Ductless Mini Split Heater and Air Conditioning in Tustin

ENERGY STAR certified ductless heating and cooling systems are highly efficient products that deliver warm or cool air directly into different zones in your home, instead of routing it through ducts first. During the summer, this highly efficient and versatile heat pump will fill your room or multiple zones with cool, refreshing air. During fall and winter months, it gently warms your room.

Mini splits have no ducts, so they avoid the energy losses associated with the ductwork of central forced air systems. Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic. The US Department of Energy recommends using mini-split systems as a means to reduce energy consumption and cost.

We carry the most extensive line of ductless mini split products including: American Standard, D Air, Daikin, Friedrich, Fujitsu, Mitsubishi, Panasonic, Samsung, LG, Trane, Carrier, and Toshiba. All of our installations come with a 1 year labor warranty and a 5 year manufacturer warranty.

Air Balancing & HERS Rating in Tustin

HVAC Testing, Adjusting and Air Balancing (TAB) are the three major steps used to achieve proper operation of HVAC (heating, ventilation, and air conditioning) systems. The NCI Certified Air Balance insures that all components of the HVAC system are working in harmony, at their optimum performance, providing total occupant comfort. During this process, a mechanical engineer develops specifications and a set of mechanical drawings from a mix of occupant desires, local codes, ASHRAE standards,and many years of training.

Testing, adjusting, and balancing of all HVAC systems in a new building is needed to complete the installation and to make the system perform as the designer intended. The purpose of testing, adjusting, and balancing (TAB) is to assure that an HVAC system is providing maximum occupant comfort at the lowest energy cost possible. This is extremely important in this era of rising energy costs. Most new commercial projects require a licensed air balancing report before they are able to receive a certificate of occupancy.
