San Antonio’s legendary heat waves are no joke. When summer temperatures soar past 100°F, your air conditioner isn’t just a luxury-it’s a necessity. But what happens when your trusty AC starts acting up? Many homeowners ignore early warning signs, only to be left sweating when the system finally breaks down. Don’t let a small problem turn into a costly emergency! In this guide, Kidd Mechanical shares the most common signs your AC needs repair and what you should do about them.
Before we dive into the warning signs, let’s talk about why it’s so important to catch AC problems early, especially in San Antonio:
Prevent Costly Breakdowns: Small issues can escalate quickly, leading to expensive repairs or even complete system replacement.
Stay Comfortable: Even minor AC problems can make your home uncomfortably warm, especially during peak summer.
Save Money: A struggling AC works harder, using more energy and driving up your utility bills.
Protect Your Health: Poor cooling can lead to high humidity and poor air quality, increasing the risk of mold and allergens.
Now, let’s look at the top signs your AC needs professional attention.
One of the first things you might notice is that your AC isn’t blowing cold air like it used to. Maybe the airflow from your vents is weak, or the air feels lukewarm even when the thermostat is set to “cool.”
Possible causes:
Clogged air filters
Ductwork leaks or blockages
Failing compressor
Low refrigerant
What to do:
First, check and replace your air filter. If the problem persists, it’s time to call a professional. Ignoring weak airflow can strain your system and lead to bigger breakdowns.
Your AC should run quietly, with nothing more than a gentle hum. If you hear rattling, banging, screeching, or grinding noises, something’s wrong.
Common noises and what they mean:
Rattling: Loose parts or debris in the system
Screeching: Worn-out fan belt or motor bearings
Banging/Clanking: Broken or disconnected components
Buzzing: Electrical issues or failing compressor
What to do:
Turn off your AC and call a technician. Continuing to run a noisy system can cause further damage and increase repair costs.
If you notice musty, burning, or foul smells coming from your vents, don’t ignore them.
Common causes:
Musty odor: Mold or mildew in the ducts or evaporator coils
Burning smell: Electrical issues or overheating components
Rotten egg smell: Dead animal or pest issue in the ductwork
What to do:
Musty smells can affect your indoor air quality and health. Burning smells may indicate a fire hazard. Turn off your system and schedule an inspection immediately.
Does your AC turn on and off more often than usual? Or does it seem to run non-stop without cooling your home?
Possible causes:
Thermostat problems
Dirty condenser or evaporator coils
Refrigerant leaks
Oversized or undersized AC unit
What to do:
Frequent cycling wastes energy and wears out your system. Have a professional diagnose the issue to restore efficient operation.
San Antonio summers are humid, but your AC should help keep indoor humidity in check. If your home feels sticky or you notice condensation on windows, your AC may not be dehumidifying properly.
Possible causes:
Incorrect AC size
Malfunctioning components
Dirty coils
What to do:
High humidity can lead to mold growth and discomfort. A technician can recalibrate your system or recommend a dehumidifier.
Puddles of water around your indoor unit or ice on the evaporator coils are signs of trouble.
Possible causes:
Clogged condensate drain
Low refrigerant
Dirty air filter
Faulty blower fan
What to do:
Water leaks can damage your home, and ice buildup can ruin your AC. Turn off the unit and call for repairs.
If your energy bills are climbing but your usage hasn’t changed, your AC could be to blame.
Possible causes:
Aging or inefficient system
Leaky ducts
Dirty filters or coils
Low refrigerant
What to do:
A tune-up or repair can restore efficiency and save you money. Regular maintenance is key to keeping costs down.
Sometimes, the problem isn’t with your AC unit but with the thermostat. If your system won’t turn on, doesn’t respond to settings, or displays incorrect temperatures, your thermostat may need repair or replacement.
What to do:
Try replacing the batteries and checking the settings. If issues persist, a professional can diagnose wiring or sensor problems.
Most AC units last 10-15 years with proper maintenance. If your system is approaching or past this age and experiencing frequent issues, it may be time for a replacement rather than another repair.
