"Tempest insulation with Fernando are going to be my go to team for any future insulation needs. I used tempest for a R44 blown in insulation. Fernando was on time for the estimate, sent me a follow up with responses to all my questions and began the work at 8 am on the dot! He and his crew were timely, professional, clean and were in and out of my place in less than a day and cleaned up everything after themselves. I would highly recommend them!"

"They came out to look and suggested that this was not an insulation problem, but a problem with the duct work for the A/C. They had recommended one of their A/C subcontractors who did an excellent job."

"Last week I had Landmark energy upgrades, do energy efficiency work at my home. The work included sealing all my duct-work in the attic as well as sealing all the spots between the living space below and blowing in additional insulation in order to bring me up to today's standards. I also had them replace all the duct work in my crawlspace and seal it as well as when they came for their initial inspection they found that my duct-work was riddled with holes and was completely uninsulated as well as being unsealed. I initially contacted Landmark after receiving notification that they were offering assorted rebates for home owners to incentivize them to do upgrades to there homes.
I was super pleased with these guys, a total of two crews worked on our home and they were both quick, professional, and explained what they would be doing in detail when they first arrived. They also did a good job cleaning up after themselves. Immediately I noticed a difference in my home after the work was finished. The HVAC system weren?t running nearly as much and the temperature in the home was absolutely more consistent. Landmark Energy Upgrades promptly handled all the paperwork required in order for me to receive my rebates making this part of the process extremely easy. I fully recommend these guys!
