Ductless systems are common in room additions, sunrooms, converted garages, and homes without central ductwork throughout New Lenox. We repair wall-mounted and ceiling-mounted units, single-zone and multi-zone setups, for both residential and light commercial properties.

Ice on the coil is often the result of poor airflow or a refrigerant problem, but the unit has to thaw before we can get an accurate reading. Once the ice is gone, we test the system and check what caused it to freeze in the first place.

We do not assume an error code means the control board needs to be replaced. The code only tells us where the system detected a problem. Sometimes the repair is a connection or sensor issue, while other calls do end with a failed board

Water running down the wall below the indoor unit is one of the clearest signs of a blocked drain. Algae can collect inside the line until the water has nowhere else to go. Clearing the blockage usually solves the leak, but we also look for damage around the pan and wall.

The compressor drives the whole heating and cooling cycle from the outdoor unit. One that's short cycling, overheating, or won't start cuts capacity on both sides of the system. We run electrical and pressure tests, then lay out the cost of repairing the compressor against replacing the outdoor unit so you can decide with real numbers.

Low refrigerant is the most common reason a mini-split loses cooling or heating capacity. We find the leak, seal it, and recharge the system to the level set by the manufacturer. Refrigerant handling is regulated by the EPA, and our technicians are certified to work with it.

A technician checks the indoor and outdoor units, tests the electrical components, and reads any active error codes to pin down the cause.

If there's more than one way to fix it, we walk you through the cost and outcome of each.

Trucks carry parts for the repairs we see most, including fan motors, control boards, and refrigerant service.

Heating and cooling modes are both checked to confirm the repair holds.

If a repaired part fails within the warranty period, we return and fix it at no charge.

Your mini split system requires a service, when it is no longer energy efficient. If you notice that your power bills are higher than normal, even though nothing has changed, that's a sign that your system is probably working harder than it needs to.

A musty smell coming from the mini-split usually means there is moisture or buildup somewhere inside the indoor unit. It should still be checked and cleaned, but a burning smell needs attention right away. Shut the system off and do not run it again until someone has looked at it.

Dripping water isn't normal condensation. It's usually a blocked drain line or ice on the coil from a refrigerant leak, and each has a different fix.

Rattling or buzzing points to a loose part or a fan motor on its way out. Grinding usually means the blower wheel has worn down enough to contact its housing.

This points to low refrigerant, a failing compressor, or a clogged filter. Running it this way for too long adds wear to the compressor and raises the eventual repair cost.

Dave McLaren started the company in 1971. His son Gary trained under him and runs it today, carrying two generations of work in this area.
