Backup Electricity Generators: What You Need to Know
Most of us have never lived in a home without electricity. We take it as a natural right that we can stride into a room, flip a switch and be blessed with artificial illumination. We get ice from the freezer, turn on the TV, and microwave some popcorn without a thought – until that day comes when the lights don’t come on and we feel surprised and a bit betrayed. Getting your own generator installed can be done in a couple days, and can be surprisingly affordable. For more information about installing a generator for your home, please contact our technicians at Air-Tro, Inc. We serve Monrovia, Pasadena and the Greater Los Angeles area.

Four Reasons why cleaning both your evaporator coil & condenser coil is a MUST!

However, if your coils are in poor condition and are dirty, they can and will cause many problems. Call Air-Tro to schedule your coil cleaning today at (626) 357-3535.
