HVAC System Design for Builders: What You Need to Know

Filed in Codes and Regulations, Education, Home Building by on April 11, 2017 4 Comments

HVACNew HVAC technologies and more stringent building code requirements have increased the importance of getting the mechanical systems designed and installed correctly.

The combination of highly efficient HVAC systems and tight duct systems and envelopes can create an unintended consequence if you aren’t sure how the two work together.

Today’s HVAC equipment is typically oversized for corresponding duct systems. This leads to inefficient circulation, faster wear and tear and higher bills for your client. It’s important that you and your HVAC contractor are on the same page before you begin construction.

Don’t leave your customers in the cold! The webinar What a Builder Needs to Know about the HVAC System Design Process, Wednesday, April 26, 2-3 p.m. ET, will examine how to avoid this costly size discrepancy by:

  • Reviewing the Air Conditioning Contractors of America (ACCA) Manuals J (Residential Load Calculations), S (Residential Equipment Selection) and D (Residential Duct Design).
  • Providing a basic understanding of what an accurate system design entails.
  • Identifying specific, discrete design parameters that can be checked to ascertain if the design process has been followed.

Join speaker Glenn Hourahan, ACCA Senior Vice President, for this engaging session and come away with a better understanding of these important systems. Register today!

  1. This is why more and more builders are turning to third party design, equipment selection and permitting. Our designs were in more than 10,000 new homes in 2016 and will be double that in 2017. High performing new construction can be wholly compromised by old-school design and sizing that too many “rule of thumb” contractors still follow today.

      Thanks, Matthew. That is precisely why NAHB is offering this webinar. Builders need to know what to tell their subs so their subs can provide the performance they are looking for.

    This should be a great informational piece for builders and HVAC contractors. I have heard builders say “I don’t need to know how to do it but I certainly want to be sure that my ac guy does!”… The better we build, the smaller the margin for error, which is exactly why we can no longer do what we’ve always done! This webinar will go a long way in helping the communication between the builder and the trade so that everyone can feel comfortable that they are getting it right!

  3. Now, if we could just get the home designers on board with the space required to properly install an HVAC system we will really have accomplished something!!
