Both are industry leaders with strong reputations, but they take slightly different approaches to heating technology, reliability, and long-term ownership costs. If you’re deciding between Carrier and Lennox for your next furnace upgrade, this guide breaks down efficiency, reliability, noise, cost, warranties, and overall value to help you make an informed decision.

Carrier Furnaces

Carrier is known for balanced performance and reliability. Their furnaces are designed for durability, consistent comfort, and wide availability of replacement parts.

Hello, BC homeowners! With colder seasons looming, many of us are considering ways to not only keep our homes warm but to do so efficiently and sustainably. Fortunately, the province of British Columbia has consistently shown its commitment to promoting energy-efficient appliances and systems. If you're thinking about upgrading your home heating system, you're in luck. BC offers several rebates for high-efficiency furnaces. Let's delve into what's available for 2023. Why High-Efficiency Furnaces? Before diving into the rebates, it's essential to understand why high-efficiency furnaces are gaining traction. These systems operate at a higher Annual Fuel Utilization Efficiency (AFUE) rating, meaning they convert a higher percentage of the fuel they use into heat. This not only reduces your energy bill but also cuts down on carbon emissions, benefiting both your wallet and the environment. BC Hydro and FortisBC Rebate Program: BC Hydro and FortisBC have been key players in promoting energy efficiency in the province. They frequently collaborate on rebates and incentives for homeowners. Furnace Replacement Program : Homeowners who replace their old natural gas furnace with an eligible ENERGY STAR model can get a rebate. The exact rebate amount tends to vary, but it often ranges from $500 to $1000. To qualify, ensure your new furnace has a two-stage or modulating burner with an Electronically Commutated Motor (ECM). Combo Rebate : If you're thinking of upgrading multiple systems, there are often combo rebates available. For instance, if you install a new natural gas furnace along with a connected thermostat or an eligible water heater, you might qualify for an additional rebate. CleanBC Home Efficiency Rebates: CleanBC is another significant program that offers rebates for energy-efficient home improvements.  High-Efficiency Furnace Upgrade : CleanBC often offers incentives for homeowners who replace their old gas furnace with a high-efficiency model. These rebates typically complement those offered by BC Hydro and FortisBC. Other Upgrades : Beyond furnaces, CleanBC provides rebates for other energy-efficient upgrades, such as insulation, water heaters, and windows. If you're undertaking a larger home renovation, these can add up to substantial savings. Things to Remember: Pre and Post-Inspection : Some rebate programs may require a home energy audit or inspection before and/or after the furnace installation. This helps determine your home's energy efficiency before the upgrade and verifies the installation afterward. Documentation : Always keep your purchase receipts, old and new furnace details, and any other relevant paperwork. They'll be needed when applying for the rebate. Qualified Contractors : Many rebates require the installation to be performed by a qualified contractor. Always check the program's terms and conditions. Deadlines : Most rebate programs have application deadlines. Ensure you're aware of them and submit your application promptly. Final Thoughts: Upgrading to a high-efficiency furnace in British Columbia not only means a cozier home in the winter but also significant potential savings with these rebates. By taking advantage of these programs, homeowners can recover a portion of their investment and enjoy lower energy bills over time. Remember that rebate programs can evolve, and details may change. Always refer to the respective official program websites or consult with professionals for the most up-to-date information. Stay warm and eco-friendly, BC!
