Knowledge HVAC & Refrigeration RTU (Rooftop Unit)

As a refrigeration technician in Surrey, we know that rooftop unit repair and service is extremely important to sustain the life of these systems due to the all-in-one heating and cooling system design. Buildings that cannot accommodate a furnace and coil or an air handler would have a packaged unit installed. These systems are designed with all of their parts in one outdoor unit that sits on either the roof or to the side of a building. Many RTU in Surrey come completely equipped with factory install furnaces. Heat can be produced by an integrated gas-fire furnace or electric resistance heating elements. 

These systems are completely weatherproofed since they are exposed to all kinds of weather conditions and have access doors that are designed to protect equipment electronic components. There are four main dampers that control airflow through the unit by the use of temperature sensors. These are:

  • Return Damper
  • Condition Air Damper
  • Exhaust Air Damper
  • Fresh Air Damper

Packaged units are designed with an air condition system for the hot summer climate. these systems also have four main components:

  • Condenser – This is where the high compress vapour from the compressor goes to be condensed to a high liquid refrigerant and releases the condensation heat.
  • Compressor– This is the heart of the refrigeration system, which compresses low temperature and low refrigerant vapour into a smaller volumes. The compressor pumps this vapour to the condenser where the heat is released from the refrigerant as it condenses.
  • Evaporator– this is a heat exchanging device that absorbs heat and is placed in areas where heat needs to be removed.
  • Metering Device- this component restricts the flow of liquid refrigerant to create the proper pressure drop between the b high side and low side of the air-conditioner system. 
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.

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

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!!!

Reason for Rooftop Unit Repair

If you want your packaged unit to last for a long time, you should be having it service once a year. Ideally, this would be in the springtime when you’re just starting to use it, but any time of the year is ok. People may be hesitant to spend money on maintaining their packaged system when they don’t think there is a problem, but the truth is that it will wind up saving you a lot more in the long run. Paying for regular air conditioner service will be much cheaper than having to pay for major rtu , or even to have a whole new packaged system install.
Note: Early  rooftop unit  repair  can be avoided by having a certified Abbotsford refrigeration technician installing your system. A rooftop unit repair, install and service should be done by a certified person or a commercial refrigeration technician in Surrey .
