It's Hot in El Cajon - Why Won't My AC Turn On?

Signs of a Broken AC Unit

Isn't it frustrating when the air conditioner suddenly stops working when you need it the most? Look for popular signs that your air conditioner needs a tune-up or repair to ensure you never break a sweat in the El Cajon sun.

  • AC not producing any cold air
  • AC won’t turn on
  • AC keeps short cycling
  • Strang sounds are coming from the AC
  • AC produces foul odors
  • Water is leaking from the AC

Common reasons AC won’t turn on include

  • Tripped Circuit Breaker: The circuit breaker protects your home from electrical overload. If you use too much electricity all at once, it can trip the circuit breaker, causing your AC to stop working. Check your circuit breaker to make sure that isn't the culprit!
  • Broken Thermostat: The thermostat's job is to read the temperature and tell the AC unit when to turn on and off. If it can’t accurately gage the temperature, it won’t be able to turn your air conditioner on.

Call Blue Diamond if you need helping diagnosing your air conditioning system. We can accurately diagnose the problem and provide reliable El Cajon AC repair to keep you cool all year long.

Sounds You May Hear Coming from Your Furnace

Furnaces can be very noisy at times, to the point that you might suspect a problem. Here, we'll go through some of the different noises a furnace can make and which need the attention of a furnace repair specialist in El Cajon.

  • Popping: Your ductwork is probably expanding or contracting, as its temperatures get hotter and cooler.
  • Grinding: This happens when the motor bearing has an issue. Call a professional to address this problem immediately, after shutting off the system.
  • Banging: You may have a dirty burner that is not igniting correctly. Inspecting and cleaning these is part of our maintenance program, and we can come take a look when you call us for a repair.
  • Rattling: You could have loose panels that need to be tightened or replaced. We'll take a look for you!
  • Squeals: You may need a new belt that connects he motor to the fan.

We will assist you in getting your furnace back in working order if it has stopped working or is not performing at its best.

History of El Cajon San Diego

The city's name is Spanish for "The Box" and takes its name from Rancho El Cajón, since valley that surrounds the city is a box-like shape. The name, however, is not as exciting as how many wonderful & exciting things there are to do. Here are a few of El Cajon's fine attractions:

The Magnolia is the newest entertainment destination for greater San Diego County, right in the heart of El Cajon. It opened in mid-September of 2019 and more than eight million dollars were put into the center. If you enjoy hearing to live music, going to concerts, and fun events, then check out The Magnolia!

This hotel built in 1876 is part of the El Cajon Historical Society, and is near Main Street and Magnolia Avenue at 280 N. Magnolia Avenue. It was previously a two-story, 7-room structure serving as Knox's residence and is a few blocks down from the United States Postal Service on Lexington Ave.

Gillespie Field is is located at 1960 Joe Crosson Drive and is the oldest and largest of the County’s eight airports and located in the northwest corner of El Cajon and is an flagship landmark in its community. You'll see the tower, runways, and a terminal year-round but there is a hidden gem - a yearly airshow.

St. Madeleine Sophie's Center and Garden

Here you'll see and smell a citrus orchard, breathtaking flower gardens, a greenhouse operated solely by the sun, a propagation house, trees and shrubs that accent the area, and fragrant herbs. If you're in El Cajon, it's hard not to visit this lovely landmark at 2119 East Madison Avenue in El Cajon.
