Most AC breakdowns in Arlington start with a small part: the run capacitor. It helps start the compressor and condenser fan, loses strength slowly over the years, and tends to give out on the hottest afternoon, which is why so many service calls begin with an outdoor unit that hums while the fan sits motionless. Other frequent culprits include contactors with pitted, burned points, fan motors whose bearings have run dry, slow refrigerant leaks that steadily rob capacity, and evaporator coils that turn into blocks of ice once a dirty filter chokes the airflow.
At Arlington HVAC, every AC repair starts with measurement. Capacitors are metered against the rating on the label. Amp draws on the compressor and fan motor are compared to the data plate. Refrigerant charge is judged by superheat and subcooling, not by pressure readings alone, and any icing prompts a look at the evaporator coil, blower wheel, and filter. This matters because a single warm-air symptom can hide four different faults at four very different prices, and a refrigerant top-off that ignores the leak is just a short-term rental on cold air.
Straight answers are part of every visit. If an aging system's compressor has failed, we explain the repair-versus-replacement math plainly and let you decide. Most of the time, though, the fix is simpler, and because our trucks stock capacitors, contactors, fan motors, hard-start kits, and condensate pumps, cooling is usually restored before we leave. We work on central air, heat pumps, and ductless mini splits from all major brands. Need AC repair in Arlington? Call (682) 214-6720 and an experienced technician will be on the way.

How Much Does AC Repair Cost in Arlington?
Most air conditioner repairs in Arlington land between $150 and $650. Where you fall in that range depends almost entirely on which component failed. Arlington HVAC diagnoses the problem first and gives you a written price before any work starts.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Capacitor replacementMost common repair, usually same visit | $150–$400 | The most common AC failure; outdoor unit hums but won't start |
| Contactor replacementWorn relay that stops the condenser from starting | $150–$350 | Burned or pitted switch that powers the outdoor unit |
| Condenser fan motorFan won't spin, unit overheats and shuts down | $300–$700 | Fan won't spin, unit overheats and shuts down |
| Refrigerant leak repair + rechargeVaries with where the leak is and how much charge is lost | $300–$1,500 | Depends on leak location and refrigerant type |
| Evaporator coil replacementCorroded or leaking indoor coil | $1,000–$2,500 | Corroded or leaking indoor coil |
| Compressor replacementLargest single repair; often weighed against a new system | $1,500–$3,000 | On systems past 10–12 years, replacement usually makes more sense |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.
What Moves the Cost Up or Down
- How old the unit is and how easy its parts are to source
- The type of refrigerant, since older R-22 systems cost far more to recharge
- Timing, such as same-day or after-hours service versus a scheduled visit
- Access to the equipment, like rooftop units or tight attic air handlers
On older systems we always compare the repair against a replacement, so you can make the call with real numbers. Call (682) 214-6720 to get your price.
Warning Signs for AC Repair
Catching these issues early helps you avoid costly problems and protect your property. Keep an eye out for the following clues that it's time to bring in an expert:
- Frost or ice forming on the copper lines or the indoor coil
- The system short-cycling every few minutes without cooling the house
- Breaker trips or a burning odor at startup
- Clicking or humming outside with no fan movement
- Water dripping from the indoor unit or showing up on the ceiling below
- Rising electric costs paired with a sticky, uncomfortable house
- Hissing or bubbling sounds that suggest a refrigerant leak
- Vents blowing air that is barely cooler than the room
Act Before It Gets Worse
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. Call Arlington HVAC at (682) 214-6720 at the first sign of trouble.
Frequently Asked Questions About AC Repair
Why Professional AC Repair Matters
Air conditioning repair concentrates several hazards in one cabinet. Capacitors store a charge that bites long after the breaker is off, condensing units run on 240-volt circuits, and the refrigerant loop is a sealed, pressurized system that federal rules do not permit venting to the air; working on it takes gauges, a recovery machine, and a vacuum pump, not a can from the internet. The diagnostic traps are just as real: a frozen coil looks like a refrigerant problem but is just as often an airflow problem, and refilling a leaking system without repairing the leak wastes money while acid and moisture quietly damage the compressor.
Professional repair gets the whole picture. Our experienced technicians meter electrical components instead of swapping them, weigh charge decisions against measured superheat and subcooling, find leaks with detectors and dye rather than assumptions, and check the filter, blower, and duct static pressure whenever airflow is suspect. That is the difference between a repair that holds through the season and a parts-cannon fix that calls you back in three weeks. And when the system genuinely is not worth saving, we tell you that plainly too, with numbers instead of pressure.
Our AC Repair Process
We work through a clear, repeatable process so nothing gets overlooked on your property. Here's a look at each step our Arlington HVAC team takes:
Testing First
Capacitors, the contactor, motors, and amp draws are all measured, the charge is checked through superheat and subcooling, and the coil, filter, and drain are inspected so the real failure is found.
Clear Explanation & Price
We show you what failed and why, then give a firm price before any work begins. If the compressor or coil points toward replacement instead, we lay out the honest math.
On-the-Spot Fix
Most AC fixes happen right away. We carry capacitors, contactors, fan motors, and other high-failure parts, so you are rarely left waiting on a parts order.
Cooling Performance Check
Before we leave, we measure the temperature split, recheck amp draws and refrigerant charge, flush the condensate line, and run the system through a complete cooling cycle.

Call (682) 214-6720 TodayMaintenance Tips for AC Repair
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Here are our expert recommendations:
- Keep shrubs two feet from the outdoor unit and gently rinse its coil each spring
- Leave vents open in every room, since closing them strains the blower
- Start each cooling season by flushing the condensate line so algae cannot block it
- Schedule a spring tune-up so weak parts are caught before summer arrives
- Change the filter monthly during cooling season; starved airflow is how coils freeze
- A new buzz or click at startup often means a weak capacitor, so call before it fails
- Shade is fine, but do not box in the outdoor unit with fences or covers
DIY vs. Professional AC Repair
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Refrigerant | Adding refrigerant while it keeps leaking | Leak repaired and correct charge restored by weight |
| Shock Risk | Risk of shock from 240V and stored charge | Power verified off, capacitors discharged |
| Iced Coils | Thawed and refrozen on repeat | Root cause found: airflow or charge |
| Troubleshooting | Guesswork on faults that look the same | Instrument readings, not hunches |
| Parts | Parts that are almost the right rating | Specs matched to the equipment data plate |
| Outcome | Cold air until the next heat wave | Tested and confirmed under load |
