Case study: real installations by AirGreen

Laval – Nguyen Family: Stable Heat, Reduced Bills

In December 2024, we installed a Zephyr 4-Ton in a single-story house in Laval. Within the first month of use, the family noticed a 28% reduction in their electricity bill compared to their previous dual-energy system.

“The control is intuitive, the comfort is consistent, and AirGreen’s service has been impeccable.” – Ms. Thi, Laval

Boucherville – Energy-efficient renovation project

As part of a major renovation project, a Boucherville family opted for this heat pump to replace an old oil-fired central system . The space was adapted to accommodate the new AH-648A indoor unit. Thanks to ENERGY STAR® certification, consumption has dropped dramatically.

“We took advantage of the LogisVert grant to reinvest in roof insulation.” – Julie P., Boucherville

Thi (Laval, Quebec, Canada)
Heating and air conditioning in one device, super convenient to manage

We needed a versatile unit to handle our harsh winters and hot summers. The Zephyr 4-ton central heat pump fulfills this mission perfectly. I especially appreciate its simple and clear control. And AirGreen patiently answered all our questions.

F
Fouad (Laval, Quebec, Canada)
Good energy efficiency, but some random noises

The Zephyr 4-ton central heat pump consumes little energy, which is a big plus. However, I sometimes hear small vibrating noises. Nothing dramatic, but it's surprising at first.

M
Marijana (Laval, Quebec, Canada)
Zephyr plus LogisVert was the perfect combo for our renovation

During our major home renovation, we used the LogisVert grant to help with costs, and the Thermopompe Centrale Zephyr 4-ton fit our new layout perfectly. AirGreen's technicians were polite, thorough, and left no mess behind. Highly recommended.

I
Irina (LaSalle, Quebec, Canada)
A little expensive despite the available LogisVert subsidy

Despite the LogisVert grant, the investment for the Zephyr Central Heat Pump remains significant. Nevertheless, the quality is there and the performance is decent. I just would have liked a more affordable initial cost.

C
Carole (Montreal, Quebec, Canada)
Efficient climate control but initial calibration took time

I went for the 4-ton Zephyr. At first, it took a couple of days to adjust the settings properly for max efficiency. Now it's performing admirably. AirGreen's hotline was super helpful in guiding me through the calibration process.

S
Sébastien (Châteauguay, Quebec, Canada)
Reliability is not there after a few months

I've already had to contact the manufacturer's customer service regarding a circuit board issue. The Zephyr Central Heat Pump cools well, but I would have liked it to be more robust. I'm disappointed to have to deal with these issues so soon.

HAS
Andrei (Châteauguay, Quebec, Canada)
Cools quickly even in the hottest summer weather

I'm impressed by the power of this Zephyr 4-ton central heat pump. Even during the heatwave, the house stayed effortlessly cool. The compressor is quiet, a real plus. Thanks to AirGreen for the excellent installation.

T
Thierry (Montreal, Quebec, Canada)
Efficient overall, but installation took longer than hoped

The new Zephyr 4-ton is saving me money, no doubt. However, the project got pushed back twice by a week. AirGreen apologized and still did a great job once they arrived. I'd still recommend this system for its performance.

Y
Youssef (Boucherville, Quebec, Canada)
A reliable system with neat features for energy saving

Got the 4-ton Zephyr installed in the spring. I enjoy the energy-saving mode, which seems to help reduce my bills. AirGreen's installers were efficient, though the scheduling was a bit tight. Overall, happy with the purchase.

I
Julie P. (Boucherville, Quebec, Canada)

The Zephyr 4-ton central heat pump perfectly fulfills its role of air conditioning and heating. The AirGreen team installed the unit quickly, leaving everything clean behind. I highly recommend this solution for its efficiency and service.
