AC Blowing Warm Air
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Low Refrigerant
A leak reducing cooling capacity.
Dirty Condenser
Restricted heat rejection outdoors.
Failing Compressor
The component that actually does the cooling.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Is it safe to keep running the AC like this?
Running low on refrigerant can damage the compressor over time — worth having it checked soon.
Could it just be the thermostat?
Possible, but less common — a technician checks thermostat function before assuming a refrigerant issue.
