"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

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 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

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
