An air conditioner not turning on with the thermostat set to Cool usually points to a power issue, a thermostat problem, a safety shutdown, or a failed start component. The most common cause we find is lost power from a tripped breaker or dead thermostat batteries. Other times, a safety device stops the system to prevent damage, like when a clogged drain triggers a float switch, or a capacitor can’t start the compressor or fan. A dirty filter can also strain the system enough to keep it from starting reliably. Our team services homes throughout the Indianapolis area, including work right here in Castleton.
Try these quick checks before calling:
- Confirm thermostat batteries, mode (Cool), and a set temp below room temp.
- Check the HVAC breaker and the furnace/air-handler switch.
- Look for water in the drain pan or a tripped float switch; clear the drain if clogged.
- Replace a dirty filter; if the outdoor unit is silent, a capacitor or contactor may have failed.
If a breaker keeps tripping, you see water, or you smell burning, leave the unit off and schedule professional service.

The average furnace repair cost for homeowners isn’t a single set price at Summers; we provide upfront, itemized pricing after a diagnostic so you know the total before work starts. Most variation comes from which component failed and the labor needed to access, test, and verify a safe fix. Every repair is backed by reliable warranties, and this month you can receive a free service call with any paid repair. Our technicians work throughout the Indianapolis area daily, bringing local know-how and fully stocked trucks to speed up common furnace fixes. For urgent situations, we offer around-the-clock emergency HVAC repairs.
Cost typically depends on:
- The specific component and whether parts are readily available
- System type and age, which affect complexity and labor time
- Additional issues uncovered during testing and safety checks
- Whether maintenance has been kept up or deferred
Schedule a diagnostic to confirm the problem and get a firm quote before you decide.

Same-day HVAC repair pricing is confirmed after an on-site diagnostic because the final cost depends on the exact failure and parts required. Most variation comes from whether the fix is a quick adjustment or a component replacement. With Summers Plumbing Heating & Cooling, you approve upfront pricing before work starts, and we offer a free service call with any paid repair. Our team can respond the same day with fully stocked trucks, and we serve homes across the Indianapolis area, including Lawrence.
Cost is mainly driven by:
- Diagnostic findings: minor electrical or thermostat issues versus compressor, blower, or control board failures.
- Parts and availability: OEM versus universal parts and whether the truck has it today.
- System type and age: furnace, AC, heat pump, or mini split; older systems can require more labor.
- Access and refrigerant needs: tight attic or crawlspace access and any refrigerant work add time and materials.
Schedule a diagnostic so a licensed technician can confirm the issue and give you a firm, upfront price before any work begins.
