Wall-mounted heat pumps

General

What is included with rental?
  • The device and installation by certified professionals.
  • Preventive maintenance every 3 years: filters will be cleaned and a full visual inspection will be carried out*.
  • 12-year lease term.
  • Parts and repairs required during the lease term.
  • Transfer of lease: If you sell your home or move, it is important to declare the lease to the new owner or tenant. The new owner or tenant will be responsible for the remaining term of the lease.
  • Option of terminating the lease by purchasing the device in line with a depreciation table according to the device’s age.
* In line with technical criteria set by HydroSolution.
What is a BTU?
The British Thermal Unit (BTU) is a unit of heat that defines the quantity of heat necessary to raise the temperature of one pound of water by one degree Fahrenheit at a constant pressure of one atmospheric unity.
What is the Energy Efficiency Ratio (EER)?
The energy-efficiency ratio (EER) corresponds to the efficiency of an air conditioner at 35 oC (outdoor) and 26 oC (indoor) with a humidity level of 50%. The higher the EER, the more efficient it is and as a result, the lower the energy consumption. A 1-point difference in the EER rating corresponds to approximately a 4% difference on the cost of electricity.
What is the Heating Seasonal Performance Factor (HSPF)?
The heating seasonal performance factor corresponds to the efficiency of a heating system at 8 oC (outdoor) and 20 oC (indoor). The higher the HSPF, the more efficient it is and as a result, the lower the energy consumption. A 1-point difference in the HSPF rating corresponds to approximately an 8% difference on the cost of electricity.
What is the coefficient of performance (COP)?
This is the ratio between the energy consumed and the quantity of heat produced. The higher the COP, the more efficient it is in heating mode. A COP of 3 means the device will consume 1 KW/h to produce a heat output of KW/h.
What is the Seasonal Energy Efficiency Ratio (SEER)?
This measures an air conditioner’s performance at 28 oC (outdoor) and 20 oC (indoor). The higher the SEER, the more efficient it is and as a result, the less energy it consumes. A 1-point difference in the SEER rating corresponds to approximately a 4% difference on the cost of electricity. This measure is not commonly used because it is assessed in variable conditions and is therefore less reliable than the EER rating.
What is Inverter technology?
Inverter technology modulates the heat pump in order to maintain a more constant temperature. The device can then reach the desired temperature more quickly while remaining constant by regulating the speed of the compressor. The motor therefore does not come to a full stop as often and the temperature remains more stable. This increases the lifespan of the device and results in lower costs.
What is ENERGY STAR?
ENERGY STAR is an internationally renowned certification system attesting to a product’s energy efficiency. A heat pump with this designation must reach a minimum SEER rating of 15, an EER rating of 12.5, and an HSPF of 8.5.
What are the differences between a heat pump and an air conditioner?
In addition to cooling your space in the summer, a heat pump can provide heat in the winter. An air conditioner only works a few months out of the year. A wall-mounted heat pump relies on the same principle as the air conditioner to transform the hot air outside into cool air during the summer months and turns cold air into hot air in the winter. It can therefore be used year-round because it reuses the energy of the cold outside to heat your home thereby lowering your electricity bill.
Is a single wall-mounted unit sufficient for a home with multiple levels?
That really depends on your home’s architecture, size, and configuration. It also depends on the number of levels and closed rooms in comparison with open spaces. And don’t forget to take your expectations and priorities into account. A visit from a representative may be necessary for us to make the right recommendation.

How do I know how many BTUs are required to keep me comfortable?
To find out how many BTUs are required, calculate your surface area (length x width), multiply by 10 and round up to the corresponding number of BTUs. For instance, an area with 1,000 sq. ft. requires 12,000 BTUs.

Example: 26 ft x 38 ft = 988 sq. ft.
988 X 10 = 9,880 > rounded up = 10,000
Number of BTUs required = 12,000 (higher number)
Can I get a heat pump from HydroSolution if I am a tenant?
Yes but you need your landlord’s authorization and come to an agreement with them regarding the payment after you leave your apartment because they will then be responsible for the payments.
Can my outdoor unit be installed on the ground?
Yes but you’ll have to carry out the work before the refrigeration technicians arrive. If you cannot install it directly on the existing structure, you must install some sort of support such as patio stones or a concrete structure. You will be responsible for preparing the ground for the installation of the unit.
Are the wall-mounted units installed by specialists?
Our refrigeration technicians are specialized in the installation of ventilation and air conditioners.
Do you provide installation everywhere?
We offer our services in Greater Montreal, Quebec City, Gatineau, the South Shore, Mauricie, the Eastern Townships, Rimouski, and Saguenay.
What kind of financing is available?
For now, only the rental option is available.

Can I get a grant?
Yes, but only the Performance model is eligible for governmental assistance. You’ll find more information at https://transitionenergetique.gouv.qc.ca/en/residential/programs/heat-pumps

Installation of a heat pump is eligible for financial assistance as part of the Chauffez vert, Rénoclimat, Novoclimat Homes and Novoclimat Small Multiple-Unit Buildings programs.

The heat pump selected must appear on the list of eligible models at the time of installation and all program conditions must be met.
