I requested a quote from Alpha a little while back and was told that the installation would be straightforward and a 'good deal'. When i received the quote, i was shocked that the pricing was 60-70%+ or more higher than market value of the units plus a reasonable install fee, so of course I let it go. I was continually contacted to take up the offer, but I ignored. When i initially submitted this review, i was immediately harassed, phone called repeatedly about this feedback, basically telling me / threatening me to remove the feedback. The owner is a charlatan looking to take people for a ride and is also dishonest. Be wary.

Advanced Technologies in VRV/VRF Systems

VRV/VRF Systems are equipped with advanced technologies that make them highly efficient and reliable. One of the most significant technologies used in these systems is the variable refrigerant flow (VRF) system.

VRF System

A VRF system is a type of HVAC system that uses refrigerant to provide heating and cooling to different areas or zones in a building. It uses a network of indoor and outdoor units to deliver air to different zones autonomously, allowing for precise temperature control.

One of the main advantages of VRF systems is their energy efficiency. Unlike traditional HVAC systems that use a single large unit to provide heating and cooling, VRF systems use multiple smaller units to deliver air to individual zones. This allows the system to adjust its output according to the specific needs of each zone, reducing energy waste and improving overall performance.

Precise Temperature Control

VRF systems also offer precise temperature control, allowing each zone to have its own temperature setting. This means that occupants can adjust the temperature of their own space according to their preferences, providing a more personalized and comfortable environment.

Another advanced technology used in VRV/VRF Systems is the use of inverter compressors. Inverter compressors are able to adjust the speed of the compressor according to the demand for cooling or heating. This results in better energy efficiency and reduced wear and tear on the system, leading to longer lifespan and lower maintenance costs.

Other Innovative Features

Another innovative feature found in modern VRV/VRF systems is the use of sensors and controls that can detect occupancy and adjust the system accordingly. This helps to reduce energy use in unoccupied areas and maintain optimal comfort levels in occupied areas.

Other features may include self-cleaning filters that reduce the need for maintenance, and wireless controls that allow for easy and convenient adjustment of the system.
