Your Home is Unique. So Are Your Heating Needs.Trane furnace

Our customers often tell us that they love the peace of mind they get from our guarantee. We’re often asked how we can make this offer.

The answer is simple: we take the time to make sure you get the right furnace in the first place.

It all starts when one of our friendly heating consultant visits your home. We’ll discuss the best heating options, whether to install a furnace vs. a boiler. We take measurements and do an in-depth assessment of your home’s insulation quality and unique natural heating and humidity variations. This gives us what we need to do detailed heat loss/gain calculations. Our heating consultants make sure they offer the right size of furnace, because a furnace that is too large is almost as bad as one that is too small (a furnace that’s too powerful will cycle on and off more often, and will not only wear out sooner but will waste energy too).

As every home is unique, so is every family. Some families are on a tight budget, which makes upfront cost a priority. Others want long-term savings that a more energy-efficient furnace will bring. Lots of people may have concerns like noise level or more exacting standards when it comes to temperature variations.

Once we know what you want and what your house needs, we offer our recommendations for your new furnace. Our 30-day price guarantee means there is no pressure to buy right away – you have a full month to make your decision.

Brands We Know and Trust

Part of making sure you get the right furnace is offering brands with proven reliability for the tough Ottawa climate. We carry a wide range of Carrier and Lennox furnaces that includes different features and energy efficiency levels, so there’s something for every budget:

Comfortmaker furnace G96CTNIs It Time To Replace My Furnace?

If you are reading this furnace guide, chances are you have an old furnace that wastes energy, and you might be wondering if it is time to repair vs. replace your furnace. Here are a few clues that will help you decide if a new furnace is needed:

  • Your furnace lasts longer than 15 years old
  • Your furnace needs frequent repairs
  • Your utility bills have risen to unreasonable rates
  • An important part has failed (for example, the ignition control module)
  • Your home requires more heat than your furnace can produce
  • Your furnace makes loud noises

There are many reasons furnace replacement is needed, so don’t hesitate to get an expert opinion. Consult with an Ottawa furnace installation expert to learn more about the options available for your unique situation. The same goes if you just simply need a furnace repair in Ottawa.

How Do Furnaces Work?

Natural gas furnaces, oil furnaces, and propane furnaces all utilize fuel to operate. The type of furnace you use highly depends on the fuel source available to you.

Many Canadian homeowners have a gas furnace but don’t understand how it works. So here’s how this familiar appliance functions:

  • A thermostat sends a message to the furnace when heat is needed.
  • A control board inside the furnace activates key components, including a draft fan and a gas control valve.
  • An ignitor (or pilot light) lights gas-fueled burners inside a combustion chamber.
  • The heat from the combustion rises into a heat exchanger.
  • Air is warmed as it passes over hot metal coils.
  • A blower moves the warm air into ducts that distribute the heat to your home.
  • A vent system expels toxic combustion by-products through a flue pipe.
  • When the desired temperature is reached, the thermostat directs the furnace to close the gas valve, shutting off the appliance.
  • The process starts again when the temperature drops too low (or someone turns up the thermostat).

Electric furnaces are also an option. Instead of a combustion chamber, electric models have a compartment containing electric coils that become hot and warm the air. It’s important to note that while it may cost less to purchase an electric furnace, monthly utility bills are often higher due to electrical consumption, unless used in combination with a heat pump.

Some furnaces feature an additional accessory called a furnace humidifier. This extension connects directly to the heating system and combats the dry heat created by the furnace. As the air leaves the furnace, it flows past a humidifier and picks up moisture before being distributed through your home.

Are There Other Heating Options?

If you are looking for a new heating system, there are alternatives to using a furnace. Great options include:

Heat Pumps: Heat pumps are unique for many reasons. First, they serve two purposes—a heat pump is a home heating and cooling system. Second, they don’t create heat but rather move it around. How? Most absorb heat energy from outside air (even cold Canadian air) and transfer it to the air inside your home. During the summertime, they function as air conditioners.

A heat recovery ventilator can be added to enhance a heat pump and improve air quality. It’s an air exchanger that recovers heat from existing indoor air and transfers it to incoming fresh air.

Boilers: Rather than heating and blowing air throughout your home, a boiler uses a fuel source, like natural gas, to heat a liquid. It then pumps the hot liquid through a hydronic heating system, such as radiant floors or radiators. A boiler can also be used as your home’s hot water heater. Learn about the difference between furnaces and boilers.

What Are the Types of Furnace Stages?

While researching a new natural gas furnace, you may have come across the terms single-stage, multi-stage and modulating. Here’s an overview of what these stages are:

Single-Stage Heat

Older furnaces are commonly single-stage. It is an all-or-nothing approach; the gas valve is on, or it is off. As a result, when the appliance runs, it does so at full blast, cycling on and off frequently as the temperature in your house changes.

Multi-Stage Heat

In contrast, the gas valve inside multi-stage furnaces can open to varying degrees depending on how much heat needs to be generated. As a result, less fuel is used on milder days. Multi-stage units are also able to maintain a more constant even temperature in your home, and are considerably quieter than single-stage furnaces.

Modulating Heat

A modulating furnace adapts even more precisely to your home’s heating needs. Its burner regulates the amount of fuel burned to keep a very consistent temperature.

Are Furnaces Energy-Efficient?

Yes, a newer model is commonly a more efficient system. Older furnaces are less so.Energy Star products

When you are buying a new furnace, shop for ENERGY STAR-certified high-efficiency furnaces. These models will have an annual fuel utilization efficiency (AFUE) rating above 90%. (Gas furnaces made in the 1970s typically had ratings closer to 65%!)

In Canada, this information can be found on the EnerGuide label. A higher AFUE efficiency rating equates to more energy savings. (Note: A high rating does impact furnace cost. These models may have a higher price, but they more than makeup for it by significantly lowering your energy costs and reducing your carbon footprint.)

Does Furnace Sizing Matter?

Yes, it is critical to purchase the correct size for your home before having a furnace installed. Why? Because furnaces that are too large or too small don’t function correctly. They cycle on and off frequently, wear out quicker, and require repairs often. Enlist the help of a licensed HVAC contractor who will perform calculations based on many factors (such as heat loss, home construction, insulation occupancy, and climate) to determine the optimal size furnace for your residence.

Do You Need Furnace Maintenance?

Having a qualified HVAC technician perform annual furnace maintenance is not expensive, and well worth your money. When you properly maintain your heating equipment, you will keep your furnace working at peak efficiency and avoid unexpected repair costs.

A professional will examine the system, clear debris, check for damaged parts (like sensors and gas lines), change the furnace filter, inspect the air filtration system for proper airflow, and more. Most importantly, they will answer any furnace-related questions you have.

There are also some things you can do to ensure your furnace operates safely and efficiently. First, regularly check that your carbon monoxide detectors are working properly. All gas-burning appliances produce CO, and leaks can lead to serious health hazards. Next, change the air filter every month or two. They are cheap, easy to replace, and the most common fixable issue that causes service calls.

Choose A Reliable Furnace Brand

When searching for the right furnace, choose a brand dedicated to both quality and energy efficiency. You can’t go wrong with either of these brands; you’ll reduce your heating bills and stay warm and toasty all season long.
