Homeowners Benefit From Sealing And Insulating HVAC Ductwork

hvac

Most Bay Area homeowners don’t give their HVAC ductwork a second thought, but you should considering it’s the major component for delivering conditioned air to the interior of your home. There are many things that can impact air quality and the efficiency of your heating and cooling system that have to do with ductwork. Poor connections, holes, leaks, cracks – any and all of these things lead to not only wasted power, but also an uncomfortable home and poor indoor air quality, not to mention higher energy costs. Sealing and insulating the ductwork on your HVAC system has many benefits!

Sealing ductwork will ensure that you don’t lose 20% to 30% of the conditioned air that moves through the ducts. Essentially you use less power, which means your A/C system will run less frequently while you enjoy a comfortable home and lower utility costs. In many older homes, ducts are made of galvanized steel, which doesn’t have insulation properties at all. Moisture can impact ducts, and depending on where they’re located (attic, basement, etc.), temperatures affect ducts, which ultimately means it affects the temperature inside your home when the areas in which ducts are located aren’t climate controlled.

Insulating HVAC Ductwork in Your Home

As any Bay Area homeowner knows, electricity or power rates rarely decrease and continue to go up. If you live in a newer home, insulation may not be necessary. However, older homes using galvanized steel are a different matter, but there are several options for optimizing energy efficiency as well as comfort and money savings. Some of these include:

  • Traditional foil-backed fiberglass insulation, available in flexible or rigid options and thicknesses that vary
  • Double-wrapped foil bubble wrap, which is cost effective, although perhaps not as durable or effective as fiberglass
  • Galvanized steel used in conjunction with flexible ducts, a great solution whether you’re retrofitting an older HVAC duct system in an older home or building a new home

Another option is flexible or “flex” ducts, manufactured of metal wire coil and covered with flexible plastic. This type of duct performs exceptionally well when it comes to preventing moisture, which can result in corrosion; however, flex ducts are more susceptible to breaks and are less durable.

As you can see, there are several solutions whether you live in an older home in San Francisco or a modern home. Our trained and dedicated Bay Area HVAC technicians can assist you in choosing the material that’s most suitable for your situation, helping you enjoy a comfortable, energy efficient home and improved indoor air quality.
