Buying a new furnace isn’t something most homeowners do often — but when the time comes, it pays to be informed. A furnace is a long-term investment in comfort, efficiency and peace of mind, especially during Calgary’s cold winters.
Whether you’re finally replacing an old unit or planning ahead before the next cold snap, this furnace buying guide from Springs Servicing & Heating covers 10 important things to consider before making your final decision.
1. Repair vs Replace
Before buying a new furnace, it’s worth determining whether your current system truly needs replacement or whether a repair could keep it running reliably. If your furnace has been breaking down frequently, is very old or struggles to keep your home warm, replacement may be the better long-term investment.
An HVAC professional can assess your current system and make recommendations based on its condition, performance and your efficiency goals.
2. Different Types of Furnaces
Homeowners can choose between gas, electric, oil or propane furnaces. Each type has pros and cons, but sticking with the same fuel type as your current system can often keep installation costs lower and installation planning simpler.
If you’re wondering where to start: the best choice depends on your home’s existing setup, available energy source, budget and heating needs.
3. Consider the Features You Need
Furnaces today offer more than just heat. Look for optional features like variable-speed blowers, multi-stage operation and humidity control for better comfort and efficiency. A modern system with these upgrades can provide smoother, more consistent heating than older equipment.
4. Proper Size and Capacity
One of the most important decisions when choosing a furnace is matching its output to your home’s heating needs. A furnace that’s too small may struggle to keep your home warm, while an oversized system can short-cycle, waste energy and experience unnecessary wear. Essentially, bigger isn’t always better. Your home’s insulation, windows and layout can all affect its heating requirements.
Of course, you may not know your output, and that’s totally normal! A trained technician can perform a detailed load calculation to help determine the right furnace size for your home and Calgary’s climate.
5. Installation Costs
The cost of buying a new furnace goes beyond the initial price tag. Upfront costs can include the furnace itself, installation, ductwork and any system modifications required. Long-term costs can include energy consumption, maintenance and potential repairs.
An important thing to remember: the least expensive furnace upfront isn’t necessarily the least expensive to own over its lifespan. Professional installation is also worth factoring into your budget, as proper installation supports safe operation, performance and efficiency in the long-run.
6. Check Warranty Coverage and Maintenance Requirements
Warranty coverage is another important part of your new furnace checklist. When comparing furnaces, look at the length of the warranty, what parts or labour may be covered and any conditions that could affect your coverage.
Some warranties may have specific installation, registration or maintenance requirements, so make sure you understand what is expected from the furnace you choose. Regular maintenance can also help keep your furnace operating efficiently and reliably for years to come.
7. Consider Accessories and Controls
Consider pairing your furnace with accessories like programmable thermostats, humidifiers or air cleaners. These additions can improve comfort and indoor air quality and may also help you manage your home’s energy use.
8. Understand Furnace Efficiency and AFUE Ratings
Look for furnaces with a high AFUE (Annual Fuel Utilization Efficiency) rating. AFUE indicates how efficiently a furnace converts fuel into heat for your home.
For example, a furnace with a 95% AFUE rating converts approximately 95% of the fuel it uses into heat for your home, with the remaining energy lost during the heating process. A higher-efficiency furnace may cost more upfront but could help reduce energy consumption and heating costs over time.
9. Choose the Right HVAC Company
When it comes to your home, the professionals you choose make a difference. Look for an HVAC company with experience and qualified technicians that can offer clear, personalized recommendations, transparent pricing, warranty and service support, and reliable ongoing maintenance.
The furnace you choose matters, but so does the company installing it.
10. Overall HVAC System Compatibility
If you plan to pair your furnace with an air conditioner or heat pump now or in the future, consider how the equipment will work together. Coordinating equipment upgrades can sometimes save money and help improve the efficiency and performance of your overall HVAC system.
