With Vaughan summers averaging 71°F (21°) to 75°F (24°C), sometimes reaching as high as 88°F (31°C), your air conditioner (AC) is the unsung hero for keeping your home cool. But what happens when your AC throws a wrench in those plans? Before resorting to a full-blown AC repair, there are a few common issues you can deal with yourself.
Equip yourself with the knowledge to tackle some basic AC problems and make sure your home remains a safe haven from the heat. Just remember that if you have more complex issues or are uncomfortable performing any of these steps, contact a qualified HVAC technician.
Common AC Issues and Solutions
AC Won’t Turn On
-
Check the Thermostat
Set the thermostat to “cool” mode and the desired temperature is lower than the current room temperature.
-
Inspect the Power Source
Verify the AC is plugged in and the circuit breaker hasn’t tripped. Check for a blown fuse in your fuse box (if applicable).
-
Clean the Air Filter
A clogged air filter restricts airflow and can prevent the AC from functioning properly. Replace or clean your air filter monthly (more often if you have pets).
AC Blowing Warm Air:
-
Dirty Condenser Coil
The condenser coil on the outdoor unit releases heat. A dirty coil reduces its efficiency, leading to warm air blowing indoors. Locate the condenser coil (usually outside, near the foundation) and gently remove any debris with a garden hose. Avoid using a pressure washer, which can damage the delicate fins.
-
Low Refrigerant Level
Low refrigerant can significantly impact cooling performance. While you can’t directly refill the refrigerant yourself, a low level might indicate a leak. If suspecting a leak, contact a qualified technician for repair.
-
Frozen Coil
If the evaporator coil (located inside the unit) freezes, it restricts airflow and results in warm air. This typically happens due to dirty air filters, low refrigerant levels, or restricted airflow. Turn off the AC and allow the ice to melt completely before restarting. Address the underlying cause — dirty filter or low refrigerant — before restarting the AC.
AC Not Cooling Evenly
-
Uneven Airflow
Blocked vents or closed doors can prevent cool air from reaching all areas of your home. Ensure all vents are open and unobstructed by furniture or rugs. Check if any rooms have closed doors while the AC is running.
-
Dirty Ducts
Dirt and dust buildup in your air ducts can impede airflow and reduce cooling efficiency. Consider professional duct cleaning every few years, especially if you have pets or allergies.
AC Making Unusual Noises
-
Loose Parts
Rattling or banging noises could indicate loose screws or panels within the unit. Turn off the AC and visually inspect for loose components. Tighten any loose screws you may find.
-
Fan Issues
Worn-out fan belts or bearings can cause a variety of noises, from grinding to squeaking. While a basic inspection is possible, these issues typically require professional repair or replacement.
AC Leaking Water
-
Clogged Drain Line
A clogged drain line prevents condensate (moisture) from draining properly, leading to leaks. Locate the drain line (typically near the indoor unit) and clear any debris that might be blocking it. You can also pour a small amount of warm water down the drain line to test its flow.
-
Full Drain Pan
The drain pan collects condensate before it exits through the drain line. A full pan can overflow and cause leaks. If the pan is full, empty it and investigate the cause – potentially a clogged drain line or low refrigerant levels.
Things to Remember When Troubleshooting Your AC
- Always turn off the AC and disconnect it from the power source before performing any troubleshooting steps.
- If you’re uncomfortable with any troubleshooting procedures, don’t hesitate to call a qualified HVAC technician.
When to Call a Professional
If the troubleshooting steps above don’t resolve the issue, it’s time to call a professional for AC repair. Here are some signs that professional help is needed:
- The AC unit is making loud or unusual noises.
- There are signs of a refrigerant leak (bubbling sounds, hissing, oily residue).
- The electrical system seems faulty (burning smell, sparks).
- The air conditioner is more than 10 years old and experiencing frequent problems.
Preventative AC Maintenance
Regular AC maintenance is crucial to prevent problems and ensure optimal performance. Here are some key maintenance tips:
-
Change the Air Filter
Replace your air filter monthly (more often with pets) to maintain proper airflow and efficiency.
-
Schedule Professional Maintenance
An annual professional cleaning and tune-up by a qualified technician can identify potential issues early and extend the lifespan of your AC unit.
-
Keep the Area Around the Outdoor Unit Clear
Remove any debris, leaves, or overgrown vegetation that could restrict airflow to the condenser coil.
-
Inspect Outdoor Unit Fins
Visually check the condenser coil fins for any damage. Straighten bent fins carefully with a fin comb (available at hardware stores). Avoid using sharp objects that could damage the fins.
Benefits of Regular AC Maintenance

Regular maintenance ensures your AC runs smoothly and efficiently, potentially lowering your energy bills.
-

A well-maintained AC provides consistent cooling throughout your home.
-
