FAQs

How much does AC repair cost for a typical home unit?

AC repair cost for a typical home unit is confirmed after a technician diagnostic, and ABC provides upfront, written pricing with a $29 Cooling System Diagnostic that’s credited toward the repair. Costs vary by which component failed, the time needed to access and fix it, and whether refrigerant or electrical work is involved. If you need maintenance rather than a repair, our Ultimate AC Tune-Up is $49. Our NATE-certified techs service all major brands and focus on testing before replacing parts so you only pay for what solves the issue. We regularly help homeowners throughout the area, including Elgin.

"I had an excellent experience with Brandon from ABC. He quickly diagnosed & fixed the AC drainage block issue... Highly recommended their service for HVAC needs!" — Rekha T.

How can I fix my air conditioner myself safely and effectively?

You can safely fix many minor air conditioner issues by checking settings, airflow, and power before calling a professional. The most common quick wins are correcting thermostat settings and replacing a clogged air filter that’s choking airflow. If cooling still struggles, simple outdoor cleaning and a blocked drain check may restore performance without tools. Our team handles these same homeowner steps around Glenview all summer, and they solve many no‑cool calls. If you smell burning, see repeated breaker trips, heavy water leaks, or ice buildup that returns after thawing, stop DIY and schedule repair; a breaker that trips again right away often points to a failing motor or compressor.

Try these homeowner‑safe steps:

Set thermostat to Cool/Auto, replace batteries, and lower the setpoint a few degrees.
Replace a dirty air filter; confirm all supply and return vents are open and unblocked.
Check the furnace/air‑handler switch and breaker; reset a tripped breaker only once.
Shut power off, clear leaves from the outdoor unit, and gently hose the coil fins from the outside.
Clear a clogged condensate drain with a wet/dry vac at the drain line and empty the pan.
If the indoor coil is iced, turn cooling Off and fan On to thaw for a few hours before retrying.

Always shut off power at the disconnect before touching the outdoor unit.

Is it worth replacing an AC compressor or buying a new unit?

Replacing an AC compressor is worth it only when the system is newer, under warranty, and the rest of the unit is in good shape; otherwise, a full AC replacement is usually the smarter investment. Most homeowners face this choice when an older system’s compressor fails, because other aging parts can make a single major repair short‑lived. If the failure involved a burn‑out, debris and acids can spread through the lines, so swapping just the compressor can be risky without deeper cleanup. Our team regularly evaluates these scenarios across the Des Plaines area. A NATE‑certified technician can test capacity, check refrigerant condition, and confirm warranty coverage before you decide.

Consider replacement if you notice:

Unit is 10–15+ years with other issues
No active parts warranty on the compressor
Repeated breakdowns or poor cooling even after repairs
Significant coil corrosion or airflow problems

Have a licensed HVAC pro perform a full diagnostic and warranty check before committing either way.

"Not only did he fix my AC in a short amount of time, he explained everything." — Temi O.

Why is my AC running but not cooling properly?

An AC that runs but isn’t cooling properly is typically due to restricted airflow, low refrigerant, thermostat misreads, or a failing electrical component. Most often, airflow is the culprit—clogged filters, dirty coils, or leaky ducts limit heat transfer so the air never gets truly cold. If the outdoor fan spins but the air stays warm, a weak capacitor or sticking contactor can keep the compressor from doing its job. Our NATE-certified technicians handle these problems across the Chicagoland area, and emergency service is available 24/7 when the system is at risk.

Schedule repair now if you notice:

Blowing warm air from the vents
Outside unit freezing up
Drain pan overflowing or visible water leaks
Short-cycling, odd noises, or persistent odors

Turn the system off if you see ice or water and arrange a professional inspection to prevent compressor damage.

How much does AC compressor replacement cost for homeowners?

AC compressor replacement pricing depends on your system and is confirmed after an on-site diagnosis. A technician will evaluate compressor condition, refrigerant type, system size, accessibility, and any warranty coverage. We service all brands and can install Carrier equipment when replacement is the best option. Same-day and 24/7 service are available in Chicago and nearby suburbs.

Quick checks:

Verify if your compressor is still under parts warranty.
If the system is older or has repeat failures, consider full AC replacement.

What should I do if my AC is blowing warm air intermittently?

If your AC blows warm air on and off, start with quick checks. Set the thermostat to Cool and a lower temperature. Replace the air filter. Make sure the outdoor breaker and disconnect are on, and clear debris from the condenser. If it still turns warm, it likely needs professional diagnostics for issues like low refrigerant, a bad capacitor, or thermostat faults. ABC offers same-day, 24/7 AC repair in Chicago and nearby, with NATE-certified techs and upfront pricing.

Thermostat: Cool mode, fan Auto
Filter: replace if dirty
Power: check breaker/disconnect
Outdoor unit: clear coils/debris
