Air conditioning problems aren’t unusual, and they can usually be attributed to a handful of reasons. While your HVAC contractor can inspect the system and detect the source of the problem, you may be able to figure out what’s going on, too. Here are seven common issues that usually require the attention of an HVAC repair professional.

7 Common HVAC Repair Issues

1. Dirty Air Filter

The unit’s air filter should be replaced at least once every three months. It’s responsible for filtering dirt, dust, and debris and keeping the air inside your home clean. If left unchanged, it causes your air conditioner to work harder to cool your home. This can cause damage to parts and premature aging of the unit.

2. Blocked Air Ducts

Sometimes dust accumulates in the air ducts. In other cases, they may even become temporary homes to rodents or other critters. No matter what the obstruction, it can prevent proper airflow and reduce your HVAC unit’s efficacy. A repairman can determine if cleaning the ducts would be effective.

3. Clogged Registers

HVAC repair professionals recommend checking the air vents, too. These registers, which are usually easy to access on the floor or ceiling, can often become blocked by dust and dirt. In some cases, they’re obstructed by poorly placed pieces of furniture. Dirty or blocked registers also force your system to work too hard, causing unnecessary wear.

4. Faulty Thermostat

Sometimes a malfunctioning thermostat is actually the sole source of your HVAC unit’s problems. However, this is good news, because it typically proves to be a very simple fix. In some cases, a new battery is all that’s needed. In other instances, an HVAC repair expert may need to check the anticipator and other parts to make sure they’re working correctly.

5. Low Refrigerant

If the air conditioner is blowing hot air or you hear an odd bubbling noise from the unit, it’s likely that it’s low on refrigerant. Your technician can resolve this, but first they’ll inspect the system to make sure that there isn’t a leak in the lines. If there is one, an HVAC repair will be necessary before any more refrigerant is added.

6. Improper Size

It’s very important that your residential HVAC system is the right size. Units that are too large can’t efficiently cool homes, and can actually cause the air to feel warm and stuffy. When you call for a repair, the technician will be able to determine if your unit is too small, and may recommend an appropriate alternative.

7. Unit Obstruction

Check the space around the outdoor unit. It’s not unusual for it to become obstructed by basic outdoor debris, like branches, leaves, and dirt. When that happens, it can cause the system to overheat and prevent it from cooling properly.
