When your air conditioner quits in Los Angeles, you need a straight answer before the house heats up: what’s wrong, what it costs, and when someone can get there. Cold Harbour Heating and Air Los Angeles has been repairing AC systems across Los Angeles since 2003, and we answer the phone with a live person 24 hours a day, every day. Most homeowners want to know how much AC Repair costs, and in Los Angeles repairs typically run between $175 and $765 depending on what failed. Call (213) 531-5904 and you’ll get a real technician, not a voicemail tree, and a written price before any work begins.
Our home base is right here in the city, which means we get to your door fast when the thermometer climbs past 90 in the San Fernando Valley or the humidity settles in over West LA. Victor Mancini leads our team, and every repair we do carries the 365-Day Done Right Promise in writing: if that repair fails within a full year, we come back and make it right at no charge. No fine print. No arguments. That’s how we’ve operated for over two decades, and it’s why Los Angeles homeowners keep our number on the fridge.
AC Maintenance
AC Maintenance is the scheduled tune-up work that keeps your system running efficiently and catches small problems before they become hot-day breakdowns. In Los Angeles, where air conditioners often run from April through October, annual maintenance is the single best way to avoid a mid-August emergency. Cold Harbour Heating and Air Los Angeles performs a full maintenance visit for $95 to $235, which includes everything on our AC Repair Maintenance Checklist for Los Angeles Homeowners: cleaning the condenser coil, checking refrigerant levels, testing the capacitor, and inspecting electrical connections. A well-maintained AC in Los Angeles lasts longer and costs less to run each month, plain and simple.
What a Tune-Up Includes
Our technician checks every major component: condenser and evaporator coils, refrigerant pressure, blower motor, thermostat calibration, and drain line. We clean what needs cleaning and give you a written report showing exactly what we found, with photos when it helps. You’ll know the real condition of your system, not a vague list of “recommended services.”
When to Schedule It
Late spring works best for most Los Angeles homes, before the first heat wave forces your AC to work hard again. If you skipped maintenance last year, or you notice weak airflow or warmer air than usual, book a tune-up sooner rather than later. A $95 appointment in May beats a $765 repair in September.
Styles & brands we work with
AC Service
AC Service covers the full range of repair work, diagnostic visits, and adjustments that keep a Los Angeles cooling system functioning through the heat. When your system is short-cycling, making noise, or struggling to hold temperature, an AC service call is how you find out why. Cold Harbour Heating and Air Los Angeles charges $175 to $765 for typical AC service in this market, depending on what the technician finds after diagnosis. The diagnostic is always covered under that written quote you get before we open the toolbox, so there’s no surprise line item at the door.
Complete System Diagnostics
We test refrigerant pressures, electrical draws, thermostat signals, and airflow across the coil. A weak capacitor shows up on the meter in seconds. A clogged filter or a failing blower motor shows up in the airflow reading. You get a plain-English explanation of every finding before we recommend any repair.
Repairs on Every Major Brand
Our technicians train on nine major residential brands, so the guy who shows up for our AC Repair in Los Angeles already knows your Rheem, your Bryant, or your Daikin system. We stock common OEM parts in the truck and can get specialty parts same day from local Los Angeles supply houses most of the year. One visit, most of the time.
AC Unit Repair
AC Unit Repair is the hands-on work of fixing a specific failed component inside your air conditioning system, whether it’s the compressor contactor, the blower motor, the control board, or a refrigerant leak. In Los Angeles, AC unit repair costs between $175 and $765 for the vast majority of residential jobs, parts and labor included. Cold Harbour Heating and Air Los Angeles writes the repair quote down and hands it to you before touching a single screw, which means the price you approve is the price you pay. If that repair fails inside 365 days, we return free and fix it.
Common Repairs We Make in Los Angeles
Capacitors, contactors, fan motors, thermostats, drain line clogs, and refrigerant leaks are the everyday calls we run across Los Angeles, from South Gate up through Santa Monica. Each one has a known parts cost and a predictable labor window, which lets us price accurately instead of guessing. A $45 part installed wrong is a $600 repair later, so we do it right the first time and then put that promise in writing.
After the Repair
We test the full system cycle before we leave: startup, run, shutoff, thermostat accuracy. Then we clean the work area and hand you the written guarantee. You’ll know what was replaced, what it cost, and exactly how long the repair is covered.
