Alberta homes commonly experience a set of repeat HVAC issues driven by long heating seasons, dust, and temperature extremes. Recognizing early symptoms helps prevent component damage and extended system downtime, which is why system behavior is often reviewed by All Around Heating & Cooling during routine service.

1. Frequent Furnace Cycling

Frequent on off cycling often points to airflow restriction, thermostat misreading, or control issues rather than outdoor temperature alone. Restricted airflow raises internal temperatures, which can trip limits and shut the furnace down before the heating demand is satisfied. Faulty thermostat placement near drafts or heat sources can also cause rapid call and satisfy patterns.

Symptoms include short run times, uneven room temperatures, and noticeable temperature swings. Repeated cycling increases wear on ignition components and relays.

2. Airflow Blockages and Duct Obstructions

Blocked supply vents, obstructed returns, or debris in ductwork reduce the volume of air moving through the system. That affects heat delivery and increases blower motor load. Over time, airflow restriction can lead to higher operating temperatures inside the furnace and reduced comfort in distant rooms.

Signs include weak airflow at registers, some rooms staying cold, and increased system noise as the blower works harder to move air through resistance.

3. Thermostat Faults

Thermostat issues range from calibration drift to wiring faults and battery failure. When the thermostat does not read room temperature accurately, the system may run longer than necessary or shut off early. Communication issues in more advanced controls can also cause inconsistent staging or delays.

Symptoms include temperature differences between rooms, system operation that does not match the displayed setting, or intermittent system response.

4. Air Conditioner Freezing

Cooling systems can freeze when airflow is too low or when refrigerant levels are incorrect. Reduced airflow across the indoor coil allows temperatures to drop below freezing, forming ice that further blocks airflow. This can originate from clogged filters, dirty coils, or duct restrictions.

Common indicators are ice on refrigerant lines, reduced cooling, and water around the indoor unit after the ice melts. Continued operation while frozen can strain the compressor.

5. Clogged Filters and Contaminated Components

Dust, pet hair, and debris build up quickly in Alberta homes, especially during winter when windows stay closed. Clogged filters reduce airflow, increase blower motor load, and affect temperature control. Dirt can also accumulate on condensers and indoor coils, lowering heat transfer efficiency.

Symptoms include higher energy use, weaker airflow, and longer run times to reach setpoint.

When to Have Issues Checked

If you notice new noises, uneven temperatures, frequent cycling, or persistent performance changes, the system should be assessed before the issue progresses. Identifying whether the cause is airflow, control, or a mechanical component helps avoid secondary damage. An HVAC system inspection by All Around Heating & Cooling technicians can confirm the source of the problem and whether corrective action is required.

Booking Service

If a fault persists or safety concerns arise, use the request service form to arrange an inspection so the issue is addressed before it leads to extended downtime.
