AC Repair in Houston - On-Site Today, Diagnosis First

Trusted AC Repair for Houston Homeowners

When your air conditioner stops cooling in a Houston summer, the house gets uncomfortable fast. Pews of sweat on the back of the neck by 10 a.m. Kids can’t settle. Pets pant by the back door. A working AC in Houston isn’t a convenience; it’s how families keep the home livable when the heat index pushes past 100. Most AC repairs in Houston run between $150 and $650, and we’re on the road the same day you call. Luis Serrano and the crew at Meadowsweet Heating and Air Houston have been keeping homes cool since 2004, under the Cedarwell umbrella. A live person answers 24/7 at (346) 201-5395, and every visit starts with a written price before any work begins.

AC Maintenance

AC Maintenance is the scheduled care that keeps your cooling system from failing on the hottest afternoon of the year. In Houston, we recommend it twice annually: once before summer and once after, because the unit works harder here than nearly anywhere else in the country. Meadowsweet Heating and Air Houston performs a full maintenance visit for $80 to $200, depending on system size and age. That visit includes cleaning the condenser coil, checking refrigerant levels, tightening electrical connections, inspecting the condensate drain, and measuring airflow. The goal is catching small wear before it becomes a $650 repair.

Spring Tune-Up Before the Heat Hits

Houston’s first 90-degree day sneaks up. Scheduling maintenance in March or April means your AC is ready before the thermal wall arrives. A pre-season check finds weak capacitors, dusty coils, slow drains, and low refrigerant while the parts are still easy to replace. You avoid the July scramble.

Post-Summer System Check

After six months of near-continuous cooling, the system needs attention. A fall visit clears debris, checks belts and bearings, and confirms the unit made it through the season without hidden damage. It also gives us a record of system health year over year, which matters for warranty and longevity.

AC Service

AC Service is the broader category of professional attention your cooling system receives from a trained technician, whether that’s maintenance, diagnosis, or repair. You need it when the system runs longer than usual to reach the thermostat setting, makes a sound it didn’t make last week, or cycles on and off too quickly. Meadowsweet Heating and Air Houston sends a background-checked, uniformed technician who starts with a careful diagnostic pass, not a quote for parts you may not need. A written price comes before any work starts, every time.

A Systematic 21-Point Diagnostic

Before we touch a single component, the technician runs pressure checks, electrical measurements, and temperature-drop readings across the system. The goal is to find the root cause, not patch the symptom. You see the measurements, and the price quote reflects the actual fault. No mystery charges.

Clean Entry, Clean Exit

Shoe covers go on at the door. Drop cloths go down before tools come out. When the job is done, we photograph the cleanup and share it with you before the crew leaves. That’s the Cedarwell Care Promise in practice: the house looks like the repair never happened, except the AC works.

AC Unit Repair

AC Unit Repair means addressing a mechanical or electrical fault in the outdoor condenser or indoor air handler so the system cools again. In Houston, common failures include failed fan motors, clogged condenser coils, seized compressors, and blown control boards. Repair pricing runs $150 to $650, depending on the failed part and system complexity. Meadowsweet Heating and Air Houston services nine major brands, which means we carry or can quickly source the right part for Carrier, Trane, Lennox, and Goodman systems, among others.

Condenser and Compressor Issues

When the outdoor unit runs but the air blowing inside isn’t cold, the condenser or compressor is often the problem. We test capacitors, contactors, and compressor windings in sequence to isolate the failure. A single failed part is replaced; we don’t sell a compressor replacement when a capacitor swap fixes the issue.

Indoor Air Handler Repairs

The air handler is the indoor half of the system: the blower motor, evaporator coil, and control board. A failing blower motor makes the house feel stale, cool in one room and warm in another. A freezing evaporator coil usually means airflow or refrigerant trouble. We fix the cause, thaw the coil safely, and confirm the system drains properly before we leave.

AC Capacitor Replacement

AC Capacitor Replacement is a focused repair where a technician replaces the small cylindrical component that supplies the starting jolt and running current to the compressor and fan motors. The capacitor is one of the most common failures in Houston because heat and cycling stress it over time. When it fails, the compressor may hum but not start, or the outdoor fan won’t spin. Capacitor replacement typically costs $150 to $300, including the part and service call. It’s a same-day fix in most cases.

Heat Is the Main Culprit

Houston’s sustained high temperatures bake capacitors. The internal dielectric material degrades, the capacitor loses its microfarad rating, and the motor it serves can’t stay running. We test every capacitor with a digital capacitor meter before condemning it. If it’s marginal, you get a clear recommendation, not pressure.

Dual-Run Capacitors on Most Units

Many Houston systems use a dual-run capacitor that serves both the compressor and the outdoor fan. When one side fails, both circuits need attention. We replace dual-run capacitors with units matched to the published microfarad rating on the old part. The goal is a cool house tonight, not a callback in three weeks.

AC Recharge

AC Recharge is the process of restoring the refrigerant level in a cooling system to the manufacturer’s specified charge. It’s needed when the system has lost refrigerant, which in a sealed system means a leak exists somewhere, usually at a brazed joint, a Schrader valve, or an evaporator coil. A proper recharge includes locating and repairing the leak first, since adding refrigerant without fixing the leak only postpones the problem. Recharge costs range from $200 to $650, depending on refrigerant type and how much is needed.

R-410A vs R-22 Systems

Older Houston homes may still run R-22 systems, and that refrigerant is expensive now that production has been phased out. If your R-22 system has a leak, the cost of a full recharge can exceed the value of continued repairs. We walk through the numbers honestly, because sometimes a new system is the better financial choice.

