Symptoms of AC Issues

Sometimes air conditioners can behave oddly—particularly if they are older systems. Over time you get used to your HVAC system and know what to expect from it. There may be times, however, when you notice a strange sound or unexpected quirk. Here are some common AC problems that go beyond quirks, so you know when to request air conditioning service in Northbrook, IL.

No Cool Air

One of the most noticeable problems with cooling systems is no cold air coming out of the vents, or no air at all. If your AC is not blowing cold, call Deljo Heating & Cooling immediately. We will quickly and professionally diagnose and repair this problem for you.

Weak Air Flow

Sometimes this can be caused by a dirty air filter, but there are other potential causes too. If your AC’s air flow is weak or you can’t tell if it’s even running, we will be able to figure out what’s going on and quickly return your home to comfort.

Water or Moisture Issues

If your air conditioning unit starts collecting moisture or you see water pooling, the problem may be with the refrigerant. It can also indicate an issue with the condensate pump or other problems. Deljo Heating & Cooling is dedicated to your comfort, so just call us.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
