NORWALK - With temperatures in the 90s today, Eversource Energy says it's expecting a big spike in demand as people turn on their air conditioners.

The utility company is reminding customers that their units will work better and more efficiently if the filters and coils are cleaned on a regular basis.

They also suggest making sure the vents are not blocked.

Eversource says you should also seal up any cracks or gaps in windows and door frames to help keep the cool air in.
