"Bartholomew did very poor work and greatly overcharged for installing a pellet stove, a very simple job. We waited a long time for them to come and do it, although the actual work took a very short time. They did not even plug in the stove or run it to see if it worked properly, and did not complete the required certificate as certified installer to prove the stove was installed to code and operating properly. We just failed the first inspection attempt, as inspector said that information was required to be onsite at time of inspection and Bartholomew knew (or should know) that. Reinspection fee now required, and another long delay to get completion. Bartholomew was very slapdash and unprofessional. I do not recommend them."

Energy Efficiency Auditing questions, answered by experts

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.

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

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.

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.

Depending on property size and audit scope, costs range from $200 to $600.
