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.</p></div>

Q: Can you put insulation on top of ductwork?

• <div><p>Yes, you can install insulation over ductwork, and doing so can save you money.

Q: Does condensation on windows mean poor insulation?

• <div><p>Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you&rsquo;re worried about whether or not your windows are properly insulated, have a pro assess them.</p></div>

Q: Are there any safety concerns with fiberglass?

• <div><p>Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics.

"The work was clean and the owner as well as, all of the employees were professional and friendly. The only criticism would be the failure to clean up the job site. They did haul most of the rubbish away but the employees left chunks of drywall mud and screws on the floor of the garage, empty bottles in the yard, and leftover materials, fiberglass insulation, were thrown carelessly on top of my personal belongings. Despite the messiness, I would hire this company again. ?"

"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."
