you’ve double-checked all of these potential issues and ruled each of them out, it’s likely time to call in a professional. Further fixes and repairs can be dangerous and should only be performed by an experienced HVAC technician.

Furnace Troubleshooting: Furnace Won’t Turn On

You might find that not only is your furnace not heating, it is not turning on at all. If this is the case, start by making sure the furnace is set to “ON” and its breaker is not tripped. You’ll also want to check that the condensate pan is not full, and that the furnace’s air filter is clean – both of these issues may result in your furnace not turning on. If after checking all of these areas your furnace is still not turning on and blowing hot air, turn to a professional for assistance with troubleshooting.

If you still haven’t resolved the problem with your furnace, remember that your local Mississauga furnace troubleshooting experts are here to help. Evam Canada’s trained furnace repair specialists have experience with all makes and models, and will fix your heating problem so you can enjoy a warm and cozy home.
