Air Conditioning Repair Services in Seffner, FL

Red Flags That Need Immediate Attention

Some HVAC problems signal immediate danger or risk of serious damage. If you notice any of the following warning signs, your system likely requires emergency service and should not be ignored.

• Burning Smells

• Complete Loss of Cooling

• Water Actively Leaking

• Loud Grinding or Screeching

• Uneven Home Cooling

• Humidity Problems

Common AC Problems We Repair

AC Won’t Turn On

Symptom: Your thermostat shows it’s calling for cooling, but nothing happens when the system should start.

Typical Causes:

• Tripped circuit breaker cutting power to the unit
• Failed capacitor preventing compressor or fan motor startup
• Faulty thermostat not sending proper signals
• Blown fuse in disconnect box near outdoor unit
• Defective contactor with pitted contacts

Our Solution: We trace the electrical path from thermostat through controls to motors, identifying exactly where power delivery fails. Most of these repairs complete within an hour.

AC Runs But Doesn’t Cool

Symptom: The unit operates normally with fan spinning and sounds running, but your home stays warm and humid.

Typical Causes:

• Low refrigerant from leaks in coils or line connections
• Frozen evaporator coil blocking airflow
• Failed compressor that runs but doesn’t pump refrigerant
• Extremely dirty outdoor coil restricting heat rejection
• Incorrect thermostat location sensing wrong temperature

Our Solution: We measure system temperatures and pressures at multiple points to pinpoint whether the problem is airflow-related, refrigerant-related, or mechanical failure in the compressor.

AC Freezes Up

Symptom: Ice forms on copper lines or indoor coil, eventually blocking all airflow and cooling.

Typical Causes:

• Restricted airflow from clogged filters or blocked returns
• Low refrigerant causing temperature drop below freezing
• Failing blower motor moving insufficient air across coil
• Dirty evaporator coil restricting airflow
• Closed or blocked supply vents throughout home

Our Solution: After thawing the ice (which takes 1-2 hours), we identify and correct the airflow or refrigerant issue preventing proper heat exchange.

Water Leaking Inside

Symptom: Water drips from ceiling near air handler, pools under indoor unit, or appears around supply vents.

Typical Causes:

• Clogged condensate drain line backing up water
• Cracked or rusted drain pan under air handler
• Frozen coil melting excessive water faster than drain handles
• Disconnected drain line at coupling points
• Failed condensate pump not removing water

Our Solution: We clear drain blockages, repair or replace drain pans, and verify proper drain line slope and connections. Most drain issues resolve quickly once identified.

Weak Airflow from Vents

Symptom: Little air comes from supply registers even though the system runs, or only some rooms receive adequate airflow.

Typical Causes:

• Clogged air filter restricting return air
• Failing blower motor running at reduced speed
• Ductwork disconnections losing air in attic
• Undersized or crimped ducts limiting flow
• Dirty blower wheel reducing air movement

Our Solution: We measure static pressure and airflow at multiple points, identifying restrictions in the air delivery path and correcting them.

AC Short Cycles

Symptom: The system turns on, runs for a few minutes, shuts off, then repeats continuously without cooling properly.

Typical Causes:

• Oversized equipment for your home’s cooling load
• Failing thermostat with faulty temperature sensor
• Refrigerant overcharge causing high pressure shutdowns
• Dirty outdoor coil triggering safety cutoffs
• Failing compressor with internal problems

Our Solution: We monitor system operating cycles and pressures to determine whether short cycling results from equipment sizing, controls, or mechanical issues.

Strange Noises

Symptom: Grinding, squealing, banging, or buzzing sounds coming from indoor or outdoor units.

Typical Causes:

• Loose fan blades hitting housing or debris
• Failing compressor bearings making grinding sounds
• Worn blower motor bearings causing squealing
• Loose panels or access doors vibrating
• Contactor chatter from weak coil voltage

Our Solution: We identify the sound source and determine whether it indicates immediate danger requiring shutdown, or a developing problem that can be scheduled for convenient repair.

High Electric Bills

Symptom: Your power bills have increased significantly despite similar usage patterns and thermostat settings.

Typical Causes:

• Efficiency loss from dirty coils and restricted airflow
• Refrigerant leak causing system to run continuously
• Failing compressor drawing excessive amperage
• Duct leaks wasting cooled air in hot attic
• Aged equipment naturally losing efficiency

Our Solution: We measure actual system performance and electricity consumption, comparing against baseline efficiency to identify specific causes of increased energy use.

Most Common Air Conditioning Repair in Seffner

Capacitor Replacement

Cost Range: $150-300 Time Required: 30-60 minutes

Capacitors fail frequently in Florida’s heat. They provide the electrical boost needed to start compressor and fan motors. When capacitors weaken, motors struggle to start or won’t run at all.

Refrigerant Leak Repair & Recharge

Cost Range: $300-800 Time Required: 1-3 hours

Small leaks develop in coils, line connections, or valve stems. We locate leaks using electronic detectors or UV dye, repair the leak point, evacuate the system, and recharge to proper levels.

Contactor Replacement

Cost Range: $150-250 Time Required: 30-45 minutes

Contactors are electrical relays that switch power to your compressor and fan. Contact points pit and burn from repeated switching, eventually failing to make solid connections.

Blower Motor Replacement

Cost Range: $400-700 Time Required: 2-4 hours

Indoor blower motors wear out from continuous operation. Bearings fail, causing noise and reduced airflow until the motor stops completely.

Condensate Drain Line Cleaning

Cost Range: $100-200 Time Required: 30-60 minutes

Algae and debris clog drain lines, triggering safety switches that shut down your AC to prevent water damage. We clear blockages and treat lines to slow future growth.

Compressor Replacement

Cost Range: $1,500-2,500 Time Required: 4-8 hours

Compressors are the heart of your AC system. When they fail, repair costs often approach half the price of a new system, making replacement worth considering.

Evaporator Coil Replacement

Cost Range: $800-1,500 Time Required: 4-6 hours

Indoor coils develop leaks or corrosion damage. Replacement involves recovering refrigerant, accessing the coil (sometimes requiring air handler removal), and recharging the system.
