Your AC Isn’t Blowing Cold Air: Now What?

It’s the hottest day of the year and the worst has happened: your air conditioning system stopped blowing cold air. Now what do you do? The first step is to call a trusted HVAC technician in Eastpointe so you can get on their schedule of calls ASAP. The second thing you should do is read our blog for the most common reasons this is happening to you.

Whether your AC quit blowing cold air altogether or it’s just not being consistent, there could be many things to blame. From dirty air filters to blocked registers, we’re here to give you some insight.

1.  Dirty Air Filters

Cold air can’t properly infiltrate your home if the air filter is clogged with dirt, dust, and foreign debris. All that stuff makes the unit cool unevenly, which leaves some rooms too cold and other rooms too warm. Blocked filters can trap pockets of cold air within the coils, leading to icing,then melting, thenwater damage.

To prevent this from happening, be sure to change your AC filter every few months, or more frequently if you have pets or live near a construction site or high traffic congestion areas. This is also beneficial if you have allergy and asthma sufferers in the house. When you hire someone for regular AC maintenance, they can provide air filter upgrades and replacements for you.

2.  Thermostat and Cooling Switch Issues

Over time, thermostats may need to be re-calibrated for proper operation. Basic malfunctions can also occur. And sometimes, operator error can be to blame, whereby you may have inadvertently turned off the cooling switch. If this happens frequently, you may consider upgrading to a smart thermostat.

3.  Faulty Capacitors

The heart of your AC is the compressor, and it sometimes needs a jolt of power to start up initially and then to keep running. The capacitor is what provides that jolt and much like a rechargeable battery, it does store energy. Heat and power surges are two risks posed to the capacitor, especially in summer when lightning strikes are more common and temps are running very high.

4.  Blocked Registers

Blocked, clogged registers and vents keep cold air from blowing throughout the house. Your ductwork may have tears and holes in it that can lead to cold air leakages, which will impact distribution and consistency.

5.  Dirty Condensing Coils

The large condensing coils present on the outdoor unit can cause issues for your AC. Dirty coils and bent fins detract from the ability of the unit to blow cold air. Your HVAC technician can flush out and clean these coils periodically so they work properly.

6.  Power Issues

It may sound like a no-brainer, but have you checked that you plugged the cord in correctly? Is there damage to the cable or plug head? If those are both fine, the electrical panel itself could be to blame, thanks to a tripped breaker or blown fuse.
