If you've called Rockwall, TX, home for any time, the chances are good you rely heavily on your air conditioning system, especially during the scorching summer months. When your AC unit isn't working as it should, it can make your home uncomfortable and lead to costly repairs if ignored.
Let's discuss some of the most common issues that impact an air conditioners performance:
1. AC Blowing Warm Air - Common AC Problems
Low refrigerant levels or a problem with the condenser unit can cause your air conditioning unit to blow warm air. Refrigerant leaks are among the most common culprits of unexpectedly hot air, significantly reducing the efficiency of your system.
How to Troubleshoot:
Check your thermostat settings to ensure it's in "cool air" mode.
Call a licensed HVAC technician for professional AC repair assistance if you suspect the refrigerant is low.
2. AC Won't Turn On
If your air conditioning unit is having trouble starting, a tripped circuit breaker or a more complex issue with the system's wiring could be causing these common AC problems.
How to Troubleshoot:
Check the breaker box for a blown fuse or tripped circuit. Reset them if needed.
Check the batteries in your thermostat and confirm you have the setting to cool.
For wiring issues, contact an HVAC professional to inspect and safely repair your unit.
3. Weak Airflow
Clogged or dirty air filters, blocked vents, and blower fan problems often cause weak airflow. These issues can make it harder for your AC to cool your home and, in turn, increase your energy demands.
How to Troubleshoot:
Regularly replace air filters. Ideally, every 3 months.
Check that all vents and registers are open and unobstructed.
Have your blower motor inspected if the issue persists.
4. Unusual Noises
Loose belts, a malfunctioning compressor, a struggling fan motor, or other mechanical problems can cause your AC unit to grind, squeal, or make banging noises.
How to Troubleshoot:
To prevent further damage, turn off your unit.
Schedule a professional inspection to troubleshoot and fix the problem promptly.
5. Water Leaks Around the Unit
Water pooling around your AC could indicate a clogged condensate drain line or an evaporator coil problem.
How to Troubleshoot:
Use a wet/dry vacuum or call a professional to flush the blockage.
Check for frozen coils, which may require turning off the system for them to thaw out.
Preventative Maintenance for Your AC System
The best way to avoid AC problems is through regular maintenance. Here are some tips to keep your system running smoothly:
Change Filters Regularly: Clean filters improve airflow and efficiency.
Clean the Outdoor Unit: Remove debris and ensure the area around the condenser unit is clear.
Schedule Annual Tune-Ups: A professional inspection can catch small problems before they become costly repairs.
Check Refrigerant Levels: Low refrigerant reduces cooling efficiency and can damage your system.
