The Homeowner's Furnace Guide
Table of Contents
We are proud to call Calgary home. But when the temperature drops, “home” certainly isn’t a place you want to be without a good furnace. Our winters are cold, dry, unpredictable – and yes, long too. This makes it all the more important to have a well-maintained furnace you can count on.
Unfortunately, like any appliance, furnaces often require repairs – or even replacement.
We’d like to share a few simple maintenance and repair procedures that most homeowners can do themselves. At the same time, we will explain common repair and servicing work that may require the expertise of a trained professional. Is your furnace on its last legs? If so, an HVAC specialist will be required to install a new unit – and can even recommend the right model.
If there is one piece of wisdom we can leave you with, it is to find a trusted HVAC specialist, keep their phone number handy and set up appointments regularly. It’s the easiest way to ensure your furnace is well-maintained, and your family is always toasty warm.
1. How your furnace works
2. Why get a furnace tune-up
A professional furnace tune-up and inspection is part of the recommended maintenance schedule for a furnace. It helps detect and prevent furnace problems before they cause significant damage or cost you money. A regular tune-up will also provide peace of mind, knowing your family will be safe and warm.
Advanpro’s comprehensive furnace tune-up includes inspecting, testing, and cleaning all sensors, burners, exhaust, wiring, and motor functionality. We also test the switches and circuits and check the filters, gas pressure, and other mechanical components. We want to make sure all the moving parts and electrical connections are working well, and won’t cause issues in the future. When in doubt, book your furnace tune-up.

Choosing a furnace
The vast majority of homes in Calgary are heated by natural gas furnaces. There are a few things to consider when selecting the right furnace for your home, including the size of your home, number of floors, the number of furnaces you have, the age of your home, and the layout of your home. These factors taken together will help determine the type of furnace best suited to meet your needs. Larger homes need bigger furnaces. Furnaces are sized by their BTU Input rating, and the higher the BTU Input the larger the furnace, which usually costs more to install. It may be tempting to purchase a smaller furnace to save money, but if a furnace is too small, it’ll have to work harder and won’t be able to keep the house warm.
Furnaces generally range from 45,000 BTU up to 135,000 BTU. A 135,000 BTU furnace will typically be about 25% higher in cost than a 45,000 BTU model from the same manufacturer.
Today, nearly all furnaces are high-efficiency models, which are popular because they reduce energy consumption. Designed to maximize every last tiny bit of heat from natural gas combustion, they have AFUE ratings from 90 percent to as high as 99 percent and transfer anywhere from 14 to 50% percent more heat to your home than a standard furnace with the same volume of natural gas consumed. In Alberta, it is now mandated that all new furnaces must have an AFUE rating of 96%. Long story short, new high-efficiency furnaces use less energy to heat your home more evenly, leading to a more comfortable living environment and less energy consumed means cost savings.
Furnaces typically fall into three categories:
Single-stage furnace: Furnaces that blow for a period and shut-off when the target temperature is achieved. In Calgary, these can cost between $4,300-$5,500 (installed).
Two-stage furnace: A two-stage furnace runs at a lower speed and heat output when the weather is mild, and at higher speed and output when it starts getting colder. Benefits include: more consistent warm air distribution, quieter operation, less stopping and starting (for less wear and tear), and increased energy savings. Prices range from $5,000-$6,500 installed).
Modulating furnaces: These premium furnaces are designed to keep your home at a steady temperature at all times. The furnace quietly runs for longer stretches and consistently circulates warm air throughout the home—for more even temperature distribution and a more comfortable environment. While the warm air runs more or less continually, these furnaces are actually more efficient than single- or two-stage furnaces, using less energy overall. These can cost anywhere from $6,000-$7,500 (installed).
Like anything, you’re better off to choose a reputable and reliable name brand furnace backed by warranty. (Advanpro is proud to represent Lennox). The more energy-efficient your furnace, the more money you’ll keep in your pocket when the utility bills come due.
Getting a quote
It’s always advisable to get more than one quote. Make sure quotes include all services and fees upfront, including disposal of the old unit, permitting, CO detectors, etc. If you want additional options (such as a humidifier, UV Light, or upgraded Air Quality Filtration System), get that priced at the same time. It is less expensive to have these systems installed at the same time as your furnace installation instead of having them done after the fact.
