Your Air Conditioner Not Cooling? Here's What You Can Do!

Dealing with a malfunctioning air conditioner during the peak of summer is not just inconvenient—it can turn your cozy retreat into a sweltering hotbox. Before you start worrying, it’s helpful to know that this is a common problem and often fixable with a few simple checks. Here’s a homeowner’s guide to diagnosing common AC issues and understanding when it's time to call the experts at Dual Temp HVAC Home Services.

 

1. Check Your Refrigerant Levels

Your AC needs refrigerant to cool your home efficiently. If it's running low, possibly due to leaks developing or not being charged correctly, you won't get that refreshing cold air. Look for signs like ice on the refrigerant lines or a oily patch on the refrigerant lines and both indoor and outdoor coils. Should you spot these telling symptoms. These are tasks best repaired by a professional from Dual Temp HVAC Home Services to ensure safe and correct repairs.

 

2. Inspect the Condenser Coils

The condenser coils, found in the outdoor unit, play a crucial role in dissipating heat. If they're dirty or damaged, your system's cooling capacity drops. While cleaning these coils can be a DIY task, any damage might require professional service to fix or replace the coils. Again you can spot leaks by looking for oily spots. When the refrigerant leaks out, it carries with it, its lubricating oil. If its an old slow leak, it will be a small spot with dirt built up on the oil.

 

3. Evaluate the Compressor

The compressor is essential, circulating refrigerant and powering the cooling cycle. If your home isn't cooling well, the compressor could be to blame. Due to its complex nature, diagnosing and repairing compressor issues should be left to professionals. The staging on/off, and safety lockouts are too complex to cover in this article.

 

4. Replace Clogged Air Filters

A common and easily fixable issue is a clogged air filter. Restricted airflow can significantly reduce your system’s efficiency. It can even lead to a frosted indoor evaporator coil (see below) Check and replace your air filters every few months to keep things running smoothly.

 

5. Troubleshoot Electrical Problems

Issues like tripped circuit breakers or blown fuses can stop your AC from working entirely. Reset the breakers and check for any visible issues, but if problems repeat, it’s time to call in a professional to avoid further damage. Reset the breaker only once. If it trips again its time for a pro. Wiring could be shorting, circuit boards could be blown, this isn’t an area to troubleshoot without an extensive background in troubleshooting electrical circuits.

 

6. Fix Thermostat Issues

Sometimes the problem is as simple as a malfunctioning thermostat. Try replacing the batteries, resetting it, or even consider upgrading to a more reliable smart thermostat. A pro can tell you if your problem is limited to your thermostat or is elsewhere in the system.

 

7. Seal Leaky Ductwork

Duct leaks can lead to significant cooling loss, making your system work harder and increasing energy costs. Sealing these leaks can enhance your AC’s efficiency and effectiveness. Check both the return ducts (air getting sucked from the room), and the supply ducts (cold air getting delivered into the space).

 

8. Thaw Frozen Evaporator Coils

If you notice ice on the indoor unit, it’s likely your evaporator coils have frozen—this impedes your unit's ability to absorb heat. Turn off the unit to let the coils thaw. This could take several hours. Call Dual Temp Home Services if the issue doesn’t resolve itself.

 

9. Clear Blocked Condensate Drain Lines

A blocked condensate drain can trigger a shutdown of your AC system. Cleaning out the blockage might get things running again, but if you’re unsure of how to safely do this, our team can help.

 

10. Consider the Age and Size of Your AC

An outdated or undersized AC may struggle to keep up with the cooling demands of your home. If your unit is old or doesn’t fit the size of your home, it might be time for an upgrade.

 

11. Ensure Proper Installation

Improper installation can lead to numerous issues, including inefficient cooling, and a significantly shorter equipment lifespan. It’s crucial to have your system installed by licensed and trained professionals like those at Dual Temp to assure optimal performance.
