Seasonal tune-up and full diagnostic on your Carrier, Trane, or Goodman system - readings shown to you before any repair is proposed
Diagnosis first, numbers second - you approve the repair price before a single part goes in.
Trusted AC Repair Nationwide
When your air conditioner quits in the middle of a heat wave, you need a repair crew that shows up inside the window, puts the price in writing before touching a screwdriver, and stands behind the work for a full year. That is how Dalton Heating & Air has operated since 2003 under The Garrison Standard. Learn more about how much AC repair costs; most repairs run $150 – $650 depending on the part that failed. A capacitor, a contactor, a refrigerant recharge: each one has a different fix and a different price, and you will know yours before we start. We answer the phone with a live person 24 hours a day, 7 days a week. Call (361) 306-9515 and get a technician scheduled for same-day or next-day arrival. Every repair is guaranteed in writing for a full year, and if it fails within that time, we return at no charge. No fine print, no upgrade fee, no runaround. Marco Benitez leads a team that services all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

AC Maintenance
AC Maintenance is the scheduled checkup-see our AC repair maintenance schedule: what to do and when-that catches small problems before they become expensive AC repair calls. You need it once a year, ideally in spring before the cooling season starts, though a fall checkup is better than none. A Dalton Heating & Air maintenance visit includes cleaning the condenser coil, checking the refrigerant charge, testing the capacitor, tightening electrical connections, and measuring the temperature drop across the coil. Tune-ups run $80 – $200, which is the least expensive way to keep a system alive past the 10-year mark. The technician writes down everything that was checked and everything that was found, so you can see the condition of your system in plain language.
What a Tune-Up Caught Last Summer
A homeowner called us because their unit was running but the house would not cool below 78 degrees. The AC Repair Maintenance Checklist for Los Angeles Homeowners maintenance visit revealed a capacitor that was delivering only 70 percent of its rated microfarads. Replacing it cost under $200 and saved the compressor from cycling itself to death. That is the difference between a $150 part and a $4,500 compressor swap.
Why Annual Visits Lower Long-Term Cost
Dirty coils force the compressor to work harder, which raises your electric bill and shortens the system’s life. A maintenance visit costs less than two months of that extra energy use in many homes. We also document every visit, so if a warranty claim comes up later, you have a service history from a single company.
AC Service
AC Service is the umbrella term for any professional work on your cooling system, from a simple tune-up to a complex diagnostic repair. When your unit is making noise, short-cycling, or failing to hit the set temperature, you need a service call. Dalton Heating & Air sends a background-checked, uniformed technician who starts by listening to what the unit is doing, then tests the components in sequence: thermostat signal, capacitor, contactor, compressor windings, refrigerant pressures, and airflow. Service visits are quoted in writing before any work begins, and the repair is guaranteed for a full year. Most AC service calls fall between $150 and $650 depending on what the diagnostic finds.
The Diagnostic First, the Quote Second
No technician should hand you a repair price before the unit has been opened and tested. Dalton runs the full diagnostic, walks you through what was found, and presents a written price. You approve it or you do not, and there is no charge to walk away from a repair estimate you never authorized.
No Upsell Mentality, No Commissioned Pressure
Our technicians are not paid on what they sell. That means when a capacitor is the problem, the invoice says capacitor. When a coil leak is the problem, you will see it on the gauge set and in the written quote. If the system is too old to repair responsibly, we will tell you that too, and show you the numbers. See our home page for more on how we approach every service call.
AC Unit Repair
AC Unit Repair covers the mechanical and electrical fixes inside the condensing unit and the air handler: capacitors, contactors, fan motors, control boards, drain pans, and coils. You need it when the unit is running but not cooling, making a buzzing or grinding sound, or tripping the breaker. Dalton Heating & Air stocks common OEM and equivalent parts on the truck for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so many repairs are completed same-visit. Pricing runs $150 – $650 for most part-level repairs. The written quote lists the part, the labor, and the total before we turn a wrench.
When Repair Beats Replacement
A failed capacitor, contactor, or fan motor is a component-level repair, and the fix typically costs a fraction of a new system. If the compressor itself is dead and the unit is over 12 years old, replacement often makes more financial sense. We show you both numbers and let you decide with the facts in front of you.
