| Loud or strange noises | Loose parts, failing fan motor, worn bearings, electrical buzzing | Fan motors, compressor, mounting, electrical connections |
| Short cycling | Dirty filter, thermostat issue, oversized system, refrigerant or electrical fault | Thermostat, airflow, system sizing, electrical |
| Weak airflow | Clogged filter, failing blower motor, duct leaks, frozen coil | Blower, filter, coil, ductwork |

If your AC runs but the house stays warm, the cause is usually airflow, refrigerant, or an electrical part. We check the filter, coils, blower, refrigerant pressures, capacitor, and thermostat, then explain what we found before we repair anything.
Warm air from the vents often points to a failed capacitor, a refrigerant leak, a dirty coil, or a compressor problem. Set the thermostat to AUTO and check the filter. If the air stays warm, call us so a small repair does not turn into a bigger one.
Water around the indoor unit is most often a clogged condensate drain, a cracked drain pan, or a frozen coil melting. Turn the system off to limit water damage and call us. In Florida humidity, drain lines can clog quickly.
Ice on the coil or refrigerant line means airflow is restricted or refrigerant is low. Turn the AC off and set the fan to ON so the ice can melt. Do not chip the ice. Then call us to find the cause.
Check the thermostat and the breaker first. If the system still will not start, the cause may be a failed capacitor or contactor, a tripped drain safety switch, or a control board fault. We test each part so we replace only what has failed.
Banging, squealing, grinding, and buzzing each point to different parts. If the noise is loud or metallic, turn the system off and call us before a small repair becomes a motor or compressor replacement.
An AC that turns on and off every few minutes wastes energy and wears out parts. Causes include a dirty filter, thermostat problems, low refrigerant, electrical faults, or an oversized system.
Low airflow can come from a clogged filter, a failing blower motor, duct leaks, or a frozen coil. We trace the airflow from the return to the vents to find where it is lost.
A sudden rise in your electric bill can mean a failing motor or capacitor, a dirty coil, low refrigerant, or leaking ducts. We test system performance and show you what is wasting energy.
Heat pumps cool in summer and heat in winter, so one failed part can affect both seasons. We repair heat pumps from all major brands, including capacitors, fan motors, defrost controls, reversing valves, and refrigerant problems.

Common causes are a dirty filter or coil, low refrigerant, a failed capacitor, or a compressor problem. Set the thermostat to AUTO and check your filter. If the air stays warm, turn the system off and call us so we can diagnose it before more damage is done.
Cost depends on the part and the labor needed. We give you an upfront written estimate before any work begins, and there is no service call fee when you schedule a repair.
Ice usually means restricted airflow or low refrigerant. Turn the AC off and run the fan so the ice melts, and do not chip it off. Then call us to find the cause.
The most common cause is a clogged condensate drain. A cracked drain pan or a frozen coil melting can also cause leaks. Turn the system off to prevent water damage and call us.
A good rule of thumb is to multiply the repair cost by the age of the unit. If that number is more than the cost of a new system, replacement usually makes more sense. Systems over 10 to 12 years old that need a major repair are strong candidates for replacement. We will give you an honest assessment of both options.
