The Retrofit Era

We have you covered.

The heating, ventilation and air conditioning (HVAC) system play a critical role in the retrofit of a building.

As the need for cooling in buildings grows and the climate change we are now experiencing becomes more pronounced, not all properties have an existing system that meets the needs of the occupants.

While investing in a new system to meet cooling requirements is a major investment, there are opportunities to improve air quality, and cooling capacity and reduce energy consumption. Among the various energy efficiency measures and system types, variable refrigerant flow heat pumps have experienced rapid growth in most of the retrofit landscape.

At Comfort Quality Services, we have the best solution when it comes to retrofit systems. Working with Daikin technology, number one in the HVAC industry, bipolar ionization systems, and support tools such as our Command Center, gives us a 360° scope to ensure operational savings from the moment of implementation.

VRV systems perform better than traditional technologies due to the better isolation of zone air with VRV system operation versus the mixing of return air from conditioned zones with warmer air from unconditioned zones in the plenum during widely used RTU systems. In addition, systems with Daikin VRV technology offer an intelligent control solution to avoid waste and give insight into performance.

When performing a Retrofit, the energy savings of a VRV system compared to a traditional RTU system for the cooling season are estimated to be approximately over 25%, 35%, and 45% at 100%, 75%, and 50% load conditions, respectively. Even the COP is higher for a VRV system operating at part load compared to RTU units operating at part load.

During the design phase, our engineering team focuses on analyzing current consumptions, and therefore the cooling load is calculated taking into account the maximum capacity of an installation. In the construction phase, most systems are selected with safety and future scalability in mind; however, in normal operation, a system will only need to operate at 50% to 75% load; studies with real-time data analysis indicated that the VRV system operates most efficiently when all indoor units are actively cooling and the compressor is operating at part-load conditions.

For retrofitting projects considering life cycle cost, feasibility, and low OPEX cost, makes VRV stand out among other technologies, adding an intelligent control system gives the customer the best solution to take care of their business operating costs. 


New Technology

Not only do retrofitted systems operate more consistently, but they also operate more efficiently and independently. This adds to energy savings, as mentioned, but it also decreases to costs of maintenance and service because the new part will be more dependable.

Faster ROI

Retrofitting equipment is much cheaper than investing in a whole commercial HVAC replacement.

Depending on your existing HVAC system, ROI can be seen from month 12 onwards.


Some utility companies will offer rebates to businesses that get a retrofit. So before you get started, have a talk with your utility company. If they offer rebates, it will allow you to see a faster return on your investment.

Improved Comfort

A retrofitted HVAC system will operate with more consistency than an older or poorly maintained system. This consistency leads to more control over the temperature in humidity, resulting in improved comfort for occupants.

Energy Savings

Retrofitting HVAC equipment is one of the quickest ways to solve chronic problems with high energy consumption. On average, small offices and retail establishments reduce energy consumption by 35% when retrofitting HVAC systems and equipment. In cold weather climates, this number can jump to as high as 40%.

Increased HVAC Lifespan

Every HVAC unit has an expected service life that ranges anywhere between 10-20 years.

Replacing a defective part gives your HVAC equipment new life. In fact, sometimes you can even extend the life of your system by several years, spending far less money than a whole system replacement.
