Though it is not difficult to tell if your heating, ventilation, and air conditioning (HVAC) unit needs repairs, most people think it is okay to put off having their unit cleaned or repaired. However, these symptoms can be a warning to bigger, more extensive problems. If your HVAC unit is showing any of the following signs, call an HVAC technician immediately to avoid any serious problems.

 

1. Dust

When your HVAC system needs repairs or cleaning, one of the most noticeable signs is the puff of dust that comes from the unit when it turns on. Normally, properly functioning units will filter out the dust. Visible dust, on the other hand, is a symptom of dusty air registers that need to be cleaned.

 

2. Visible Debris

Aside from seeing some dust emitted from the unit, if your home or workplace has a visible layer of dust and your allergies seem to be off the charts, your HVAC system may be in need of deep cleaning. Though you can remove dust and grime from the filter, the inner duct-work might also need vacuuming and sanitation.

 

3. Odor

Another telltale sign that your HVAC needs cleaning or repairs is an odd smell. When something smells but you can’t find the cause in the garbage bins or anywhere else, it might be coming from the HVAC unit. Look inside the HVAC unit or have a certified technician check the air ducts for any trapped debris, mold, or mildew that might be emitting odors.

 

4. Mold or Mildew

Sometimes, when your air ducts are neglected for a long time, it is possible to see black or brown mold and mildew growing from the inside or around the air registers. However, when this happens, you usually have more than just a mold problem. Yet, if you are sure that the mold or mildew is the only issue, then you can vacuum, sanitize, and deodorize the unit.

 

5. Poor Air Flow

Clogged filters, blockages, or a failing compressor could all be causes for a lack of airflow. Since there’s a bit of uncertainty with the origin of poor air flow, you need to call in a professional HVAC technician for a tune-up.

 

6. Thermostat Problems

The thermostat is the brain of the AC unit. If the HVAC system won’t turn on or if it runs at odd intervals, cannot accurately gauge temperatures, or shows other electrical problems, you should have a HVAC tech look at the thermostat.

 

7. AC Blows Warm Air

Not much explanation needed for this one. If you live in a place where summer is unbearable, and your AC is blowing warm air despite the cool temperature on the thermostat, you might have a Freon issue or something else going on.

 

8. Moisture or Humidity

A part of the HVAC unit is specially designed to reduce moisture in the household. Though some regions are more humid than others, if you suddenly notice more moisture than usual, the HVAC unit might be in need of repairs or cleaning.

 

9. Noises

Whistling, grating, grinding, screeching, and banging are all noises that reveal something amiss in the HVAC unit. If the AC unit is making noises, it could be a sign of clogged filters or debris trapped inside the system. Have a professional technician diagnose the problem as soon as possible.

 

10. Electric Bill Doubles

A power pill that suddenly doubles or triples without any corresponding increase in how often you turn on your appliances could be a sign that your HVAC unit isn’t functioning properly. Regardless of the reason, your AC unit will need repairs.
