Making simple repairs or improvements and changing wasteful habits will yield enormous energy savings for most families.

Most of us want to reduce our energy usage, regardless of upfront costs, but limited budgets prevent many homeowners from paying for expensive improvements. Here are affordable-to-most projects that will, in relatively short periods of time, pay for themselves via lower utility bills.

Some purchases and improvements move you toward minimizing or even completely eliminating your home’s net energy consumption. Unfortunately, most families can’t afford them.

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.

Although the cost of equipment has come way down, for most homeowners the biggest obstacle to going solar remains price: For a typical house in this area, you’ll have to plunk down $18,000 or more. You’ll eventually get your money’s worth, but it will take time.

Roofing work is expensive, and, if you hire the wrong contractor, you can spend thousands of dollars too much and still get terrible work. Our ratings of area roofers will help you nail down the best roofers for your job.
