Air Conditioning Repair For St Charles Mo
The air conditioning system is a bit more tricky than the furnace.
- Shut the power off
You need to power down the entire system. Go to the plugin closest to the system and pull the plug. You will want to make sure the system is actually off.
- Contactor check
With the system verified that its off, check your connections. a contactor is on the list of common repairs. Check the wires and make sure they still have good connections. IF it is loose, undo the wire and replace it back in the spot with a better connection and screw it down.
- Motor Fan
If you notice the fan is having troubles you can replace that as well. Losen the setscrew then pull it off the shaft. Replace with new motor. Secure wires off the old conduit
you want to check for any amount of current. Alot of people turn volt meters way down to the lowest. Place black and red on opposite sides of the fuse. A numbered reading will indicate a good fuse.
- Capacitor Replacement.
Capacitors do not last for ever. Ordering a new one isn’t the worst idea. before you remove the old one make sure you get a drawing of how it looks. You want to make sure it is installed the correct way.
Sometime you can change the filter, this filter can cause problems when it is dirty. The system will overload on power and turn its self off. Check to see if ice formed on the coils.
- You should check the thermostat to make sure it is set to heat.
Looking at the thermostat it should be set to on. Also you need to make sure that it is set to heat. If you think its hot you may need to adjust the temp on the thermostat to kick the system on.
- Checking the filter.
I have to say this is the most common cause of furnace problems. The filter gets dirty. So imagine breathing through a straw, it requires you to breathe a lot harder and you start panicking because you are not getting enough breath. Well the furnace will work the same way. You should change the filter monthly. Do not cheat your self by using cheap filters. If you spend a little more on the filter it will help in the long run.
You will want to check your circit breaker. Sometimes they get tripped. if the system had a influx of air, it could cause it to kick off. Also check the on and off switch on the system its self. This is an important step, if you have kids you should do this first. Kids are adventurous and they like to touch stuff.
- Repeat the step before and listen for the sound of a spark, next clean your furnace flame sensor.
Listening for the spark will let you know if you are onto something. Clean your furnace flame sensor, they get dirty fast.
- Loose wires.
Loose wires are an easy fix. If you see a loose wire grab a screwdriver and make sure you tighten it down. If a wire is frayed or burnt you need to figure out why that is.
- Dust and Dirt.
Take the front plate off. Sometimes it will require a screwdriver to take it off. Once you get the face plate off you can get to cleaning. Just like every other part of your home, it will accumulate dirt and dust. using a flash light will help you see spots that really need to be cleaned.
- Flush drain lines.
You would be surprised at the amount of water a high efficiency furnace can drain. Check for and restrictions in the lines. you will look for dirty particles along the line. you can use bleach and water to flush the lines.
- Blocked or leaky ducts
One room is hot, the other is cold. Check your registers to make sure they are open. Looking along the duct work is hard in newer homes. You can start at the furnace, follow the duct work from beginning to as far as you can. Use a flash light. if you see a spot that is questionable. Use some soap water to see if it has a hole. You can also use your hands to feel air.
Make sure you have the right tools for the job.
