Imagine the discomfort of a broken HVAC system during the hottest time of the year. Your air conditioner is never more critical than when the temperatures start heating up outside.

If you notice your AC displaying worrisome signs, you should consider an HVAC system repair.

Read to discover five major signs of a broken air conditioner.

1. Blank Thermostat

The thermostat relays power to the unit’s components to turn them on and off. If you notice your thermostat screen is blank, it has lost power and won’t initiate your unit to run.

It’s a small appliance, but the thermostat serves a vital purpose in the functioning of your AC unit.

Here are the most common reasons the thermostat has lost power and will appear blank:

• Tripped circuit breaker
• Blown low-voltage fuse
• Tripped safety switch
• Bad thermostat

Your HVAC technician can diagnose which issue may be causing the blank thermostat.

2. Warm Air Coming Out of Vents

In the summer, the last thing you want your air conditioner to do is blow warm air into your house. A broken compressor could be the culprit if you notice warm air coming out of your vent.

The compressor is responsible for pumping the refrigerant throughout the system, and the refrigerant is what creates cool air. If the compressor is faulty, the refrigerant can’t do its job.

Warm air could also mean a refrigerant leak. The compressor may be working, but if the refrigerant is leaking out of the system, it will compromise its ability to cool the air.

3. No Air Coming Out

If your unit is on and running, but no air is coming out of the vents, you have a broken blower motor or an iced-up evaporator coil.

The blower motor is responsible for pushing air through the ducts and out through the vents. If it fails, no air will circulate.

If the evaporator coil becomes coated in ice, the ice acts as a barrier to the air being pushed from the blower motor.

4. Can’t Maintain Temperature

If you notice your thermostat isn’t maintaining the set temperature and everything else seems operational, an AC repair technician will explore common causes to pinpoint the problem.

Here are some issues that cause a lack of cooling capacity:

• Dirty evaporator or condenser coil
• Dirty air filter
• Low refrigerant

These problems lead to your unit running longer and working harder, leading to a higher energy bill, and possibly your entire unit shutting down.

5. Air Handler Leaking Water

Your air handler is the part of the unit usually hanging in your garage, attic, or closet. Water stains or dripping or standing water are cause for concern. The issue could be clogged drain lines, a cracked evaporator pan, or a faulty float switch.

Leaking water from your air handler can cause water damage, so it’s important to call for air conditioner repair as soon as you see signs of a leak.
