Heating, ventilation, and air conditioning (HVAC) as a branch of mechanical engineering strives to make the indoor environment conducive for human habitation in terms of ensuring an abundant supply of fresh air. To achieve this, HVAC engineering focuses on air quality in terms of relative humidity present in the air, air flow rate and ambient temperatures. HVAC uses the principles of thermal physics and heat flow.

Our engineers have wealth of knowledge and experience for designing the best, economical HVAC systems and installing these systems in all manner of buildings ranging from small family rooms to skyscrapers.

Given the fact that HVAC systems consume a lot of energy, our engineers design them as efficient as possible to reduce long-term running cost. These systems run on multiple sources of fuel. Ventilation and air conditioning systems use electrical power, while space heating uses both electrical energy and energy from fossil fuel. The most common fossil fuel in use in the United States is natural gas such as propane.

In a situation where natural gas is not available on site, our engineers will advise on the most appropriate alternative since for this case space heating will depend purely on electrical energy. The common alternative is usually high energy-saving HVAC systems that have high initial capital investment but low maintenance and energy cost.

Site survey in HVAC engineering is the most important step our engineers consider before the actual installation. This is usually done to calculate the energy (load) requirement depending these on two factors.

• Site location, different regions have different prevailing climatic conditions, for example, colder environments require more heating.
• The purpose for which the building is designed for and factors like floor area, number of occupants, the material used to build.

All the above factors help our engineers to size appropriate HVAC systems so that they obtain an optimal sized unit as opposed to installing an undersized or oversized system. The optimal system will be the best in terms of providing the required service while minimizing ownership cost, operations cost as well as maintenance.

The sure way of improving the performance of HVAC systems is by having our engineers suggest the most efficient system and include computerized or automatic control systems to enhance performance. Normally the more efficient a system is the greater the initial investment cost but long-term operational cost far outweighs the added cost.

Further improvement on performance while minimizing cost can be achieved by using adjustable systems such as ventilation systems that can rather be slightly closed when a room of factory occupancy is not at maximum as well as using motor-driven equipment such as pumps whose rotational speeds can be varied to give room for speed reduction on different weather conditions.

Working with our experienced engineers, the specific needs for every project will always be analyzed and proper advice and steps are taken. Do not hesitate to contact us any time for a site visit, quotation, and advice. Best of luck during your HVAC system installation.
