Don't risk enduring a moment of our Ontario winters without heating. Furnaces usually last approximately 15-20 years. If yours is approaching retirement age, consider a replacement or upgrade; don't wait until you need an emergency furnace repair.

If your furnace is getting older, it may experience some of these common problems:


Dirty or Clogged Furnace Filter
A dirty air filter blocks the air flow and will make your furnace work harder than it needs to. If your furnace filter is clogged, it may force your unit to overheat and shut down. Fortunately, replacing a furnace filter is a quick and easy - just remove the old filter and replace it with a new filter..


Broken Thermostat

Your thermostat talks to your furnace and tells it when to turn on and off. If your house is excessively hot or cold or your furnace fails to turn off by itself, you may have a problem with your thermostat. Before calling a professional, ensure the thermostat has fresh batteries.


Malfunctioning Ignition Control

Your pilot light is a small flame that ignites the natural gas that heats the air in your home. If there's something wrong with the pilot light, your furnace won't be able to produce heat. Always call a pro for a gas furnace repair, as you need a qualified technician to do the job safely.


Inadequate Maintenance

Furnaces need annual cleaning and maintenance. Without proper care, things are more likely to wear down and break. A professional HVAC technician can clean, calibrate and lubricate the entire system to keep it running smoothly. A technician can also spot and make minor repairs before they turn into expensive ones.



There are times when a furnace repair is too costly, and it's better to replace it. Here are some signs it's time to replace your furnace:

  • Your furnace is more than 15 years old.

  • Your furnace needs regular, costly repairs no longer covered under warranty.

  • Your energy use is going up with no explanation. A furnace loses efficiency as it ages and works harder to heat your home.

  • The repair cost is at least 50 per cent of the cost of a new, high-efficiency furnace.

If it's time to replace your furnace, consider a new Carrier furnace from Aire One Heating & Cooling. We're an authorized Carrier dealer and carry high-efficiency models with annual fuel utilization efficiency (AFUE) ratings of more than 95%.

  • How often should I service my boiler?
    A minimum of once a year is recommended. Heating systems come on an average of 3-8 times per hour during the heating season, these numbers can change dramatically in different style of homes and with different thermostats, but this is a rule of thumb in our industry. There is a lot of wear and tear on the appliance and setting can go out of calibration. Also, it is a requirement by most manufacturers and home insurance companies.
  • Can I add new zones to my existing boiler heating system?
    It depends if the btu output of the radiators has reached the maximum btu output the boiler can support. Having a professional to come out and calculate is your best bet.
  • How will I know if the boiler I select will work properly for my home?
    Each room will have a radiator and every radiator has a specific btu output . We calculate the total of the radiator btu outputs, match that with a heat loss/heat gain calculation for the home and that is how we size a boiler system for your home.
  • How does a boiler work to heat my home?
    A boiler is a device that heats water and then distributes the hot water throughout your home to warm the indoor air. There are two main types of boilers: hot water boilers and steam boilers. Hot water boilers heat water to a temperature of about 82 C. The hot water is then circulated through a system of pipes and radiators throughout the home. The radiators give off heat to the surrounding air, which warms the home. Steam boilers heat water to a temperature of about 100 C, which is the boiling point of water. The steam is then distributed through a system of pipes and radiators throughout the home. The steam condenses back to water on the radiators, which gives off heat to the surrounding air, warming the home. In both hot water and steam boilers, the water in the pipes cools and returns to the boiler after heating the interior spaces. The water is then reheated and recirculated throughout the home. Some boiler models also double as a water heater, eliminating the need for a separate water heater unit. The efficiency of a boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating is a percentage of the fuel that’s used to heat the water that heats the home. The higher the AFUE rating, the more efficient the boiler. Boilers with medium levels of efficiency have ratings of 90 to 93 per cent.
  • What is the average lifespan of a residential boiler?
    The typical residential boiler can last between 15 and 20 years. You can find the year your boiler was manufactured by checking the unit’s rating plate. You can also call the manufacturer and give them the unit’s serial number to find out how old your boiler is. If your boiler unit is more than 15 years old, you should consider replacing it with a new boiler, high-efficiency gas furnace or heat pump.
  • Are there any government rebates available for my boiler upgrade?
    Unfortunately, Ontario homeowners in the Tri-Cities area wanting to invest in a new boiler system for their homes aren’t eligible for rebates under the Home Efficiency Rebate Plus (HER+) program. Heat pumps are the only home heating system covered under HER+, whereby homeowners can get more than $10,000 in rebates on a heat pump installation. This program combines the Enbridge Gas rebate program and the Canada Greener Homes Grant.

Explained What He Was Doing Along the Way

The service tech arrived early from the time slot I was given. I really liked that a text was sent to my phone telling me he was on his way. He did the annual tune-up and maintenance checks, and explained to me what he has doing (and why) along the way -- first on the furnace then the AC unit.
