Uncommon AC Issues & What’s Causing Them

You’re probably familiar with the signs of common problems with air conditioners. Perhaps you’ve even called us when your AC’s evaporator coils froze up or it was emitting lukewarm air. These are all situations when it’s obvious that it’s time to call us to diagnose and fix the issue. But there are uncommon AC issues that aren’t as well known and don’t occur as often.

Let’s go over some more unusual issues that you might come across someday as a homeowner in Hammond, LA. That way you won’t be left wondering whether you should call for AC repair or if it’s completely normal.

Strange Thumping Sound

Is your AC unit making a thumping noise? Or perhaps you hear the screeching sound of metal on metal. These sounds can be quite loud and obnoxious and when they’re constant, they’re quite concerning. It’s likely that your blower fan has come loose and is thumping against other metal parts. Give us a call to get this fixed right away.

Rodent Damage

Signs of a rodent infestation usually become evident in the spring when you first turn your AC on. That’s because rodents like to nest in your home over the winter. Your cozy, warm HVAC system has a lot of nooks and crannies where they can get in, build nests, and shelter for the winter. They particularly like setting up home in your ductwork.

Signs of rodents in your HVAC system include the following. 

  • Scratching, gnawing, and scurrying noises from the unit itself or in the vents/ductwork.
  • Droppings are an obvious sign of a critter infestation. You’ll see them in or around the HVAC unit.
  • The smells that come from mouse urine and feces or their dead bodies are bad. They could smell like ammonia or just be an unpleasant, pungent scent. You’ll notice these coming from your vents.
  • Damage to the unit: Mice like to chew on things and that includes just about anything in your HVAC system such as wiring, insulation, and even the ductwork itself. As a result, your HVAC system might cause a major malfunction or a complete breakdown.

Damage from Leaks

We know it may seem weird to read about water damage in a blog about air conditioning. But unfortunately, it’s a possibility. Your AC works by removing heat and moisture from your home’s air. And all that accumulated moisture needs to go somewhere. That’s what the condensate drain line is for. 

This drain line has a narrow opening that can easily become clogged by a buildup of dirt, debris, and even mold. When this happens, the water has nowhere to go and will back up and leak out, overflowing the drain pan that’s only meant to hold a small amount of liquid. This pan itself can develop cracks and corrosion which can also cause leaks. When this happens, the result is water damage to the nearby floors and walls of your home.

Whether you have the strangest AC issue or one that’s run-of-the-mill, give us a call for fast and professional service.
