Quick Safety Checks Before You Start

A few fast checks can save time and prevent damage.

Set the thermostat to Cool and Auto, not On. Lower the setpoint by 3 to 5 degrees.
Listen for two sounds: indoor blower running and outdoor fan/compressor running.
Look for ice on refrigerant lines or the outdoor unit. If you see ice, turn the system Off and set the fan to On for 30 minutes to thaw.
Check for water at the indoor unit. A clogged drain can trip a float switch and stop cooling.

If you smell burning, hear popping at the panel, or the outdoor fan does not start after several minutes, stop and call a pro. Kaminer Heating And Cooling operates a true 24-hour service line with rapid response throughout the Midlands.

Step-by-Step: How To Fix an AC Not Blowing Cold Air

Work through these homeowner-safe steps in order. Many no-cool calls in Columbia, Lexington, and Irmo are solved by 1 to 3 below.

1) Thermostat settings

Mode should be Cool.
Fan should be Auto. Fan On can push room-temperature air that feels warm.
Replace thermostat batteries if the screen is dim or blank.
Smart thermostat users: temporarily disable schedules and eco modes.

If the thermostat is unresponsive or randomly resets, you may have a low-voltage issue that needs professional diagnostics.

2) Dirty air filter

A clogged filter starves airflow, causes coil icing, and kills cooling. Replace 1-inch filters every 30 to 60 days during high pollen season in the Midlands. For 4-inch media filters, check every 3 months.

Remove the filter from the return grille or air handler.
If it looks gray or packed with dust, replace it with the correct size and MERV rating.
After replacement, allow 15 to 30 minutes for the coil to thaw and cooling to resume.

"My ac quit working yesterday they were out within a couple of hours and had it back up and cooling. My tech was very polite and very professional."

3) Outdoor unit airflow

Wind-blown pine straw, leaves, and grass clippings choke the condenser and raise pressures.

Shut power Off at the outdoor disconnect.
Gently hose from the inside out if accessible, or from the top down to rinse debris off the coil fins.
Keep 18 to 24 inches of clearance around the unit. Trim shrubs.

If the outdoor fan is not spinning but hums, the capacitor could be bad. That is a pro repair.

4) Circuit breakers and switches

Check the indoor air handler breaker and the outdoor condenser breaker in the main panel.
Verify the furnace or air handler service switch is On.
Reset a tripped breaker once only. If it trips again, call a licensed tech.

5) Condensate drain and float switch

High humidity in West Columbia and Cayce can load the drain with algae.

Look for a small PVC pipe near the indoor unit. If water is pooled, the float switch may have shut the system down.
Clear the drain with a wet/dry vac at the outside drain termination for 2 to 3 minutes.
Pour a cup of white vinegar into the cleanout to slow algae growth.

6) Return and supply vents

Walk every room in your home in Blythewood, Irmo, and Lexington.

Open all supply registers at least halfway.
Do not block returns with furniture or rugs.
Closed doors can unbalance airflow in older duct systems.

7) Icing and low airflow symptoms

If you see frost or hear a hiss at the indoor coil, turn the system Off and set the fan to On for 30 to 60 minutes to thaw. After thawing, try cooling again. If ice returns, you may have a dirty coil, low refrigerant, or a failed blower motor. These require pro service.

"Absolute lifesavers!! ... When my AC went out during this brutal heat wave, I was honestly panicking. Even though the schedule was completely booked up, Kaminer made it a priority to get out to my house the same day. ... My family and I are sleeping comfortably tonight because he went the extra mile."

What Your Technician Will Check and Why It Matters

A thorough visit prevents repeat breakdowns and protects warranties. Our inspections go beyond quick fixes using state-of-the-art diagnostic equipment.

During maintenance and diagnostic visits we focus on comprehensive inspection and cleaning processes that include:

"Cleaning and Replacing Filters"
"Inspecting Electrical Components"
"Checking Refrigerant Levels"

For heating equipment, our maintenance service provides:

"Full system inspection"
"Cleaning vital parts"
"Performance checks"
"Filter replacement guidance"
"Actionable maintenance advice"

On AC repair calls, expect your Kaminer technician to:

Verify thermostat and control board signals.
Measure static pressure and temperature split to confirm airflow health.
Test capacitors, contactors, and motors under load.
Check refrigerant charge according to manufacturer specs, not guesswork.
Inspect the condensate system for clogs and float switch function.
Examine ductwork for leaks or crushed runs that rob cooling.

