There are many options when it comes to choosing the right air-condition system for your commercial business, but there one system that offers the highest efficiency and increased control-ability. This system is called variable refrigerant flow, or VRF and was recently introduced to the United States. VRF is a configuration of an air-condition system that consists of one outdoor condensing unit and multiple indoor units. The term “variable refrigerant flow” describes that system’s ability to control the amount of refrigerant that flows to the multiple indoor evaporator units. This allows for individualized comfort control as well as simultaneous heating and cooling in different zones.
Daikin Industries in Japan designed a VRF system in 1982 known as “variable refrigerant volume,” or VRV. The VRV technology allows for individual climate control in differing zones by circulating only the minimum amount of refrigerant needed at that time. The Daikin VRV system has endless benefits: it minimizes energy consumption, has a design that can be adapted to the local environment, has a flexible layout, and allows for individual control within the building.
VRF and VRV systems are complex, engineered systems that use a multipart refrigerant and oil control circuitry. They can be used for cooling only, heat pumping, or heat recovery. There are two basic types of VRF systems on heat pump models – heat pump systems and energy-recovery:
Heat pump systems allow for heating or cooling in all indoor units but not simultaneously. The units either cool or heat. These systems are applied successfully to open spaces, retail stores, cellular office or any other space that requires heating and cooling in the same operational timeframe.
Energy-recovery systems are known as VRF-HR and can operate simultaneously in heating and/or cooling mode. This allows the heat removed from a cooled space to be used instead of rejected to the outdoor environment as in traditional heat pump systems. The enhanced features and design of VRF-HR systems has a great potential to produce significant energy savings. Each manufacturer has a proprietary design with unique valve arrangements. VRF-HR systems are best used in buildings where some of the spaces need to be cooled and other spaces need to be heated at the same time, such as medium to large sized buildings with large core space or in spaces on the north and south sides of the building.
Several advantages of a VRF system for your building’s HVAC needs include:
User Comfort: the VRF system can respond to individual fluctuations in space load conditions. Each user can set the temperature in their space to their own comfort level versus one control for a variety of spaces in the traditional air condition system. The individuality of the VRF system also allows for separate billing in the case of multiple tenants within one commercial building.
Design Flexibility: A single outdoor condensing unit can be connected to several different types of indoor units of varying capacity. Current systems allow for up to 48 indoor units to be connected to one condensing unit.
Flexible Installation: VRF systems accommodate installation and commissioning on a floor by floor basis and they are lightweight and offer space-saving features.
Energy Efficiency: Testing has indicated that VRF technology can reduce energy consumption by as much as 30 to 40% per year compared to a traditional compressor and it offers high coefficient of performance (COP). This system also minimizes ductwork, or completely eliminates it in some cases, which can reduce duct losses of airflow.
The news about environmental pollutants, disasters and the greenhouse effect is increasing in frequency, but so is the rate of innovation with energy efficient technology. The use of clean and efficient energy systems can provide a solution to the impactful issue of environmental pollutants, and save home and business owners on energy costs. At the top of energy efficient technology is solar PV panels. Switching to solar energy power as an alternative energy solution for our every day needs can dramatically offset the negatives effects of fossil fuels, create independence from utility companies, and lower energy costs.
In addition to solar power, there are several more clean energy technologies that are helping the environment and saving home and business owners on energy costs:
Ultra Efficient Heat Pump Systems
The next generation of heat pump systems can reduce energy consumption as much as 30 – 45%. There will be several options for owners to chose from including fuel-fired multi-function residential heat pump, low-cost gas heat pump, natural gas heat pump and air conditioner.
High tech thermostats automatically adjust room temperatures based on the individual’s lifestyle. The owner simply enables the thermostat’s settings to accommodate their comfort level and schedule, and high-tech sensors and algorithms will automatically adjust temperatures per those settings.

Preventative maintenance for your building’s HVAC system is a smart investment for both your system equipment and for your building occupants. HVAC systems are the lifeblood of any building and without it, a building would be uninhabitable. Action Air Conditioning, Heating and Solar can set up a strong preventative and predictive HVAC maintenance program ensuring that your system will be properly maintained.
Maintenance won’t be expensive compared to the costs that will occur if the system degrades or fails before the end of its life-cycle. In fact, proper maintenance can cost significantly less over the life of the equipment when compared to changing out the equipment at more frequent intervals. Predictive maintenance will assist you even more in avoiding unforeseen declines or failures in system performance. Installing up-to-date equipment will add a deeper level of controllability and prediction to prevent a system failure.
Action Air can provide smart thermostats that are controlled from a computer, either onsite or remotely, with all of a building’s thermostats controlled by that one computer. Using smart thermostats can reduce operating and repair costs in several ways; programming the thermostats to varying heating and cooling per the building’s occupancy and the seasons can optimize the system’s performance without unnecessary expense. Smart thermostats can also inform the operator of any changes in the system’s performance that might indicate a need for preventative maintenance to avoid early decline of equipment. Additionally, having multiple thermostats controlled from one computer saves time and electricity in the management of the system. An operator can oversee the entire system and monitor the performance of each one individually.
Action Air also offers software that works with sensors tied to HVAC units that will indicate when a system will fail. Catching a failure before it happens allows for the required maintenance to be performed on a schedule that benefits the building owner as well as the occupants. Scheduled maintenance and repair will almost always cost less than an emergency repair, especially in terms of interrupted productivity of the workers utilizing the building.

