Sherbrooke & the Eastern Townships
The number your quote should give you
It is called the balance point: the temperature at which your heat pump stops carrying the house alone. It can be calculated. Most quotes never mention it, and that is the whole difference between a system and a sale.
What we do
Install it, keep it running, fix it
Six services in three families. The middle one is where most of your money gets saved, and it is the one people skip.
Heat pump installation
Wall-mounted or central heat pump, sized from a load calculation rather than square footage, with a balance point calculated for our winters.
Central air conditioning
A central system tied into existing ductwork, after verifying the ducts can actually carry the required airflow.
Heat recovery ventilator
Installing and balancing a heat recovery ventilator, required by code in new homes and often badly set in the rest.
How we work
A sealed circuit does not consume refrigerant
If yours needs a top-up every year, it is leaking and somebody is not looking for the leak. Recharging without finding it is filling a punctured bucket — and it is the most common way a repair bill becomes a subscription.
- Load calculation before any equipment is proposed
- Balance point stated in writing on the quote
- Ductwork static pressure measured before tying in
- Diagnostic billed and credited — so we look for the real cause
- Six measured readings on every maintenance report

Reviews
Often about what we refused to sell
Three quotes received, three different units proposed. Point Zéro was the only one that ran a load calculation before proposing anything. The unit they recommended was smaller than the other two, and it is more than adequate.
They told me plainly that at minus twenty-five the heat pump would not carry the house alone and that a backup was needed. The previous salesman had promised the opposite. Two winters later, they were right.
The diagnostic cost something, which annoyed me at first. But they found a dead capacitor in twenty minutes instead of selling me a compressor. The final bill was a tenth of what I feared.
A cottage rented by the week. They set the ventilator to run at minimum when nobody is there, and the humidity stopped climbing between stays. Nobody had ever mentioned that setting to me.
They refused to install central air on my existing ducts without modifying them. I thought that was excessive. Another contractor confirmed it afterward: the ducts were half the size they needed to be.
The annual maintenance report gives measured pressures and temperatures, not just a checked box. I could see the degradation year over year and plan the replacement instead of having it forced on me.

Worth reading before you compare quotes
At what temperature your heat pump stops being enough
It is called the balance point, it can be calculated, and it is the number most quotes never mention.
An oversized heat pump heats worse
It is counterintuitive and it is the most frequent error in this trade. An oversized unit short-cycles, dehumidifies poorly and wears out faster.
What actually moves the price of a central system
The unit itself is rarely the dominant line. The condition of the existing ductwork is what decides the gap between two quotes.