AC Capacitor Replacement
AC Capacitor Replacement is one of the most common AC repairs we perform in Los Angeles, and it’s usually the fix when your outside unit hums but won’t start, or starts and stops repeatedly. The capacitor is the small cylindrical component that gives the compressor and fan motor the electrical jolt they need to spin up. When it fails, the system simply won’t cool. Cold Harbour Heating and Air Los Angeles replaces capacitors for roughly $175 to $350 in most cases, parts and labor included, and the work is covered by the 365-Day Done Right Promise.
Warning Signs of a Failing Capacitor
A capacitor usually fails slowly: the AC takes longer to start, the outdoor fan doesn’t spin right away, or you hear a clicking sound from the unit. If the system won’t start at all but the indoor blower is running, that’s the classic capacitor symptom. Catching it early saves wear on the compressor, which is the most expensive component in the system.
How We Test and Replace It
Our technician uses a meter to read the capacitor’s microfarad rating, compares it to the manufacturer’s spec printed on the side, and replaces it if it’s out of range. The swap typically takes under an hour. We use OEM or equivalent capacitors rated for the actual system, not the cheapest generic on the shelf.
AC Recharge
AC Recharge means restoring the correct amount of refrigerant, the cooling fluid your AC needs to absorb heat from inside your Los Angeles home and release it outside. A system that’s low on refrigerant can’t cool properly because there isn’t enough fluid cycling through the coil to move the heat. Cold Harbour Heating and Air Los Angeles performs AC recharge service for $175 to $765 depending on how much refrigerant needs to be added and whether we need to find and repair a leak first. Refrigerant doesn’t get “used up” like gas in a car, so a low charge always means a leak, and we find and fix that leak before refilling.
Signs Your AC Needs a Recharge
Warm air from the vents, ice on the refrigerant lines, longer run times, and rising electric bills in Los Angeles summer months all point to low refrigerant. If you see frost on the copper line going into the indoor unit, that’s a direct visual cue. The system is running too cold at the coil because there isn’t enough refrigerant to absorb heat efficiently.
What We Check During a Recharge
We locate the leak with an electronic leak detector or UV dye, repair it, then weigh in the exact refrigerant charge your system’s nameplate calls for. Charging by weight, not by feel, is the difference between a system that cools properly and one that floods or starves the coil. After the recharge, we measure the temperature drop across the coil to confirm the numbers are right.
Emergency AC Repair
Emergency AC Repair is what we do when your Los Angeles home is heating up on a 95-degree Saturday and you can’t wait until Monday. Cold Harbour Heating and Air Los Angeles answers the phone with a live person 24 hours a day, 7 days a week, including holidays. Emergency calls in Los Angeles typically cost between $175 and $765 for the repair itself, and we do not charge an overtime penalty just because it’s the weekend or the middle of the night. You get the same written price and the same 365-Day Done Right Promise, whether we arrive at noon or 3 a.m.
What Counts as an Emergency
No cooling at all when someone in the house is elderly, ill, pregnant, or very young makes it a health matter, not a comfort preference. A burning smell or smoke from the unit is an emergency, period. If the AC is running but the house won’t cool below 85, that’s urgent enough to call, because the problem won’t fix itself and the heat load in Los Angeles builds fast.
Our Response in Los Angeles
We aim to get a technician to your door within a few hours in Los Angeles proper, Burbank, Glendale, Culver City, and the surrounding communities. A live person takes the call, a real technician calls you back with a more specific arrival window, and the truck rolls with common repair parts already loaded. The written quote comes before the work, no matter what time it is.
AC Not Blowing Cold Air
AC Not Blowing Cold Air is the most common call we get in Los Angeles from June through September, and the cause is usually one of five or six specific failures, not a mystery. It might be a dead capacitor, low refrigerant, a frozen coil, a clogged filter, or a failed compressor contactor. Cold Harbour Heating and Air Los Angeles diagnoses the exact cause on the first visit, writes the repair price down, and gets your cool air back for $175 to $765 in most Los Angeles homes. The full diagnosis is included in the free estimate, so you never pay to find out what’s wrong.
What to Check Before You Call
Look at the thermostat: is it set to “cool” and below room temperature? Change the air filter if it’s visibly dirty, because a clogged filter restricts airflow and can freeze the coil, which makes the system blow warm. Make sure the outdoor unit isn’t covered in leaves, cottonwood, or Santa Ana dust. If those three things look fine and the air is still warm, the problem is mechanical and a technician needs to see it.
