The warm weather is just around the corner for Battle Creek homeowners. Thinking about your air conditioner becomes more important. What condition was it at the end of last season and over the winter.
When your air conditioner won't come on, it can be very frustrating; you just sit there and sweat! No Fun!
Air Conditioners are designed for reliability (assuming they've been maintained) over a long period and are one of the most expensive and most needed appliances in almost every home.
Reasons for the air conditioner not working can be complex or very simple. While you are probably better off leaving the difficult problems of thermocouples, wiring and motors to a qualified professional, there are a good number of things you can check before you phone a qualified HVAC contractor for service.
Here are some initial things to check if you decide to do your own troubleshooting:
Check the settings on your thermostat. Make sure the temperature control selector is set below the current room temperature, and the system switch is on the COOL or AUTO position. The fan switch should be set to ON for continuous airflow or AUTO if you want the blower to operate only while the air conditioner is operating.
Try to get the air conditioner to turn on by lowering the thermostat to its lowest temperature setting.
If the air flow out of your registers seems low, check the air filter. An extremely dirty air filter can block air flow.
Make sure all registers are open and not obstructed.
Check the power disconnect switch by each unit (outdoor and indoor).
Check the fuse/breaker at the electrical panel for both the outdoor and indoor unit.
If the problem persists, please call us.

Try 'Troubleshooting' The Problem:
- The first place to look is the thermostat. It may sound simple, but check to see that it is turned on. All modern thermostats have an on off switch, but they are not clearly labeled with an “on” position. The “on” position is labeled “heat” or “cool.” Obviously you want to make sure the switch is in the “cool” position. If you have a programmable thermostat be sure you bypass the program by adjusting the temperature number and pressing the “hold” button. If the A/C still does not come on you’ll want to check to see if your thermostat has a replaceable battery and check it.
- If your A/C system still does not come on, look for an on/off switch at the furnace itself. It looks just like a light switch and is often attached to the unit itself, or very nearby. Make sure the switch is on. If you have central air-conditioning as part of your system and it worked properly over the summer, then more than likely your switch is already on.
- Is the furnace/air handler fan running? If it is not, then, check to see if the fan on the outside unit is running. If the fan on the outside unit is not running either, check to make sure that the breakers in your electric panel for the furnace/air handler and the air conditioner are on. The breaker could have tripped and the solution to the problem could be as easy as flipping the switch.
- If all switches are on, the problem could be with the cover on the front of the furnace. The cover often has a trip switch which shuts off the system when it is opened. If the cover is not properly closed, the switch can prevent the blower in your furnace from running.
- If the blower(in your furnace) is running but the fan on the outside unit is not, then continue your air conditioner troubleshooting at the outside unit. If the blower on the furnace is running, check to see if you see any frost or ice around the units. You might also notice water around the furnace. Is there ice on the copper lines going outside? If yes, then shut the outside unit off for a couple of hours but let the blower on the furnace run. This will allow the ice to melt.(also a good time to have it serviced)
