"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"They did a very good job. I've used them twice I believe. I have a scheduled service call. I like the service. The gentleman, or technician, does explain everything and he point out a few things that I might want to look into. Only issue I had was on two occasions, they came late. Not much late, but there's room for improvement there. In their listing, they list out the things they are going to do. I didn't stand over them to make sure it was done but I haven't had any problems. They are supposed to clean the unit and do the tune-up. I'm not sure what that entails. My energy bills are still fairly low. I'm assuming that has something to do with the 6 month service calls they tell you to do as a homeowner maintaining the system. The last time they came, he did bring me a filter. I did have a filter but he switched it out for another filter. No extra charge for that. Just a courtesy from the business. I can't speak negatively other than the late arrival. The price is good. I'm getting a good deal."

Energy Efficiency Auditing questions, answered by experts

Yes, with features like LED lighting and variable speed controls for efficiency.

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.
