Providing the professional services you need at affordable prices. Locally owned and operated since 1993.
Welcome

To HVAC Design and Support LLC. we are the professionals you should have had at your side on that last Residential or Light Commercial project! We are at your service specializing in providing a competitive bid package for Custom Designed High Performance Residential HVAC Systems.

Design-Build Package 

In addition to the benefit of an efficient pre-designed HVAC Systems CAD layout, in which the client or representative of the client is involved, the need to address answers to relative questions about allergies, VOC's and Ventilation are a vital component. The search for an HVAC Contractor can be undertaken competitively and completed prior to the commencement of construction. This advantage enables the appointed contractor to schedule your project, order materials, and equipment on time and in advance, ensuring the HVAC phase of the project is completed on schedule or before.

HVAC  Fact Sheet

Accurate Load Calculations are the key to energy efficiency and a comfortable home environment.  







Architectural and Mechanical design collaboration at the project development stage produce an immeasurable benefit in terms of eliminating potential cost overruns. This is achieved by the prevention of obstructions arising during installation of ductwork through framing designs, duct sizing and problems with equipment locations, airflow and accessibility. Utilizing pre-designed custom HVAC systems and discarding the cumbersome  Bid- Design- Build method will ensure that you understand what you need to know and receive value for your investment in your home.

Although IRC M1503.4 has challenged builders, it is rooted in safety. Since modern homes are built with far less air
leakage than they have in the past, the operation of a high-cfm  Kitchen Exhaust Hood can cause a negative pressure inside the
home. This can result in back-drafts from fuel-burning appliances, which can lead to unsafe levels of carbon monoxide and
other toxins inside the home. Visit the Compliance tab above for additional information on Exhaust Systems + Makeup Air

The Carrier Infinity System plays a major role in meeting the technological requirements of today's fast-paced professionals. The Infinity Touch Control  is available with and without Wi-Fi connectivity capability. The Infinity System provides Seasonal Energy Efficiency Ratio of up to  21 S.E.E.R.  


Both the Wi-Fi and non-Wi-Fi versions are designed for single or multi-zone  applications. Complete integration of temperature, humidity, and ventilation in every season. In addition to environmental safety these systems are 30 to 40% more efficient than the standard heating and cooling systems, thereby combining excellence in efficiency and environmental safety.

Energy Star, LEED and many permit offices require that after the residential HVAC designer has completed the ACCA Manual J
load calculation to determine the heating and cooling needs of the home, then the designer needs to size the physical HVAC equipment based on Manual S and the manufacturer OEM data for the home's specific design conditions. The Air Distribution







Few architectural firms plan for the structural elements in residential projects that allow for duct placement in the correct locations along with returns for the equipment as well as suitable mechanical room location and floor space. It's no longer acceptable to throw up a bunch of beams or joists (LVL's) and a minimum height finished basement, and then engage an HVAC contractor to show up and figure it out! That alone can have disastrous consequences forcing changes in design that can result in having a detrimental effect on the HVAC system as well as delaying the project..
