It’s no secret that Lafayette is exploding in terms of growth. New subdivisions like Acadian Meadows and Stable View are expanding rapidly, but with all that new construction comes a need for expertly designed HVAC systems.

Contact us today for exacting, precise calculations that will keep you comfortable throughout the long cooling season of a brutal Louisiana summer.

What Are Manual Load Calculations?

If you’re new to the HVAC world or are just interested in learning more, reading about Manual J, D, and S load calculations for homes in Lafayette, LA, can feel like a different language. But don’t worry, it’s pretty easy to break down what we’re talking about.

Manual J

A Manual J load calculation measures specific variables to discover the heating and cooling demand of each of your rooms. It involves so much more than a quick measurement of square footage. Our team will look at vital factors like the following to get the clearest picture of the power required to maintain even temperature control:

  • Window placement
  • Sunlight exposure
  • Ceiling height
  • The size of your family/other residents

 

Speeding through this process can land you with an under- or oversized system. An air conditioner that’s too small, for example, will run itself to death trying to cool a home that it doesn’t have the power to support. Oversized units can also take on wear and tear from short cycling (turning off and on rapidly instead of completing a full cycle).

Manual D

Using the calculations from the Manual J work, your Manual D calculation is all about getting your ductwork properly set. All that data we took during the Manual J gets leveraged here to create an energy efficient layout that ensures your rooms get the right coverage. 

This may feel like a step you can rush through, but sloppy ductwork can lead to:

  • Higher energy bills at the end of the month.
  • Uneven cooling throughout your home.
  • An HVAC system that has to work harder to do its job.
  • Poor performance and comfort that suffers.

Manual S

Finally, once we have a full understanding of your home’s cooling and heating needs and ductwork considerations, we can move on to the equipment that makes it all happen. The Manual S calculation takes data from the Manual J calculation to pair you up with the HVAC equipment that meets your home’s efficiency and temperature requirements. Your Manual S will give you the information required to find the right models without overspending on a system that’s the wrong size.

Our Testing Services

Outside of Manual J, D, and S load calculations in Lafayette, LA, our team can also pinpoint leaks that are throwing off your home’s energy efficiency and ability to retain treated air. Blower door tests bring in specialized fans to locate gaps in your insulation and sealing. Duct blast testing is a similar process that identifies leaks in your ductwork.

Frequently Asked Questions

Do I need all three calculations to satisfy permit requirements?

Most best practices and permit offices require Manual J, D, and S calculations in Lafayette, LA, to satisfy permit requirements. Each calculation builds on the last, so getting an HVAC system set up with the proper specifications requires all three.

Can’t my HVAC contractor just estimate these calculations?

They can certainly try, but using a rough estimate without properly factoring in every variable can land you with an undersized or oversized system. Working with the certified professionals at HVAC Essentials protects you against costly mistakes.

What type of issues does an oversized HVAC system lead to?

If your air conditioner is too big you’ll have to deal with it turning on, cooling too quickly and then shutting off before it has a chance to deal with humidity correctly. Your home may be cooled, but it will still feel clammy and uncomfortable until the sizing issue is dealt with.
