New Construction

Why not get your HVAC system right from the beginning?

For the greatest possible comfort in a new home, planning the HVAC (Heating, Ventilating, and Air Conditioning) system is essential and smart.
This system includes central air conditioners, heat pumps, furnaces, boilers, rooftopunits, chillers, and packaged systems, carefully designed to fit right into your home.

While a system that’s too small will cause obvious problems — including rooms that won’t stay warm or cool — putting in heating and air conditioning equipment that’s oversized is just as irresponsible. Planning the location and size, is very important , and our highly qualified team will help you with that too!

Why overhaul is important?

A very important part of preventive maintenance is overhaul. Overhauls provide the ability to disassemble the parts and check for wear and abnormalities. Consultation with Daikin service engineer helps users to determine the appropriate interval for repairments.


Replacing fan bearings

Replace the fan bearings, when you experience an abnormal noise and vibration. Air conditioners will operate all year round - not just during the cooling and heating season, but also during the transitional period provided for ventilation. Abnormal noise and vibration can indicate the need to replace the fan bearings. Do not wait until failure occurs during the peak season, please contact Daikin today to check your system.

Cleaning heat exchanges

Air conditioners collect dust when working. Dust accumulates in various places inside the air conditioner. This may become a cause of serious damage to equipment and large faults. Cardboard dust not only reduces the efficiency of the heat exchanger, but also reduces amount of air flow that affects the overall performance and operation of your unit. Dust also leads to forming mold odors, water leaks and equipment failures.

What is a Preventative Maintenance Program (PMP)?

Our Preventative Maintenance Program is a bi-annual, complete system check that ensures your heating and air conditioning system is working correctly and efficiently through scheduled inspections and maintenance. Just like with your car, your HVAC equipment needs regular maintenance to keep it running reliably.
