You will learn fast homeowner fixes, when to call a 24/7 pro, and how to prevent the next breakdown. If you need immediate help, our team answers the phone around the clock and dispatches quickly so your home cools again fast.

Start Here: A 5‑Minute Triage To Try Before You Sweat Another Hour

When the air stops cooling, start with quick checks that solve many calls. These steps are safe and take only minutes.

1. Thermostat check
   • Set to Cool and Auto, not On. Lower the set point at least 3 degrees.
   • Replace batteries if the screen is dim or blank.
2. Breakers and switches
   • Confirm the indoor air handler and outdoor condenser breakers are on. Some outdoor units have a nearby disconnect switch. Set it to On.
3. Filter and vents
   • A clogged filter can cause weak airflow and even freeze coils. Replace if dirty. Open at least 80% of supply registers.
4. Condensate drain
   • Many systems shut off if the drain pan float switch trips. If your drain line is clogged, the unit may stop cooling. Do not force it. Call a pro for safe clearing.
5. Ice on the lines or coil
   • If you see frost, turn the system Off and set the fan to On for 30 to 60 minutes. Ice must melt before proper diagnosis.

If these do not restore cooling, move to a professional assessment. Time matters in Columbia summer heat, so do not let the system struggle for hours.

When To Call 24/7 Emergency Service

Certain signs mean you should call immediately. The risk to your home or equipment is high, and repair delays raise costs.

• Burning smell, smoke, or frequent breaker trips
• Warm air from vents while the outdoor fan runs constantly
• Hissing or bubbling at the refrigerant lines
• Water pooling around the indoor unit or ceiling stains
• System short cycling every few minutes

Kaminer Heating And Cooling operates a true 24/7 service line with no after‑hours fees. During oppressive heat waves, fast response protects your comfort and your system. Our technicians handle emergencies day and night, and we service all brands.

What To Expect From a Professional AC Repair Visit

A quality visit is structured, transparent, and safe for your home. Here is how our process works in the Midlands.

1. Initial consultation and safety check
   • We confirm symptoms, check thermostat settings, and verify safe power and condensate conditions.
2. System component evaluation
   • We inspect the air handler, blower, evaporator coil, outdoor condenser, fan motors, and electrical components.
3. Electrical testing
   • We test capacitors, contactors, fuses, and wiring for corrosion or failure. Tight connections prevent unexpected shutdowns.
4. Refrigerant checks
   • We measure pressures and temperatures to confirm charge. If the charge is low, we test for leaks before adding refrigerant.
5. Airflow and filter assessment
   • We verify proper filter type, clean return paths, and balanced ductwork. Clogged or undersized returns choke performance.
6. Efficiency testing and final run
   • We verify temperature split, confirm condensate drainage, and check for stable cycling at normal load.

You receive clear options with upfront pricing. We provide free estimates for replacement if repair is not cost‑effective and offer financing to keep decisions simple.

The Most Common Causes of No‑Cooling in Columbia

Our local climate and housing stock create a predictable set of issues. Knowing them helps you act fast and avoid repeat failures.

Refrigerant leaks

Low charge is often a leak, not a one‑time top‑off. Leaks may occur at Schrader valves, evaporator coils, or line sets. Symptoms include long run times, warm air, and ice on the coil. We locate and repair the leak, then charge to manufacturer specs for reliable cooling.

Electrical failures

A weak capacitor or pitted contactor can stop a compressor or fan. Corroded wiring is common in outdoor units after heavy storms. We test components under load and replace only what is necessary, which restores cooling the same day in many cases.

Clogged condensate drains

Algae in the drain line triggers float switches that shut down the system. You may see water near the air handler or notice the unit running without cooling. We clear and flush the line, treat it, and verify slope so water drains freely.

Short cycling

If the system starts and stops every few minutes, the cause may be a failing sensor, an oversized unit, dirty coils, or a restriction. Short cycling wastes energy and wears out parts. We find the root cause and correct it before damage spreads.

