Just had Insulation Gurus put new blown-in cellulose insulation in my attic (all the old insulation had been removed... months earlier by another company so new HVAC ducting could be installed up there). Jacob was very helpful and responsive in preparing the quote and answering questions. And Brian and his crew did a friendly thorough job with the actual insulation (vacuuming beforehand, air-sealing cracks, baffling soffit vents, and getting the new cellulose layer nice & even).read more

Outstanding service. I needed service a sap to get air conditioner working and new Nest Thermostat installed. Contracor... came out and checked the AC, corrected our incorrect Nest assembly and installed it so that it works. He was fast and very friendly, just couldn't have been nicer and more accommodating. He also called to say due to traffic he would be 20 minutes delayed, which was really considerate.read more

Perhaps a bit more expensive than others, but absolutely worth the cost. We had Sandium install two systems in our... two-storey house. The attention to detail in planning the design, the workmanship, communication and final result are all top-notch. Strongly recommended.read more

Tyler was our first point of in person contact with this company and we love him, just ask my dogs who get super... excited to see him when he comes.We had a big job to do and decided to start with the split system in our Great room. Unfortunately we couldn't find a solution to add the extension into the existing system. After much discussion the unit Tyler came up with is excellent. Our very large 600 square feet room with gable ceilings and full summer sun from dawn to dusk stayed wonderfully cool over this really hot summer we just had. We are looking forward to putting the heating side of this unit to work this winter.We were so impressed with the quality of work that we have now scheduled the second part and much larger job of replacing the duct work and current furnace with a furnace air condition for the rest of the house.The actual people who did the installation we very efficient and polite. Did a great job of installing everything and taking their mess away. Cleaning my yard up where they put the unit was excellent. Can't say enough great things about these guys!read more
