HVAC Contractors in St. Catharines

While removal of the old HVAC unit is covered as part of this service, disposal is not covered and must be arranged in advance of your installation.

Please note that additional charges may apply for disposal of your old HVAC unit.

If you determine a major fix is necessary, review your warranty coverage first before investing in repairs or a replacement.

It may be necessary to replace your gas furnace if you notice the following signs:

• Your gas furnace is taking too long to ignite.
• Fails repeatedly to deliver enough heat even at maximum settings.
• Exterior surfaces show signs of corrosion.
• Emits unpleasant odors when operating such as rotten eggs.
• Experiences frequent pilot light failures.

For a central air conditioner or heat pump, look for:

• Ineffective heating or cooling.
• Excessive noise.
• Buildup of moisture or humidity.
• Longer run times or foul “burning” smells.

All the above are likely signs you need to replace your air conditioner or heat pump system.

• An aging furnace may pose a serious health risk to anyone living in your home:
• If the heat exchanger or flue pipes have cracked, it could be leaking carbon monoxide.
• If your HVAC system is more than 10 years old, the cost of repairing or replacing a major component may not be worth it compared to investing in a new, more efficient unit.

With annual maintenance, an HVAC system should last for many years. Still, the efficiency of an HVAC unit can drop over time, meaning your utility bills will increase.

High-efficiency HVAC systems are designed to use less energy to heat or cool your home. In other words, they consume less energy to do the same job as a lower-efficiency unit.

For example, a high-efficiency gas furnace rated at 96 per cent AFUE (Annual Fuel Utilization Efficiency) is designed to deliver 96 per cent of the heat it produces to your home and lose just 4 per cent. An older system, at 80 per cent AFUE, loses 20 per cent.

Upgrading to a system that wastes less energy means you’re consuming less energy and, most likely, saving money.

“BTU” stands for “British Thermal Unit”, which is used to measure thermal energy output. It takes 1 BTU to change the temperature of a pound of water at sea level by 1-degree Fahrenheit.

BTU ratings on HVAC systems reflect overall output. The number of BTUs you need depends on the size of the space to be heated or cooled.

Choosing between a gas furnace and central heat pump mainly depends on whether your home is set up for gas or electric heating.

Heat pumps are sometimes preferred over air conditioners because they provide heating in addition to cooling.

Ductless air conditioners and heat pumps are typically used for individual rooms and small spaces, while central air conditioners and central heat pumps are designed for a whole home.

The correct-sized HVAC unit depends on the square footage of your home, as well as the number of rooms; during your free, in-home consultation, a Home Depot Installer will help you find the right-sized HVAC system for your home.

Remember, bigger is not necessarily better. An HVAC system that is too large for your home may not regulate temperature or humidity as efficiently or effectively as a correctly sized one. A mismatched system may also need repairs sooner.
