You'll need to know which energy-efficient home improvements will actually save you money on your skyrocketing summer electric bill.
We asked the folks at EES Consulting; they do energy audits for businesses and homeowners.
Turns out, some of the most effective repairs are also the cheapest, like replacing weather-stripping around doors and windows.
If you have incandescent or halogen light bulbs, you could switch them out for new LED bulbs, which use up to 80% less electricity and emit almost no heat.
A test of your HVAC air ducts can detect leaks that could be draining your wallet.
But EES president Dan Parsley says, some of the most expensive fixes are also unnecessary.
"We rarely ever recommend new windows," Parsley said. "There's no payback in new windows. Today it is much more cost effective to treat existing windows with products like the Huper Optik solar film product."
Today's solar film is practically undetectable, if properly installed.
It can reduce the heat entering your window by about 70%, according to Parsley. And it will almost eliminate UV rays, which can bleach your furniture or carpeting.
