That’s exactly why we put together this ac unit troubleshooting guide — to help you identify what’s going wrong and know when it’s time to call the experts at Texas Reliable Services in Austin at (512) 609-8103.
AC Not Blowing Cold Air
Image Source: Sahil Service
Warm air blowing from your vents instead of cool air is one of the most frustrating AC problems you’ll run into — and it rarely shows up without warning. Your system usually gives you signs before things get worse.
Signs Your AC Isn’t Cooling Properly
Here’s what to watch for:
-
Warm or room-temperature air coming from vents
-
Weak airflow, even when the fan runs continuously
-
Unusual noises like buzzing, rattling, or grinding
-
Water leaks around the indoor unit
-
Frequent on-and-off cycling without reaching the set temperature
-
Rising energy bills with no change in usage
-
Erratic thermostat behavior preventing proper cooling cycles
Common Causes of Warm Air
Several things can prevent your AC from doing its job:
-
Incorrect thermostat settings: The fan set to ‘ON’ runs continuously, pushing uncooled air through your vents. Your thermostat might also be set to ‘HEAT’ or ‘OFF’ instead of ‘COOL,’ or the temperature setting is simply higher than the current room temperature.
-
Clogged air filters: Dirty filters choke off airflow, forcing your system to work harder while cooling less. Blocked filters can also cause the evaporator coil to freeze.
-
Low refrigerant levels: Refrigerant doesn’t get used up during normal operation. If levels are low, there’s a leak somewhere in the sealed system. Without enough refrigerant, your AC simply cannot absorb heat and cool your air effectively.
-
Dirty outdoor condenser coils: Dirt, leaves, grass clippings, and pollen build up on the coils over time. This traps heat inside the system, causes the compressor to work overtime, and can eventually lead to shutdown.
-
Frozen evaporator coil: Ice buildup blocks airflow and prevents proper heat absorption. Dirty filters, blocked vents, or low refrigerant are usually the culprit.
-
Electrical problems: Loose or corroded wiring, tripped circuit breakers, or failed capacitors all interfere with proper system operation.
-
Compressor failure: The compressor circulates refrigerant through the entire system. When it fails, your AC cannot cool your home at all.
How to Fix This Issue
Step 1 — Check your thermostat. Make sure it’s set to ‘COOL’ and the temperature is a few degrees below the current room temperature. Switch the fan from ‘ON’ to ‘AUTO’ so it only runs during actual cooling cycles. Fresh batteries help too!
Step 2 — Inspect your air filter. Turn off the system first, then pull out the filter and check for dirt or blockage. Most filters cost just $5 to $20 and take under five minutes to swap out. No reason to skip this one.
Step 3 — Clear debris from your outdoor unit. Remove tall grass, sticks, and leaves around the condenser. A gentle rinse with a garden hose on a low setting can knock off dirt buildup without damaging anything.
Step 4 — Check your electrical panel. Reset a tripped breaker once if needed — but if it keeps tripping, stop. Repeated tripping is a sign of a deeper electrical problem that needs a professional.
When to Call Texas Reliable Services
Some issues go beyond DIY. Refrigerant leaks require certified technicians with the right tools to locate the leak, repair it, and safely recharge the system — repairs typically run $200 to $600 depending on refrigerant type and leak severity. Frozen coils need professional cleaning or replacement, with costs ranging from $150 to $450 for cleaning and $600 to $2,000 for coil replacement. Compressor repairs fall between $400 and $1,300, while full replacement can run $1,500 to $3,000 or more.
Our certified technicians at Texas Reliable Services handle refrigerant leaks, electrical faults, and component replacements — and we respond quickly. Give us a ring at (512) 609-8103 for reliable service throughout Austin and the surrounding areas.
Frozen Evaporator Coil
Image Source: Northern One Hour
Ice on your AC unit sounds like it shouldn’t be a problem — but frozen evaporator coils are one of the most common air conditioning problems we see, and they can do serious damage to your equipment if you ignore them.
