"We bought a house in January. The house has a finished basement and looked like it only needed repainting. After a considerable amount of drywall repair, we painted. After 4 days, the paint did not dry and we could wipe it off the walls with our fingers. My wife used a digital thermometer to get readings of 37 degrees at the wall and 35 at the floor. We called Assured Energy Solutions and within a couple of days we discovered there was little to no insulation in most areas of the house. The thermal imaging and vacuum test indicated our nearly 6,000 sq. ft. house was practically an open door. Cal and Tony explained what was wrong and how they would make it right. From day one the guys showed up on time and worked feverishly to complete the day's tasks. Through every step of the way, the progress was explained. If we had questions, the workers would stop immediately and with a smile, explain what was wrong and show us the corrective action that was being taken. Sometimes the workers would call to us to show us what they had done. At the end of each day, we got a tour and a thorough explanation of the work completed and what would be next. Each day the furnace ran less and less. We also noticed the house is much quieter and feels warm and cozy. The work was completed on time. We thought the price was very reasonable. The workers were all very friendly, courteous and respectful. We are very happy customers and highly recommend this company."

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.
