Other Factors Affecting Furnace Installation Cost
Size and Capacity (BTU)
Depending on how big your home is we will recommend a unit that will work out for your needs in both upfront cost and overall energy savings.
Existing Ductwork
There is some labour cost that needs to be considered and is usually unique to each home. Our HVAC technicians find the best way of retrofitting your new furnace connections to your existing ductwork to save on cost. New builds often require extensive duct installation and can cost substantially more.
Long Term Planning
If you plan to live in your home for many years you may want to consider going with a more efficient gas furnace model. Over time premium furnaces will reap the reward of potential gas usage and maintenance/repair savings. The highest consumer-rated models are made by Trane and American Standard. Through reports from 2005 – 2021, these units had the least breakdowns and required minimal maintenance costs.

Yearly Natural Gas Costs and Furnace Maintenance
Fortis BC estimates an average 2,300 sq ft home costs $815 annually for Natural Gas usage. This number varies depending on your home’s square footage, insulation, heat loss, and personal preferences. At Techno Gas we offer furnace tune-ups and inspections once a year at an affordable $139 annually.

Additional Furnace Features
With modern technology HVAC systems and controls have become much more advanced. Let’s look into some additional parts that your furnace system may need:

Thermostats
The thermostat is the main way to control your heating system temperature output. Thermostat cost and installation starts at $250 for basic models and can range up to $500 for premium models.

Zoning Control
A major upgrade to your gas furnace system is to add multiple smart thermostat paired with automatic dampers that regulate the airflow into each room (zone) of your house. This way you get customized confort for every part of your home. In genaral larger homes can make more use of a zone control system as there are often issues evenly heating the air over greater distances. The costs depend on your current ducting system but this upgrade can range from $1500 to $2500 in addition to a your gas furnace installation.

Variable Speed Blowers
Variable-speed blowers excel in providing a quieter and more consistent airflow, adjusting their speed to match your heating needs. This not only minimizes noise levels but also prevents uncomfortable temperature fluctuations and drafts, ensuring a more pleasant and stable indoor environment. Many of the modern furnace models have this featyre included for $200-$500 more than entry level units.

So if you have an older natural gas model you will likely qualify to upgrade to an energy star rated model. Let us help you choose a new furnace and fill out the rebate paperwork so you can save on your installation.
Cheaper to Repair or Replace?
Despite the promise of high efficiency and cost savings on your monthly natural gas bill, it is often cheaper to repair an old furnace than fully replace it. The only instance would be when one of the unit’s main parts breaks like the heat exchanger or control module. These parts are often so expensive that it’s risky to install them in a furnace that is older than 15 years as it more liable to break again. Before you contact a certified heating contractor like us check to see if there is a small issue that can be fixed in our guide below.
Common Furnace Problems and Their Solutions
If your furnace isn’t producing enough heat, it could be due to a clogged air filter. A dirty filter restricts airflow, leading to reduced heat output. Solution: Check the air filter and replace it if necessary. Regularly changing or cleaning the filter can prevent this issue.
If your furnace isn’t generating any heat, several factors could be responsible. First, check the thermostat settings to ensure they’re properly configured. If the thermostat is set correctly, the issue may lie with the power supply. Solution: Check the circuit breaker or fuse box to ensure the furnace is receiving power. If the problem persists, contact a professional HVAC technician for further inspection.
If the blower fan keeps running even when the heating cycle is complete, it could indicate a faulty limit switch. The limit switch is responsible for turning the blower off once the desired temperature is reached. Solution: Replace the limit switch to resolve the issue. It’s recommended to seek assistance from an HVAC technician for this repair.
Strange noises such as banging, squealing, or rattling coming from your furnace can be alarming. These noises often indicate loose or damaged components within the system. Solution: Inspect the furnace for any loose or broken parts. Tighten or replace them as needed. If you’re unsure about the source of the noise, it’s best to consult a professional technician to avoid further damage.
If you have an older furnace with a pilot light, it may occasionally go out, preventing the furnace from heating. Solution: Relight the pilot light according to the manufacturer’s instructions. If the pilot light still won’t stay lit, it could be due to a faulty thermocouple. In such cases, it’s advisable to have a qualified technician replace the thermocouple.
Short cycling occurs when the furnace frequently turns on and off in rapid succession. It can strain the system, increase energy consumption, and impact overall performance. Solution: Check the air filter for clogs and ensure proper airflow. If the problem persists, it could be due to a malfunctioning thermostat, improper furnace size, or an issue with the heat exchanger. Contact an HVAC professional to diagnose and address the underlying cause.
If you notice significant temperature variations between different rooms or areas in your home, it could indicate an issue with the furnace’s airflow or ductwork. Solution: Inspect the air registers and ducts for any blockages or leaks. Ensure they are clean and properly sealed. If the problem persists, it’s recommended to consult an HVAC technician for a comprehensive evaluation and solution.
