”"Our attic used to feel like an oven and it was pushing 140°F up there every summer afternoon. After the radiant barrier attic installation, the upstairs bedrooms stay noticeably cooler and our AC doesn't run nearly as much. Best energy-efficiency upgrade we've made to the house."
Radiant BarrierAttic
”"Energy efficient attic insulation was on our list for years, so we finally pulled the trigger on a radiant barrier installation and it's already paying off. Lower cooling bills, less attic heat radiating into the living room ceiling, and a fast, clean install."
Radiant BarrierAttic
”"We kept losing heated air before it ever reached the vents because the ducts ran through an uninsulated crawl space. Insulating the ductwork down there made a huge difference this winter with warmer rooms and a noticeably lower heating bill."
Radiant BarrierDuct
”"Our ductwork runs straight through a superheated attic, so wrapping it with a radiant barrier duct wrap made an immediate difference. The air coming out of the vents is noticeably colder now instead of losing all that cool air on the way to the room."
Radiant BarrierDuct
”"The duct damper installation solved a problem we'd been living with for years with uneven room temperatures because the upstairs got way more airflow than downstairs. Simple fix, huge improvement in comfort."
Duct Damper
”"We'd tried closing vents in other rooms to force more airflow to our home office with no luck. The duct booster for weak airflow solved it in one visit with steady, strong airflow every time the system runs."
Duct Booster
”"Our solar attic fan has made a bigger difference than I expected. The attic no longer bakes all day, our shingles should last longer, and the upstairs rooms are noticeably cooler in the evening."
Attic Fan
”"We looked into whole-house attic ventilation for a while before finally installing a powered attic ventilator. It runs quietly, pulls the hot air out fast, and our energy bills have gone down since."
Attic Fan
”"Looking for a water-saving shower head that didn't feel like a weak trickle, and this delivered. High efficiency shower head, strong flow, and a visible drop in our monthly water bill within weeks."