Signs of a Frozen Coil
Spotting this early is important. Catching it before compressor damage sets in can save you hundreds of dollars. Here’s what to look for:
-
Ice coating the evaporator coil itself
-
Frost on the copper refrigerant lines that run to your outdoor unit
-
Water puddles near the indoor air handler as ice melts
-
Warm air blowing from vents instead of cool air
-
Weak airflow throughout your home, indicating ice is blocking circulation
-
Excess condensation or water pooling near the indoor drain pan
What Causes Coils to Freeze
Restricted airflow is the number one culprit. When dirty air filters block warm indoor air from reaching the coil, temperatures drop below freezing. Replace filters every 30 to 90 days — more frequently if you have pets or run your system heavily. Furniture or drapes sitting over return vents create the same problem, starving your system of airflow.
Low refrigerant from leaks is another common cause. It drops system pressure and makes coil temperatures fall too low. If you notice an oily residue around indoor coils or hear hissing sounds near refrigerant lines, that’s a leak — and it needs professional attention right away. Dirty evaporator coils themselves also restrict airflow as dust builds up and acts like insulation.
Malfunctioning thermostats can contribute as well, especially with overnight freezing. Blower motor problems reduce airflow over the coil in a similar way.
Troubleshooting Steps
Here’s what you can do right now:
-
Turn your system off immediately at the thermostat to protect the compressor.
-
Switch the fan setting to ON rather than AUTO — this circulates warm air and speeds up thawing.
-
Do not switch heat pumps to defrost mode for frozen indoor coils. Defrost only works on outdoor coils during heating operation.
-
Allow two to four hours for natural thawing. Never chip ice away with tools or use a hair dryer — thermal shock can crack components and cause refrigerant leaks.
-
Replace your air filter and make sure all vents are open and unobstructed.
If the coil refreezes within 24 hours after replacing the filter, you most likely have a refrigerant leak.
Professional Repair Options
Refrigerant leaks require licensed technicians to locate, repair, and recharge the system. Repair costs range from $150 to $400, plus $50 to $100 per pound of refrigerant. Running a frozen system without addressing the root cause risks compressor damage — and that can cost $1,200 to $2,500 in parts alone.
No job too small, we do it all! Texas Reliable Services in Austin is ready to help with expert frozen coil diagnosis and repair. Our certified technicians use refrigerant gauges, pressure testing, and airflow analysis to find the root cause fast. Give us a ring at (512) 609-8103 for reliable service you can count on.
Refrigerant Leak
Image Source: Oxmaint AI
Your AC circulates refrigerant through a sealed loop — absorbing heat from inside your home and releasing it outside. That sealed system should hold the same refrigerant charge for the life of the unit. So if levels drop, that’s not normal. It always means there’s a leak somewhere.
How to Identify a Refrigerant Leak
Your system will tell you something is wrong if you know what to listen and look for. Hissing sounds near your indoor unit suggest gas escaping through holes or cracks in the coils. Larger leaks can produce bubbling or gurgling noises. Your home starts taking noticeably longer to cool down, or the system just runs and runs without ever reaching your thermostat setting. Indoor humidity climbs even with the AC going, creating that sticky, uncomfortable feeling — and conditions that invite mold growth.
Higher electric bills show up without any rate increases or changes in how you use your home, because your system is working overtime trying to compensate. Ice forms on the evaporator coils when there isn’t enough refrigerant to absorb heat properly, so condensation freezes instead. With R-22 refrigerant, you might even notice a faint, sweet odor — almost like nail polish remover. And a visual check around fittings, valves, and refrigerant lines may reveal oily residue or staining where refrigerant mixed with oil has escaped.
Why Refrigerant Leaks Happen
Formicary corrosion is one of the sneakier culprits — it creates microscopic pinholes in copper coils through chemical reactions between the metal and volatile organic compounds found in everyday household products like hairspray, cleaning supplies, and air fresheners. Constant vibrations during operation cause copper lines to rub against components, wearing them down gradually until leaks form, or joints in the coils begin to separate. Physical damage from lawn mowers, falling debris, or yard work can impact outdoor condenser units and exposed copper lines. Poor soldering during the original installation degrades over time, creating slow leaks at weak joints and connections.
The Repair Process
Licensed technicians use electronic leak detectors, UV dye, or soap bubble solutions to pinpoint exactly where the leak is. EPA Section 608 regulations require recovering the existing refrigerant with specialized equipment before any repairs can begin. From there, technicians either braze new copper sections in to replace damaged tubing, or replace entire evaporator or condenser coils when corrosion is too extensive. Dry nitrogen then pressurizes the system to verify the repairs hold under real operating pressures. Finally, the system gets recharged with the manufacturer-specified refrigerant amount — typically 2 to 4 pounds per ton of cooling capacity.
