Ashton Technicians


Whether you need Air Conditioner, Furnace or other HVAC Service and Repairs in Oshawa, Whitby, Bowmanville, Courtice and beyond- here are some helpful hints from our technicians to save yourself from unnecessary costs and service calls. Try these tips before calling- it might save you some money!

-Ensure the batteries to your thermostat are fully charged and working well and that your thermostat is turned on, operational and set to the temperature setting you desire like ‘heat’ or ‘cool’. We know- it sounds like basic advice, but you’d be surprised how often we attend to service calls that simply require us to change batteries!

-If your fireplace isn’t working, check the batteries in the remote, and in some units, you’l also need to check the batteries in the  internal remote sensor located inside your fireplace.

If you can’t remember the last time you changed the filter in your furnace, you probably need to change it!

Most people don’t realize that no matter what season it is, your filter in your furnace filters all the air that moves through your home, whether it’s cold or hot.  If air is moving through your home- it’s being filtered!

When your filter gets dirty it makes it harder for the air to flow through the system, making it work harder than it needs to. Sometimes your filter can get so dirty that the system will stop working completely.  Check and change your filter if it looks dirty before calling for any service calls.

Your filter should be changed every 6-12 months depending on the level of use your home gets and things like kids, pets, candles, smoking etc. It should also be changed whenever any home construction or renovations have been done. 

A lot of people don’t realize your furnace is typically wired to a switch, and sometimes it can just look like a light switch on the wall or ceiling of your furnace room. Occasionally this can get switched off and cause your appliance not to turn on. Ensure your switch isn’t turned off before calling for service. 

Frequently Asked Questions

We get asked this question a lot, and the truth is, sometimes it can be hard to tell. But there are a few reasons you should start considering a new unit. The main one being: If your unit is more than 10 years old you’ll definitely want to start creating a long term plan to save/prepare for the purchase of a new appliance in the future. During a Maintenance, inspection and cleaning your technician should be able to provide you with a better idea of how much more time you can get out of your unit.

Some other reasons you may want to consider a new unit include:
– If you’ve noticed a reduction in efficiency or it is a low efficiency older model
– If you have recurring breakdowns or issues or need multiple service calls in a season
– If you need costly repairs for a major part and don’t have a maintenance or protection plan in place to cover them

The bottom line is, it’s the law. Only certified gas technicians can work on a gas appliance. We’ve spent our lives receiving technical and appliance-specific training and have years of experience dealing with every issue you could run in to. We can diagnose the problem quickly and properly without you wasting your time, money or patience. Ensure the efficient operation of your furnace and most importantly- keep your family and pets safe by leaving the gas appliance work up to the professionals.

We recommend getting your gas appliances checked annually. Not only will this ensure your appliance warranty stays valid if you have a newer appliance, but it will ensure your appliance is running safely and efficiently. Any potential issues will be spotted by your technician who can then discuss with you if you need to make any repairs to prevent breakdowns or further issues or if any changes to maintenance are required.

If you’re looking for a way to make your appliance maintenance hassle-free and save a bit of money, we recommend considering a maintenance or protection plan. Our Ashton Advantage Plans come in a variety of price points with different levels of coverage to suit your needs and budget.

This could be for a number of reasons, some of which include a dirty filter, dead thermostat batteries/ incorrect thermostat settings, or could be due to a broken or malfunctioning part. If you’ve checked your filter and thermostat and everything seems to be fine, give us a call.

That depends on a number of factors. If your air conditioner is more than 10 years old, and it requires a costly part like a compressor or motor or if you have frequent service calls it would likely be more economical to replace, versus continuing to repair. If your unit is less than 10 years old and otherwise in good shape, and you need a more commonly broken part like a contactor or capacitor then fixing it is likely your best option.

The short answer is – not always. Some leaks depending on where the leak occurs are so costly to fix that it’s not economical to do so and the replacement of your appliance may be the better alternative. Also, it’s not legal in Canada for technicians to just ‘top up’ your refrigerant without determining and fixing the source of the leak.
