How Often Should I Service My Air Conditioner?

How often should you have your AC tuned up? You may not know the answer to that one, so here is an easy one: how often should you have the oil changed in your car? The answer, it turns out, is different depending on whom you ask, what kind of car you have, what kind of environment it is used, and the type of oil put in. Some cars with certain oils (some jaguars) can go 15,000 miles or more on one oil change while others (like race cars) get the oil replaced after every use. So, how often should you have routine maintenance performed on your air conditioning system? Turns out, most manufacturers recommend once annually (in some cases require once annually for warranty compliance). Here in Florida most people would say air conditioning is essential to living comfortably, so it is important to have it “tuned-up” on time to avoid unnecessary breakdowns.

AC Maintenance Frequency in Florida

In most parts of the U.S. homes are cooled with air conditioners. How they are heated changes by region. The majority of the country uses combustion of some sort (gas, oil, kerosene, wood, pellets, etc.) for heat. In central and south Florida, most homes are heated with heat pump systems or simple electric heat. In much of the rest of the country, the cooling season may only be 3-4 months using one machine and the heating season may also be 3-4 months using a different machine. It is usually advisable to have each unit (air conditioner and furnace) serviced or “tuned-up” before each respective season, so twice a year would be the answer. In central Florida, where the AC is run the better part of 10 months and a little of all 12 months and the heat only a little bit each year, once a year will normally suffice for normal residential applications.

Signs Your AC Unit Needs a Tune-Up

There are some other things besides the calendar that can let you know you need a tune-up. Here are a few signs to look for which indicate that the AC unit is ready for some professional TLC or worse, ready to fail:

  • Unusual Noises. The most common sign that an AC unit needs a tune-up is noise. The machine screeches loudly as the mechanisms work harder to cool down the home. If the unit were functioning normally, the noise would be at a minimum; it would not be working hard enough to produce angry or wounded animal sounds. The annoying clatter usually happens because the machine is not performing properly, so it has to work harder to make up for the performance deficit.
  • Poor Performance. The home can take a long time, to cool down, or never reach the desired temperature. Although AC units usually take a little longer to maintain optimum temperatures in bigger homes or at the hottest times of the year, if the difference in cooling time is drastic enough for the homeowner to notice, the AC unit is probably in need of a tune-up.
  • High Energy Bills. When performance goes down, costs go up. High utility bills are usually a sign that an air conditioning unit is struggling. This is because the unit must use more power to compensate for the issue causing it to malfunction. It takes longer to cool down the house, which means it is running at the same or higher power output for an extended period of time. That’s not good for you, but great for the electric company. If the utility costs are higher than usual, it is likely that the air conditioning unit is working harder, which means it probably needs a tune-up.

Although there are other signs of declining AC performance, the most noticeable indicators are loud noise, longer duration of operation, and increased utility bills.
