Heating & Air Conditioning


In Southern Ontario, having reliable heating system is essential. For a homeowner, a furnace break down is a stressful situation, and we understand the sense of urgency that it can create.  Don’t wait for an emergency – Get in touch with us if you notice any of the following warning signs:

  • A rising energy bill
  • Frequent repairs and replacement of parts
  • Different temperatures in different rooms

Our professional technicians will come in and assess the situation.

Furnaces and heating systems come in many shapes, sizes, and functions. Your furnace will quickly become the most important appliance in the house! Let us know your home’s needs, what fuel sources are available, and how much space you need to heat so we can recommend the best possible model for you.

No matter what system your household runs, a furnace should always do the same thing:  Keep you and your family warm and comfortable.



In addition to the frigid winters, Southern Ontario often endures some blistering hot summers. A cooling system break down can quickly make your home uncomfortable or affect your workplace productivity. SB Mechanical has been providing HVAC services for over 27 years. If you’re in need of air conditioner services, we have the technicians to help

Unlike heating systems, an air conditioning system is much more complex. Instead of using energy to create heat, it uses it to remove heat. Air conditioning absorbs and releases heat from inside and transfers it outdoors through a compressor located just outside the house.

Air conditioners of all kinds requires a great amount of electricity to operate, especially when outside temps are at their warmest! Want to save some money on your electricity bill? Consider making the switch to an energy efficient model. Whatever your cooling needs, we can provide a wide variety of air conditioner solutions. Our technicians can help you with routine air quality inspections and replacement of your old cooling systems.

What should you watch out for?

  • Warm air and poor or weak airflow
  • Inadequate cooling and circulation
  • Strange noises
  • Unusually high indoor humidity level

Air conditioning units generally last for around 10 years. Our technicians can help with repairs, replacements, and efficiency upgrades. Don’t risk melting when the summer temperature starts to rise.


What can you expect during a routine tune-up?

Our technicians will check important components of your heating system during maintenance. Some of this work includes:

  • Inspecting and cleaning gas burners. Our techs will also examine your heat exchanger for cracks. These cracks can cause life-threatening carbon monoxide leaks or a fire.
  • Observing airflow and blower operation to ensure your furnace is operating correctly.
  • Checking the gas valve. This makes sure the precise fuel supply pressure is sent to the furnace, allowing it to heat safely.
  • Perform a combustion analysis
  • Clean blower wheel, if required
  • Examining electrical-powered parts for damage or corrosion.
  • If you have an older furnace, we will also check the pilot light

Cooling Services include:

  • Tightening electrical connections. This ensures your system is running safely.
  • Lubricating parts. When your system lacks lubrication, rubbing from moving parts can cause it to break down more often or more quickly.
  • Cleaning the condensate drain line. Cleaning this line takes care of any mold and clogs, which can cause leaks.
  • Cleaning the condenser coil and evaporator coil. These coils get dirty over time, decreasing airflow and the capacity to absorb heat.
  • Straightening coil fins. Aluminum fins on the coils can bend and decrease airflow.
  • Examining system controls. This makes sure your system is starting, running and shutting down correctly.
  • Check temperature and pressure of the refrigerant

What should you be doing between tune-ups? Here are two things you can do yourself to ensure consistent operation.

  • Change the air filter. We recommend replacing your air filter every 3 months, inspect it monthly. The easiest way to do this is to remove it and hold it up to the light. This helps yours system operate more efficiently. You may have to replace your filter more often if you have pets or someone in your household has allergies.
  • Remove debris. Leaves, dirt and grass clippings can build up on the outside of your system. This can limit capacity and reduce airflow. Shrubs and plants near the unit should be kept trimmed back. Avoid blowing grass clippings against the unit.


A Wi-Fi or smart thermostat is more clever than a programmable thermostat. A smart thermostat figures out your behavior and knows when you leave the house. This permits it to adjust comfort/temperatures accordingly.

Apps give you the ability to watch your home while you’re away and fine-tune temperature settings from almost anywhere. A bonus – a smart thermostat displays your energy use in real time. A smart thermostat can be used with most any HVAC system. Some are even compatible with your smart speaker, allowing you to adjust the thermostat with voice commands. Others have room sensors, which can assist in keeping temperatures consistent.

A smart thermostat may be a solution for you if…

  1. Your energy bills keep increasing.
  2. You are always forgetting to adjust the thermostat.
  3. Your calendar is jam-packed—and constantly changes.
  4. You’re having trouble regulating your home’s temperature.
  5. You want to reduce energy waste.
