Review a pro"The sales person, Sam was very through in his presentation and very detailed.. They were able to work with me on a date and showed up as scheduled . The installers were communicative and very neat. They even finished earlier in the day by bringing more help in as I had an unexpected appointment arise. I was shown pictures of the pre and post insulation to verify what was done. I would recommend them ! "

"Project: A damper needed to be installed between the furnace and one duct line leading from it. In order to make sure all registers fed by the duct line were controlled by the damper, it had to be positioned as high upstream as possible. The job was complicated by an unclear vision that this should have been the original plan. This was not entirely due to the technicians. The cost of the job was calculated based upon breaking into the ceiling and accessing a substantial amount of duct. After about 5 ft of ceiling was exposed, the owner realized that any dampers installed in the exposed duct would be too far downstream to control nearby upstream registers. The job was re-purposed at that point, with the help of a more experienced technician than the one who designed the original job. A small section of the ceiling much closer to the furnace was opened up, and a damper--designed and constructed by the experienced technician--was installed through a slit made in the duct. The damper could be controlled from the outside by a lever, and would be able to determine heat flow to the registers that had been providing too much heat to the affected bedroom. HVAC Guru reduced the job cost by 11.5% to reflect the reduction in labor from the original invoice. The technicians were courteous, responsive and professional. Administrative personnel were courteous, responsive and professional. Some detailing for the damper control, and testing under real conditions (winter weather) are all that remain for the experience to be considered completed."

"Salesman was on-time & prepared. The scheduled work was completed on schedule. The insulation had an immediate impact on our indoor temperatures. Our only disappointment was the visible and pervasive damage to the interior walls from the tool that forces-in the insulation."

Insulation is the material which helps keep your home warm or cool depending on the season. It comes in a variety of materials, including fiberglass, cellulose, and foam and can be found in walls, under floors, in attics, and more.
One of the most common types of insulation you'll find in attics is blown-in insulation. It offers numerous advantages over other types of insulation. It is more airtight than rolled batting. It's smaller so it can get into tiny cracks and crevices to prevent air from leaking through the ceiling to the attic. It can fill in around beams, pipes, and uniquely shaped objects. Finally, it is moisture-resistant, helping to prevent mold, odor, and rot.
Even if you already have insulation in your attic, it may have settle over time, losing R-value. So if you're looking to insulate a space or you think you may need to upgrade and add more insulation, be sure to call in a professional to get the job done right the first time.
