"My loft above my garage was humid and a bit uncomfortable from what I was expecting. I’ve watched enough home repair shows and understand air flow enough to know it would never be perfect, but something was off because of the humidity issues. Mike came in and did an inspection, confirming that there was a lot of room for improvement in the garage ceiling. The heat camera was showing that there was a lot of heat transfer happening in the loft, foot prints (from boots) leaving heat transfer marks which is unusual and recommended dense insulation pack to fill the void. I sat on it for a few weeks, called and scheduled for the 17th, but got in early due to an opening. It took several hours to complete the work, and the folks said it had 5” bat insulation but a 17” void, which confirmed Mike’s original thought that there was a gap between the insulation and the loft floor which was carrying the heat from the outside into the floor."

Energy Efficiency Auditing questions, answered by experts

A good SEER rating is between 15 and 20. However, if you want the best possible efficiency, look for HVAC units with a SEER rating higher than 21. Keep in mind that the SEER rating doesn’t mean that the unit will reach that efficiency all the time, but it does have the capacity to operate at that high of an efficiency level.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.
