Common Mistakes to Avoid During Furnace Installation in Ontario Installing a new furnace is one of the most important decisions for any homeowner, especially in a province like Ontario where winters are long, cold, and demand reliable heating. A furnace plays a key role in maintaining comfort and energy efficiency, but the installation process is just as important as the unit you choose. Many homeowners unknowingly make mistakes that lead to higher energy bills, reduced lifespan of the furnace, and costly repairs in the future. Understanding what to avoid can help you ensure a smooth, efficient, and safe setup.
1. Choosing the Wrong Furnace Size One of the most common mistakes during furnace installation is selecting an incorrect size. A unit that is too small will struggle to heat your home, running constantly and raising utility costs. On the other hand, a furnace that is too large will heat too quickly, causing frequent on-and-off cycling which leads to wear and tear. Proper sizing requires calculation of heat load based on square footage, insulation quality, number of windows, and climate. It’s always best to consult an HVAC expert for accurate assessment rather than guessing.
2. Installing a Furnace Without Professional Help Many homeowners try DIY installation to save money, but this often results in hazardous or inefficient outcomes. Furnace installation involves electrical connections, gas lines, ventilation setup, and safety regulations. Incorrect installation can lead to carbon monoxide leaks, high energy consumption, or complete system failure. Hiring certified professionals ensures that the system is installed safely, correctly, and according to Ontario building codes. DIY might seem cheaper upfront, but professional work saves thousands in long-term repair and operating costs.
3. Ignoring Ventilation and Airflow Requirements Furnaces need proper ventilation to remove combustion gases and supply fresh air. Poor duct design or blocked vents can restrict airflow, reducing heating performance and causing overheating. This is especially important for modern high-efficiency units, which often require specific venting arrangements. Before installation, a technician should inspect the ductwork, check for leaks, and ensure proper sizing to support the new system. Neglecting ventilation can reduce system lifespan and compromise indoor air quality.
4. Overlooking Energy Efficiency
Not all furnaces operate at the same efficiency level. Focusing only on price and ignoring efficiency ratings can cost more in the long run. High-efficiency furnaces may require a slightly higher investment, but they reduce monthly heating bills significantly. Look for AFUE (Annual Fuel Utilization Efficiency) ratings, and choose a model suitable for Ontario’s climate. Efficient systems also provide better performance, quieter operation, and longer lifespan. A professional installer can suggest the right option based on your home.
5. Skipping a Home Heat Load Calculation Homeowners sometimes pick a furnace based on their old system or general assumptions. However, homes change over time—windows, insulation, or room additions affect heating needs. A proper heat load calculation considers all these factors to determine the furnace size required for consistent heating. Without this calculation, you risk uneven temperatures and operational inefficiencies.
6. Choosing the Lowest Bid Without Research While it's tempting to go with the cheapest installer, low-cost quotes often mean shortcuts, unlicensed work, or lack of warranty coverage. A furnace is a long-term investment, and installation quality directly affects performance. Always evaluate experience, reputation, certifications, and customer reviews before hiring a contractor. Quality work ensures safety and efficiency for years.
7. Forgetting About Thermostat Compatibility Many modern furnaces work best with smart or programmable thermostats. Installing a new system with an outdated thermostat can limit energy savings and performance. A professional installer can recommend compatible controls that help you manage temperature more efficiently and reduce heating costs during Ontario’s winter months.
8. No Maintenance Plan After Installation
Even after proper installation, a furnace needs maintenance to run smoothly. Skipping annual check-ups can lead to breakdowns, dirty filters, and reduced efficiency. Regular tune-ups prevent expensive repairs and keep your system operating at peak performance. A maintenance plan also ensures warranty validity, which is often overlooked by homeowners.
