Fall is here, and before your furnace settles into months of regular use, this is a good time to make sure it is ready for the heating season ahead.

For a limited seasonal opportunity, Don’s Heating & Cooling is offering a professional furnace tune-up for just $79.

If your furnace has been sitting mostly unused throughout the summer, an early-fall check can help identify potential concerns before you are relying on it every day. It is also much easier to deal with a furnace issue now than on the first truly cold night of the season.

Homeowners in Orangeville, Alliston, New Tecumseth and surrounding communities can book the $79 furnace tune-up and get their heating system ready before winter arrives.

Why Fall Is a Good Time to Check Your Furnace

Your furnace can go several months without doing much work. Then, as temperatures fall, it suddenly becomes one of the hardest-working systems in your home.

That transition makes fall an ideal time to pay attention to how your heating system is performing.

Natural Resources Canada recommends having heating systems checked before the heating season and notes that fall is a good time for a professional heating-system check-up.

A pre-season furnace check gives you an opportunity to spot issues while temperatures are still manageable instead of discovering them after your furnace has stopped heating your home properly.

It can also help you start the season knowing that important components of your heating system have been professionally examined.


Why a $79 Furnace Tune-Up Can Be Worth Doing Before Winter

It is easy to postpone furnace maintenance when everything appears to be working normally.

The problem is that many furnace issues do not begin with a complete breakdown. You may first notice longer heating cycles, unusual sounds, weaker airflow, inconsistent temperatures or a furnace that behaves differently from last winter.

A professional tune-up provides an opportunity to look at the system before a small concern becomes much more inconvenient.

At $79, Don’s Heating & Cooling’s current furnace tune-up offer makes early-fall maintenance an affordable step toward preparing your home for another Ontario heating season.

What Does a Professional Furnace Tune-Up Look For?

A furnace is more than a box that produces warm air. It contains electrical components, controls, airflow components, combustion-related parts on fuel-burning systems, safety devices and other components that need to work together properly.

Depending on the type, condition and configuration of your furnace, a professional HVAC inspection may involve checking areas such as:

  • thermostat operation and furnace start-up
  • electrical connections and system controls
  • airflow and the condition of the furnace filter
  • blower operation
  • burners and ignition components on applicable systems
  • venting and combustion-related components
  • condensate drainage on applicable high-efficiency equipment
  • safety controls
  • unusual sounds, wear or visible signs of deterioration

The exact work required can vary by furnace, so your technician can explain what is appropriate for your particular system.

Natural Resources Canada also recommends regular professional HVAC check-ups and identifies electrical connections, system controls, condensate drainage, gas or oil connections, burner combustion and heat exchangers among the areas that may need professional attention.

7 Things Homeowners Can Check Before Turning the Furnace On for Winter

A professional furnace tune-up handles the technical side of the system, but there are also several simple things you can check around your home.

1. Check Your Furnace Filter

Start with the filter.

A dirty or heavily loaded filter can restrict airflow and make it harder for your HVAC system to move conditioned air through your home.

Natural Resources Canada recommends inspecting, cleaning or replacing furnace filters regularly and following the furnace manufacturer’s instructions.

If you are not sure which filter you need or how to install it correctly, read our step-by-step guide on how to change your furnace filter.

2. Test the Thermostat Before You Really Need the Heat

Do not wait for the coldest day of the month to find out that something is not responding properly.

Set your thermostat to heating mode and raise the set temperature enough to call for heat. Pay attention to whether the furnace starts normally and whether warm air begins reaching the rooms in your home.

If the furnace does not start, repeatedly switches on and off, or behaves noticeably differently from last season, consider having the system checked.

3. Make Sure Supply Vents and Return Grilles Are Clear

Furniture, rugs, boxes and other household items can unintentionally block vents and return-air grilles.

Walk through your home and make sure airflow paths are open.

Natural Resources Canada recommends keeping return-air grilles and warm-air vents clean and unobstructed as part of normal heating-system maintenance.

4. Listen for Anything Unusual

You know the normal sounds of your home better than anyone.

When the furnace starts for the season, listen for new rattling, banging, grinding, squealing or other sounds that were not there before.

A new sound does not automatically mean that you have a serious furnace problem, but it is worth mentioning when you book your tune-up.

