Why Is My Central AC Running But Not Blowing Air? — 3 Reasons
Here are three common reasons why your AC unit isn’t blowing air as it should:
Clogged Condenser Unit
When your AC stops blowing air, debris accumulation on its condenser unit could be to blame.
Debris can accumulate on it, restricting airflow and potentially leading to internal damage. To keep this from happening, regularly clean the area around it and trim back any plants or trees that contribute to it becoming blocked with debris build-up; or contact an HVAC technician specializing in coil cleaning to get this problem under control as quickly as possible.
Low Refrigerant Levels
Insufficient refrigerant levels can prevent your AC from blowing cool air. This could indicate that there's a leak somewhere within its system that requires professional repairs; DIY attempts at repair could even do further harm than good and may void its warranty, so hiring an expert technician to identify and address these problems safely is always advised.
Dirty Air Filter
A dirty air filter can be the cause of your AC not blowing air properly. Over time, dust and debris buildup on its filter surface clog it, restricting airflow and decreasing cooling capacity. Therefore, regular replacement should ensure maximum performance without unnecessary costs for repairs or maintenance services.
Faulty Thermostat
An improperly calibrated or malfunctioning thermostat can drastically disrupt airflow to your AC, leading to temperature inconsistencies and random system cycling. Reset it by turning off power for both units immediately before rebooting; otherwise, consult a professional HVAC technician for accurate diagnosis and repair services.
Troubleshooting Tips
Here are a few troubleshooting tips that may help resolve the AC not blowing air issue:
Clean or Replace Air Filter
Before taking action to change or clean an air filter, switch off all power sources. Washable filters can be rinsed under running water before drying off, while disposable ones should be thrown out immediately.
Check Refrigerator Refill Levels
For best results, it is advisable to entrust this task to an expert technician, who can safely check and recharge refrigerant levels as soon as they drop below acceptable threshold levels. A low level may signal leaks that must be fixed prior to adding more refrigerant.
Adjust Thermostat Settings
When setting your thermostat to "cool," and your desired temperature lower than that of room temperature, ensure all heat-emitting appliances are kept away from thermostats to achieve accurate readings.
Clean the Condenser Unit
Switch off the power for your AC and remove loose debris using either a soft brush or vacuum cleaner. Next, use a garden hose with gentle pressure spraying water through its fins for further cleanup of debris that remains. In cases of persistent clogging or damage, seek professional assistance as soon as possible.
When to Call in Professionals
If your AC system has suffered severe damage and troubleshooting efforts, haven't managed to address its problems, or there have been repeated issues, calling in professional technicians may be necessary in order to get expert attention for these underlying problems as soon as possible - which will save money in more costly repairs in the long run.
Licensed technicians have expertise diagnosing and fixing such problems quickly; so call one today so they can keep you out of more expensive trouble in future!
Why Is My Central AC Running But Not Blowing Air? — Conclusion
At its core, simple maintenance strategies such as replacing air filters regularly or cleaning/changing refrigerant levels may often solve your AC not blowing air problem. But should this persist or there be severe damage, professional assistance should always be sought to avoid costly repairs while also keeping performance optimally.
Keeping regular check-ups of your HVAC system will protect it and prolong its service life and performance for as long as possible.
