Building a new home requires careful planning for every mechanical system, and the HVAC system is one of the most important parts of the house. Proper design and installation of a forced air heating and cooling system ensures comfort, air quality, and energy efficiency for many years.
At HVAC-GROUP, we specialize in new construction HVAC systems, ductwork installation, furnace installation, air conditioning systems, HRV ventilation, gas line installation, and mechanical system design support for custom homes.
If you are a builder, contractor, or homeowner planning a new construction project, you can send your HVAC mechanical drawings to our team at:
📧 info@hvac-group.com
Our process is simple:
- Send us your HVAC mechanical drawings
- We review the drawings and calculate the scope of work
- We provide a detailed HVAC estimate
- If needed, we schedule a site visit to review the project
Recently our team completed a new construction HVAC project in Etobicoke, where we installed a complete forced air HVAC system for a 6100 sq.ft custom home.
New Construction HVAC Project in Etobicoke, Toronto
For this project, HVAC-Group was hired by the homeowner to design and install the complete forced air heating and cooling system.
Project Location: Roxaline St, Etobicoke, Ontario
The custom home has approximately 6100 square feet of living space, which required two independent HVAC systems to properly heat and cool the entire house.
Our scope of work included:
- Complete ductwork installation
- Two high efficiency furnace systems
- Two central air conditioning systems
- Heat Recovery Ventilation (HRV) installation
- Gas line installation for multiple appliances
- Smart thermostat installation
- Tankless water heater installation
Each system was designed and installed according to the HVAC mechanical drawings provided for the project.
Basement and First Floor Heating System
The first HVAC system was designed to serve the basement and the main floor of the home.
Furnace Installation
For this area we installed:
Goodman High Efficiency Natural Gas Furnace
- 80,000 BTU capacity
- Two-stage heating system
- Variable speed blower motor
Two-stage furnaces are a great option for new construction homes because they improve:
- indoor comfort
- temperature consistency
- energy efficiency
- humidity control
Ductwork Installation for Basement and Main Floor
Our team installed complete supply and return ductwork according to the HVAC mechanical drawings.
Important installation details included:
- Properly sized supply ducts
- Return air duct system
- Balancing dampers installed on each supply vent
- All ductwork sealed for maximum efficiency
Balancing dampers allow the HVAC technician to adjust airflow to each room, ensuring every space receives the proper amount of heating and cooling.
HRV Ventilation System Installation
To improve indoor air quality, we installed a: Lifebreath 150 CFM Heat Recovery Ventilator (HRV)
The HRV system was connected to the new ductwork and provides:
- Fresh outdoor air
- Removal of stale indoor air
- Better humidity control
- Improved indoor air quality
A new HRV controller was also installed to allow the homeowner to easily control ventilation levels throughout the house.
Cooling System for Basement and Main Floor
For the cooling system we installed: Goodman 3.5 Ton Central Air Conditioning System
Components included:
- 3.5 ton outdoor condenser
- Matching ADP A-coil
- Refrigeration line set
- Communication wiring
- Outdoor condenser brackets
- Electrical disconnect box
This system provides efficient cooling for the basement and main floor areas of the house.
Second Floor HVAC System Installation
Because of the size of the home, a separate HVAC system was installed for the second floor.
This allows homeowners to maintain better temperature control between floors, which is very important in larger houses.
Second Floor Furnace
For the second floor system we installed: Goodman High Efficiency Furnace
- 60,000 BTU capacity
- Two-stage heating
- Variable speed blower motor
- New filter rack
This furnace provides reliable heating for all second floor bedrooms and living spaces.
Ductwork Design for the Second Floor
One important design feature of this project was installing ductwork through the attic space.
Supply vents were installed in the attic so that no duct boxes were required inside the second floor ceiling.
This approach helps maintain a clean interior design without bulkheads or boxed ducts.
However, it is extremely important that ductwork located in unconditioned spaces is properly insulated.
Attic Ductwork Insulation
Any ductwork that runs through:
- attic spaces
- garages
- other unconditioned areas
Should be spray foam insulated.
Spray foam insulation helps prevent:
- heat loss
- condensation
- energy waste
HVAC-Group works with trusted spray foam contractors, and we often recommend these specialists to our clients during new construction projects.
Second Floor Cooling System
For cooling the second floor we installed: Goodman 2.5 Ton Central Air Conditioner
System components included:
- 2.5 ton condenser
- Matching A-coil
- Refrigeration line set
- Communication wiring
This system provides efficient cooling for all second floor rooms.
Smart Thermostat Installation
Instead of installing standard programmable thermostats, the homeowner chose to upgrade to Ecobee Smart Thermostats with built-in Alexa.
Two thermostats were installed:
First Floor Thermostat
Controls:
- Basement heating and cooling
- First floor heating and cooling
Second Floor Thermostat
Controls:
- Entire second floor HVAC system
Smart thermostats help homeowners:
- control temperature remotely
- improve energy efficiency
- monitor HVAC system performance
Tankless Water Heater Installation
Mechanical drawings often do not include detailed water heater specifications, so HVAC contractors usually assist homeowners with choosing the best option.
Common options include:
- 40–60 gallon traditional water heater tanks
- Tankless water heaters
For this large custom home, we recommended installing a: Navien NPE-240S2 Tankless Water Heater
This system provides:
- High efficiency hot water production
- Continuous hot water supply
- Better performance for larger families
Tankless water heaters are a great solution for large homes with multiple bathrooms and higher hot water demand.
Gas Line Installation for Multiple Appliances
This home required gas supply for several appliances:
- Two furnaces
- Tankless water heater
- Gas stove
- Two fireplaces
- Outdoor BBQ
To properly design the gas piping system we first calculated the total BTU demand for all appliances.
Based on these calculations, we installed:
1½ inch main gas line from the gas meter to the mechanical room.
From the mechanical room we built a gas manifold system, which allowed us to run separate gas lines to each appliance.
Gas line sizing always depends on:
- total BTU demand
- distance from gas meter
- number of appliances
Because of this, gas line installation is always calculated separately for each project.
Final HVAC System Testing and Warranty
After installation was completed, all equipment was:
- Started and tested
- Checked for proper airflow
- Verified for correct gas pressure
- Inspected for system performance
All equipment installed by HVAC-Group comes with:
- HVAC-Group installation warranty
- Goodman manufacturer warranty (10 years on parts when registered)
This gives homeowners peace of mind knowing their new HVAC system is properly installed and protected.
FAQ – New Construction HVAC Systems in Etobicoke
What HVAC system is best for a new home?
Most custom homes in the GTA use forced air HVAC systems with high efficiency furnaces and central air conditioning. These systems provide reliable heating, cooling, and ventilation.
Do new homes need two HVAC systems?
Large homes over 3500–4000 square feet often benefit from two HVAC systems. This allows better temperature control between floors and improves comfort.
When should HVAC contractors be involved in new construction?
HVAC contractors should be involved early in the construction process, ideally when mechanical drawings are ready. This ensures proper duct design and equipment sizing.
How much does HVAC installation cost for a new home?
The cost depends on:
- house size
- number of systems
- ductwork complexity
- ventilation systems
