"Fantastic experience with Paul, Mindy and their team when they helped us insulate the attic spaces surrounding and above our 1.5 story house. We have immediately seen the benefit from the insulation through our energy consumption, reducing the run-time of our unit by ~4 hours a day on like-weather days. This team will take care of your exact needs by tailoring their solutions to your specific situation and they don't cut any corners in ensuring your getting the value deserved!"

Energy Efficiency Auditing FAQs, 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.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours.