Environmental and Safety Concerns
Modern refrigerants like R-410A are non-toxic in small amounts, but high concentrations in a confined space can cause dizziness, headaches, and nausea. R-22 is no longer manufactured or imported in the U.S. as of 2020 because of its ozone-depleting properties. Refrigerants are also potent greenhouse gases — releasing them into the atmosphere is both harmful and a violation of federal regulations.
Texas Reliable Services in Austin employs EPA-certified technicians with the proper recovery equipment to handle refrigerant safely and legally. No cutting corners, no shortcuts. Call us at (512) 609-8103 and we’ll take care of it the right way!
Clogged or Dirty Air Filters
Image Source: Comfort Temp
Your air filter is the first line of defense for your HVAC system — blocking dust, pollen, pet dander, and airborne particles before they cause damage. It’s a simple component, but it’s one of the most overlooked parts of routine home maintenance. And when it gets ignored, it directly hits your cooling performance, energy costs, and indoor air quality.
Impact on AC Performance
A clogged filter restricts airflow — and that’s where the trouble starts. Your system needs 350 to 450 CFM per ton of cooling capacity to work properly. When a saturated filter blocks that airflow, your blower motor has to work harder while pushing less conditioned air into your living spaces. The result? Weak airflow from vents, uneven temperatures between rooms, and longer run times without the cooling you need.
Your energy bills feel it too. The U.S. Department of Energy estimates that swapping out a clogged filter can lower your AC’s energy consumption by 5% to 15%. For most households, that’s $7 to $20 every month in wasted costs. On top of that, the added strain wears down components like your blower motor faster, which can lead to premature failures and professional repair bills down the road.
Indoor air quality takes a hit as well. Dust, pollen, and allergens bypass the saturated filter and recirculate through your home — settling on furniture and aggravating respiratory conditions. In more severe cases, restricted airflow causes evaporator coils to freeze because not enough warm air passes over them.
How Often to Replace Filters
Filter replacement isn’t one-size-fits-all. Here’s a general schedule based on filter type and household conditions:
-
Standard 1-inch fiberglass filters — Replace monthly
-
Pleated 1-inch or 2-inch filters — Last 60 to 90 days; 4-inch models stay effective for three to six months
-
High-capacity 5-inch filters — Can go up to 12 months
Pets accelerate filter saturation, so homes with multiple pets need monthly checks and potentially more frequent changes. Smoking indoors, burning candles, frequent cooking, or living near construction zones all call for 30-day replacement cycles. Allergy sufferers benefit most from MERV 12-16 rated filters — check those monthly.
DIY Filter Replacement Guide
Good news — replacing your filter is something you can handle yourself in just a few minutes!
-
Turn off your system at the thermostat before starting
-
Locate the filter near your air handler unit or behind the return air grille
-
Remove the old filter and note the airflow arrow direction on the frame
-
Hold the filter toward a light source — if light doesn’t pass through, it’s time for a replacement
-
Insert the new filter with arrows pointing toward the blower motor, secure the cabinet, and restore power
That’s it! Most filters cost between $5 and $20, and the swap takes under five minutes. It’s one of the easiest ways to keep your system running smoothly.
Drainage and Condensate Line Problems
!Image
Image Source: San Antonio Air Conditioning Services and Repair
Most homeowners never think twice about the condensate drain line — until water starts pooling on the floor. This ¾-inch PVC pipe channels moisture away from your evaporator coil and drain pan, preventing structural damage and keeping unnecessary strain off your AC system.
