Answers to Common Questions
View All FAQsWhy Is My AC Running But Not Blowing Cold Air?
An AC that runs but isn’t blowing cold air usually has an airflow blockage, low refrigerant, a control setting issue, or a problem at the outdoor unit. The most common cause is restricted airflow from a dirty filter or coil, which lets the fan move air without removing heat. If airflow and settings are fine, a refrigerant leak or a failed compressor/condensing fan is likely and needs professional repair. We see this often in Castle Rock homes during cottonwood season when filters plug fast. A quick field clue: if the outdoor fan spins but the air out the top feels only mildly warm, the compressor may not be engaging. We offer same-day service and 24/7 emergency help.
Try these quick checks before calling:
- Set thermostat to Cool and fan Auto, lower setpoint 5°F, and confirm it isn’t on Hold.
- Replace/clean the return filter.
- Clear debris around the outdoor unit and listen for the compressor.
- If you see frost on the lines, turn the system off to thaw.
If basic checks don’t restore cooling, schedule a diagnostic so a licensed tech can test refrigerant charge and electrical components safely. <br/> Updated: 2026-03-31 <br/> Need help in Castle Rock, CO? Call (720) 994-7055 or book online.

HVAC repairs feel expensive because they require licensed, skilled technicians, specialized parts, and thorough diagnostics, often on short notice or 24/7. Complex systems (furnaces, AC, ductless) take time to test, clean, and calibrate. Same-day or emergency service can add cost. In the Denver and Littleton area, we provide transparent, upfront pricing and options, with financing available. Our Home Care Club helps control costs with a 10% repair discount, priority service, and two free filter changes.
Quick ways to lower costs:
- Schedule routine maintenance.
- Join the Home Care Club.
- Request an upfront estimate and options.

Same-day HVAC repair from Brothers Plumbing, Heating, and Electric is priced after an on-site diagnostic, with a transparent, upfront estimate provided before any work begins. Most of the cost typically comes from the parts needed and the labor time to access and fix the failed component. Technicians serving the Denver metro, including Aurora, provide clear estimates after a full-system check focused on root cause, not quick patches. Seasonal “$50 Off Work Performed” offers may apply to qualifying HVAC repairs; ask when you schedule.
Typical cost drivers we confirm during diagnosis:
- Diagnostic visit and full-system inspection
- Parts such as motors, capacitors, valves, or control boards
- Refrigerant recovery and recharge when required
- After-hours or emergency timing that can affect labor rates
For an exact price today, schedule a diagnostic so we can test the system and quote the repair before any work starts. <br/> Updated: 2026-05-25 <br/> Need help in Aurora, CO? Call (720) 994-7055 or book online. “Chris M. At Brothers came to fix our furnace.” — Chris M.
