Answers to Common Questions
View All FAQsWhy Is My AC Running But Not Cooling Properly?
An air conditioner that runs but isn’t cooling usually has an airflow blockage, a refrigerant leak, or a control or compressor issue that prevents heat removal. The most common cause is restricted airflow from a dirty filter or a clogged indoor or outdoor coil. Other frequent problems include low refrigerant, electrical faults, and outdoor fan failures. We handle these issues for homeowners throughout the Plainfield area and use quick, accurate diagnostics to find the root cause. Our certified technicians arrive in fully stocked trucks, so many AC repairs finish in a single visit. If performance keeps dropping after resets and cleanings, repair is typically the next step; when a major component fails or leaks recur, replacement may be the smarter long-term choice.
Before you call, check these quick items:
- Replace a dirty filter and open all supply/return vents.
- Set the thermostat to Cool, Fan Auto, and a setpoint 3–5°F below room temp.
- Clear debris from the outdoor unit; with power off, gently rinse the coil from the outside.
- Look for ice on refrigerant lines or hear hissing/bubbling, then leave the system off.
If coils are iced or the outdoor unit isn’t blowing warm exhaust air, turn the system off to prevent damage and schedule service.

AC repair gets expensive when a major part fails, refrigerant work is needed, or the job requires long, difficult labor. The most common cost driver is a failed compressor or leaking coil, because these parts are pricey and time‑intensive to replace.
Our technicians also see costs rise when systems are older, poorly maintained, or hard to access; a small issue that’s ignored can grow into multiple component failures. We handle these same patterns across many Franklin homes during peak summer.
When repair bills climb, these specifics are usually why:
- Compressor replacement or coil changeout (evaporator or condenser)
- Refrigerant type and amount, plus leak find-and-fix time
- Blower motors, control boards, or wiring damage tied to the root failure
- Attic, crawl, or roof access that adds hours and specialized setup
Johnson provides honest, upfront flat‑rate pricing with no surprise fees. Ask us to compare repair versus replacement if failures repeat or the unit is near end of life. <br/> Updated: 2026-06-05 <br/> Need help in Franklin, IN? Call 317-830-5862 or book online.

Yes—turn the AC off at the thermostat if it’s blowing warm air to prevent further strain or icing. The most common root cause is an airflow or refrigerant issue that lets the system run without cooling and can freeze the indoor coil. When we find a unit blowing warm but running nonstop, it’s often ice from low airflow rather than a refrigerant leak. Our local team services the Franklin area and can quickly diagnose issues like frozen coils, wiring faults, or thermostat problems, and most repairs are finished in one visit with fully stocked trucks.
Try these simple checks before restarting:
- Set thermostat to Cool and a few degrees below room temperature.
- Confirm the furnace/air handler switch and breaker are on.
- Replace a dirty air filter.
- If you see ice on lines or coil, leave the system off and set the fan to On until thawed.
If warm air continues after these steps, schedule a professional AC diagnostic before running the system again.

Replacing an AC compressor is worth it when the system is fairly new, still under parts warranty, and the rest of the equipment is sound; if the unit is older or has other issues, replacing the whole system is usually the better long-term value. The most common reason to choose a new system is that a failed compressor often signals broader wear, and the repair cost approaches a big share of full replacement. A tech’s take: when a compressor burns out, contaminants can spread through the lines, so a swap can fix today’s problem but leave tomorrow’s.
Look toward full replacement if you notice:
- Out-of-warranty compressor with repeated breakdowns
- Corroded or leaking coils or other major parts aging out
- High energy use or uneven cooling that points to overall inefficiency
- Older refrigerant type or mismatched components after repair
We routinely help homeowners in the Boggstown area compare a compressor change versus a matched, efficient system so the numbers are clear. Ask a licensed HVAC technician to run a full system diagnostic and provide written compressor vs. replacement quotes so you can compare total cost, warranty, and efficiency.

AC compressor replacement cost is confirmed only after an on-site diagnostic and written quote because pricing varies by system and parts. The biggest drivers are compressor size and type, refrigerant requirements, and whether any manufacturer part warranty still applies; labor can also change with access and the need to clean and protect the refrigerant circuit. We handle these replacements for homeowners throughout the Fountaintown area with clear, flat-rate pricing. When a compressor fails in a dirty system, we also flush lines and replace the filter-drier to protect the new part. Ask about our $50 off AC repair coupon (excludes diagnostic; expires 2026-05-06).
Key factors that change the price include:
- Compressor size/brand and current availability
- Refrigerant type and required recharge amount
- Part warranty coverage vs. out-of-warranty replacement
- Labor scope: brazing, line-set flush, filter-drier/contactors/capacitor, and unit accessibility
If your system is aging or has multiple major issues, replacing the whole unit may be more cost-effective than a compressor-only repair.

To fix an air conditioner yourself safely and effectively, start with simple, no‑tools checks and avoid any electrical or refrigerant work. The most common DIY wins are correcting thermostat settings and restoring airflow blocked by a dirty filter or a clogged drain. If the unit still struggles, don’t keep forcing it to run; that can turn a small issue into a major repair. A seasoned tech’s note: half of the “no‑cool” calls we see trace back to a thermostat setting or a tripped safety float from a backed‑up condensate drain. Our team regularly handles anything beyond basics for homeowners throughout the Fishers area.
Try these safe steps first:
- Set thermostat to Cool, 5° lower; replace batteries if used.
- Check the breaker and the furnace/air‑handler power switch.
- Replace a dirty air filter to restore airflow.
- Clear leaves from the outdoor unit; gently rinse the coil with power off.
- Vacuum a clogged condensate drain line from the outside port.
- If ice is present, run Fan‑only for several hours, then restart.
If you smell burning, hear popping, or see repeated breaker trips, shut the system off and call a licensed technician.
