Common HVAC Problems and How to Address Them

HVAC systems are crucial for maintaining comfort in our homes, but they can encounter various issues over time. Here’s a rundown of some common HVAC problems and tips on how to handle them.

Refrigerant Leaks

Refrigerant leaks can be problematic, often necessitating an upgrade. Different refrigerants can be expensive to refill, and finding the leak can be challenging. For older systems, repair might not be practical. Routine professional checks are recommended to prevent and address leaks.

Thermostat Errors

Modern thermostats (T-stats) often display error codes to prompt a service call. If you see an error code, it’s best to contact a professional for diagnosis and repair.

Clogged Drains

Flushing the condensate line is a standard part of HVAC maintenance. Clogged drains are common in all HVAC systems, and regular professional maintenance can prevent issues.

Dirty Filters

Changing filters is crucial for the optimal performance of HVAC systems. Regular filter changes by a professional can ensure your system runs efficiently.

Dirty Coils

HVAC coils need chemical cleaning every 3-4 years to maintain peak operation. Schedule routine professional cleanings to keep your system in top shape.

Duct Leaks

Pressure testing ductwork is mandatory for new system installations in Southern California. Regular professional checks can help detect and seal duct leaks, improving system efficiency.

Clogged Evaporator Coil

A clogged evaporator can cause multiple HVAC issues. Routine professional maintenance can prevent these problems.

Compressor Issues

The number of amps a compressor pulls indicates its performance and potential future failures. Regular professional inspections can catch these issues early.

Poor Airflow

Poor airflow in a new system suggests installation problems, while in older systems, it indicates a need for professional evaluation.

Loud and Unusual Noises

If your HVAC system makes unusual noises, stop using it immediately and call for service. This can prevent further damage.

Water Leaks

Water leaks are serious and can cause significant damage. Stop running the system and contact a professional immediately.

Blown Fuses

Blown fuses usually signal a more significant problem. Have a professional inspect your system to identify and fix the underlying issue.

Blower Problems

Blower motors need deep cleaning every 3-4 years. Routine professional maintenance can ensure they operate correctly.

Ignition Problems

Ignition issues are often resolved with regular professional maintenance visits.

Circuit Breaker Trips

If your circuit breaker trips frequently, it’s a symptom of a bigger problem. Professional inspection is necessary to identify the cause.

Air Conditioner Freezes Up

A frozen air conditioner should not be used. Call a professional to prevent water damage and further issues.

Frozen Evaporator Coils

Similar to a frozen air conditioner, frozen evaporator coils require immediate professional attention to avoid water damage.

Increased Humidity

If your system increases humidity, stop using it and call a professional. This can indicate significant problems that need prompt attention.

Routine maintenance and professional inspections are key to keeping your HVAC system running smoothly and efficiently. Don’t hesitate to call in the experts to address these common issues.
