Tips to fix it at home
Here are some tips for you that might help you fix the problem yourself!
Check and change your air filter
Air filters need to be checked every 30 days and replaced every 2 months, but this depends on quality and on the unit.
Check the breaker
If the unit won't come on at all, the breaker could have been tripped.
Check your thermostat
Your thermostat may not be on the right setting or it may be out of batteries.
Give it a good cleaning
Often the system may just be dirty. Instead of an actual air conditioner repair, the unit may just need to be cleaned.
