DIY Air-Conditioning Repair (and When To Throw In The Towel)

DIY Air-Conditioning Repair
Summer is here –yay! But with the summer comes the heat. This is why you need to start checking out your air conditioning unit now. As you already know, these are the days when your AC is going to be running nearly 24 hours a day.

This is when you need your AC to be in top shape. This is why you need to start carrying out routine preventive maintenance and learn some do-it-yourself repairs. The latter is particularly important in the summer.

Having some basic knowledge of how to fix a few things will ensure that in the event that your AC quits on you or develops an issue in the middle of a really hot summer afternoon –why do they always do that? ha!- you’ll be able to at least keep it running until your HVAC repairman gets there.

Routine Preventive Maintenance

Filters – Get the new high efficiency filters with electrostatic charge and replace it every three months at the latest. These are extremely effective at catching even the tiniest particles. But, make sure to have a look at the filter every month. If you have pets, you should change them every month as animal hair and dander can help clog the filter fast.

Debris – Clear out the area surrounding your AC unit to within 2ft and get rid of all debris, leaves, plants, twigs and rubbish there. This way, there’s less chances of having any of those particles clogging your AC and filters getting clogged quickly.

Insulation – Check the insulation around the refrigerant frequently and replace it if there’s none or it has some damage.

Carbon Monoxide Detector – Make sure to check your carbon monoxide detector every six months to see if it’s functioning well. This may or may not be a part of your AC unit, but in either case, it does the job of alerting you when the carbon monoxide levels are high in the house, thus saving the lives of everyone in the home.

DIY Troubleshooting

Be Safe! Before embarking on any do-it-yourself repairs, shut off the AC and disconnect the socket from the mains. Then wait for at least half an hour to be sure that all residual electricity is fully discharged.

If your AC isn’t blowing cold air, check your thermostat and see if the temperature is already lowered. If yes, check the registers in the home to be sure that they are all open. Then, check the filters to see if they are clogged. If they are clogged, you will need to replace them. Also, check the condenser coils and have them cleaned.

After changing the filters and opening the registers, the AC should start cooling. If it isn’t, check the evaporator coil or A-coil and see if it’s iced. If it is, you will have to de-ice it.

Finally, turn off the thermostat, turn on the fans and allow the air flow through the registers. Wait until you have good airflow, then turn the fans back to “auto” and the thermostat to “cooling” again.

That’s all the preventive maintenance and do-it-yourself tips we would generally recommend that you take care of yourself. If your air conditioner is still not blowing cold air after these steps, it’s time to call a local HVAC repair service like Bob Heinmiller in Orlando so they can find what’s wrong and fix it.
