Replace your air filter

A dirty filter can mean an inefficient system.

Filters catch dust, hair and other debris in the air before they enter the blower fan in your furnace – subsequently improving your home’s air quality by preventing debris from recirculating.

Not replacing your furnace filter has a number of repercussions:

  • You run the risk of clogging your furnace. If this happens, your furnace can overheat/shut down.
  • Your furnace coil will get dirty
  • Problems with your heat exchanger

We recommend that you replace your filter every three months, or once annually in the case of a Mechanical Air Cleaner. You will have to change it more often under the following circumstances:

  • You have had construction work done in your home since your last filter replacement.
  • You have several pets living in your home.
  • You suffer from allergies.
  • You keep your windows and doors open throughout the summer.

Clear room around your furnace

The area around your furnace should ALWAYS be clear, particularly of flammable objects.

That’s why you’ll want to ensure any items that found a place beside your furnace are moved out of the way before the winter starts. You’ll also want to ensure that all of your vents are clear from obstructions in order to maintain proper airflow.

A little maintenance goes a long way…

Scheduling an annual A1 Check, Clean & Safety Inspection for your furnace can save you the headache of an unexpected system breakdown on a cold winter’s night.

7 warning signs that you need to replace your furnace

It may not feel like it right now, but winter is on its way. The question is, will your furnace be ready?

Here are 7 warning signs that your furnace may be in need of an upgrade:

  1. Your furnace is over 15 years old. Note: an older furnace also means older technology and as such, it will not be as energy efficient as a newer model.
  2. There are visible signs of rusting around your furnace.
  3. Your furnace is requiring more frequent repairs.
  4. Your energy bill is rising, despite the same amount of usage.
  5. Humidity problems have suddenly become more common in your home.
  6. Your furnace is a lot noisier than usual.
  7. The rooms in your home are not heating evenly.

Having a trained HVAC professional inspect your furnace will help you gauge whether or not it’s time to replace your system.

Note: Your air conditioner relies heavily on your furnace to cool your home during the summer months. That’s why furnace maintenance is a recommendation that applies all year round.



Here’s why your high-efficiency furnace isn’t working after a large snowfall

Ensure your intake and exhaust pipes are clear of snow!

First off, you should find where the exhaust/intake pipes are connected to your furnace. These pipes will be non-metallic (likely plastic) and they will attach to your furnace and end on an exterior wall. Once you have located them, find where they lead outside and get your snow gear ready.

Once you’re all bundled up and have your shovel ready, find where you think the pipes lead to and start digging. You’ll want to clear all the snow around the area to ensure that you don’t have a continuing issue. Once done, check and see if there is anything clogging the pipe(s).

If your system is up and running again, you’ve saved yourself a service call, if not, you can always give us a call.



One major part of your indoor air quality is the humidity. Too much or too little moisture in the air affects your comfort, your family’s health and the condition of your home’s interior and furnishings. Ideal humidity is usually between 30% and 60%.

In the winter, Canadian climates can be very dry. A dry environment can lead to irritation of airborne health issues such as asthma, bronchitis, sinusitis and nosebleeds. Even if you don’t suffer from any of these ailments, dry air can cause skin and eye irritations.

The products below can help you solve these indoor air quality issues.



At A1, we recommend an Energy Recovery Ventilation unit (ERV) over a Heat Recovery Ventilation unit (HRV). While they generally perform the same duties, ERVs can control humidity levels more effectively and are functional all year long, while HRVs are only useful in the winter.

Exchanging stale air for fresh air without significant changes in temperature is the main objective for an ERV. The system uses air-to-air temperature control, which utilizes outgoing air to condition the incoming air.


Air Purification Systems

Air Purification Systems, such as the PureAir System, are used to attack:

  • Small breathable particles such as dust, dirt, pollen and allergens.
  • Dangerous particles such as airborne mould, spores, bacteria and viruses.
  • Unpleasant odours and potentially harmful chemical vapours.

Purification systems can offer some benefits that simple filtration can’t. The particles mentioned above would be combated, not just filtered out. By attacking these particles directly, you are able to remove a higher percentage of the pollutants from the air you breathe.



Remove the Cover

This is the simplest yet often the most overlooked task. Remove the cover from your air conditioner’s outdoor unit before starting up the system.

Clean the condenser coil

First, ensure that your air conditioner has the power shut off before doing any cleaning. Then you can clear the area surrounding the unit of any long weeds, shrubs or other obstructions.

Depending on the amount of dirt on your coil, you can usually clean it with water straight from your hose. If it’s extremely dirty and really restricting the airflow in your system, it’s best to call a service technician to clean it for you.

Change the air filter

Airflow is critical for performance, efficiency and comfort. Basic filters need to be replaced every three months. Mechanical filters need to be changed once per year.

But, there are certain exceptions of course:

  • You have had construction work done in your home since your last filter replacement
  • You have several pets living in your home
  • You suffer from allergies
  • You keep your windows and doors open throughout the summer

A clean filter catches allergens and other unwanted particles, while improving the airflow in your home.

A dirty filter can cause many problems in your system including:

  • Your air conditioner could freeze up and subsequently cause damage to your coil and other areas

  • If the coil freezes, the defrosting process could also damage your furnace since the coil sits directly above it


Check the circuit breaker

Reset the breaker associated with your air conditioner and run it for a short period of time. This will help ensure that there are no shorts in the system.


If the breaker trips when you do this, something may have happened over the course of the winter and you should schedule an appointment with a service technician to investigate.

A little maintenance goes a long way…

Scheduling an annual A1 Check, Clean & Safety Inspection for your air conditioner can save you the headache of an unexpected system breakdown.

A1 Cares.

Here’s what our customers have to say:

“Thank you, A1, for your brilliant SuperCare plan – it saved me hundreds of dollars. Just as the heat wave started rolling in our A/C decided to stop working. It wasn’t going to cool any longer. After A1’s mechanics did a leak test on the evaporator coil they quickly determined there was a leak. Without a SuperCare plan the coil repair would have been quite costly, but due to our small yearly investment we saved… Thank you so much.” – Candice

“We can’t say enough about A1 Air Conditioning & Heating. Every interaction has been stellar, on time, honest, friendly. I highly recommend this company. You guys ROCK!” – Elaine

“You really stepped up to the plate… You offered me a deal…installed the same week with a ten-year warranty. This action went well beyond what I expected. Your company will always be Number One…” – Harold
