Whether or not you’re ready to switch to solar, take the following steps to help you learn about your options on what to buy, whom to buy it from, and how to calculate potential benefits.

Whether you decide to buy or lease a system, there are many decisions to make, the most important of which is choice of company.

If you live in the District or Maryland and want to go solar but don’t want to pay $20,000 or more up front for it, then leasing a solar energy system may be a better option for you than a purchase.

To make sure your heating and air-conditioning systems work when needed, they must be properly installed and maintained. We’ve rated area heating and air-conditioning services for quality and price.

Before considering insulation improvements, first find and plug air leaks—holes, cracks, and gaps that let cold air in and warm air out in the winter—and do the reverse in the summer.

We receive a disturbing number of complaints from consumers regarding window installation work, often about companies that advertise heavily. Many complaints are about sloppy work.