If a price seems too good to be true, it probably is. There is value in engaging a reputable and experienced company like Advanpro. A fly-by-night, one-man operation will likely not be there to stand behind a labour warranty or service your furnace down the road.
5. Furnace installation
Installing a furnace is a job that must be done by (or an Apprentice at least overseen by) a Journeyman Gas Fitter, Plumber, or Sheet Metal Worker. It requires a municipal permit, inspection, and approval. As you’re are dealing with Natural Gas and Electricity it’s not recommended to mess around with expensive and potentially dangerous mechanical systems in your home. As with any major purchase it is recommended to do your homework. You should buy your furnace from a trusted and established HVAC Company, who will also do the installation, and provide a solid warranty on their work.
6. Humidifiers and optional equipment
Humidifiers for good health
Alberta’s mountains provide plenty of outdoor fun, but they also leave us with some of the deepest and coldest winters in North America. Calgary is also incredibly dry, which can affect our skin, health, and the health of our home.
One thing that can make life in Calgary more comfortable is a humidifier. Whole-house humidifiers are attached to your furnace, which introduces moisture into the air circulating through the furnace, and in turn, moist air is distributed through your ductwork and into your home. This invisible moisture helps with everything from dry skin and nose bleeds to sinus issues and respiratory irritation. By investing in a humidifier, you can raise the humidity to an ideal level and keep everyone healthy and happy. Additionally, keeping your homes’ humidity consistent year-round helps prevent warping and splitting of wood furniture and hardwood floors.
7. Simple do-it-yourself maintenance
The typical sizes for a furnace filter are 16″ x 20″, 20″ x 25″, and 16″ x 25″. The size of your filter will be stamped on your existing furnace filter. It may be located on the filter rack you slide your furnace filter into on the side of your filter cabinet. The filter must fit snuggly in your furnace, as a good fit prevents unfiltered air from seeping around the edges of the filter. A filter’s thickness can range from 1″ to 5″, depending on the furnace make and model. As a general rule of thumb, a thicker furnace filter will last longer and do a better job of filtering the air in your home.
Replacement filters can be purchased at most hardware stores or online through Amazon and other retailers. If you are not sure which size you need, check the filter currently in your furnace.
Filters typically need to be replaced every 1-3 months depending on the type of filter you’re using. If you notice the furnace filter’s surface is gray and covered in buildup, you should go ahead and change it. Other signs you may need to change your filter are more dust in the home or longer heating and cooling cycles.
If your thermostat is battery operated and is not working, the batteries may be dead. Many programmable thermostats feature a flashing “low battery” icon on their control screen. If you see a “low battery” warning, put in fresh batteries.
The thermostat is one household electronic that has seen many upgrades over the years. Today there are many options, including manual, programmable and smart ones.
Here are some things to consider if you’re replacing your thermostat:
These traditional models getting replaced with all the smart thermostat technology available. Manual thermostats may be old school, but they work and are still recommended by most heating and cooling professionals. One consideration is that manual thermostats are not as precise when it comes to temperature accuracy, which means it may be difficult to keep the temperature consistent and exactly where you want it. They also won’t have humidity control or the ability to run your circulation fan.
A second option is programmable thermostats, which offer customization and energy savings. You can schedule and set your temperature and no longer have to adjust the temperature manually as the day heats up and cools down. With these added features, programmable thermostats will cost more than manual ones. You’ll also need to speak with a professional about which programmable thermostat is compatible with your system.
Smart thermostats are the top choice for tech-savvy homeowners who like to schedule and control the temperature settings throughout the day. Beyond the temperature controls, these toys can provide energy reports, run times, and notify you if your air filter needs replacing. They can also control humidity and run your furnace blower motor when the furnace is not running to ensure the air in your home is fresh and constantly being filtered. They also allow you to control your home’s temperature remotely when not at home and can notify you if your home’s temperature is dropping below its set point.
If you plan on replacing your thermostat, it’s always good to talk to a professional who can advise you based on your home, and your current system. There’s no sense spending money on something that isn’t going to help you.
