"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

Yes, you should insulate your copper pipes to help regulate their temperature. Well-insulated copper pipes will be protected from freezing and can conserve energy by keeping hot water warm for longer. Foam rubber insulation tubes are the best pipe insulation to prevent freezing since they fit tightly around the pipes while still maintaining some flexibility.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Yes, including recycled denim and cellulose from natural fibers.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.
