The benefits of energy saving and cost saving solutions available in both commercial and residential products from Daikin ,Trane and other brands of HVAC has been the latest in developments in HVAC products.
The reason ?
Everyone knows and understands by now that as a world we cannot afford to ignore the effects of using large quantities of natural resources on the environment. And remember, your air conditioning unit works on electricity, and your boiler on gas or oil.
Therefore products now include a host of features to increase its efficiency.
Firstly, there is the SEER rating . The higher the SEER rating, means the ratio between the BYU output to energy input. As of January 2006, all residential air conditioners sold in the United States must have a SEER of at least 13 So that can give you a guideline . But of course a SEER rating of 15 will be even more efficient.
Let’s take an example
The annual cost of electric power (@12C per kw hr )consumed by a 72,000 BTU/h (6 ton) air conditioning unit operating for 1000 hours per year with a SEER rating of 10 would be $864 while with the same unit at 15 SEER the cost would plummet to $576
Another feature to look into are inverter air conditioning units which can save you upto 30% on energy costs. An inverter however acts like a throttle of a car that slowly ramps up your unit and prevents the surge in your power consumption. No more blinking lights when you start up your unit, and no more noise.
And last but not least there is the VRV system. To date Daikin are the only brand who supply the VRV system- a sophisticated system that works on a Variable Speed control, allowing the end user to switch the unit on and off at whim, and heats and cools the space according to specific needs. This is a huge money saver for building with multiple users and is therefore a must for all our New York clients.
All in all when you next want to buy equipment -know that it is better to pay more for that efficiency to save you on running costs and energy costs per year.
But what can you do about your old gas or energy guzzling equipment?
1. Have it evaluated
According to Energystar, if your equipment is more than ten years old, have it evaluated. If it is not performing efficiently, consider replacing it with an energy efficient product. This will also help you save on labor and running costs as well as reducing the carbon footprint, contributing to the Green building concern.
2. Retrocommision it
check the quality of the installation of your equipment and consider your ductwork, Making sure that your equipment is properly installed can improve system efficiency by up to 30 percent —saving you on your utility bills and possibly lengthening the equipment’s life.Checking that your ductwork is well insulated and is not leaking can also contribute to energy waste as air leaks out .

As far as we can see, the HVAC industry of the future will be driven by “sustainability, globalization, workforce, and technology.” And as a result, we as air conditioning engineers and contractors, will be taking on new resposibilities in energy management, green building, sustainability , and Indoor Air Quality.
