"Failed to show up on agreed upon work date due to overbooking. Bid vinyl for an aluminum replacement, then was unresponsive about bidding aluminum. When we decided to go elsewhere, six months later they sent us an invoice for an additional, arbitrary $3k for work not performed. We disputed the invoice and never heard back until we got another invoice another seven months later seeking double the original amount including monthly interest and an ‘overhead & profit’ fee."

Energy Efficiency Auditing questions, answered by experts

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Depending on property size and audit scope, costs range from $200 to $600.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.
