CALL NOW 530.899.9999

Ever noticed your furnace acting a bit out of rhythm, constantly starting and stopping like it’s unsure of the beat? That’s what we call short cycling – a quirk in the HVAC system’s performance. If your furnace seems to be more on-again-off-again or runs in short bursts, lasting less than three to five minutes, you might be dealing with short cycling.

However, this irregular dance brings more than just a quirky routine; it introduces some unwanted party crashers:

Your home becomes a chilly hangout spot. Your gas bill takes an unexpected leap.

Your furnace starts gearing up for an early retirement, facing undue wear and tear and potential mechanical breakdowns in the future.

Now, let’s dive into the mechanics of your furnace and explore the reasons behind this rhythmic hiccup.


Thermostat Tinkering

Incorrect Configuration:

 Think of checking thermostat settings as tuning into your favorite radio station. Ensure it’s singing in harmony with your comfort preferences and the current season. Verify the programmed temperature, mode (heat or cool), and fan settings for accuracy.

Malfunctioning Thermostats:

 Thermostats can lose their touch over time. If your old thermostat is out of tune, it’s time to bring in a replacement to ensure accurate communication of temperature requirements to the furnace.


Dirty Air Filter


Airflow Restriction:

 Clogged air filters act like a barricade on the dance floor – they hinder the smooth flow of air through the HVAC system. This disruption leads to overheating as your furnace struggles to circulate warm air efficiently.

Regular Maintenance:

Establish a routine for your air filter check-ups. Check those filters monthly and replace them when they’re feeling a bit dirty – it’s like giving your furnace a spa day.


Blocked Vents or Registers


Furniture or Debris Obstruction:

 Ensure your vents and registers aren’t hiding behind furniture or curtains. Unrestricted airflow is the key to proper furnace functioning.

Balancing Airflow:

 Adjust furniture placements to create an even flow of air throughout your home. Properly balanced airflow is a secret ingredient for a more efficient HVAC system.


Furnace Short Cycling


Incorrect Furnace Sizing


Rapid Heating:

 An oversized furnace can heat your home too quickly, causing premature shutdowns. Consult HVAC professionals to assess proper furnace sizing for your home.

Energy Efficiency:

 Right-sizing your furnace improves energy efficiency and reduces operational costs.


Flame Sensor


Signal Misinterpretation:

 The flame sensor detects the presence of a flame. A malfunction may cause inaccurate signals, leading to shutdowns.

Regular Cleaning or Replacement:

 Clean the flame sensor with a soft cloth to remove debris. If cleaning doesn’t work, consider replacing the flame sensor for accurate flame detection.
