Ocean Air Heating and Air Conditioning has served Manhattan Beach and the surrounding South Bay since 2005, handling residential and commercial heating, cooling, and air quality work for homeowners, landlords, property managers, and businesses. We find the fault. We make the repair. We restore the comfort. Call (424) 499-1692 for a quote.
Noticing uneven temperatures or a spike in energy bills? Those are usually the first signs that your HVAC system needs attention, and catching them early keeps repair costs manageable. We handle the full range of heating and cooling work: AC repair and service, heating and furnace repair, heat pump service, full system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality upgrades, and seasonal maintenance. Residential customers make up a large part of what we do, and we work with commercial clients, landlords, and property managers across the area as well. You get straight answers about your furnace, AC, and ductwork, no surprises, from the first call to the final walkthrough. Leave the heating and cooling to us.
When your air conditioner stops cooling, blows warm air, or cycles on and off without bringing the temperature down, the problem could be a refrigerant leak, a failing compressor, a dirty evaporator coil, or a condenser issue. A diagnostic visit gives you a clear picture of what is wrong and what it will cost to fix it. We walk you through the findings before any work begins.
A furnace blowing cold air or failing to start on a cool morning is not something to put off. We handle no-heat calls, gas furnace repair, ignition and heat exchanger issues, and airflow problems that leave some rooms cold while others stay warm. The goal on every repair visit is a system that heats evenly and reliably before we leave.
Heat pumps that stop heating in winter or stop cooling in summer usually need a refrigerant check, a component diagnosis, or a thorough tune-up. We handle heat pump repair, seasonal service, and full heat pump replacement when a system has reached the end of its useful life. If you are considering a new installation, heat pumps are a natural fit for the South Bay climate, and we will explain the options that make sense for your home or building.
When a repair no longer makes financial sense, a full system replacement puts you on solid ground for the next decade or more. We handle new AC installation, complete HVAC system replacement, and central air upgrades for homes and commercial properties alike. Work is performed by qualified HVAC technicians, and every installation meets California code requirements. Commercial system replacements follow the same standard, whether it is a small office or a larger retail or restaurant space.
Leaky or uninsulated ductwork is one of the most common reasons a system underperforms, and a duct inspection often reveals problems that explain high energy bills and uneven airflow. We repair, seal, and replace ductwork to bring the system back to full efficiency. On the controls side, a smart thermostat installation can make a real difference in comfort and energy use, and we handle setup and programming so the system runs the way you want it to. For air quality, we install whole-home air filtration systems, UV air purifiers, and upgraded filtration media that address dust, allergens, and airborne particles throughout the home.
If you are not sure your system can keep up, the coastal Southern California climate is worth understanding. Mild winters and warm summers define most of the year here, but recent heat events have pushed temperatures well beyond what older homes were designed to handle. Wildfire smoke season adds a separate air quality concern that has become a regular part of life in the South Bay. And across Los Angeles County, the shift toward all-electric equipment is accelerating. The services below reflect what we see most often in this area.
A large share of Manhattan Beach homes were built before central air conditioning was standard, and many were never wired or ducted for it. Ductless mini-split systems solve that problem directly. A mini-split installation involves mounting an indoor air handler in each zone you want to cool, connecting it to an outdoor compressor, and running a small conduit through the wall. No major construction, no new ductwork. The result is quiet, efficient, room-by-room cooling that works well in older bungalows, additions, and multi-unit buildings where running ducts is not practical. With heat events arriving more frequently along the coast, first-time cooling installations have become one of the most common calls we receive.
Smoke from regional wildfires does not stay outside. Fine particles move through standard filters and settle throughout the home, and the problem can persist for days after a fire event ends. We install MERV-13 and higher-rated filtration systems, whole-home air scrubbers, and UV purifiers that are designed to capture fine particulate matter and reduce airborne contaminants at the source. For South Bay residents, this has become a year-round concern rather than a seasonal one, and upgrading your filtration is one of the most practical steps you can take for the health of everyone in the building.
Los Angeles County has pushed hard on the transition away from gas-powered heating, and heat pump electrification is the most common path homeowners take when replacing an older gas furnace. A heat pump handles both heating and cooling in a single system, which simplifies equipment and reduces operating costs for most households. The installation involves removing the existing furnace, installing the new heat pump unit, and integrating it with your existing air distribution. We speak only to the HVAC equipment itself. Any circuit or panel work that the installation requires is handled separately by a qualified electrician.
