A central heat pump system is designed to cool or heat a conditioned space by providing cooling in the summer and heating in the winter. The cooling is accomplished by metering liquid refrigerant with the use of a metering device to control the amount of liquid refrigerant entering the evaporator. This liquid then evaporates by absorbing heat from the conditioned space by the use of a fan motor. The refrigerant at this stage turns to a low-pressure gas, which then travels back to the compressor to be compressed and starts the process all over. The heating process occurs in the opposite way by the use of a four-way reversing valve. This valve changes the flow of the refrigerant so that the system is now conditioning the outside or pulling heat from the outside (due to the refrigerant being colder than the outside temperature) and dumping it inside the space.

We are so happy that we called Joel and his team to repair our furnace. We were without heat for a week or so. We had contacted a few companies and none were able to properly diagnose our problem, instead we had 3 parts replaced and our heating system still did not work! Hundreds of dollars later we were lucky to be referred to Knowledge HVAC (and that is the perfect name for them, because they are quite knowledgeable!) Joel was able to come the same day and diagnose the problem for us. We hired him and his team to repair our furnace the next day, they were fast and efficient and we now have some heat finally! We are so happy we called them. I give them 5 stars for excellent service! I will definitely call them again if needed and will recommend them to my friends and family. Very pleasant experience, very nice guys! Reasonable rates.

Aaron was very thorough and got our system running again
Andy Li
Had my furnace fixed by Odaine. Overall very satisfied with his service. Quick fix and detailed explanation. Will recommend.
Amazing service and courteous staff. Came the next day for emergency service and got my heat back on. Pricing wasn't too crazy either. Definitely recommend this company for your HVAC needs
Dmytro Nikulin
Installed Google Nest Power Connectots for Termostats. Good job!
Roberta Chaffe
Thank you for your quick, professional response regarding my commercial refrigeration! I would not hesitate to recommend this company!
Windy Hewitt
I called around for a quote, and Knowledge was the first to call back. He gave a quote and was able to help the very next day. Joel and his team is very friendly, professional and knowledgeable. Very reasonably priced. I had a gas line system installed on my food truck. They did an awesome job, and put in extra time to get the job done on schedule. The inspector was impressed with the installation, passed the inspection with no problem. Definitely recommend them to anyone!!!

Odaine was very competent, informative, polite, and thorough. He arrived early my permission and worked hard for a good review. He did a fantastic job. The company is fast and reliable.

Heat Pump working principle.

A typical heat pump system consists of two main components, a Condensing unit otherwise called an outdoor unit and an Evaporator Coil otherwise known as an indoor air handler unit. Both of these units contain various important components.

Outdoor Unit

The most important components in an outdoor unit are A circuit board, compressor, reversing valve, expansion valve, condenser coil, refrigerant and a fan motor. All these items are what makes the heat pump system operates in cooling or heating mode.

Condenser Coil and Fan Motor. 

The condenser coil operates as a heat exchanger regardless of the weather or season. However, in the cooling mode, the coil would release the heat absorbs by the refrigerant from the conditioned space. whereby, in the heating mode the coil would absorb the heat from the outdoor environment. The fan motor would pull outdoor air across the coil to facilitate the heat exchange.

Evaporator Coil or Indoor Unit

The indoor unit, commonly referred to as the Evaporator, contains a coil and a fan motor. The coil also acts as a heat exchanger during the heating and cooling season.  Therefore, in cooling mode, the refrigerant that flows through the evaporator would absorb the heat out of the conditioned space. However, in the heating mode, the refrigerant inside the evaporator would release its heat into the conditioned space. The fan is responsible for moving air across the Evaporator coil and throughout the conditioned space. 


The refrigerant is the substance that absorbs and rejects heat as it circulates throughout the heat pump system.


The compressor is the heart of the heat pump system. It is responsible to compresses the refrigerant from low to high-pressure gas. Therefore, its job is to pressurize the refrigerant and moves it throughout the system.

Reversing Valve or Four-Way Valve

This electronic control valve is responsible for reversing the flow of refrigerant during the heating or cooling process. It is controlled by the circuit board and will turn on and off during a defrosting cycle.

Expansion Valve

The expansion valve acts as a metering device, regulating the flow of the refrigerant as it passes through the system, allowing for a reduction of pressure and temperature of the refrigerant.

How does a Heat Pump Work?

A heat pump operates by transferring heat energy from the outside atmosphere and delivers it to the conditioned space. This action takes place by a source of heat to what is called a heat sink.  It move thermal energy in the opposite direction of spontaneous heat transfer, by absorbing heat from a cold space and releasing it to a warmer one. When discussing heat pump efficiencies, the following terms are commonly used: coefficient of performance (COP), seasonal coefficient of performance (SCOP) and seasonal performance factor (SPF). The more efficient a heat pump is, the less energy it consumes and the more cost-effective it is to operate. There are several factors that will affect the efficiency of a system such as  heat pump repair, heat pump service , heat pump installation, heat pump maintenance, climate, temperature, auxiliary equipment, technology, size and control system.

How Does A Heat Pump System Works In Heating Mode?

Heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed. The evaporator becomes the condenser and the condenser becomes the evaporator. What this means, hot air will be coming out of the evaporator while cold air coming from the condenser. The science behind this process is to place the cold refrigerant in the conditioned space for heat absorption. In other words, heat is absorbed in the outdoor unit by cold liquid refrigerant flowing through the condenser coil.

The heat absorbed by the cold refrigerant gas enters the compressor to compress turning it to high pressure, high-temperature gas. The hot gas changes the state in the evaporator by giving up its heat due to cold air passing over the coil. The warm liquid travels back to the outdoor unit, which gets the meter into the condenser coil for another cycle.

How Does A Heat Pump System Works In Cooling Mode?

When the system is in the cooling mode operates in the same principle as an air conditioner. During this process, the evaporator will absorb heat from the conditioned space and replacing it with a colder temperature. This heat absorbs by the refrigerant will be taking to the outdoor unit and release through the process of condensation. 

A heat pump system won’t last forever and will need  heat pump repair or heat pump service at some point. Therefore, customers should be prepared to have their heat pump repair or heat pump service whenever needed. With our heat pump installers in Surrey, we have many years of experience in a wide range of heat pumps in Surrey. However, the manufacturer recommends you should Surrey  heat pump service or heat pump maintenance system yearly in Abbotsford. Therefore, doing so will extend the life of your equipment.