Signs of Drainage Issues
Your indoor unit will tell you when something’s wrong with drainage. Here’s what to watch for:
-
Pooling water around your indoor unit — the drain line isn’t moving water the way it should
-
Water sitting in the drain pan — this signals a blockage that can overflow and flood surrounding areas
-
Rust on the drain pan — a sign of water damage from persistent clogs
-
Musty odors from vents — excess humidity creates mold growth inside the system
-
Cooling struggles or system won’t restart — drainage problems can affect how your AC operates overall
What Causes Clogs and Blockages
Several things can cause your drain line to back up:
-
Dust and dirt build up inside the line during normal operation
-
Algae thrive in moist conditions and are a leading cause of backups, especially here in Texas
-
Mold and mildew develop in standing water inside the drain pan and line
-
Improper installation without adequate slope causes stagnant water conditions
-
Insects and rodents sometimes nest inside AC drain lines
Cleaning Your Condensate Line
The good news? You can handle basic drain line cleaning yourself. Here’s how:
-
Turn off your AC system completely before starting any work
-
Locate the drain line near your outdoor condenser unit and indoor air handler
-
Remove the cap and inspect with a flashlight for debris, mold, or blockages
-
Use a wet/dry vacuum to suction out clogs from both ends
-
Pour one cup of white vinegar down the line and let it sit for 30 minutes
-
Flush thoroughly with water afterward
Preventing Water Damage
Schedule professional maintenance checks with Texas Reliable Services to catch potential issues before they turn into major problems. Replace air filters every three months to prevent dust buildup on evaporator coils. Flush your drain line every few months to stay ahead of debris.

Faulty AC Capacitor
!Image
Image Source: HomeGuide
Every AC system has a motor — and that motor cannot do its job without a capacitor. This small cylindrical device stores electrical energy and releases it in powerful bursts, giving your compressor and fan motors the jolt they need to get started. No capacitor working properly means no cooling cycle, plain and simple.
What the Capacitor Does
Think of the capacitor as a temporary battery for your AC motors. The moment your thermostat calls for cooling, the capacitor delivers a quick burst of electricity to get those stationary motors spinning. Once the system is up and running, it keeps supplying steady power throughout the entire cooling cycle to maintain stable operation. Most capacitors fall somewhere between 5 and 80 microfarads, with voltage indicating how much current flows through the device.
Signs of Capacitor Failure
Watch out for these warning signs — they tell you the capacitor is struggling:
-
Humming from the outdoor unit — the motor is trying to start but not getting adequate torque from the capacitor
-
Warm air from vents — one of the earliest indicators that something is off
-
Delayed or failed startup — your system takes several seconds to turn on, hesitates, or won’t power up at all
-
Random shutdowns mid-cycle — the capacitor can’t maintain consistent charge to keep the motors running
-
Rising energy bills — your AC works harder as the capacitor degrades, even if your usage hasn’t changed
-
Burning smell or visible smoke — shut the system down immediately and call a professional. Malfunctioning capacitors are a fire hazard
-
Visible damage on the device itself — bulging tops, fluid leaks, or burn marks are clear red flags
Replacement Cost and Timeline
AC capacitor replacement typically runs between $120 and $400, parts and labor included. The part itself costs $10 to $60 — labor makes up the bulk of the expense. With regular maintenance, capacitors can last 15 to 20 years, though heavy use and heat exposure in Texas conditions will accelerate wear.
Capacitor work involves high voltage and is not a DIY job. Texas Reliable Services in Austin handles capacitor replacements quickly and safely. Give us a ring at (512) 609-8103 for expert diagnosis and repair!
Malfunctioning Thermostat
!Image

Your thermostat is the command center of your entire AC system. It tells your system when to start cooling, how long to run, and when to shut down. When it stops working correctly, even a perfectly good AC unit cannot keep your home comfortable.
Common Thermostat Problems
Blank screens are usually the first thing homeowners notice — and they’re often caused by dead batteries, loose wiring, tripped breakers, or complete device failure. A system that won’t respond to temperature adjustments points to faulty circuitry preventing communication with your AC. Units running nonstop suggest the thermostat cannot signal shutdown commands, possibly due to bad wiring or calibration drift. Short cycling happens when incorrect temperature readings trigger premature on-off cycles. Erratic temperatures and hot or cold spots throughout your home point to failing sensors. Programmable models forgetting settings require recalibration or software updates.
Calibration and Settings Check
Here’s what you can check on your own before calling for help:
-
Verify your thermostat sits level — mercury switches in mechanical models depend on proper positioning
-
Clean interior components with compressed air or a soft brush to remove dust, cigarette smoke residue, and debris
-
Check placement away from direct sunlight, heat sources, cold drafts, and isolated rooms that don’t represent actual home temperatures
-
Place a quality digital thermometer within two inches of the thermostat for 15 minutes and compare readings — a variance exceeding 1.5°F warrants calibration
When to Upgrade Your Thermostat
Thermostats over 10 years old or reading more than 5°F off actual temperature? At that point, replacement makes more sense than repeated calibration attempts.