Here is what most people get wrong about their HVAC system: waiting until a problem becomes an emergency almost always costs more than catching it early. That said, emergencies happen, and when your heat goes out in January or your AC fails during a heat event, you need a fast response. We take same-day calls and handle urgent repairs for both residential and commercial customers. Work is performed by qualified HVAC technicians who diagnose accurately and repair correctly the first time. We find the fault. We make the repair. We restore the comfort. Call (424) 499-1692 and we will get someone out to you.
A spring tune-up before cooling season and a fall check before the heater kicks on are the two most reliable ways to avoid mid-season breakdowns. A maintenance visit covers filter inspection and replacement, coil cleaning, refrigerant level check, airflow measurement, electrical connection inspection, and thermostat calibration. It takes a couple of hours and gives you a clear picture of where the system stands. Systems that are serviced regularly run more efficiently, last longer, and cost less to operate year over year. Call today and we will set up your appointment.
Property managers trust us to keep their buildings comfortable, and we understand what that means in practice: fast response, accurate diagnosis, and repairs that hold. We work with office buildings, retail spaces, restaurants, and multi-unit residential properties throughout the South Bay. Commercial system repair, replacement, and ongoing maintenance all fall within what we handle. Hire local and you get people who stand behind the work. Every commercial job we take on reflects that commitment, and code-compliant HVAC work on every job is a standard we hold to without exception.
HVAC repair costs, replacement costs, and installation costs vary based on equipment, scope, and what we find during the diagnostic visit. What does not vary is how we communicate with you. You get straight answers about your furnace, AC, and ductwork, no surprises, before any work begins. We explain what we found, what we recommend, and what it will cost. If the repair does not make sense compared to replacement, we will tell you that too. Call today and we will get the temperature back where it belongs.
We are based in Manhattan Beach and work throughout the surrounding communities every week. Our regular service area includes Hermosa Beach, Redondo Beach, El Segundo, Hawthorne, Lawndale, and Torrance, along with other neighborhoods across the South Bay. If you are in Los Angeles County and not sure whether we cover your area, give us a call and we will let you know.
We have been doing this work in Manhattan Beach since 2005, which means 21 years of local HVAC experience behind every job we take. When you call, you reach someone who knows the area and can talk through what you are dealing with. When we show up, it is the same people you spoke with, familiar with South Bay homes and buildings and accountable for the work they do. Not the biggest outfit in town. Just the most reliable. Always on time.
Yes. We work throughout the South Bay and cover Hermosa Beach, Redondo Beach, El Segundo, Hawthorne, Lawndale, Torrance, Gardena, and Inglewood regularly. If you are in Los Angeles County and are not sure whether we reach your area, call us at (424) 499-1692 and we will let you know right away.
We offer same-day service when the schedule allows, and we prioritize urgent no-heat and no-cool calls. For non-emergency work, lead times are typically short. Call (424) 499-1692 early in the day to give us the best chance of getting to you the same day.
A few basic details help us prepare: the type of system you have, the approximate age of the equipment, and a description of what it is doing or not doing. We will ask those questions when you call, and in most cases we can give you a clear picture of cost after the diagnostic visit.
In most cases, yes. We need access to the equipment and the opportunity to walk you through what we find before any work begins. If your schedule is tight, call us and we will work out an arrangement that fits.
We are available every day from 7:30 AM to 9:00 PM, which gives most homeowners and property managers a wide window to schedule around work or other commitments. Emergency calls are handled with urgency whenever they come in during our operating hours.
The age of the equipment, the cost of the repair relative to a replacement, and how often the system has been breaking down are the three factors we weigh together. If a repair no longer makes financial sense, we will tell you that plainly and walk you through the replacement options.
A pattern of repeated failures usually points to a system that has reached the end of its useful life. We will look at the repair history, assess the condition of the equipment, and give you an honest recommendation. Sometimes a targeted repair fixes the underlying cause; other times replacement is the right call, and we will say so.
We explain what we found and what the work will cost before anything is touched. If the scope changes once we are into the job, we stop and talk to you before going further. You will not see a number at the end that looks nothing like what we discussed at the start.
Every job we take on is held to California code requirements. Work is performed by qualified HVAC technicians who know what compliant installation and repair looks like in Los Angeles County. We do not cut corners on the work that protects the equipment and the people in the building.
System size, equipment type, and the scope of the work all affect the price more directly than square footage alone. A larger home with a bigger system or more complex ductwork will generally cost more to service or replace, but we size and price each job based on what we actually find.
