"He's a really friendly guy, very responsive to my calls, schedules me in partly because we've had a working relationship for like six years. He's done work at the house that I live in. He replaced a furnace there and the air conditioner. The day before the warranty of the air conditioner that he had installed ran out, he installed a new one and it didn't work either. He went to the local manufacturer's distribution and got a third one and it didn't work either so he went and got me a brand new upgraded unit and a discount for all the inconvenience. He's a good guy and I have no complaints whatsoever. Sometimes, some of the worker bees that he sends when he is on a job and somebody has to come and check something, they come right away but they are not necessarily as diligent as he is."

"Kyle, Nick and the team have done a great job adding insulation to our attic (and even removing some bad stuff). Good communications, (Josie provided e-mails) discounts, attention to detail, promptness, neatness by covering floors with plastic and vacuuming when finished. The pictures were a great help as well. The invoice was "as bid" with no surprises and provided various payment options. We did not mind these guys being in our home! This company understands how to do business responsibly."

"I had 2 pieces of fascia blown off in a wind storm.  I called several companies to get estimates, but every company I called either told me they were too busy, the job was too small or they just did not call me back.  I called Morning Star on Wednesday afternoon and received a call back within the hour.  I explained what I needed (I originally thought it was siding) and Melissa asked if I could send her a picture.  I sent a picture and within 5 minutes she called me back, told me exactly what it was, and told me how many feet I would need.  She also explained that they guys were very busy, but she thought they could fit me in sometime in the next week as the crew would be in the area.  Friday she came by my house to do a color match and the guys showed up on Saturday to replace the pieces (after she texted me and asked if that was OK).  They did an excellent job and were done in about an hour and a half, including clean up.  It looks fabulous and the color matches perfectly.  I can't say enough good things about her and this company.  She was very responsive and even game me pointers about caulking some pieces in the siding where there were gaps.  I will definitely use them in the future as we have some doors that need to be replaced.

 Mr. Donohue seems to be very  knowledgeable in this field. They come out to give your a free estimate. He explains the process before he starts. Once on the job his team worked  tirelessly until the job was complete.

Energy Efficiency Auditing FAQs, answered by experts

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

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.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