Smart Thermostat Benefits
ENERGY STAR certified smart thermostats save approximately 8% on heating and cooling bills, averaging $50 annually. These devices learn your schedule, adjust automatically based on occupancy and weather, and give you remote control right from your smartphone. That’s a win for your comfort and your wallet!

Compressor Issues
!Image

The compressor is the heart of your AC system. It pressurizes refrigerant and circulates it between your indoor and outdoor units, making heat transfer — and actual cooling — possible. Without it working properly, your AC simply cannot cool your home at all.
Role of the Compressor
Here’s what happens inside: the compressor takes low-pressure refrigerant gas and squeezes it into high-pressure, high-temperature gas. That process is what pulls warmth out of your home and sends it outdoors. It runs continuously during every cooling cycle, which makes it one of the hardest-working components in your entire system.
Warning Signs of Compressor Failure
Your AC will let you know when something’s wrong. Watch out for:
-
Warm air from vents — the compressor can no longer circulate refrigerant properly
-
Loud clicking, humming, banging, or rattling noises — these point to internal damage
-
Frequent circuit breaker trips — the compressor is drawing more electrical current than it should
-
Hard starting or failure to turn on — seized components or electrical problems are likely the culprit
-
Rising energy bills — reduced efficiency as the compressor struggles to keep up
Repair vs. Replacement Decision
Not sure whether to repair or replace? Here’s a straightforward way to think about it:
Repair makes more sense when:
-
Your system is under 8 years old
-
The damage is electrical rather than mechanical
-
Repair costs stay under 30-40% of what a full replacement would cost
Replacement becomes the smarter call when:
-
Your system is over 10-12 years old
-
The compressor failure is mechanical
-
Repair costs exceed 50% of replacement cost
Cost Considerations
Minor electrical repairs typically run $200 to $600. A full compressor replacement, on the other hand, can cost anywhere from $1,200 to $3,500 or more, with labor making up 40-60% of the total. It’s a significant investment — and one you want done right the first time.

Blower Motor Problems
!Image

The blower motor is what keeps conditioned air moving through your home. When it starts to struggle, your entire cooling system feels it — even if every other part is working just fine.
Symptoms of a Failing Blower Motor
Your indoor unit will tell you when something is wrong. Here’s what to watch for:
-
Grinding, squealing, or rattling sounds from your indoor unit signal worn bearings or debris caught in the assembly
-
Weak airflow from vents means the motor cannot spin at full speed, even while running
-
Uneven temperatures between rooms point to inconsistent heating or cooling caused by poor air circulation
-
Frequent on-and-off cycling suggests the motor is overheating and triggering safety shutdowns
-
A burning smell from vents means the motor is overheating — shut the system down immediately and call for help
What Causes Motor Failure
A few things wear a blower motor down over time:
-
Dirty air filters force the motor to work harder than it should, leading to overheating
-
Worn bearings create noise and will eventually cause the motor to fail
-
Electrical problems with wiring, capacitors, or relays prevent the motor from operating properly
-
Debris buildup inside the unit hinders motor performance
-
Age is a factor too — most blower motors last between 10 and 15 years
Professional Diagnosis and Repair
We aim to never miss any detail when diagnosing a blower motor problem. Our team at Texas Reliable Services in Austin tests capacitors, inspects relays, measures voltage, and checks blower wheels for balance. Replacement costs typically range from $600 to $1,200.

Electrical and Wiring Issues
!Image
Image Source: Electrexia.com
Electrical problems are among the most serious common air conditioning problems you can face at home. Residential AC systems operate on high-voltage electricity — typically 220V — and that means electrical faults aren’t something to take lightly or guess your way through.
Common Electrical Problems with Air Conditioners
Faulty wiring sits at the root of most electrical failures. Wires expand and contract as temperatures change, and over time, those shifts cause loose connections that result in short circuits. Corrosion from age, rust, or outdoor exposure blocks proper electrical flow, causing your system to shut down at random. Frayed insulation is even more concerning — exposed live wires create real fire hazards and electrocution risks.
