Lennox furnace installation Guelph by HVAC-GROUP. Starting from $3,940 + HST for basic installation, with free in-home estimates and 1-year installation warranty.
Recently, our team completed a furnace replacement in Guelph, Ontario, replacing an 18 year old Carrier furnace with a new Lennox Merit Series ML296UH090XV48CK high-efficiency gas furnace.
The existing Carrier furnace had reached the point where its blower motor stopped working. Instead of investing in a major repair on an aging furnace, the homeowner chose to replace the system with a modern two stage, variable speed Lennox furnace.
This furnace installation included new intake and exhaust vent pipes, a modified plenum connection, a new 16 × 25 × 1 filter rack, reconnection of the existing 1/2 inch gas line, and connection to the home’s existing thermostat and air conditioning system.

Why This Guelph Furnace Was Replaced
The original furnace was a Carrier furnace approximately 18 years old.
The immediate problem was a failed blower motor. When an older furnace develops a major component failure, homeowners need to consider both the repair cost and the remaining service life of the equipment.
In this case, the homeowner chose furnace replacement instead of continuing to invest in an aging furnace.
Installing a new high efficiency furnace also provided an opportunity to improve the heating system with two stage operation and a variable speed blower.
What Was Included in This Lennox Furnace Installation?
This was a furnace replacement, not a completely new HVAC installation.
The existing Carrier furnace was removed and replaced with the new Lennox ML296UH090XV48CK.
New Furnace Venting
The new Lennox high efficiency furnace required new intake and exhaust venting.
We installed:
- New fresh air intake vent pipe
- New exhaust vent pipe
- New connections to the furnace
- Proper venting configuration for the new high efficiency furnace
Replacing the venting is an important part of many high efficiency furnace installations because the venting requirements can be different from those of an older furnace.
Existing Gas Line Reconnected
The home’s existing 1/2-inch natural gas line was reused and reconnected to the new furnace.
The gas connection was completed as part of the furnace replacement and the system was checked during startup and testing.
Plenum Modification
The old Carrier furnace was taller than the new Lennox furnace.
Because of the difference in furnace height, the existing supply plenum needed to be modified.
We extended the plenum to properly connect the existing ductwork to the new Lennox furnace.
This is one reason why furnace replacement is not always simply a matter of removing the old furnace and putting the new furnace in exactly the same position.
The new equipment must be properly connected to the home’s existing duct system.
Existing Thermostat and Air Conditioner
The existing thermostat was kept and connected to the new Lennox furnace.
The existing air conditioner was also retained.
No new air conditioner was installed during this project. The new Lennox furnace was paired with the home’s existing AC system.
When replacing a furnace, an existing air conditioner may sometimes be retained if the equipment is still suitable and compatible with the new heating system.
The condition and compatibility of the furnace, indoor coil, air conditioner, refrigerant system, airflow, and controls should be considered before deciding whether to keep an existing AC system.
Benefits of a Two Stage Lennox Furnace
The Lennox ML296UH090XV48CK uses two stage heating.
Instead of operating only at full heating capacity, a two stage furnace can operate at a lower heating level when the home does not require maximum heat and move to the higher stage when additional heating capacity is required.
This can provide several potential comfort advantages:
- More consistent indoor temperatures
- Longer heating cycles
- Reduced temperature swings
- Quieter operation during lower stage heating
- Better comfort during milder weather
- Improved airflow control when combined with a variable speed blower
Actual system performance depends on the home, ductwork, thermostat configuration, furnace setup, and heating requirements.
Variable Speed Blower for Better Airflow
Another important feature of the Lennox ML296UH is its variable speed blower.
Unlike a basic single speed blower that generally operates at one fixed speed, a variable speed blower can operate at different airflow levels depending on the system’s requirements.
This can help provide more gradual and consistent airflow throughout the home.
The blower also allows the furnace installation to be configured according to the home’s ductwork and airflow requirements.
96% AFUE High Efficiency Furnace
The Lennox ML296UH090XV48CK is rated at 96% AFUE.
AFUE stands for Annual Fuel Utilization Efficiency. It is a measurement used to describe how efficiently a gas furnace converts fuel into usable heat over the heating season.
A 96% AFUE furnace is considered a high efficiency condensing furnace.
Compared with an older furnace, a modern high efficiency furnace may use less natural gas to produce the same amount of usable heat. However, actual energy savings depend on the efficiency of the previous furnace, heating demand, thermostat settings, insulation, weather, ductwork, and how the system is operated.
Why Proper Furnace Sizing Matters
Choosing a furnace should not be based only on the BTU rating.
The correct furnace size depends on the heating requirements of the home.
Important factors can include:
- Home size
- Insulation
- Windows and doors
- Ceiling height
- Building construction
- Local climate
- Ductwork
- Airflow requirements
An oversized furnace can cycle on and off too frequently, while an undersized furnace may have difficulty maintaining the desired indoor temperature during very cold weather.
For this reason, a professional furnace installation should consider the home’s heating requirements, existing ductwork, airflow, and installation conditions before selecting the replacement equipment.
