Beware These Common End-Of-Season AC Repair Needs


It’s officially Fall, and while we can still likely expect some heatwaves throughout the rest of the year–after all, it is California–it’s just about time to turn our attention to our heating systems. In fact, it’s never too early to schedule heating system maintenance, if you haven’t done so already!

That said, it’s likely you have been using your AC system pretty consistently over the last few months. The absolute last thing you need now is an unexpected breakdown or huge repair issue when you still need your system.

We have some good news, fortunately! Most AC repair needs show very clear symptoms well before these issues cause your air conditioner to break down. So if you notice any of these symptoms, you can give us a call right away. Once repaired, you can rely on your air conditioner not only for the rest of our warm weather. but when you need it as temperatures warm up again next spring.

Remember, you shouldn’t ever try to formally diagnose or repair a faulty air conditioner on your own. There are potentially harmful components involved, such as the chemical refrigerant. But you can be diligent and give us a call if you notice any of these troubling AC repair signs:

Reduced Airflow

Have you noticed that the cooled air you’re used to isn’t moving through your vents and into your living space with the speed or power you are used to? This certainly indicates an issue! It usually means that air is trapped somewhere within the system, which can cause your coils to freeze over–which is a problem all on its own.

Another possibility is that your air ducts are damaged, and conditioned air is escaping into unoccupied spaces such as your attic, crawlspace, or wherever you have your ductwork installed.

Low Cooling Power

Maybe the airflow seems strong enough, but your air seems lukewarm? Factors such as refrigerant leaks, overheating components, or again–damaged air ducts–could all contribute to a decreased ability to cool down your living space.

Reduced cooling is both the symptom of a problem and a problem within itself. This is because it will ultimately cause your air conditioner to run longer to try to reach the desired temperature on your thermostat. This is inefficient and can exacerbate wear and tear on the unit.


When an air conditioner, or forced-air heating system, turns on and off rapidly, this is called short-cycling. Your cooling system uses more energy turning on than it does simply drumming, so you need yours to run for at least 15 minutes at a time. Otherwise, it’s a sign that something is amiss within your air conditioner.

“What if my air conditioner has always short-cycled?”

If this is the case, then it probably means that your air conditioner was not properly sized to begin with. To minimize this risk, you always want to work with a trained and highly experienced HVAC contractor for your air conditioner installation and services.
