Berger Heating & Air Conditioning | Trusted HVAC Repair in La Crosse, WI

A common cause is a clogged condensate drain line, especially during our humid summers. This line removes moisture your AC produces, and when it's blocked, water can back up. First, turn off your AC to prevent further water damage. While you can try clearing the line with a wet/dry vac, it's often best to call a professional like Berger Heating & Air Conditioning. We'll clear the clog, check the drain pan, and ensure your system is draining properly to protect your home.

For most homes in our area, we recommend checking your air filter every month and replacing it at least every 90 days. If you have pets, allergies, or during high-use seasons, you may need to change it every 30-60 days. A clogged filter is one of the most common issues we see; it forces your furnace or AC to work harder, reducing efficiency, increasing your energy bills, and potentially causing premature system failure. Regular filter changes are the easiest way to maintain your system.

We recommend bi-annual maintenance: once in the spring for your cooling system and once in the fall for your heating. For cooling, this includes checking refrigerant levels, cleaning coils, and clearing condensate drains to prevent summer clogs. For heating, we inspect the heat exchanger, clean burners, and check airflow. This proactive approach catches small issues—like a drain starting to clog or a dirty filter—before they become costly repairs and helps your system handle our Wisconsin seasons efficiently.
