Fixing AC leaks can make a big difference in your cooling costs and overall system efficiency. Ducts can lose up to 30 percent of airflow through leaks, so it's essential to find and fix them.

To find leaks, try the "smoke trick" - light a stick of incense and hold it where the unit and the window frame meet for window units, or near duct connections for central AC. If the smoke blows around, you've got a leak.

For ductwork, use foil tape to seal small gaps and duct mastic for larger ones. For window AC units, stuff foam between the device and the window frame, taping as needed.

Weak Flow can be a real problem, especially during the hot summer months. It's when your air conditioner is running but the air barely moves.

Dust, debris, or even mold can clog your ducts, blocking airflow entirely. Make sure furniture or rugs aren't covering your vents, as this can also restrict airflow.

Dirty evaporator coils can also cause weak airflow. If the coils are caked in grime, it's like trying to breathe through a dirty filter.

Leaky ductwork is another common culprit. Small holes or gaps in ducts let cool air escape before it reaches your vents, leaving you feeling hot and miserable.

A failing blower motor can also cause weak airflow. If the blower fan isn't running at full speed, it won't push air through the system efficiently.

Here are some possible causes of weak airflow:

Start by vacuuming your vents and replacing the filter. If airflow is still weak, it’s time for a professional duct inspection or system checkup.

Insulate to keep your aircon running smoothly. Ducts in hot attics or crawl spaces should be wrapped with spray foam, batt insulation, or rigid-foam insulation to keep the air within them cool.

Seal batt and rigid insulation with foil tape, not duct tape. This will ensure a tight seal and prevent air leaks.

Regularly check the insulation around your HVAC copper piping. Insulation maintains thermal efficiency within your HVAC system, so it's essential to keep an eye on it.

Visually inspect the condition and completeness of the insulation around the evaporator and suction lines. Look for signs of damage from harsh weather, pests, rodents, or insects.

If you find any exposed insulated AC pipework sections, contact an HVAC specialist for assistance.

Maintenance scheduling is crucial to keep your aircon running efficiently and effectively. It's essential to schedule annual AC maintenance before the cooling season starts.

You should schedule a yearly cleaning schedule that goes beyond just cleaning the filters. This should include tasks such as cleaning and inspecting coils, adjusting and replacing fan belts, and lubricating motors and bearings.

A professional tune-up is like an oil change for your car. It's a regular seasonal inspection that prevents breakdowns and helps your equipment last about 40% longer.

You can schedule an AC tune-up with a licensed HVAC professional. This service includes tasks such as conducting a multi-port test, troubleshooting common maintenance issues, and lubricating mechanical parts.
