Runge Heating & A/C | Certified HVAC Services in Alexandria, MN

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills as the system struggles to cool. If you notice any of these, it's time to call Runge for a professional diagnosis. We can pinpoint the leak, repair it, and recharge your system with the correct refrigerant to restore efficient cooling.

We often advise Alexandria homeowners with aging equipment to consider proactive replacement. Waiting for a failure in the middle of a Minnesota winter can be uncomfortable and lead to emergency service calls. Modern furnaces are significantly more energy-efficient, which can lead to substantial savings on your heating bills. We can provide a free, no-pressure assessment to compare the repair costs of your current system with the benefits and potential savings of a new, reliable unit.

It depends on the leak's location and the system's age. Many leaks, especially in copper lines or at service valves, can be successfully repaired. However, if the leak is in the evaporator coil of an older unit, replacement of the coil or the entire system might be more cost-effective, especially with newer, more efficient models. Our technicians will give you a straightforward, honest evaluation of your options for repair versus replacement, focusing on your long-term comfort and investment.