Short circuits happen when hot wires accidentally contact neutral wires. Ground faults occur when hot wires touch ground wires. Both generate extreme heat, damage breakers, and pose serious fire risks. These are not DIY fixes — they require immediate professional repair.
Tripped Circuit Breakers
Here’s a simple way to think about it. Your AC pulls more amps than your breaker rating allows, and the breaker does its job by shutting off power to protect you. Example: a 20-amp breaker with an AC drawing 30 amps will trip every time. That’s the breaker working correctly.
What you should never do is keep resetting it. Constant resets harm your equipment and can lead to fires.
Safety Precautions
We aim to never miss any detail when it comes to your safety. Before any troubleshooting near your AC’s electrical components, follow these steps:
-
Turn off power at the circuit breaker completely
-
Wear eye protection and insulated gloves
-
Stay away from electrical components in wet conditions
-
Shut down the system immediately if you notice burning smells and call a professional right away

Dirty Condenser Coils
Image Source: CRC Industries
Your condenser coil sits outside in a large metal box, exposed to the elements every single day. Grass clippings, cottonwood fluff, dirt, pollen — it all collects on this unit year-round. And once spring and summer hit, that buildup happens faster than most homeowners realize.
How Dirty Coils Affect Performance
Think of dirt coating your coils like wrapping them in insulation. Heat that should escape into the outdoor air gets trapped instead. What used to take your system 15 minutes to accomplish now takes 25 to 30 minutes. That puts serious strain on your compressor, causes it to overheat, and wears it out well before its time. Compressor replacements are not cheap — and proper maintenance is exactly what prevents that cost.
Cleaning and Maintenance Schedule
Most homes need coil cleaning once a year, ideally in spring before cooling season kicks in. That said, some situations call for twice-yearly service:
-
Homes with pets
-
Properties near construction zones or farmland
-
Households with allergy sufferers
-
Older AC systems
-
Systems running year-round
Monthly visual inspections during cooling season go a long way toward catching debris buildup before it becomes a bigger problem.
Energy Efficiency Impact
Dirty coils can drive energy consumption up by as much as 30%. The compressor has to pump at higher pressures to push heat through all that built-up dirt, which draws more amps and sends your utility bills climbing.

FAQs
Q1. What are the most frequent air conditioning problems homeowners experience? The most common AC issues include the system not blowing cold air, frozen evaporator coils, refrigerant leaks, clogged air filters, drainage problems, faulty capacitors, malfunctioning thermostats, compressor failures, blower motor issues, electrical problems, and dirty condenser coils. Many of these problems stem from lack of maintenance, such as not replacing filters regularly or skipping annual professional tune-ups.
Q2. How can I tell if my AC has a refrigerant leak? Signs of a refrigerant leak include hissing or bubbling sounds near the indoor unit, your home taking longer to cool than usual, the system running constantly without reaching the set temperature, increased humidity indoors, higher electricity bills, ice forming on the evaporator coils, and sometimes a faint sweet odor. You may also notice oily residue around fittings, valves, and refrigerant lines where the leak is occurring.
Q3. How often should I replace my air conditioner filter? Filter replacement frequency depends on the type and your household conditions. Standard 1-inch fiberglass filters need monthly replacement, while pleated filters last 60-90 days. Thicker 4-inch filters can go 3-6 months, and 5-inch filters up to 12 months. However, homes with pets, smokers, or allergy sufferers should check filters monthly and replace them more frequently to maintain optimal performance and air quality.
Q4. When should I call a professional instead of trying to fix my AC myself? You should contact a professional for refrigerant leaks, electrical issues, compressor problems, capacitor failures, and persistent frozen coils. While you can handle simple tasks like changing filters, checking thermostat settings, and clearing debris from the outdoor unit, complex repairs involving refrigerant, high-voltage electricity, or major components require EPA-certified technicians with proper tools and training to ensure safety and compliance.
Q5. What causes my AC evaporator coil to freeze? Frozen evaporator coils typically result from restricted airflow caused by dirty air filters, blocked return vents, or furniture covering vents. Other causes include low refrigerant levels from leaks, dirty evaporator coils themselves, malfunctioning thermostats, or blower motor problems. If your coil refreezes within 24 hours after replacing the filter and opening all vents, you likely have a refrigerant leak that requires professional repair.
