"Fantastic experience with Paul, Mindy and their team when they helped us insulate the attic spaces surrounding and above our 1.5 story house. We have immediately seen the benefit from the insulation through our energy consumption, reducing the run-time of our unit by ~4 hours a day on like-weather days. This team will take care of your exact needs by tailoring their solutions to your specific situation and they don't cut any corners in ensuring your getting the value deserved!"

We quoted three companies to replace our old HVAC system. I asked two companies that I knew, or got referrals on, and I needed a third to round out my quoting process. I called Vitt based on the good Angie's List reviews I read, not knowing anything about them other than they looked good on Angie's List. Jeff Vitt came out and we talked about what I wanted and needed to improve our A/C needs and also reduce our energy bills . He recommended a system that was more efficient than the other companies suggested systems, and the equipment he suggested was rated higher in consumer reports than the other company's suggested equipment as well. PLUS, his pricing was better which made the choice a no-brainer for me. The installation was performed on time and done better than I hoped. For this large purchase on which I did a lot of homework, Vitt was excellent. I was a little nervous never having used them before, but I am very pleased with the service, knowledge, performance and overall value I received from them. Don't be swayed by the big name companies in town.  These guys know their stuff and do a great job at a great price. I highly recommend them for any HVAC needs.

"It went great. 
They did a great job with the energy audit.  After that, they gave a very competitive bid for a lot of work we needed on the upstairs, as the prior owner did a horrible job.  
They were fast, efficient and very flexible on our schedule.  Within a day, we noticed a major difference in the temperature situation in the upstairs - it was a major improvement.  I highly recommend!

"With the unusually wet spring this year, our hearts sank when we heard the dripping of water in our bedroom, kitchen, and living room. We called our roofing company, but they explained the problem was not the roof, but the solar assist panels. So, we checked the phone books for a company to repair them. Imagine our surprise when we discovered in this day of alternative energy we could not find a company willing to come look at the panels, much less discuss our problem. Finally, we called a solarium company, and he said, "We don't do that, but I know a handyman and if he can't fix it, no one can." We put in a call to Al Vitale and he was reluctant at first, but finally after some begging on our part, agreed to look at it in 2 days. Two days later Mr. Vitale and his assistant were there on our roof. Then he came in and asked, Has anyone looked in the attic for where the water is coming in? We felt like 2 pennies waiting for change. No, no one had ever checked the roof. Mr. Vitale climbed up in a wink, did his survey, came down, placed a call to a glass company to order the Plexiglas and gave us the quote. A couple of days later there they were again, handling every detail of the repairs. He called us 2 days ago and said he'd been very busy fixing homes for the summer selling season, but would return to repair the ceilings and repaint them in 2 1/2 weeks. We wish all tradesmen acted so professionally. I almost hate giving his name to this list, but feel everyone should find out why we recommend him without hesitation. Oh, our insurance claim representative was very impressed with the work and also with the reasonable price, so that's not just our opinion. The claim representative took Mr. Vitale's name and number and said he could keep him busy. I hope we'll still be able to call him when we need help again. Oh, no more rain coming in since he fixed it, and we've had lots of rain and hail since."

Energy Efficiency Auditing FAQs, answered by experts

Installing weather stripping or upgrading to insulated panels can improve efficiency.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.

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.
