"Ryan was patient and allowed me to ask questions and did not pressure me. If I get approval, from HOA, will hire Ryan to do my solar on the condominium. If approval is not met with the HOA, I will be referring him out and using Sunpower on my next single-family home purchase."

Energy Efficiency Auditing FAQs, answered by experts

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.
