What is the total cost of Lennox furnace installation, including labor and materials?

The cost of furnace installation ranges from $1,000 to $1,600, depending on the brand and model of the furnace, as well as the existing conditions. The installation includes the cost of running PVC piping for the flue vent to the side wall of the house, modifying ducts, setting up the air filtration system, installing drain pipes, wiring the thermostat, and connecting gas piping for the new furnace. It is crucial to have a qualified contractor perform the installation to ensure that the gas piping and flue vents are installed correctly, as improper installation can pose serious hazards.

How Reliable is the Lennox Furnace?

Lennox is a prominent name in the HVAC industry, known for its extensive history in producing heating and cooling equipment. The brand is recognized for the high quality of its products, which come with dependable warranties. Lennox systems are designed for low maintenance, and the associated repair costs tend to be reasonable due to the wide availability of parts. Furthermore, many gas technicians are well-acquainted with Lennox equipment, enhancing accessibility to support and service for users.

Are there additional costs for ductwork modifications or other upgrades?

Typically, the cost of installation includes most scenarios for furnace replacement, except in cases involving an oil furnace or a furnace installed in the 1980s or earlier. In these situations, the cost of ductwork may be significantly higher, as the entire cold air return duct will need to be replaced, and the existing gas piping may not be compatible with the new systems.

Does Lennox Furnace Work with My Existing HVAC System?

The Lennox Merit and Elite series are 100% compatible with any type of HVAC system. Whether your existing system is very old or fully smart, Lennox products can easily adapt to the current setup. The most important factor is that the installation should be performed by an experienced gas technician and a reliable company to ensure quality support and installation.

Are there dual-fuel or hybrid Furnace options available?

Yes, you can buy a standard gas furnace and add a heat pump unit to your HVAC system. The heat pump is efficient enough to provide heating even when outdoor temperatures reach as low as -25 degrees Celsius. You can rely on natural gas only for emergency heating or as a backup system. Additionally, hybrid systems qualify for the Ontario Greener Homes rebate program.

Can I finance the Lennox furnace?

4Most Energy offers various financing options that change from month to month. Typically, during the slower season, the financing options become more attractive, featuring lower interest rates and sometimes even zero interest. Please consult your sales representative to find the best options based on your credit history and the amount of your purchase.
