AC Repair Services for a Home That Stopped Cooling
Request an estimate today
An air conditioner rarely fails all at once. It starts with a weak breeze, a strange noise, or a house that stays warm after sunset. In hot, humid weather, that small fault keeps working against you. The system runs longer, the air feels sticky, and parts that were only tired begin to wear out.
Cmlog Heating & Air is a referral service. We do not repair air conditioners. We take your request and connect you with an independent provider in our network who serves the Houston area. The provider inspects the system, explains the problem, and gives you a written quote. This page walks through what happens hour by hour, which repairs are common, and what to ask before you say yes. There is no obligation to hire anyone.
AC Stopped Cooling? Start With These Checks
Think of a bicycle tire with a slow leak. Patch it early and you are done. Ride on it and the rim bends. An AC works the same way. Small faults grow. A few minutes of checking can tell you a lot.
Look at the thermostat
Set it to cool and drop it five degrees below the room temperature. If the screen is dim or blank, try fresh batteries. This is a simple cause and a common one.
Check the breaker and the filter
Find the AC breaker in your electrical panel. If it has tripped, reset it once. If it trips again, stop and leave it off. Then pull out the air filter. A gray, clogged filter blocks airflow and makes the whole system strain.
Know when to switch it off
Turn the system off at the thermostat if you see ice on the pipes, hear grinding or squealing, or smell something burning. Running a damaged unit can turn a small repair into a big one.
What Happens Hour by Hour
Picture a car climbing a hill with low oil. It may make it for a while, but every mile adds wear. Your AC behaves the same way when something is wrong.
The first few hours
The house warms slowly. The system may run nonstop trying to catch up. In summer, a hot attic pushes heat down through the ceiling all afternoon, so the rooms upstairs and along outside walls feel it first.
The first full day
Humid air settles into fabric, bedding, and walls. A weak system that keeps running can ice over its indoor coil. Ice blocks airflow, and that makes the first problem worse. This is the stretch where a fix often stays simple.
Days two and three
Indoor humidity stays high and a musty smell can show up. If the drain line is clogged, water may back up near the indoor unit and stain a ceiling or floor. Sleep gets harder, and older family members and pets feel the heat more.
After a week
Damp surfaces can start to grow mold. A compressor that ran under strain may fail, and it is one of the pricier parts. What could have been a small swap now becomes a bigger choice.
Signs Your AC Needs Repair
Like a cough that will not go away, these signs are your system asking for attention:
- Air from the vents feels warm or only slightly cool
- The outdoor fan does not spin, or the unit hums but does not start
- Water pools near the indoor unit
- Ice forms on the copper line or the coil
- The system turns on and off in short bursts
- Your power bill climbs with no change in habits
Emergency AC Repair During Storm Season
Heavy downpours and tropical storms can bring power surges and flooded equipment pads. If the outdoor unit sat in water or the power flickered and the AC now stays silent, leave it off. Restarting it can damage the parts. Many providers can respond quickly when demand is high, but availability changes with the weather and the day.
Request a callback to check provider availability for emergency AC repair in your area.
Common AC Repairs
A repair is often one small part, a bit like replacing a worn fuse instead of rewiring the house.
Capacitor and contactor
The capacitor gives the motors a boost to start. The contactor is the switch that powers the outdoor unit. When either wears out, the fan or compressor will not start. These are common parts in hot climates.
Refrigerant leaks
Refrigerant is not used up like fuel. If the level is low, there is a leak. A provider should find the leak, not only add more.
Frozen coil
A dirty filter, low airflow, or low refrigerant can ice the coil. The fix depends on the cause, so thawing alone is only a pause.
Clogged drain line
In humid weather, your AC pulls gallons of water from the air. If the drain line clogs, that water has nowhere to go. Many systems shut off to protect the house.
What Happens During a Repair Visit
A good visit is like a doctor checking symptoms before writing a prescription. The provider listens to what you noticed, checks power and airflow, tests the electrical parts, and measures temperatures. Then they explain what they found and give a written quote. You decide what happens next.
Repair or Replace?
A rule of thumb: if the system is under about ten years old and the fix is modest, repair usually makes sense. If it is older, needs a major part, or breaks down again and again, ask the provider to compare both paths. Ask for each option in writing.
Questions to Ask the Provider
- What exactly failed, and can you show me?
- Is the quote written, with parts and labor listed?
- Is the visit fee applied to the repair if I go ahead?
- What warranty comes with the part and the labor?
- Is the provider licensed and insured in my state?

No obligationAC Repair Services FAQ
Why is my AC running but not cooling the house?
Common causes include a clogged filter, an iced coil, low refrigerant, or a failed outdoor fan. Check the filter first. If air is still warm, switch the system off and ask a provider to inspect it.
Is it safe to keep running a struggling AC?
Usually not. A system with ice, grinding noises, or a burning smell can be damaged further. Turn it off at the thermostat and have a provider look at it.
Will my insurance pay for an AC repair?
Wear and tear is usually not covered. Some policies may cover sudden damage, such as a storm surge. Check your policy, and providers can often help document damage for a claim.
