High energy costs take a huge bite out of most homeowners’ budgets. There are many things you can do to reduce your energy bills, such as purchasing energy-efficient appliances or switching to low-watt bulbs. When it comes to heating and cooling, the most effective way to cut your bills is to ensure you home has the right amount and type of insulation. This requires inspecting your home to determine how much insulation you have. Since Fresno and the surrounding area have average lows in the 30s and average highs in the 90s, your insulation should be designed for these extremes.
