"Like some of the other people have stated.. they are pricey and they are also extremely busy. We worked with Andy as the sales rep and he was a great guy. We told him what we were willing to spend at most and he made sure we got everything we wanted for that price. I think people who are new to construction work might see these guys as a hassle but in all honesty.. the men they had working for us were some of the hardest working and fastest working men I’ve ever met. Everything was done in a week and a half.. and it is STUNNING! My only complaint is that we were supposed to get it started 8 weeks after signing and it didn’t start til about 12 weeks.. like I said though.. it’s a very busy time of the year. COVID-19 has everyone at home with their honey-do list and EVERYWHERE is booked. I would absolutely recommend Cronkhite.. always negotiate on price.. and make sure to check the work being done. Don’t watch them do something wrong and complain about it after.. If you have questions then ask them!"

Energy Efficiency Auditing questions, answered by experts

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

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.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

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.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.