How We Diagnose It Fast
Our technician starts with the thermostat, moves to the air handler, then checks the outdoor condenser, tracing the electrical and refrigerant circuits in order. The sequence tells us the story: if the compressor is running but the lines aren’t cold, it’s a refrigerant issue. If nothing outside is running, it’s electrical. You’ll watch us work through it, and we’ll explain what we find in plain English before we quote the fix.
Brands We Service
Cold Harbour Heating and Air Los Angeles technicians are trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We work on Rheem systems regularly in Los Angeles, and our techs know the common failure points on Rheem condensing units, from contactor wear to fan motor failures. A Rheem compressor contactor is a stock part on our trucks, so that repair often happens in one visit.
York and Daikin systems also show up often in Los Angeles homes, especially newer construction and recent retrofits in neighborhoods like Culver City and West Hollywood. York’s current line uses inverter-drive compressors that require specific diagnostic procedures, and Daikin mini-splits have their own control board logic. When a Bryant system rolls up on the schedule, the technician already knows the unit before pulling into the driveway, because we pull make and model at the time of booking. Whether you have one of these brands or something else entirely, we can help. If it cools air in Los Angeles, we fix it.

AfterSigns You Need a Pro Right Now
- The air blowing from the vents is warm or room temperature. This means the compressor isn’t cooling the refrigerant, the refrigerant is gone, or the system has lost its charge. In Los Angeles summer heat, a warm vent means your indoor temperature will climb steadily until the system is fixed.
- The outdoor unit runs but the indoor blower doesn’t. That points to a failed blower motor, a capacitor, or a control board issue. The compressor is working, but without airflow across the coil, you get no cooling and the coil can ice over.
- You hear grinding, squealing, or banging from either unit. Mechanical noise means a bearing is failing, a fan blade is hitting something, or a motor is on its way out. Running it in that condition turns a small repair into a major one.
- The AC short-cycles: it starts, runs a few minutes, then shuts off. That pattern is often a failing capacitor, a refrigerant overcharge, or a compressor overheating. Short cycling drives your electric bill up and shortens the life of the compressor.
- Water is pooling around the indoor unit or dripping from the ceiling. A clogged condensate drain or a frozen coil that’s thawing is the culprit. Water damage in a Los Angeles home gets expensive fast, so shut the system off and call before it spreads.
Our Process, Step by Step
- 1
You call (213) 531-5904. A live person answers, day or night. We take your address, the make of your system if you know it, and what the AC is doing or not doing. Then we give you a firm arrival window, not a vague “sometime tomorrow.”
- 2
The technician arrives and sees the system first. Uniformed, background-checked, and carrying a meter, gauges, and common OEM parts for Rheem, York, Bryant, Daikin, and the other major brands. We don’t open the truck until we’ve looked at the unit and listened to what you’ve noticed.
- 3
We diagnose and write the price down. The diagnostic is free, and the repair quote is itemized: parts, labor, everything. You see the number before we touch a tool. If the repair isn’t worth doing, we tell you that too, and we’ll show you why.
- 4
We fix it and test it. The repair happens, then we run a full cycle: startup, run, shutoff, thermostat response. We measure the temperature drop across the coil to confirm the numbers are right, not just that the unit turns on.
- 5
We hand you the written guarantee and clean up. Every repair gets the 365-Day Done Right Promise in writing. We clean the work area before we leave, so the only thing different from when we arrived is that the house is cool again.
How Much Does AC Repair Cost in Los Angeles?
A typical AC repair in Los Angeles runs between $175 and $765, with most common fixes landing in the $250 to $450 range. A capacitor replacement usually runs $175 to $350. A refrigerant recharge, including finding and fixing the leak, typically runs $300 to $765 depending on the leak’s location and how much refrigerant needs to be added. A failed blower motor runs $350 to $650 with parts and labor. These are the real numbers we quote in this market every week, from Florence-Graham up through AC Repair in Huntington Park and across to Santa Monica.
What moves the price is the part, the system’s age, and access. A compressor contactor for a Rheem is cheaper than a variable-speed blower motor for a newer Carrier. Attic installations in older Los Angeles homes take longer than closet installations in newer builds. The best way to avoid overpaying is to get the written price before work begins, which is how we operate on every job. Our estimates are free, no work happens without your written approval, and you’ll never find a new line item added at the door. If a company won’t put the number in writing, that’s your signal to get a second opinion.
