AC not cooling in the Tampa Bay outer ring

The repairs behind a warm house run from a median $310 to $3,000, and the first four causes cost nothing to check.

What the job is and when you need it

There are two different problems under this one complaint, and telling them apart saves money. If the fan blows but the air is only lukewarm, the cooling side has an issue: airflow, refrigerant, a coil or a compressor. If nothing runs at all, it is a power or control issue and our page on an AC that will not turn on applies instead.

The cheap causes come first because they are common and free to rule out: a clogged filter, a thermostat set to the wrong mode or with dead batteries, an outdoor unit choked by debris and a tripped breaker. Our troubleshooter walks through each. Only when all four check out does a pro visit make sense, and that is where the diagnostic fee of $190 (62 reports) begins.

After the free checks, the cost ladder is steep. A capacitor is a median $310. Low refrigerant means a recharge at $690 or a leak repair at $1,320.

A compressor or evaporator coil each sit near $3,000. ENERGY STAR lists cleaning both coils and checking the refrigerant level as yearly technician tasks (ENERGY STAR checklist).

Where this job sits in the system

AC not cooling: the parts this job touches
AC not cooling: the parts this job touchesA cross-section of a house. Indoors: a wall thermostat, an indoor unit in a closet with an air filter, blower and evaporator coil, supply ducts in the attic with ceiling vents, a condensate drain line that exits through the wall, and a breaker panel. Outdoors: the condenser unit on a pad, joined to the indoor unit by two refrigerant lines and fed through a disconnect box. Highlighted on this page: Thermostat; Air filter; Indoor unit: blower and evaporator coil; Outdoor unit: compressor, fan and condenser coil; Breaker panel and outdoor disconnect.
  1. Thermostat on this pageThe wall control. It tells the system when to run.
  2. Air filter on this pageCatches dust before the air reaches the blower and coil.
  3. Indoor unit: blower and evaporator coil on this pageThe blower moves the air; the cold coil cools it.
  4. Ducts and ventsCarry cooled air to the rooms and bring return air back.
  5. Condensate drain line, pan and float switchCarries off the water the coil pulls out of the air.
  6. Outdoor unit: compressor, fan and condenser coil on this pageMoves the heat from your house to the outdoors.
  7. Breaker panel and outdoor disconnect on this pageThe power feed to the system, and its local shut-off.
  8. Refrigerant linesTwo copper lines that link the indoor coil to the outdoor unit.

Simplified drawing, not to scale. Real systems vary: the indoor unit can sit in an attic or closet, the ducts can run in the attic or under the floor. Original illustration, not a photo.

Doing the math

Do the four free checks before paying anyone. If a pro is needed, ask for the failed part by name.

A quote for a recharge with no leak search is a bandage, because refrigerant does not get used up: a system low on it has a leak. A median recharge of $690 against a median leak repair of $1,320 shows what is being skipped.

Check these yourself first

Our page for this symptom ranks six causes, gives safe steps for the first four and marks the refrigerant and capacitor causes as hard-line, with no repair steps.

Questions people ask

Can I add refrigerant to my AC myself?

No. Section 608 of the Clean Air Act bars venting refrigerant while servicing AC equipment (EPA Section 608), and technicians who service refrigerant equipment must be certified (EPA 608 certification). A system that needs refrigerant also has a leak.

Why is my AC running but not cooling?

Most often airflow or power to a component: a dirty filter, a blocked outdoor unit, a wrong thermostat mode, or a failed capacitor. Low refrigerant from a leak is the other big one. Check the first four yourself, then call a pro for the rest.

How much does it cost when an AC is not cooling?

It depends on the cause. Reported medians: diagnostic fee $190, capacitor $310, recharge $690, leak repair $1,320, compressor $3,000, evaporator coil $3,000.

Why is my AC freezing up?

A coil freezes when too little warm air crosses it or too little refrigerant is in it. A dirty filter or blocked vents is the free cause to rule out. If ice returns after that, the refrigerant or blower is the suspect, and both need a technician.

These questions come from the topic clusters below in our research on 2,095 mined questions (Refrigerant, capacitor, compressor, parts (DIY repair): 55; AC not cooling / blowing warm air: 54; Repair / service cost and quotes: 23; AC freezing up / iced coil: 31).