"They diagnosed the problems, explained everything in a way that made perfect sense, and within 2 weeks we are now up and running with a brand new A/C and completely repaired duct work... They stand behind their work and the warranty options on parts and labor plus yearly maintenance are affordable and so worth it."

Common Causes of Warm Air and Typical Fixes

Dirty filter or coil: Clean or replace filters. Schedule a professional coil cleaning if needed.
Low refrigerant from a leak: Find and fix the leak, then recharge to spec. Do not top off without leak repair.
Failed capacitor or contactor: Replace the faulty part. These are common in high-heat months.
Clogged drain or tripped float: Clear the drain and reset the switch.
Duct issues: Repair crushed or disconnected ducts. Seal leaks to restore airflow and efficiency.
Thermostat or control failure: Calibrate, replace batteries, or replace the thermostat.

In many Midlands homes, a mix of pollen, dust, and cottonwood fluff clogs coils in May and June. Quick coil cleaning plus a new filter often restores cold air within one visit.

What Will It Cost and How Long Will It Take?

Costs vary by cause and parts availability. Here is what drives price and timeline:

Diagnostic and minor electrical repairs
- Capacitors, contactors, or loose connections are often same-day fixes.
- Parts usually in truck stock during peak season.
Refrigerant issues
- Finding and repairing leaks takes time. Expect pressure tests and electronic leak detection.
- Some systems use phased-out refrigerants. We will provide options with clear pricing.
Drain and safety switch problems
- Clearing lines is quick. Slime-heavy drains may need extra cleaning and preventative tablets.
Blower or condenser fan motors
- Common models are same-day. Special-order motors can take 1 to 3 days.
Duct repairs
- Simple reattachments are same-day. Larger corrections may be scheduled.

We provide free estimates before major work and back repairs with our satisfaction guarantee. Ask about financing for bigger repairs or system upgrades.

"Once again, Kaminer saves our day. It is miserably hot out and in the downstairs area in my house. One of our 2 AC unit's compressors was entirely shut down. Michael cleaned the coils, got the compressor back in working order, and my house cooling down within an hour. Same day service, no less."

Prevent It From Happening Again: Pro Tips for the Midlands

Change filters on a schedule. Set a calendar reminder every 30 to 60 days in summer.
Keep 2 feet of clear space around the outdoor unit. Rinse coils after lawn mowing.
Pour a cup of white vinegar in the condensate cleanout every month in peak humidity.
Use a smart thermostat schedule that does not overwork the system during the hottest hours.
Seal duct leaks in attics and crawlspaces. This can improve comfort and reduce dust.
Consider air quality upgrades like HEPA or whole-home filtration to reduce coil fouling.

For year-round reliability, consider a maintenance plan. Regular tune-ups extend equipment life and preserve manufacturer warranties. Our plans include annual AC and heating inspections and tune-ups tailored to Midlands weather.

Frequently Asked Questions

Why is my AC running but not cooling?

Common causes are a dirty filter, frozen coil, outdoor unit blockage, low refrigerant, or a failed capacitor. Start with filter and thermostat checks, then call if problems persist.

Is it safe to run my AC if the coil is iced?

No. Turn the system Off and set the fan to On to thaw for 30 to 60 minutes. Running while frozen can damage the compressor and increase repair costs.

How often should I change my AC filter in Columbia?

During high pollen and summer heat, check 1-inch filters every 30 to 60 days. Larger media filters can last up to 3 months. Replace sooner if visibly dirty.

What maintenance prevents warm-air problems?

Annual tune-ups with coil cleaning, electrical checks, and refrigerant level verification. Our visits include cleaning or replacing filters, inspecting electricals, and checking refrigerant.

Yes. Kaminer Heating And Cooling operates a true 24-hour service line and provides rapid emergency response across the Midlands.