Finding Leaks Before Recharging

We use an electronic leak detector and, where needed, a nitrogen pressure test to find the exact point of refrigerant loss. Recharging a system with an active leak wastes your money and releases refrigerant into the atmosphere. The leak gets repaired, the system gets pressure-tested again, and only then do we add refrigerant.

Emergency AC Repair

Emergency AC Repair is a same-day, often same-afternoon service call for a cooling system that has completely failed during extreme Houston heat. A live person answers our phone 24 hours a day, 7 days a week, including nights, weekends, and holidays. No voicemail queue, no answering service that promises a callback. When you call (346) 201-5395, you get a person who can schedule a technician. Emergency repair pricing follows the same $150 to $650 range, with a written price before any work starts, even at 2 a.m.

Heat Index Above 100 Degrees

When the heat index crosses into triple digits, a failed AC becomes a genuine health concern, especially for infants, elderly family members, and people with respiratory conditions. We treat emergency calls as emergencies. Trucks are stocked with common capacitors, contactors, fan motors, and refrigerants, so many failures can be fixed in one visit.

Evening and Weekend Failures

AC failures don’t respect business hours. A compressor that seizes on Saturday evening needs attention before Sunday afternoon. Our technicians work evenings and weekends, and the emergency rate doesn’t change because it’s 9 p.m. The same written pricing standard applies. The same shoe covers and drop cloths go into effect. The same 365-Day Done Right Promise stands behind the repair.

AC Not Blowing Cold Air

AC Not Blowing Cold Air is the most common summer breakdown we see in Houston, and its causes range from simple to serious: a dirty air filter, a tripped breaker, low refrigerant, a failed capacitor, or a frozen evaporator coil. The average repair for an AC that isn’t blowing cold runs $150 to $500, and most are resolved in one visit. When we arrive, the technician measures return air temperature and supply air temperature to confirm how much cooling has been lost, then traces the system from thermostat to condenser. No guesswork, just a systematic diagnostic.

The Frozen Coil Problem

A frozen indoor coil blocks airflow and makes the system blow warm air while it ices over. Causes include a dirty filter, low refrigerant, or a failing blower motor. We thaw the coil carefully, fix the underlying cause, and verify the condensate drain is clear so water doesn’t damage the floor or the air handler cabinet.

Thermostat and Electrical Failures

Sometimes the AC is fine and the thermostat has failed, or a contactor has pitted and no longer closes the circuit. The easiest checks come first: thermostat batteries, settings, and breakers. If those pass, we measure voltage at the contactor and capacitor. A $40 part and precise diagnosis get the house cooling again.

Brands We Service

Our technicians work on Carrier equipment daily. We’ve replaced Carrier capacitors, contactors, evaporator coils, and control boards across Houston neighborhoods from Bellaire to Atascocita, and we keep the common OEM parts on the truck. Carrier’s higher-efficiency units reward precise refrigerant charging, and we use the manufacturer’s subcooling and superheat methods rather than guessing by gauge pressure alone.

Trane and Lennox systems show up regularly too. Trane’s all-aluminum coils and Lennox’s variable-speed blowers each have their own diagnostic signatures, and our technicians know the difference. Whether the system outside your house is a Trane, Lennox, Goodman, or any other make, we diagnose it the same way: measure first, recommend second, and always with a written price before work begins. Our home page covers the full range of services.

Signs You Need a Pro Right Now

• Warm air from the vents while the thermostat says “cool.” This means the compressor isn’t running, the refrigerant is low, or the reversing valve has failed. It won’t fix itself, and running the system this way can damage the compressor.
• Ice on the refrigerant lines or the indoor coil. Ice means airflow or refrigerant trouble, and the ice itself blocks cooling. Continuing to run a frozen system can send water into the air handler and onto your floor.
• A burning smell or visible sparks from the outdoor unit. Electrical components like capacitors and contactors can overheat. Shut the system off at the breaker and call us.
• The system short-cycles, turning on and off every few minutes. This often means a failing capacitor, low refrigerant, or an improperly sized unit. Short-cycling drives up energy cost and wears parts faster.
• Humming from the condenser but no cooling. The compressor is trying to start and can’t. Letting it hum can overheat and destroy the compressor, which turns a $200 repair into a $3,500 replacement.

Our Process, Step by Step

1. 1
   Listen and gather information. When you call, we record the symptoms and ask the right questions: how old is the system, what’s the thermostat showing, has anything changed recently. This helps the technician arrive with the likely parts on board.
2. 2
   Arrive and protect your home. The technician parks, greets you, and puts on shoe covers before entering. Drop cloths go under the equipment area, and the crew follows the C.A.R.E. values: clean up, ask before moving anything, respect your time, explain the price.
3. 3
   Diagnose with instruments, not guesses. We measure refrigerant pressures, electrical draws, capacitor microfarads, temperature splits, and airflow. The readings point to the fault. You’re shown what we found, and we explain what it means in plain language.
4. 4
   Present a written price, then get your approval. The price is written before any work starts, and it includes the part, the labor, and the service call. You decide. There’s no obligation and no pressure from a commission-based technician. Our techs aren’t paid on what they sell.
5. 5
   Repair, test, and leave the house clean. The repair gets completed, the system is started and verified, and the work area is cleaned. We photograph the cleanup and share it with you. The 365-Day Done Right Promise stands behind the work.