5. Look Around the Furnace

You do not need to open the furnace or attempt repairs yourself.

Simply look around the equipment and make sure the area is accessible and clear.

If you notice water where there normally is none, damaged venting, loose components or something that simply does not look right, leave technical diagnosis to a qualified HVAC professional.

6. Check Your Carbon Monoxide Alarms

If your home uses fuel-burning equipment, carbon monoxide safety deserves attention before heating season.

Health Canada identifies furnaces as a potential source of carbon monoxide and recommends maintaining fuel-burning appliances and having them professionally inspected regularly.

Make sure you have properly installed, certified carbon monoxide alarms and follow the manufacturer’s instructions for testing and replacement.

If a carbon monoxide alarm sounds, Health Canada advises leaving the building immediately and calling 9-1-1.

7. Book Your Furnace Tune-Up Before the Heating Season Gets Busy

There is a practical advantage to scheduling early.

When the first stretch of cold weather arrives, many homeowners turn on their furnaces at the same time. That is also when previously unnoticed heating problems tend to become much more urgent.

Booking your $79 furnace tune-up in fall gives you a chance to deal with your heating system before you are completely dependent on it.


Furnace Tune-Up vs. Furnace Repair: What Do You Need?

A tune-up is best suited to preventative care and seasonal preparation.

If your furnace is currently operating normally and you want to prepare it for winter, the $79 furnace tune-up is a sensible place to start.

A repair visit may be more appropriate if your furnace already has an active problem—for example, if it is not producing heat, repeatedly shutting down, failing to start or showing another obvious malfunction. In that case, learn more about Don’s furnace repair services and the common heating problems our technicians can diagnose and repair.


Can You Maintain Your Furnace Yourself?

There are some useful furnace-maintenance tasks homeowners can safely handle.

Changing the appropriate filter, keeping vents unobstructed, checking thermostat settings and keeping the area around the furnace clear are good examples.

Technical servicing is different.

Components associated with combustion, gas pressure, electrical systems, heat exchangers and safety controls should be evaluated by trained professionals rather than treated as DIY maintenance projects.

Health Canada recommends having furnaces and other fuel-burning appliances maintained and routinely inspected by professionals, particularly because proper maintenance also plays a role in reducing the risk of carbon monoxide exposure.


What If Your Furnace Is Older?

An older furnace does not automatically need to be replaced simply because of its age.

Condition, maintenance history, efficiency, repair history and overall performance all matter.

A seasonal check can also be an opportunity to ask questions about how your existing equipment is performing.

If you are starting to experience frequent furnace repairs, inconsistent heating or other recurring problems, you can also explore Don’s furnace installation, replacement and repair services.


Don’t Forget the Filter After Your Tune-Up

Preparing your furnace for winter is not a one-day task.

Your filter continues collecting particles throughout the heating season, so remember to check it periodically and replace or clean it according to the filter and equipment manufacturer’s recommendations.

A clean filter supports proper airflow and is one of the easiest HVAC maintenance tasks homeowners can manage themselves.

When is the best time to schedule a furnace tune-up?

Fall is an excellent time to have your heating system checked because you can address potential concerns before your furnace is needed every day. Natural Resources Canada also recommends pre-season heating-system check-ups.

Does my furnace need a tune-up if it seems to be working normally?

A furnace does not need to be broken for a seasonal check to be useful. Preventative maintenance allows the system to be examined before the period of highest heating demand and gives you an opportunity to identify potential concerns early.

Can I do a furnace tune-up myself?

Homeowners can handle basic tasks such as checking the filter, keeping vents clear and checking thermostat settings. Technical furnace inspection and servicing should be handled by a qualified professional.

How often should I change my furnace filter?

There is no single schedule that works for every furnace and household. Check your furnace and filter manufacturer’s recommendations and inspect the filter regularly. Natural Resources Canada recommends cleaning or replacing filters regularly and notes that filters in forced-air systems may need attention approximately every three months or whenever they become loaded.

What should I do if my carbon monoxide alarm goes off?

Leave the building immediately and call 9-1-1. Do not re-enter until it is safe to do so. Follow guidance from your local emergency services and Health Canada.
