"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

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.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Typically, triple-pane windows made with krypton gas filling are the most energy efficient. A window’s frame, glass, design, and installation all affect its energy efficiency. These windows, in particular, are designed highly effectively in terms of their ability to insulate.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.
