AC Running but Not Cooling in Phoenix

Do this now

1. Replace a dirty filter and give the system 15–20 minutes.
2. Confirm supply vents are open and return grilles aren't blocked.
3. Look for ice on the copper lines or indoor coil — if iced, turn the system off and switch the fan to On to help thaw.
4. Check that the outdoor unit is powered and the fan can spin freely (power off before touching).
5. Request help online for a contractor match.

Signs to look for

• Supply air only slightly cooler than room air
• System short-cycles (starts and stops often)
• Outdoor unit runs but indoor air stays warm
• Rooms farthest from the air handler are much hotter
• Sudden loss of cooling after a dust storm

What the contractor typically does

Every job is different. The independent contractor you're matched with explains their own process and price. A typical visit often includes:

1. Measure temperatures and inspect airflow
2. Check electrical components and control signals
3. Evaluate refrigerant circuit if symptoms point there (licensed handling)
4. Inspect duct issues when relevant
5. Quote repairs without pressure to replace everything

Phoenix factors

Dirty filters and coils are everyday desert problems. A match gets you a tech who can tell the difference between a simple filter issue and a larger failure — we don't quote parts prices here.
