There’s a warning from Espanola Police about a firm claiming it can improve the efficiency of your home’s heating and cooling system.

Police say some area residents let the firm install the equipment and then had large amounts of money withdrawn from their bank accounts.

The company is known as Mohan Home Services.

Police are asking homeowners not to let the representatives inside.

Espanola police say if they come to your door, call the police.

The reps say their equipment improves the efficiency of your furnace, air conditioner, air filtration and electricity monitors.