Ocean Air Heating and Air Conditioning is Manhattan Beach's locally owned heating, cooling, and air quality contractor, ready to handle everything from an urgent repair to a full system replacement. Furnace fixed. AC humming. Home comfortable again. Call (424) 499-1692 for a quote and let us take it from there.

How do I know whether to repair my system or replace it?
We weigh three things together: the age of the equipment, the cost of the repair relative to what a replacement would run, and how often the system has been breaking down. If a repair no longer makes financial sense, we will tell you plainly and walk you through the replacement options. You will not be pushed toward a replacement when a repair is the right call.
Why has one room stopped cooling while the rest of the house feels fine?
Uneven temperatures usually point to a ductwork problem, a blockage, or a zone control issue rather than a failing unit. A dirty or partially blocked supply register, a duct leak near that room, or a failing damper can all cause the same symptom. A diagnostic visit gives us a clear picture of where the airflow is going and where it is not.
What does a seasonal maintenance visit actually cover?
A full tune-up includes filter inspection and replacement, coil cleaning, refrigerant level check, airflow measurement, electrical connection inspection, and thermostat calibration. It takes a couple of hours and gives you a clear picture of where the system stands heading into the next season. Systems that are serviced regularly run more efficiently and cost less to operate over time.
Transparent Upfront Pricing
We explain what we found and what the repair or installation will cost before any work begins. If the scope changes, we stop and talk to you first.
How quickly can you respond to a no-heat or no-cool emergency?
We offer same-day service when the schedule allows and prioritize urgent no-heat and no-cool calls. Calling early in the day gives us the best chance of reaching you the same day. We take emergency calls seriously because a system failure during a heat event or a cold overnight is not something that can wait.
What causes a system to short-cycle, meaning it turns on and off repeatedly without finishing a full run?
Short-cycling is usually caused by an oversized system, a refrigerant problem, a dirty evaporator coil, or a thermostat issue. It wastes energy, puts extra wear on the compressor, and rarely brings the temperature to where you want it. A diagnostic visit identifies the cause so the fix addresses the actual problem rather than the symptom.
How do duct leaks affect my energy bills?
Leaky or uninsulated ductwork lets conditioned air escape before it reaches the rooms you are trying to heat or cool. The system runs longer to compensate, which drives up energy costs and puts extra wear on the equipment. A duct inspection often explains why bills have been climbing even when the unit itself seems to be running fine.
Code-Compliant Work on Every Job
Every installation and repair we complete meets California code requirements. Work is performed by qualified HVAC technicians who know what compliant work looks like in Los Angeles County.
What strange noises from my HVAC unit should I take seriously?
Banging, grinding, or squealing usually point to a mechanical problem: a loose or failing blower motor, a worn belt, or debris in the unit. A rattling sound often means a panel or component has come loose. Clicking at startup that does not stop can indicate an ignition or relay issue. Any noise that is new or getting worse is worth a diagnostic visit before it turns into a larger repair.
How does a dirty filter or coil hurt system performance?
A clogged filter restricts airflow, which forces the system to work harder and can cause the evaporator coil to freeze. A dirty coil cannot transfer heat efficiently, which means the system runs longer and delivers less comfort. Both problems are avoidable with regular maintenance, and both can shorten the life of the equipment if left unaddressed.
Same-Day and Emergency Availability
We take urgent no-heat and no-cool calls seriously and offer same-day service when the schedule allows. Calling early in the day gives us the best chance of reaching you quickly.
What is involved in a smart thermostat upgrade?
We check that the new thermostat is compatible with your existing equipment, install it, and program it so it runs on a schedule that fits how you use the home. Most smart thermostats also give you remote control through a phone app. The whole process typically takes less than an hour, and we walk you through the settings before we leave.
Do I need to be home when the technician arrives?
In most cases, yes. We need access to the equipment and the opportunity to walk you through what we find before any work begins. If your schedule is tight, call us and we will work out an arrangement that fits.
Will the price change after the technician arrives?
We explain what we found and what the work will cost before anything is touched. If the scope changes once we are into the job, we stop and talk to you before going further. You will not see a number at the end that looks nothing like what we discussed at the start.
Every home and building is a little different, and the right solution depends on what we actually find when we look at your system. Call (424) 499-1692 and we will talk through what you are dealing with and get you a straight answer on what it will take to fix it.
