HVAC Services Norfolk NE | Call Heartland Heating & Air Conditioning

An evaporator coil freeze-up is often caused by restricted airflow or low refrigerant levels, common issues in our area due to dusty conditions or aging systems. Restricted airflow from a dirty filter or blocked vents forces the coil to get too cold and freeze. Low refrigerant can have the same effect. We recommend checking your filter monthly and scheduling an annual maintenance check with us to prevent this problem and keep your system running efficiently.

Leaky air ducts force your HVAC system to work much harder to heat or cool your Norfolk home, as conditioned air escapes into attics, crawl spaces, or walls before reaching your living areas. This inefficiency can lead to noticeably higher energy bills, uneven room temperatures, and excess strain on your equipment. Our technicians perform detailed duct inspections and sealing to ensure the air you pay for is delivered where you need it, improving comfort and reducing monthly costs.

Key signs of a refrigerant leak include reduced cooling power, ice forming on the copper refrigerant lines or evaporator coil, a hissing or bubbling sound from the unit, and a noticeable increase in your electricity bill. Since refrigerant is essential for the heat transfer process, a leak diminishes your system's ability to cool your home effectively. If you notice any of these signs, it's important to call us for a professional diagnosis and repair to prevent further damage to the compressor.