The Parts We Keep on the Truck
Our trucks carry the most common failure points: dual-run capacitors, single-pole and double-pole contactors, fan motors, and hard-start kits. That inventory means we fix more units on the first visit. Fewer return trips, less waiting in a hot house.
AC Capacitor Replacement
AC Capacitor Replacement is one of the most common AC repairs we do, and it is also one of the least expensive. You need it when the unit hums but the fan does not spin, or the compressor struggles to start, or the system shuts off on its own after a few minutes. The capacitor is a small cylinder that stores the electrical burst the fan motor and compressor need to start. When it weakens, the whole system labors. Dalton Heating & Air replaces capacitors in every major brand and tests the new part with a capacitance meter before we button the unit back up. This repair usually runs $150 – $350 depending on whether it is a single-run or dual-run capacitor.
Symptoms of a Capacitor on the Way Out
A unit that starts sometimes and not others is a classic failing capacitor. You might also hear a clicking sound at the contactor, or see the fan spinning slower than it should. Running the system in that condition can overheat the compressor, and compressor replacement costs thousands.
Why Testing After Install Matters
We check every capacitor with a digital meter before and after installation, verifying the microfarad rating matches the manufacturer spec. A capacitor that tests 10 percent outside spec is considered failed. Skimping on this test is how some crews leave a unit that works for a month and then quits again.
AC Recharge
AC Recharge is the process of restoring the correct refrigerant level in your system, the cooling fluid that absorbs heat from inside your home and releases it outdoors. You need it when the system is running but the air coming out of the vents is lukewarm, or the lines at the outdoor unit are frosted over, or cooling has gradually declined over weeks. Here is the important part: refrigerant does not get used up. If the charge is low, there is a leak, and adding refrigerant without finding the leak is a temporary fix. Dalton Heating & Air performs a leak search with an electronic detector, repairs the leak when it is accessible, and then recharges to the manufacturer’s exact specification, measured by superheat and subcooling. Most AC recharge and leak-repair work runs $150 – $650 depending on the leak location and refrigerant type.
Low Charge Versus a Dirty Filter
Low airflow from a clogged filter can mimic the symptoms of low refrigerant. We check airflow first, and the filter is the first place we look. It costs nothing to check and can save you from a refrigerant service call that was never needed.
The Leak Must Be Found First
Adding refrigerant to a leaking system violates EPA rules and wastes your money. We use electronic leak detectors and, when necessary, a nitrogen pressure test to isolate the leak. You get the leak location in the written quote, not just a recharge and a handshake.
Emergency AC Repair
Emergency AC Repair is for the nights and weekends when your system fails completely and the indoor temperature climbs past safe levels. For our AC repair in Los Angeles, Dalton Heating & Air answers the phone with a live person 24 hours a day, 7 days a week. No voicemail queue, no callback window. A failed AC in extreme heat is a health risk for infants, elderly family members, and anyone with a heart or respiratory condition, so we treat these calls as a priority. Emergency repairs run the same $150 – $650 range as regular repairs. We do not charge an overtime rate or an after-hours surcharge, which is part of The Garrison Standard on every job.

What Counts as an Emergency
A total loss of cooling during a heat wave, a burning smell from the unit, or a breaker that trips repeatedly are emergency conditions. A slightly warm vent on a mild day is a scheduled call. Use the breaker box as a first check, then call us at (361) 306-9515 if the unit will not hold.
Same-Night Service, No Price Games
We keep emergency time slots open because a family should not have to sleep in a 90-degree house. The technician arrives with the truck stocked and the same written-price policy that applies at noon on a Tuesday. Urgency never changes the pricing process.
AC Not Blowing Cold Air
AC Not Blowing Cold Air is the most common symptom report we hear, and it has at least six possible causes ranging from a $20 filter to a failed compressor. You need a diagnostic when the system runs but the air is warm, the unit short-cycles, or the airflow is weak at every vent. Dalton Heating & Air tests the system in order of likelihood and cost: thermostat, filter and airflow, capacitor, refrigerant charge, condenser coil, and compressor. Most repairs land between $150 and $650. You will see the diagnostic finding on the written quote, and you will know the exact repair cost before we proceed.
Warm Air Is a Symptom, Not a Diagnosis
We do not guess and we do not quote a repair over the phone based on a description. The symptom tells us where to start looking, not what is broken. A technician has to measure voltage, pressures, and temperatures to find the actual failure. Anything else is a sales pitch.
