Variable Refrigerant Flow Installation
A VRF system is a single refrigerant circuit that connects many indoor units to one outdoor unit. This application is a specialty part of our trade that takes a true professional to install correctly. We install several brands of vrf units like Lg, Mitsubishi, and Samsung. As we install your system we take all the precautions to make sure it is in perfect working order for the life of the system. We Specialize in Variable Refrigerant Flow System Installation. There are four major brands Daikin, Lg, Samsung, Mitsubishi. Each has their advantages and different prices.
This system is only for the customers looking to have their hvac equipment reach the highest peaks of hvac technology.
Mitsubishi Variable Refrigerant Flow Installation
469-887-4822
City Multi Variable Refrigerant Flow System has a two pipe system. This is the top tier of technology in the hvac industry. There are two models of systems to choose from see more about each below.
R2 Series
The R2 series is a heat recovery system that is powered by inverter technology. This feature allows the system to run a true variable speed system. That means is can run cooling in one conditioned area and heat the room next to you on the same systems at the same time. This creates great savings on energy and increases the efficiency of the unit There air options for air or water source heat pumps. Many ventilation and control options can be installed to work with the city multi VRF. It also works well with the TRANE/Mitsubishi HVRF that takes advantage of chilled water as a medium.
High Efficiency Model
78% Improved heating capacity down to -13 degrees Fahrenheit.
Ultra-quiet noise levels. Improved fan and compressor design. This reduces noise output with decibel levels as low as 55 dB(A).
Hyper Heating H2i Model
H2i (Hyper Heating) technology has improved its already industry leading heating system.
Y Series
Mitsubishi Y series can hook up to maximum of 50 air handlers. Giving you more building design options. It has a shape that is built to fit into tight locations. The design delivers quiet operation, intelligent energy usage, improved heating performance and less refrigerant volume in the system to operate.
Continues to provide up to 75% heating capacity down to temperatures as low as -13 Fahrenheit.
Energy Efficiency has improved from prior models.
Trade Mark HexiCoil Condenser Coil Technology guarantees the best heat transfer and water channeling capabilities.
Hyper-heating INVERTER® (H2i®) technology provides heating performance in cold climates, delivering up to 70% heating capacity at temperatures as low as -22°F and continuous operation down to -31°F .
Available in 6, 8 and 10-ton single modules, along with 12, 16 and 20-ton twinned modules.
Quality Hvac Systems can assist you with the design all the way through the installation process and continue to service your air conditioning and heating equipment to extend the years of comfort and reliability.

Available from 6 to 42 tons, with a choice of three-phase 208-230V or 460V-480V, or 575V (Canada only) electrical power as heat recovery/heat pump outdoor units with that provide continuous operation down to -22˚F.
Multi V Water 5
LG Multi V Water 5 systems permit synchronous cooling and heating in different zones at the same time. Units are available from 6 tons to 48 tons.
Multi V Water IV Heat Recovery
LG Multi V Water IV Heat Recovery systems permit synchronous cooling and heating in different zones at the same time. Units are available from 6 tons to 48 tons.
Samsung DVM S2 Variable Refrigerant Flow (VRF) HVAC systems
Samsung Variable Refrigerant Flow Systems is another High End Equipment Line.
AI Technology
Wide operating range
DVM S2 systems are designed to operate from 122°F (50°C) ambient to as low as -22°F (-30°C).
Ultimate Zoning Control
Samsung DVM S2 systems will allow the best temperature control in several different areas at the same time. It will also allow cooling on one air handler and heating on another with the same condenser.
10 types of air handler types with capacities ranging from 5,000 btu to 96,000 btu.

Daikin VRV Multi Split Type Air Conditioners
Daikin started in this part of the industry 42 years ago and trademarked the VRV system. The Daikin advantage is energy savings operation, individual control, adaptable design and flexible layout. See some the Daikin models and the highlights for each below.
H Series VRV Heat Pump
R Series VRV Heat Recovery
Energy Savings
Continues to run during defrost mode. limiting downtime in heating mode.
IP55 Sealed Electrical Box
Design Flexability
Long Refrigerant Lines up to 1000 meters
Automatic Refrigerant Charging
Reliability- Extended Temperature Operation
