Trusted Heroes For Every Task

When your air conditioner stops cooling the way it should, it’s natural to wonder whether you’re dealing with a simple fix or a costly repair. Some AC problems are minor and can be resolved with basic maintenance, while others indicate a more serious mechanical issue that requires professional attention.

Bobby Hett

We had a main line drain clog under the house. Russell was our technician and approached the problem from outside the house, working retrograde from a trap in the front yard. I was skeptical but it worked when my efforts with a cable inside the house had failed. He was very professional and pleasant to deal with.  We asked him to install a cleanout closer to the house for future use and we were very satisfied with the work.

Tyler is the best! He came to our parent's house, knew exactly what the problem was, and explained it to us without the typical guesswork. I'd recommend him any time you need a good plumber.

Our technicians are committed to offering reliable and cost-effective HVAC services, including heating repair. If you’re looking for a trusted HVAC company that can help you keep your AC in great shape, look no further than Service Hero. In this post, our HVAC technicians explain how to tell if your AC issue is minor or a bigger problem.

Weak Airflow

Minor Issue

We Provide Professional Plumbing & HVAC Services

Tailored services to meet your specific needs and budget, ensuring optimal performance and comfort.

If the airflow feels weak at the vents, the most common culprit is a dirty air filter. Clogged filters restrict the movement of air through the system and reduce cooling efficiency. Closing too many vents or having furniture block a return vent can also cause mild airflow problems.

Bigger Problem

If changing the filter doesn’t help, the issue may lie in the blower motor, ductwork leaks, or a frozen evaporator coil. These problems can put strain on your system and lead to complete failure if ignored.

Warm Air Coming from the Vents

Minor Issue

Sometimes the thermostat is simply set incorrectly, or the AC is in “fan only” mode. A tripped breaker can also prevent the outdoor unit from running, causing the indoor unit to blow warm air.

Bigger Problem

If the system is running but still blowing warm air, you might be facing a refrigerant leak or compressor failure. Both require professional repair and should be fixed quickly to avoid further damage.

Strange Noises

Minor Issue

A loose screw, rattling grille, or small debris in the outdoor fan can create unfamiliar noises. These are usually simple to resolve.

Bigger Problem

Grinding, screeching, or banging sounds indicate serious mechanical trouble. These noises may come from a failing motor, a broken fan blade, or a damaged compressor. Turning the system off until a technician arrives is the safest choice.

Odd Smells

Minor Issue

A dusty smell when you turn the AC on for the first time in a season is normal. It often disappears within minutes as dust burns off.

Bigger Problem

A musty odor could mean mold inside the system or ductwork. A burning smell may indicate an electrical short or overheating component. Both situations call for an inspection by an AC repair specialist.

System Frequently Turns On and Off (Short Cycling)

Minor Issue

Short cycling can sometimes happen due to a clogged filter or an incorrectly set thermostat.

Bigger Problem

If the system continues to short cycle after basic troubleshooting, the cause could be an oversized AC unit, a failing compressor, low refrigerant, or electrical issues within the system. Ignoring short cycling can greatly reduce the lifespan of your unit. Get in touch with a local HVAC company to inspect the unit and make repairs.
