Your HVAC system works hard to keep your home comfortable year-round, but when something goes wrong, it can be frustrating—and expensive. Before you pick up the phone to call a technician, there are several troubleshooting steps you can take to identify and even fix minor HVAC issues yourself. In this article, the Habberjam at Home team walks you through common heating and cooling problems Edmonton homeowners face and how to solve them.
Problem #1: Furnace Won’t Turn On
Why This Could Be Happening:
- Thermostat settings are incorrect
- Tripped breaker or blown fuse
- Clogged air filter
- Pilot light or ignition issues
Troubleshooting Steps:
✔️ Check the Thermostat – Ensure it’s set to “heat” and the temperature is higher than the current room temperature. If using a programmable thermostat, double-check the schedule settings.
✔️ Inspect the Power Source – Reset any tripped breakers or replace a blown fuse.
✔️ Replace the Air Filter – A clogged filter can block airflow and cause your furnace to shut down.
✔️ Check the Pilot Light or Ignition – If you have an older furnace with a pilot light, ensure it’s lit. For newer models, look for a flashing error code and consult the manual.
What happens if your furnace still won’t turn on? Then it’s time to call in a professional. Learn about our furnace repair services for fast and reliable help.
Problem #2: Air Conditioner Blowing Warm Air
Potential Causes:
- Dirty air filter
- Thermostat settings incorrect
- Refrigerant leak
- Blocked or dirty condenser coils
How To Fix It:
✔️ Check the Thermostat – Set it to “cool” and ensure the fan is on “auto” rather than “on” (which runs the fan continuously without cooling).
✔️ Clean or Replace the Air Filter – A dirty filter restricts airflow and can cause your AC to overheat.
✔️ Inspect the Outdoor Unit – Make sure the condenser unit isn’t blocked by debris like leaves or dirt.
✔️ Look for Ice Buildup – If you see ice on the refrigerant lines, turn off the system and let it thaw before restarting.
Is your AC is still blowing warm air? If so, you may have a refrigerant issue. Contact Habberjam at Home for professional AC repair.
Problem #3: HVAC System Making Strange Noises
What Could Be Causing It?
- Loose or broken components
- Clogged air filter
- Failing blower motor
- Refrigerant issues
Here’s How To Fix It:
✔️ Identify the Sound:
- Banging/Clanking – Loose or broken part
- Whistling – Airflow restriction (check the filter)
- Clicking – Electrical issues or failing thermostat
- Hissing – Possible refrigerant leak
✔️ Inspect the Air Filter – A dirty filter can cause whistling or rattling sounds.
✔️ Tighten Loose Components – If safe to do so, tighten any visible screws on vents or ducts.
It’s important to address unusual HVAC noises; they could be an indicator of an issue that shouldn’t be ignored. Learn more about our HVAC maintenance services to prevent costly breakdowns.
Problem #4: Weak Airflow from Vents
Why Is This Happening?
- Clogged air filter
- Blocked or leaky ductwork
- Blower fan issues
Ways To Fix It:
✔️ Replace the Air Filter – If it’s clogged, airflow will be restricted.
✔️ Check Vent Blockages – Make sure furniture or curtains aren’t blocking the vents.
✔️ Inspect Ductwork – If possible, check for disconnected or damaged ducts.
If your vents aren’t delivering proper airflow, it might be a bigger issue. Contact us for a professional HVAC inspection.
