"To hid the heat pump condenser we had the unit mounted on our house. It makes a vibrating sound in the house. But in defense of Geofurance we haven't given them a chance to resolve the problem. I would also like to say the heat pump has saved us a lot of money as far as propane cost. It also replaced a resistance heating system in our loft. It now allows us the ability to use the loft in the winter."

Energy Efficiency Auditing questions, answered by experts

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. 

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.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.
