My firm helps organizations increase profits by reducing expenses, recovering overcharges, and taking advantage of available tax incentives. We're helping employers reduce the cost of their health benefits, typically by 12 to 25%, and sometimes much more, and without necessarily changing their broker or changing their health plan provider. We don't sell insurance, we address the medical billing issue that drives the costs. We are better than any broker/agent because we build your plan from the ground up, then manage it to keep costs down. We have over a decade of experience saving our customers millions of dollars. We are "zero contingency", which means if we don't find you savings, there is no fee.

Stellrr Insulation & Spray Foam creates comfortable, healthy and energy efficient environments by installing spray foam, blown-in, and batt insulation in your home's walls, attic, floor, and more!

"Stellrr is, without a doubt, one of the best contractors I have used in Austin... Our home was built in 1980, and the has all the wiring and rewiring that can be expected in 30+ years... Last year, we decided to remove the old insulation from the attic as a way to get a handle on a pest issue that we had... but because the attic is so old, and so much 'stuff' is laying around, we didn't want to use the more common blown insulation as replacement; after some research, we came across Stellrr, and the abundance of information they provided enabled us to make a more educated decision that we would otherwise have made... Wayne Mansur was willing to spend a long time over the phone answering all of my questions, and when he came to our home, he was very meticulous in taking all relevant measures... The actual job took a little over two days to complete, and once it was finished, we were able to feel the effects of superior insulation from day one! I should say here that, and because we had removed the old insulation in the Fall of last year, the early days of Summer, when he had no insulation at all, were pretty toasty inside the house - the AC unit would not stop working between morning and evening, and could not catch up with the modest setting we had - 79F... Our new insulation from Stellrr has made the house much, much more comfortable, and the difference in the electric bill was evident from day one (my recollection was a drop on the electric bill of ~$70.00 compared to the previous month)... I have also been in the attic on Summer days, and when I would have previously been roasted, I was able to do maintenance work without issue, and with comfort... Without hesitation, I would recommend Stellrr to any one considering an insulation job..."

Energy Efficiency Auditing questions, answered by experts

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
