Common AC Problems We Fix
Air conditioners can break down in a variety of ways. Some are obvious, while others are subtle. Whether your system stops altogether or just doesn’t cool like it used to, we’re trained to diagnose and fix the issue quickly and correctly.
Our technicians are equipped to handle a wide range of AC repair problems, including:
- Frozen evaporator coils – Usually caused by airflow problems or low refrigerant, these can freeze your system into failure.
- Weak airflow or poor cooling – Often a sign of a blocked filter, duct issue, or failing blower motor.
- Warm air from vents – A common sign your system isn’t cycling properly or has compressor trouble.
- Loud or strange noises (buzzing, grinding, hissing) – Noises can mean electrical issues, loose parts, or internal wear.
- Thermostat issues – If your thermostat isn’t responding or reading correctly, it can throw your whole system off.
- Constant cycling or shutdowns – Could point to dirty coils, faulty sensors, or even oversized systems.
- Water leaks or frozen lines – Usually tied to drainage or refrigerant issues.
- Tripped breakers or electrical faults – These can cause intermittent cooling or full shutdowns.
- Blower motor problems – Without proper air movement, your home won’t cool evenly.
- Refrigerant leaks or low levels – Not only bad for performance, but also potentially harmful to the environment.
Whatever the issue, Deljo’s team has fixed it. Most problems can be resolved in a single visit, getting your home cool again without delay.

Before You Call for Things to Check First
Sometimes the fix is simple, and you can save yourself a service visit just by checking a few things. We’re happy to help, even if that means you don’t end up needing us today.
Before you schedule your AC repair, take a quick look at:
- Thermostat Settings – Make sure your system is set to “cool” and the temperature is set below the current room temperature.
- Air Filter – A dirty or clogged filter can restrict airflow and freeze the system.
- Circuit Breakers – If your breaker has tripped, your system won’t turn on at all.
- Outdoor Unit – Leaves, dirt, and debris can block airflow and cause the AC to overheat.
- Vents and Registers – Blocked or closed vents can affect cooling efficiency throughout the home.
Still having issues? Don’t worry. Our expert team is just a call away, and we’re ready to step in when DIY doesn’t cut it.
