Spring in Winnipeg means warmer weather and the start of the cooling season. However, after months of inactivity, your HVAC system might not run as smoothly as expected. If you’re experiencing AC not cooling, strange noises, or airflow issues, don’t panic! Here’s a troubleshooting guide to help you diagnose and fix common springtime HVAC problems.

Solution
a)    Clean or replace the air filter.
b)    Ensure the thermostat is set to "cool" mode.
c)     Inspect outdoor condenser coils for dirt and debris—clean if necessary.
d)    If the issue persists, you may need an HVAC technician to inspect for any underlying
problems.

Problem 2
The system is on, but there’s little or no airflow.
Why this might be happening:
a)    Dirty or blocked air ducts
b)   Blocked or closed vents.
c)    A blower fan clogged with dust
Solution
a)    Open all vents and ensure they’re not blocked.
b)   Take a look at the ducts for any leaks or blockages.
c)    Turn off the unit and check if any parts are loose
d)   Clear away any debris around the outdoor condenser
e)    If airflow is still weak, it’s time to call in a pro for an HVAC inspection.

Problem 3
AC Turning On and Off a Lot
Your AC keeps turning on and off way too often.
Weird Noises from the AC
Your AC is making some odd noises, like rattling, buzzing, or banging.
Why this might be happening:
a)    Loose or broken parts: A part inside the unit may have come loose or broken.
b)    Debris in the outdoor unit: Leaves, twigs, or dirt can get stuck in the outdoor condenser.
c)    Worn-out motor or fan blades: Over time, the motor or fan blades can wear down, causing noise.
Solution:
a)       Turn off the unit and check for any loose parts.
b)      Clear any debris around the outdoor condenser.
c)       If the noise persists, contact an HVAC professional to inspect the unit.
Problem 4
Your AC keeps turning on and off constantly.
Why this might be happening:
a)    Dirty or faulty thermostat
b)   Clogged air filter restricting airflow
c)    Oversized or undersized AC unit
d)   Electrical Issues
Solution:
a)     Replace or clean the air filter.
b)     Check that the thermostat is functioning properly and not near heat sources.
c)     If the problem persists, contact an HVAC professional to adjust or replace your system
Problem 5
You notice water pooling around your indoor AC unit.
Why this might be happening:
a)    Clogged condensates drain line.

b)   Frozen evaporator coils.
c)     Low refrigerant causing the coils to freeze and leak
Solution:
a)    Unclog the drain line using a vacuum or mild bleach solution.
b)    If the evaporator coils are frozen, turn off the unit and let them thaw before restarting.
c)     Persistent leaks may indicate a refrigerant issue—contact an HVAC technician in Winnipeg for repairs.
