HVAC Repair Indianapolis IN | Call Lennox Industries

Common signs include little to no airflow from your vents, unusual grinding or squealing noises from your indoor unit, and your system running constantly without properly heating or cooling your home. This is a critical repair, as a failed fan can lead to a complete system shutdown, especially during our hot summers or cold winters. Our technicians can quickly diagnose and replace the motor or fan assembly to restore proper airflow.

In our humid Indianapolis climate, algae and mold growth inside the moist drain line is the most common cause of clogs. This can cause water to back up into your drain pan or even leak, risking damage to your furnace or floors. We recommend an annual HVAC maintenance visit, where our techs will clear the line and may apply an algaecide tablet to prevent future blockages—a simple, proactive step to avoid costly water damage.

Yes, we offer comprehensive maintenance plans designed for Indianapolis homeowners. Our biannual tune-ups include inspecting and testing the air handler motor, thoroughly cleaning and clearing the condensate drain line, and checking all system components. This proactive care helps prevent unexpected breakdowns, improves efficiency to lower your energy bills, and ensures your system is ready for both our humid summers and freezing winters.
