Das Heating & Cooling - Andover's Licensed HVAC Services

Ice buildup on your outdoor unit, common in our Andover climate, usually signals a problem like low refrigerant, a dirty evaporator coil, or restricted airflow. It is a concern that needs prompt attention. Running the system with ice can cause serious damage to the compressor. We recommend turning the system off at the thermostat and calling us. Our technicians can diagnose the root cause—often a simple fix like cleaning or recharging refrigerant—to prevent a minor issue from becoming a major, costly repair.

Spiking heating bills are a frequent issue for Andover homeowners, especially with older systems. Before calling us, check your air filter—a clogged filter is the most common culprit, forcing your furnace to work harder. Also, ensure all vents are open and unobstructed. If those are fine, the issue could be a dirty burner, failing heat exchanger, or an aging system losing efficiency. Our comprehensive furnace tune-up specifically targets these problems, cleaning critical components and testing efficiency to restore performance and reduce your energy costs.

Proactive maintenance is key to managing costs in our variable Minnesota weather. For Andover homes, our twice-a-year service prevents the two biggest local issues: summer ice damage and winter inefficiency. In spring, we clean coils and check refrigerant to ensure your AC runs smoothly and avoids ice-related breakdowns. In fall, we clean and calibrate your furnace to ensure it operates at peak efficiency before the cold hits, directly combating high heating bills. This preventative care extends system life, improves reliability, and maximizes energy savings throughout the year.
