What constitutes a 'good' design?


  1. The right sized equipment is selected for the project. Most commonly oversized equipment is installed which is less energy efficient than 'right-sized' equipment.

  2. Effective distribution of air or hot water. Poor distribution will create noisy air delivery, hot or cool areas of the house and hinders the equipment energy efficiency with long run-times.

  3. Cost effective to install. Elaborate over-designed systems may work well but is a waste of material and labour costs.

  4. Considers occupants health and lifestyles. Allergies, sensitivities, recreational pastimes in the dwelling must be prior to any design.

  5. Easily serviceable and equipment longevity. Operation should not hinder the life-expectancy of the equipment and contractor’s should be able to easily and effectively service the systems.


Why invest in an HVAC Design from a Certified Design Expert?

Comfort Guarantee
Proven design parameters guarantee effective distribution of heating or cooling during all seasons.

Efficiency Optimization
Ensuring the optimum sized heating & cooling equipment is selected to maximise energy efficiency.

Minimized Contractor Installation Costs
Reduced installation costs will enable a 'net-benefit' or immediate 'return-on-investment' and allow apples-to-apples comparisons between contractors.

Designs Tailored to Meet Your Expectations
Consistently seeking owner and contractor input to ensure all expectations are exceeded.

On-Site Consulting & Support Services
Personal onsite service is provided for thorough troubleshooting of challenging projects.
