"I had a deeply disappointing experience with Jerry and the new leadership at Assured Comfort. They claim to be veteran-friendly, but as a disabled veteran, I found their integrity severely lacking. They don’t stand behind their work, which was substandard from the start. During the initial job, they failed to follow building codes and took shortcuts that resulted in damage to my home. To make matters worse, when a technician was sent to fix the original sloppy work, he stepped through our coffered ceiling, causing even more destruction. The company refused to take responsibility or cover the costs for their poor craftsmanship and the resulting damage. I strongly recommend avoiding this dishonest company—do yourself a favor and look elsewhere."

Outside The Box Construction is an environmentally-aware general contractor that can accomplish all of your building needs while integrating sustainability and energy efficiency.

"Outside The Box Construction (OTBC) was hired to remodel my upstairs neighbor's bathroom due to the tile in the bathroom shower leaking water and staining my bathroom ceiling below. The first thing I noticed about OTBC during the upstairs remodel is how they cleaned up the stairwell connecting our units every day and were very polite and courteous as they were coming and going. I monitored their work upstairs as the project progressed and was so pleased with the results, that I asked them to give me a quote for a full bathroom remodel. The scope of work included: demoing the entire bathroom and replacing support beams under the floor that were rotted due to water damage which caused the floor to sag several inches, remove all debris from the site, install sheetrock and insulation, build a walk-in shower to replace my tub, tile the shower and bathroom floor with new tile, paint walls, install a new exhaust fan, install a new vanity and toilet and install all of the new bathroom hardware/accessories I purchased. In other words, do EVERYTHING! Also, the price was very reasonable, especially considering all of the different things they were required to do. Kris Walker was my main contact during the project and was very helpful and always available to answer any questions I had. He was able to help guide me through the process from beginning to end. From purchasing the tile and hardware, all the way through to the construction/installation process. OTBC stuck to schedule they gave me for the project to be complete. This was very important since I could not live there until the work was completed because I only have one bathroom in my unit. Most importantly, my bathroom looks BEAUTIFUL! All of the workmanship is top notch and the tile looks amazing! The walk-in shower makes the whole bathroom look so much larger than it used to. I LOVE IT! I will definitely will use them for my kitchen remodel!"

Energy Efficiency Auditing questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Insulation is measured by R-value, which is the measure of a material's ability to resist heat transfer. The higher the number, the better the insulation. When installing insulation yourself, you need to determine the optimal R-value you need to keep your home warm in the wintertime, cool in the heat of summer, and energy-efficient all year long. Each inch of insulation provides between a 3 and an 8 R-value. The climate where you live plays a major role in what R-value you need and the price tag you might see in your insulation installation.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
