Why Ductwork Design is Important to Home Comfort and Energy Savings

Duct in Attic

Ductwork might seem simple. After all, it’s just a system of pipes carrying air from your A/C to your living room, right? While that’s basically true, there can be quite a few pitfalls that should be avoided when designing ductwork.

Otherwise, your home comfort will suffer, and you might end up paying extra on your monthly cooling bill. That doesn’t sound appealing, does it?

So what are some of the potential pitfalls of ductwork design?

  • Excessive air leakage: Unfortunately, leaky ductwork is quite common. Sometimes this is due to improper sealing and insulation techniques, and sometimes it’s just a problem that develops over time. Luckily, these problems can usually be fixed with a little duct mastic or metal-backed tape.
  • Insufficient insulation – Ideally, ducts should be installed in conditioned areas of the home to reduce the need for insulation, but that’s not always possible. If ducts must run through unconditioned areas such as a garage, attic, crawl space or basement, they need to be properly insulated.
  • Unbalanced airflow – This occurs when the air coming out of your supply registers doesn’t have a clear enough path to the return grilles. This causes pressure differences to develop in your house, which can increase drafts and create hot and cold spots. Door and wall grilles can be installed to remedy problems with existing ductwork, but for new designs, including a return grille in every room that has a supply register is recommended.
  • Too many turns – To ensure central heating and A/C efficiency, duct runs should be kept as short and direct as possible. You don’t want unnecessarily long stretches of ductwork or too many twists and turns. These issues make it harder for the air handler to move air through the ducts. This not only puts a strain on your system, but it compromises your comfort and your energy budget.
  • Improper ducts – Proper airflow is hard to achieve if air is directed through wall voids or building cavities instead of well-designed air ducts. Building cavities are also hard to sufficiently seal against air leakage, and they can contain contaminants (such as mold) that you’d rather not have blowing into your family room.

AC Service Testimonials

Excellent

I had an excellent service call with Daniel today. He quickly diagnosed the problem with my ac and explained the issues, all my options, and prices. He explained everything to me such that I understood what was going on, and felt totally comfortable with the decision I made. The office staff was excellent, as well. I plan to replace my ac before year's end and will definitely purchase from Scott's. Thank you! It's so great to do business with competent, courteous, and efficient individuals.
The professionalism of the parties I spoke with and/or met spoke words. Things were explained in terms I could understand throughout the process. Even though the instillation took 2 days due to some issues, the team did their best to have my AC replaced and running by the end of day 2 and kept us comfortable in the mean time. I highly recommend this company for any AC needs…
Scots can always be counted on to keep our AC running properly with friendly, on time, professional technicians.
I had a new unit installed back in 2022 and have been having regular maintenance twice yearly since then. All has been well. Today I was scheduled for maintenance once again and my unit was taken care of, but my technician Allen pointed out that my other unit outside (not installed or maintained by Scott's) had frayed wires on the outside condenser which would soon lead to a short on that unit. He offered to get me a quote to fix that and I agreed to receiving a quote. He was able to provide the fix right away and had that taken care of in less than an hour. I really appreciated the extra attention he paid to the overall area, and that he was willing to repair something that was not installed by his company. It was his genuine concern that took precedence. I will continue to recommend this company and will most likely have them as my provider when that second unit needs replacement.