Reports have shown that an estimated 75% of 90 million commercial rooftop HVAC units do not run efficiently.
This is a staggering report as energy costs are a primary concern for both business owners and homeowners. Upgrading your building’s heating, ventilation and air conditioning systems can ensure that your building does not fall within this overwhelming majority. If your HVAC system is more than 10 years old, now is a good time to assess whether your system needs to be replaced before the system fails. This also give you the opportunity to research your options on what type of system would be the most efficient for your building and fits within your budget.
With proper maintenance, a building’s HVAC systems can last a long time, but outdoor and rooftop units can be especially vulnerable to damage and neglect. Rooftop units require specific care to guard against damage caused by dust, debris, and weather related events such as hail. A damaged air conditioning unit can increase the cost of operating and maintaining the system and will function less efficiently or even worse fail completely.Routine maintenance on your current system will catch any major damage or wear on your equipment so that you can do necessary replacements before complete system malfunction.
Failure to replace your aging HVAC equipment can also result in loss of temperature control, poor air quality and excessive dust. These things can lead to occupant discomfort and possible health problems for both the workers in a business or the homeowner and their family. A retrofit can sometimes help regain control of the indoor environment and a full upgrade will guarantee that your health won’t be harmed by a decrease in air quality.
Replacing your HVAC system with a new one will also ensure that you are using the most efficient equipment for your space. Older models don’t run as efficiently as the newest technology and with Energy Star equipment, you can save significant money on your utility bills both in the short and long term.

Using Energy Star certified equipment will also contribute to an eco-friendly HVAC system.
Call our experts today to get started on your eco-friendly HVAC installation or upgrade! Action Air’s NATE-certified technicians are trained to install, repair, and service all HVAC systems per the LEED and CALGreen guidelines.
LEED and CalGreen Can Guide the Design of a Green HVAC System
An eco-friendly HVAC contractor will be able to guide you through the process of achieving LEED certification for your building. LEED stands for “Leadership in Energy and Environmental Design” and was created in 1998 by the U.S. Green Building Council. The LEED certification program promotes environmentally friendly buildings that can lower energy bills, improve indoor comfort, and provide a healthier work environment.
The CALGreen Building Code includes stringent codes that have mandatory and voluntary components for meeting certain sustainability and ecological standards for buildings and renovations in California. These codes pertain to everything from water efficiency and building materials to indoor air quality. CALGreen and LEED have several areas that overlap and your highly trained HVAC contractor will help you navigate the documentation requirements for both.
Replacing your outdated, inefficient HVAC system with a new one can seem like an overwhelming project, but is well worth the money you will save on your utility bill and the increased comfort of your indoor space.
If your home’s HVAC system is more than 10 years old, or you are making frequent repairs to your equipment, now is the time to contact a professional who can assess the system’s performance and to determine what type of upgrade will provide a solution for your needs.
Before making a purchase decision, there are a few things to consider.
First, check your current system to make sure it has a correctly programmed thermostat, well-sealed ductwork, and sufficient insulation. If these items are missing from your HVAC system, they are most likely the source of your problems. Secondly, be prepared to replace all your HVAC equipment at the same time. Often, older parts won’t work properly with newer ones. It might seem like a good plan to save money by only replacing some of the equipment, but a mismatched system can severely decrease the energy efficiency and performance that you would expect with a complete new system. It is also a good idea to tune up your home or business by making energy improvements that will reduce operating costs and help your HVAC system operate at peak performance. Check these places in your home where air might be escaping to the outdoor environment:
Covering these holes can increase your system’s efficiency and increase your comfort level.
Once you have contacted your HVAC contractor, they will come to your home or business to assess your current heating and air conditioning system and discuss any problems or discomfort you have in your building. There are a few guidelines that an expert HVAC contractor should follow to make sure that your upgraded system works at peak performance:
Ask your contractor to perform a detailed load calculation to ensure that your new HVAC system is the right size for your specific home or business. A system that is too small will not deliver adequate heating or cooling in extreme weather, and one that is too large will cost more and provide insufficient temperature and humidity control.
Your contractor should install ductwork that does not leak. According to Energy Star, an estimated 15% energy loss can be attributed to leaky ductwork. That is a big loss, especially when your new system should be more energy efficient than your old one.
Ask your contractor about correct airflow and refrigerant levels (if applicable) for your specific system. Incorrect airflow and refrigerant can both result in reduced cooling capability and higher energy costs.
Hiring a highly qualified contractor like Action Air might cost more upfront, but it will save you money in the long run. Poor installation can result in higher energy costs, shorter lifespan of equipment from inefficient performance, early system failure, and reduced personal comfort.
