An AC that stops cooling is more than an annoyance. Heat builds fast in a closed house, and humid summers make it feel worse. Foreverhighly Heating & Air helps you sort out what is happening before anyone touches the unit. We lay out the likely causes, the typical repair paths, and the questions worth asking.
Foreverhighly Heating & Air is a referral service. We do not do the repair. We connect you with independent HVAC providers in the Gaithersburg area, and the provider you choose diagnoses the system, gives you a written quote, and does the work. Many providers can respond quickly when the heat is a real risk, though availability varies. You stay in control the whole way. Read the steps below, run the quick checks, and then decide whether to call or request an estimate. Know your next step, then take it.
AC Stopped Cooling? Start Here
The house is warm and the vents are quiet. Stay calm and work in order. Facts first, then fix.
Run the five-minute check
- Set the thermostat to Cool, five degrees below the room temperature.
- Check the air filter. A clogged filter chokes airflow.
- Look at the breaker panel for a tripped AC breaker. Reset it once only.
- Check the outdoor unit. Clear leaves and debris, and make sure it has power.
- Look for ice on the copper line or water near the indoor unit.
Shut it off if you see these
- A burning or hot plastic smell.
- A breaker that trips again after one reset.
- Water pooling near the air handler or electrical panel.
- Grinding, screeching, or loud buzzing.
Turn the system off at the thermostat. Running a failing unit can turn a small repair into a big one. Request a callback to check provider availability in your area.
Signs Your AC Needs Repair
Warm or weak air
Vents blow warm air, or barely any. Common causes are low refrigerant, a failed capacitor, a dirty coil, or a blocked duct.
Odd noises and smells
Clicking, humming without a fan turning, or squealing all point to parts under strain. A musty smell often means a dirty drain pan. A burning smell means stop.
Ice, water, and sticky air
Ice on the coil means airflow or refrigerant trouble. Water around the indoor unit usually means a clogged condensate line. That is the small drain that carries moisture outside. If the house feels clammy while the AC runs, the system is not removing humidity.
Short cycling and rising bills
Short cycling means the AC starts and stops in brief bursts. It wears parts out and raises bills. Treat it as an early warning.
Is This Emergency AC Repair?
Sometimes it is. Heat is a real risk for babies, older adults, pets, and anyone with a medical condition. If that is your house, say so when you reach a provider. Many providers can respond quickly in those cases, but availability varies.
If everyone is safe and the house is just uncomfortable, a standard visit is fine. Open windows at night, close blinds by day, and run fans.
What Happens During a Repair Visit
Diagnosis comes first
The provider checks the thermostat, power, airflow, refrigerant pressure, and the electrical parts. This usually takes under an hour for a typical home.
A written quote before work
You should hear the cause, the fix, and the price before anything is replaced. Ask for it in writing. You can say no.
The repair and a test
The provider makes the repair, then runs the system to confirm it cools. Ask what was changed and keep the paperwork.
Common AC Repairs
Capacitor or contactor
A capacitor gives motors a power boost to start. A contactor is the switch that powers the outdoor unit. Both fail often and are modest repairs.
Refrigerant leak
Refrigerant is the fluid that carries heat out of your home. It is not used up like fuel. If it is low, there is a leak. A sound fix finds and repairs the leak, not just a top-up.
Clogged drain line
Algae and sludge block the condensate line. Clearing it is a routine job and can stop water damage near the unit.
Fan motor or compressor
The fan moves air across the coil. The compressor is the pump at the heart of the system. A fan motor is a mid-range repair. A compressor is the costly one.
Repair or Replace?
Signs that point to repair
- The unit is under about ten years old.
- The problem is one part, such as a capacitor or fan motor.
- The quote is small compared with a new system.
Signs that point to replacement
- The system is 12 to 15 years old or more.
- The compressor has failed or the coil leaks.
- Repairs keep coming back each summer.
- The system uses an older refrigerant that is being phased out.
A common rule of thumb: if a repair costs half or more of a new system, ask for a replacement quote too. Compare both before you decide.
Questions to Ask the Provider
- Is the diagnostic fee applied to the repair if I go ahead?
- Can I get the quote in writing before work starts?
- What is the cause, and what else might fail soon?
- Are parts and labor covered by a warranty, and for how long?
- Is the provider licensed and insured in my state?
Older Homes, Basements, and Humid Summers
In many colonial and split-level homes, the air handler sits in a basement or tight closet. That makes drain leaks easy to miss. In rowhouses, long duct runs can hide airflow problems. Our humid summers push every system hard, so small faults show up fast.
Your Next Step
Run the checks, note what you saw, and decide how urgent it is. Then reach out to a provider. Some insurance policies may cover sudden damage from a failed system, so check your policy. Providers can often help document damage for a claim. Request a callback to talk it through.
What's Included
Cause Check
A provider traces the fault through power, airflow, refrigerant, and electrical parts, then explains what failed and why.
Written Quote
You see the price and the plan before any part is replaced.
Common Fixes
Capacitors, contactors, drain lines, fan motors, and refrigerant leaks are the repairs providers handle most.
Repair-or-Replace Advice
If the system is old or the repair is large, ask for a replacement quote to compare.

No obligationAC Repair FAQ
Why is my AC running but not cooling?
Common causes are a dirty filter, a failed capacitor, low refrigerant from a leak, or a frozen coil. Check the filter and look for ice. If the cause isn't clear, a provider can diagnose it.
How much does AC repair cost?
Typical U.S. repairs run from about $150 for small parts to $1,500 or more for leaks and major components. Costs vary by job, so ask for a written quote before approving any work.
Should I repair or replace my air conditioner?
If the unit is under ten years old and only one part failed, repair often makes sense. For older systems, a failed compressor, or repeat breakdowns, compare a replacement quote before deciding.
