"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation FAQs, answered by experts

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.
