HVAC Services Brainerd MN | Call Kruchten's Heating & Air Conditioning

Short cycling is a common issue here, often caused by a dirty air filter restricting airflow, an oversized furnace for your home, or a faulty flame sensor. This constant stopping and starting puts extra strain on your system, increases energy bills, and fails to heat your home evenly. Our technicians can quickly diagnose the root cause and perform the necessary repair or adjustment to restore proper, efficient operation.

While turning off the system to let the ice melt is a safe first step, the ice itself is a symptom of a problem, not the cause. In our climate, ice buildup typically indicates low refrigerant levels, a dirty evaporator coil, or insufficient airflow from a clogged filter or blocked vents. Letting it run can cause serious damage. It's best to call us. We'll thaw the unit safely, perform a thorough inspection to find the underlying issue, and make the repair to prevent it from happening again.

The single most effective thing you can do is change your furnace and AC air filters regularly—at least every 1-3 months, especially during peak heating and cooling seasons. A clean filter ensures proper airflow, which is critical for preventing both short cycling and ice buildup. Additionally, keep the area around your outdoor condenser unit clear of leaves, grass, and snow. For comprehensive protection, we recommend our seasonal maintenance plans, where our technicians perform detailed inspections and cleanings to catch small issues before they become big, costly repairs.
