All Hours Heating & Air Conditioning - Mayville's Experienced HVAC Repair

Ice buildup on your outdoor unit in our Mayville climate is often a symptom of restricted airflow (like a dirty filter), low refrigerant, or a failing component. While it can reduce cooling and increase energy bills, it's typically not an immediate equipment-killer if addressed promptly. However, running the system with ice can cause further damage. We recommend turning the system off and calling us for a diagnosis to prevent a minor issue from becoming a major, costly repair.

We use electronic leak detectors and ultraviolet dye to precisely locate even small leaks in your AC's refrigerant lines and coils. Once found, our EPA-certified technicians repair the leak according to manufacturer specifications, then pull a deep vacuum on the system to remove moisture and air. Finally, we recharge the system with the exact amount of refrigerant specified for your unit. This thorough process ensures your Mayville home cools efficiently and helps prevent the leak from recurring.

Key signs your AC may have a refrigerant leak include reduced cooling power despite the system running constantly, ice on the indoor or outdoor coils, a noticeable hissing or bubbling sound near the unit, and higher-than-normal energy bills. If you notice warm air from vents or the system short-cycling (turning on and off frequently), it's time to call us. Early detection and repair of a leak protect your compressor from severe damage and restore your system's efficiency.
