4 Common AC Problems in Greenville

After decades of helping our South Carolina communities with their HVAC systems and equipment, we have seen just about everything that can go wrong with an air conditioning system. Our experience can help you get your home back to comfortable levels faster.

Signs your AC needs repair include:

  • Air conditioner not blowing cold air — This problem can be caused by a bad compressor, low or leaking refrigerant, or even damaged electrical contacts. If the compressor has gone bad, it will no longer be able to change the state of the outside air, which is how cooling occurs. Many people opt to replace their units altogether since replacing a compressor can be expensive.
  • Air conditioner won’t turn on — This is usually an electrical issue. Something is causing the circuit not to complete itself. Wiring and contacts are the most likely culprits in these situations. The problem could also be caused by a faulty thermostat.
  • Some rooms cooler than others — So long as the unit itself is working, chances are unevenly cooled rooms have to do more with the ductwork. We offer duct repairs and replacements to help your home be more comfortable throughout.
  • Your energy bill has spiked — Have you noticed that your energy bill has gone way up, but your home still isn’t cool enough? Don’t settle for paying more money for less comfort; if your AC is constantly running but isn’t cooling your home, this is a sign that your AC is not operating efficiently and either needs to be serviced or replaced.

Air Conditioning Repair FAQs


If your AC is not getting cool, turn it off and call us for AC repair. If the outdoor unit is starting to freeze, and you continue to run the system, you could cause even more costly damage.


Routine maintenance is vital to protecting your air conditioner and preventing the need for repair. If you do not have regular service done, then your system may get full of dirt and debris. This affects its efficiency and can even lead to repair problems. Investing in AC maintenance is protection against unwanted AC repair.


On average, an air conditioning repair will take between two to six hours. The total time for your repair may vary depending on the type of repair you need. At Waldrop, we strive to work quickly but accurately, so you can get back to enjoying your home fully.


Air conditioners are critical during the hot, muggy South Carolina summers, but did you know that when improperly maintained, they may actually contribute to illness?

Here are some things to be aware of so that you can stay on top of your AC … and your health!

  • Dirty air filters can allow your air conditioner to blow dust, mold, bacteria, and other contaminants around your home. Be sure to replace your AC filters at least every couple of months.
  • Keep your AC temperature reasonable. Not only does this reduce wear and tear on your unit by reducing the amount of time it runs, but it can also alleviate dry skin and nasal passages.
  • Consider adding a whole-home filtration system so that every time you run your AC, you can have peace of mind knowing that you’re breathing clean, healthy air.


It may seem odd, but air conditioners can actually freeze on a scorching hot day. How? Air conditioners work by taking in warm air, using refrigerant to lower its temperature, and then exchanging that cooled air for the warmer air in your home. When some part of that system falls out of balance, the evaporator coil can cause the refrigerant to cool too much. The result is that ice can form on your coil and cause the AC to stop working. The most common cause of AC freezes is restricted airflow due to dirty HVAC filters. If you suspect that your AC has frozen, you will need to turn off the system and allow it to thaw.

Here are some preventative measures you can take to reduce the chance of a frozen AC:

  • Change your air filter regularly (about once a month)
  • Have your refrigerant level checked
  • Inspect your condensate drain for clogs regularly
  • Ensure that all of your supply vents are open
  • Ask your AC technician about increasing the fan speed
  • Never skip your annual maintenance appointment


Have you noticed a leak from your air conditioner? There are many possible causes, and all of them require the attention of a professional AC repair technician. Air conditioner leaks won’t resolve themselves, so make sure to call Waldrop Plumbing – Heating – Air as soon as you notice a problem.

Air conditioner leaks can be caused by:

  • Low refrigerant, which causes the evaporator coil to freeze over and leak condensation into the drain pan.
  • A dirty air filter can also cause an evaporator coil freeze leading to excess water.
  • A clogged condensate drain line can be fixed by using a wet/dry vac to remove built-up dirt, dust, mold, etc.
  • A rusted or damaged drain pan no longer catches condensation and should be replaced.
