Why is my AC blowing warm air?
Common causes include a dirty filter, a thermostat set to fan only, a frozen coil or a problem with the outdoor unit.
HVAC service
HVAC problems can change how warm or cool a home feels, how much air reaches each room, how loud the system runs, and whether it starts, stops or cycles as it should. Find the symptom, then find the service.

Now Air AC Repair is a residential heating and air conditioning company at Delray Beach, FL. We work on the equipment installed in the home: condensers, air handlers, furnaces, heat pumps, thermostats and ductwork.
Every visit starts with the symptom you noticed — warm air, no heat, weak airflow, noise or short cycling — and ends with the system running as it should. We explain what we find before any work begins, and we are on the phone seven days a week.
Cooling problems show up as warm rooms, long run times or weak air. These are the areas covered in an AC visit.
Ignition, burners, heat exchanger and blower working in the right order.
Heating in cold weather, defrost cycles and reversing valve function.
Warm air moving through ducts and out of every register.
Correct signals between the thermostat and the heating equipment.
Cleaning and inspection before the heating season starts.
Repairs cover the equipment below. Tap a row to see how it fits in the system.
Cool and dehumidify air for the whole home through one duct system.
Burn gas or use electric elements to heat air that the blower sends through the ducts.
Move heat indoors in winter and outdoors in summer with one system.
Indoor units that hold the blower and coil to circulate conditioned air.
Sense room temperature and tell the equipment when to start and stop.
Release heat from the refrigerant using a fan and coil outside the home.
Carries air to each room. Leaks and blockages change what reaches the vents.
Common causes include a dirty filter, a thermostat set to fan only, a frozen coil or a problem with the outdoor unit.
Closed or blocked vents, duct leaks and uneven insulation can leave a room out of balance.
Check the thermostat mode and filter first. Ignition, gas supply or safety switches may also stop a furnace.
A clogged filter, blocked return, failing blower motor or crushed duct can reduce air at the vents.
Short cycling can come from an oversized system, dirty filter, airflow restriction or a thermostat issue.
Dead batteries, loose wiring or a tripped switch can leave the display blank or unresponsive.
Describe what the system is doing and when it began.
Look at the equipment, airflow and controls.
Match the findings to the cause of the symptom.
Repair or adjust, then confirm the system runs properly.
