Choosing and installing the right central heat pump can completely transform your home comfort, improve indoor air quality, reduce your energy bills, and make you eligible for generous grants. But poor planning or uninformed decisions can have the opposite effect. At AirGreen, we support homeowners and property managers across Montréal, Laval, Longueuil, the North Shore, and the South Shore through every step of the central HVAC installation, anticipating obstacles and offering tailor-made solutions. Here are 5 essential things to consider before installing a central heat pump, to avoid any unpleasant surprises.
1. Choosing the right model for your home (and your needs)
One of the most common pitfalls when installing a central heat pump is choosing a unit that doesn’t match your home’s square footage, insulation, or type of property. An oversized unit will cycle on and off too frequently, lowering efficiency and shortening its lifespan. On the other hand, an undersized unit will struggle to properly heat or cool your space, especially during winter.
At AirGreen, we perform a full evaluation of your building: square footage, room layout, insulation level, type of windows, sun exposure, and more. This allows us to recommend the correct BTU sizing and guide you toward the best brands we install: Bosch, Lennox, Trane, Fujitsu, Gree, Goodman, ACD, Zephyr, and more.
Things to check:
-
Total area to cover
-
Ceiling height
-
Number of zones needing independent control
-
Whether or not an existing duct system is in place
2. Assessing the condition (and compatibility) of your existing ductwork
Many homeowners overlook the importance of ductwork in an HVAC installation. But even the best central heat pump won’t perform well if the ducts are poorly insulated, leaky, or badly designed. A static pressure test can reveal substantial air loss that could compromise system efficiency.
At AirGreen, before starting any project, we thoroughly inspect the existing duct system—its diameter, condition, insulation, and layout. If modifications, replacements, or improvements are needed, we include this in our planning to ensure optimal long-term performance.
3. Taking advantage of available grants in Montréal, Laval, Longueuil, North Shore, and South Shore
Installing a central heat pump may qualify you for significant financial assistance, but only if you know the right programs and choose a qualifying model. For example, the Hydro-Québec LogisVert program offers grants of several thousand dollars, depending on the model and energy efficiency of your system.
AirGreen guides you through this process. We’re fully familiar with the eligibility requirements and we help you put together your grant application, step by step.
Real-world example:
We recently installed a 5-ton Bosch BOVA central heat pump in Laval. Thanks to its SEER rating above 18, our client received a $6,650 grant through the LogisVert program while also cutting their energy costs by more than 40% compared to their old oil heating system.
4. Anticipating the electrical work required
A central heat pump requires a dedicated electrical supply, often 240 volts, with an appropriate breaker. It’s common for existing electrical panels to be full or not meet current standards for this type of unit.
That’s why our technical teams work with certified master electricians. Before each installation, we assess the available electrical capacity and plan any required changes, such as wire runs, breaker upgrades, or even installing a subpanel if needed.
Pro tip:
Factor this step into your initial budget. While AirGreen always works to keep costs reasonable, it’s essential to not overlook the electrical aspect, or you may face delays or unexpected expenses.
5. Understanding the maintenance required to preserve performance
A high-performing central heat pump is also one that’s well-maintained. Filters must be cleaned or replaced regularly, coils need to stay clean, and the outdoor unit should remain clear of debris or obstruction.
At AirGreen, we offer preventive maintenance plans, tailored to each installation, to avoid premature wear and maintain peak performance year after year. During installation, we train each client in best maintenance practices, and also offer professional servicing visits.
Real-world installations successfully completed by AirGreen
Montréal (Rosemont) – Installation of a 3-ton Fujitsu Airstage R-32
Ms. Beaudoin’s home was previously heated with an outdated natural gas system. We replaced it with a 36,000 BTU Fujitsu Airstage KZAH central heat pump, with a SEER efficiency of 18.5. Despite the limited basement space for the air handler, we successfully redesigned the mechanical layout. The result: a quieter, more comfortable home and a 38% reduction in energy bills.
Longueuil – Replacing an electric system with a 3-ton Bosch IDS Premium
Mr. D’Amours was looking to replace his energy-hungry electric system. We installed a Bosch IDS Premium R-454B, which qualified for a $4,100 grant. With perfect integration into the existing ductwork and a multizone control setup, the home now enjoys even thermal comfort all year long.
Our advice to avoid the most common mistakes
-
Don’t focus only on the upfront price. A cheaper but poorly matched unit will cost more in the long run.
-
Don’t neglect maintenance. A simple annual cleaning can extend your heat pump’s lifespan by years.
-
Choose a certified, experienced installer. At AirGreen, we’re accredited by leading brands and have proven expertise from hundreds of installations across Greater Montréal.
