[unable to retrieve full-text content]Hiring a professional for AC repair service can be expensive but if you do general maintenance on your AC unit, you can reduce the AC repair service calls. One of the most effective and simplest ways to keep your AC running efficiently is to change the filter at least once a month. When a filter is clogged or dirty it will make your air conditioner work much harder. Buying new filters are easy on your budget, will help to extend the life of your air conditioner, and help to lower your utility bill. You should also make sure that the fins and AC coils on the outside of the unit are clear of obstruction and clean.
