What is the COP of a heat pump?

How is the COP calculated on a heat pump? If you're looking for a wall-mounted or central heat pump, you've probably heard the word or abbreviation COP. The term COP stands for Coefficient of Performance. The COP is actually a ratio of energy consumption versus the amount of heat produced by a heat pump or other device. Each device is evaluated according to their heating performance using the COP. In other words, the higher the COP, the more the device...

Inverter compressor technology

What is an Inverter Compressor?

The word "Inverter" is a technology that allows the compressor to modulate the cooling output of your air conditioning system. The majority of air conditioning systems today have inverter technology and here's why:   Indoor temperature accuracyThanks to the capacity modulation of the compressor, the temperature will be more stable, because the temperature sensor indicates to the indoor unit the required capacity. Superior energy savingThe compressor will significantly reduce its power when the temperature is reached and will provide...

The static pressure of a ventilation system

What is the static pressure of a ventilation system used for?

Measuring the total external static pressure of a ventilation system is extremely important. This assesses the existing duct system and installation conditions. This simple test can help you uncover problems associated with restricted duct systems that are invisible to those who don't measure. Here is the easiest way to explain the static pressure of a ventilation system. This way is to compare it to blood pressure. This comparison is a great...

The Danger of Unlicensed Contractors

The Danger of Unlicensed Contractors for your installation

As a licensed air conditioning, heating and ventilation contractor, our technicians are often called into homes where a system has broken down. After running diagnostics on the system, it is easy to see that the previous work was done wrong by an unlicensed worker. Sometimes the owner can no longer reach the person responsible for the installation and calls us in great frustration. Most of the time, the owner has already tried to...

How a heat pump works

How a heat pump works

During the heating season, a heat pump can be very economical in terms of energy consumption if it is well chosen according to your needs. Heat pump air conditioning units heat your home using heat from the air and heat from the refrigerant. The majority of the heating power of your heat pump is produced thanks to the compressor which circulates the refrigerant in the refrigeration circuit. The refrigerant is a liquid which has several...

What is the EER rating ?

How is the EER calculated on an air conditioner?

If you are looking for an air conditioner or a heat pump, you have probably already heard of or simply noticed the abbreviation EER. The term EER stands for Energy Efficiency Ratio. In French, you will find the abbreviation TRÉ which means Energy Efficiency Rate. The EER is calculated using an outdoor temperature of 35°C, an indoor temperature of 26°C and a humidity level of 50%. No seasonal temperature changes are considered...

What is the HSPF rating ?

How is the HSPF calculated on a heat pump?

If you're looking for an air conditioner or a heat pump, you've probably heard of the abbreviation HSPF. The term HSPF stands for Heating Seasonal Performance Factor. In French, you will find the abbreviation FRSC which means Factor of Seasonal Efficiency in Heating. The HSPF is actually a ratio or rating of energy efficiency that each device is evaluated according to their heating performance. In other words, the higher the HSPF, the...

What is the SEER rating ?

How is the SEER calculated on an air conditioner?

If you're looking for an air conditioner or wall mounted heat pump, you've probably heard of the abbreviation SEER. The term SEER stands for Seasonal Energy Efficiency Ratio. In French, you will find the abbreviation TRÉS which means Seasonal Energy Efficiency Rate. The SEER is actually an energy efficiency ratio that each appliance is rated according to their performance. In other words, the higher the SEER, the less energy the appliance will...
