You probably need a repair if your system is:
- Not meeting your indoor comfort expectations.

- Working sporadically.
- Leaking water.

If the AC is running but doesn’t seem to be cooling the house, it could be for many reasons.
- First, check that the thermostat is set to “cool” instead of “fan” mode. (It happens more often than you think!)
- If you are familiar with the condenser drain line, you’ll want to check that to make sure it’s not clogged.
- Also, remember that most AC units can only lower the inside temperature to 20 degrees below the outside temperature on days with extreme temperatures.
Sometimes, these simple checks will fix the problem. If not, you’ll probably want to call in the pros. Some other common issues include dirty condenser coils, frozen evaporator coil (sometimes indicated by frost forming on the outdoor unit) and refrigerant leaks.

If you don’t regularly service your home’s AC system, it will likely cost you more money in the long run. If you think about it, an air conditioning unit is somewhat like a car, a complex mechanical system with many moving parts and electrical components that operate in harsh outdoor conditions.
A regular maintenance plan can save you money and make life easier by:
- Lowering utility costs through increased system performance.
- Catching minor repairs before they become big problems.
- Helping your AC system to last longer.

There’s no question that an air conditioning unit can be loud at times, but a system making obviously weird noises often means there is a problem.
Here are a few sounds you might be hearing and what they may be caused by:
- Loud squealing during outside unit fan startup. Outside blower motors may be malfunctioning.
- Banging. A clue that likely points to a loose or broken part.
- Clicking. Constant clicking sounds may indicate a possible electrical issue.
- Jingling sounds could mean you’re low on refrigerant.
HVAC systems typically make a lot of noises during regular operation. If you have a hunch that something might be wrong, however, it’s better to check it out.