Check the Filter Before You Call
A filter that is packed with dust will restrict airflow and cause the coil to ice over, which produces warm air at the vents. Turn the system off, pull the filter, and if you cannot see light through it, replace it. Then call us if the problem persists after a few hours of thaw time.
Brands We Service
Dalton Heating & Air is factory-trained to service all nine major residential HVAC brands. We work on Carrier systems daily, and our technicians know the specific capacitor ratings and control-board failure points that show up on Carrier condensing units and air handlers. Daikin and Bryant are also frequent calls. Daikin systems run their own inverter technology, and our diagnostic process for those units includes checking the communicating thermostat protocol. Bryant units share a lot of internal architecture with Carrier, but the part numbers differ, and we stock both lines.
American Standard is another brand we see regularly, particularly on the heat pump side. Compressor wiring, defrost board logic, and fan motor specs all vary by brand, and our technicians are trained on the correct testing procedure for each. Whether you have an American Standard, a Rheem, a Goodman, a Lennox, a Trane, a York, or any other make, we can diagnose and repair it. The parts sourcing and the factory service bulletins are what matter, and we keep both current.
Signs You Need a Pro Right Now
- Warm air at every vent while the system runs. This usually means the compressor is not doing its job or the refrigerant charge has dropped. Running the system in this state for weeks makes the eventual repair more expensive.
- Breaker trips repeatedly when the AC starts. A shorted compressor or a failed condenser fan motor can draw too many amps. Resetting the breaker repeatedly is a fire and shock risk, and high-tension electrical components inside the condensing unit should only be handled by a trained professional.
- Burning or acrid smell from the outdoor unit. That odor is often a failing fan motor or overheated wiring. Shut the system off at the thermostat and the breaker, and call us at (361) 306-9515 before running it again.
- Ice on the refrigerant line or the indoor coil. Ice usually means restricted airflow or low refrigerant. Running the system frozen can send liquid refrigerant back to the compressor and destroy it. Turn the system off and let it thaw while you wait for the technician.
- Loud grinding or screeching from the condenser. The fan motor bearings or the compressor internals are failing, and the noise is metal-on-metal contact. Every hour of run time in this condition brings you closer to a full compressor replacement instead of a smaller repair.
Our Process, Step by Step
- 1
Schedule the call. You call (361) 306-9515, a live person answers, and you get a real arrival window. No automated menu, no “we’ll call you back.”
- 2
Diagnostic with documentation. The technician tests the system in sequence: voltage, thermostat signal, capacitor microfarads, compressor amp draw, refrigerant pressures, and temperature differential. Every reading goes on the service ticket.
- 3
Written price before work starts. You get the problem, the fix, the part, the labor, and the total on paper. No work begins until you approve that number. This is the Written Price Before Any Work Starts policy, and it applies to every job without exception.
- 4
Repair and testing. Parts are replaced and the system is run through a full cycle to confirm the fix holds. We use digital manifold gauges for refrigerant work and a capacitance meter for every capacitor install.
- 5
Written guarantee and site cleanup. Every repair is covered by the 365-Day Done Right Promise, in writing. The site is left clean, the unit covers are back on, and the screws are not left on the pad. If the repair fails within the year, we return at no charge.
How Much Does AC Repair Cost?
Most AC repairs run $150 – $650 depending on the part that failed and the time involved. A typical AC capacitor replacement runs $150 – $350. A contactor swap usually falls in the $150 – $300 range. An AC recharge with leak search runs $250 – $650, depending on the leak location and the refrigerant type. A condenser fan motor replacement typically runs $350 – $650 with the part and labor combined. A full compressor replacement can run beyond that range and is often the point where replacement should be compared against repair. Tune-ups run $80 – $200 and can catch these failures before the hot season.
What affects the price is the part, the refrigerant, and the accessibility of the unit. A rooftop unit takes longer to service than a ground-level condenser. What you should never pay for is vagueness. A written quote that lists the part number and the labor removes the possibility of a door-shift price increase. A free estimate from us includes the full diagnostic, the written quote, and the guarantee. If you approve the repair, the price on that sheet is the price on the invoice. That is The Garrison Code, and it has been since 2003.
