Warm air, short cycling, strange noises, or an AC that will not start are signs your cooling system needs attention. Dunco has repaired air conditioners in Lawrence since 1988. Our licensed technicians provide same or next-day service and explain upfront pricing before repair work begins.

Air Conditioning Repair Services We Provide in Lawrence

AC problems can start with electrical components, airflow, controls, or the cooling system itself. Our technicians diagnose the cause before replacing parts.

Central AC Repair

A central AC that runs but does not cool, cycles repeatedly, or produces weak airflow needs professional attention. The problem can start at the thermostat, blower, outdoor unit, or another system component. Our air conditioning services start with diagnosing the source of the problem before making repairs.

Ductless Mini Split Repair

Ductless systems have their own controls, indoor air handlers, and refrigeration components. A unit that stops cooling, leaks water, or displays an error needs diagnosis based on the affected zone and equipment.

Thermostat and Airflow Issues

A faulty thermostat prevents normal cooling cycles, while dirty filters, blower trouble, or other restrictions can reduce airflow. Between repairs, AC maintenance and tune-ups clear routine buildup and give worn components a chance to be found before summer puts the system under heavier use.

Signs Your AC Needs Repair

AC Blowing Warm Air

Warm air means the system is running without producing or delivering enough cooling. Refrigeration problems, dirty coils, airflow restrictions, or electrical faults can all produce this symptom.

AC Short Cycling

Repeated starts and stops mean the system is not completing a normal cooling cycle. Continuing to run it this way adds wear without solving the underlying problem.

Ice on Refrigerant Lines

Ice on the refrigerant lines is not normal. Turn the cooling system off and let the ice thaw rather than continuing to operate it. Restricted airflow or a refrigeration problem needs diagnosis.

Water Around the AC

Water around indoor equipment can come from a blocked condensate drain or melting ice. Address the source before leaking water damages nearby flooring or materials.

Loud or New Noises

Grinding, banging, squealing, or repeated clicking can signal mechanical or electrical trouble. New sounds that continue during operation are a reason to have the system inspected.

Breaker Keeps Tripping

Do not repeatedly reset a breaker that trips when the AC starts. Repeated trips can indicate an electrical or equipment problem that needs professional diagnosis.

What Happens During an AC Diagnostic Visit

Our technicians start with the symptoms you noticed, then inspect and test the parts of the system connected to the problem. Once the cause is identified, we explain what failed and the price of the repair before any work begins.

If the problem keeps returning or the AC has stopped cooling, schedule AC repair so the cause can be identified before additional components are affected. After the repair, we test system operation again.

Repair or Replace? How to Decide

A repairable problem does not automatically mean you need a new air conditioner. Age, repair history, equipment condition, efficiency, and the size of the current repair all belong in the decision.

Frequent repairs, higher operating costs, limited parts availability, and the risk of another summer breakdown can make continued repairs harder to justify.

If breakdowns are becoming more frequent or the system needs a major repair, AC replacement and installation lets you replace aging equipment before the next failure leaves your home without cooling.

Financing options let you spread the cost of AC replacement over time instead of paying the full amount upfront.