Steps You Can Safely Do While You Wait

While the technician is on the way, a few actions can protect your home and reduce stress on the unit.

• Set the thermostat to 78°F and use ceiling fans
• Close blinds on sun‑facing windows in the afternoon
• Replace a clogged filter to restore airflow
• If there is ice, keep the system Off with the fan On until our tech arrives
• Place a towel under any small drip to protect flooring

These steps align with Energy Star style guidance and keep your system from fighting the heat.

Midlands Weather Matters: Why Systems Fail on the Hottest Days

In Columbia, Lexington, Irmo, and West Columbia, late afternoon humidity spikes stress AC systems. Return ducts in hot attics, clogged filters, and low refrigerant are magnified by 95°F days. Units that barely kept up in May often fail in July. A spring tune‑up is your best defense, paired with a proper filter schedule.

Inside a Professional Tune‑Up That Prevents Breakdowns

Preventative maintenance reduces emergency calls and lowers bills. A proper visit should include:

• Cleaning or replacing filters so the unit does not work harder than needed
• Inspecting electrical components and tightening connections for safe starts
• Checking refrigerant levels and testing for leaks to maintain efficiency
• Cleaning condenser coils for heat transfer
• Verifying thermostat calibration and sensor placement
• Flushing the condensate drain and testing the float switch

Industry guidance and our field data show that a tuned system runs cooler, uses less power, and lasts longer. Our website recommends at least one tune‑up per year, ideally in the spring, which aligns with Columbia’s cooling season.

Repair or Replace: Making the Right Call

Not every failure means a new system. We walk you through four quick factors.

1. Age and reliability
   • If your unit is 10 to 15 years old and has frequent failures, replacement may save money within a few seasons.
2. Cost of repair
   • A single high‑ticket repair over 30% of the cost of a new system is a signal to price an upgrade.
3. Efficiency
   • Older units can be costly to run. A new high‑efficiency system often lowers bills enough to offset payments.
4. Comfort and air quality
   • If you fight hot spots, humidity, or dust, a new system with duct updates and filtration can solve the root problems.

We provide apples‑to‑apples quotes, free estimates, and financing options. If repair is the smart move, we fix it. If replacement is better, we make it clear.

Pricing, Transparency, and What You Approve

Simple Homeowner Habits That Lower Bills and Avoid Breakdowns

Keep your system healthy with these Midlands‑tested habits.

1. Replace filters regularly
   • Standard 1‑inch filters often need monthly changes in summer. Do not oversize MERV without advice.
2. Seal air leaks
   • Weatherstrip doors and caulk windows to reduce heat gain.
3. Use fans wisely
   • Ceiling fans allow a higher set point without losing comfort. 78°F is a good summer target.
4. Clear the condenser
   • Keep two feet of space around the outdoor unit for airflow. Trim vegetation and rinse coils gently.
5. Schedule annual maintenance
   • A spring tune‑up catches small issues before they become outages and includes leak checks, electrical inspection, and efficiency testing.

Frequently Asked Questions

Why is my AC running but not cooling?

Low refrigerant, a dirty filter, frozen coils, or a failed capacitor are common causes. Replace the filter, check breakers, and set the fan to On if you see ice. If cooling does not return within 30 minutes, schedule a diagnostic visit.

Should I turn off the AC if the lines are iced?

Yes. Turn the system Off and set the fan to On to melt ice. Running while frozen strains the compressor and can cause major damage. After thawing, a technician can test airflow and refrigerant charge safely.

How often should I change my AC filter in summer?

Many Midlands homes need a new 1‑inch filter every 30 days during peak cooling. Homes with pets or construction dust may need more frequent changes. Ask a technician about the right MERV rating for your system.

What does an AC maintenance visit include?

A proper tune‑up includes cleaning or replacing filters, inspecting and tightening electrical components, checking refrigerant levels and leaks, flushing the condensate drain, verifying thermostat accuracy, and testing overall efficiency for safe, reliable cooling.
