San Bernardino HVAC Company handles heating and cooling work for homes, rental properties, and commercial spaces across San Bernardino and the surrounding Inland Empire. Whether your AC stopped working in the middle of a 105-degree afternoon, your furnace won't turn on, or your system is down and you need someone on the phone who can scope the job, we are available every day from 5:30 AM to 8:30 PM.
Call (760) 915-1995 to get started.
We pick up the phone. We scope the job. We book the visit.
Before anything bigger gets suggested, we check filters and airflow first. A clogged filter or a restricted return can mimic a failing compressor, and there is no reason to quote a major repair until the simple stuff is ruled out.
Comfort problems don't wait, and neither do we. Whether it is a central air system blowing warm air, a furnace pushing out cold air, a heat pump that has stopped responding, or a system that simply will not turn on, we handle the full range of residential and commercial heating and cooling repair. That covers everything from a single-family home in a San Bernardino neighborhood to an apartment complex, a retail space, or a commercial building anywhere in the county.
When a house will not cool down evenly, we do not assume the equipment is failing. The cause of an uneven house is actually investigated: duct condition, refrigerant charge, airflow balance, and thermostat calibration all play a role, and we work through them in order. One call gets the whole thing moving.
When an air conditioner stops cooling, the diagnosis starts with the basics and works outward. We check the refrigerant charge, inspect the evaporator coil and condenser coil, and test the blower and air handler before drawing any conclusions. A system blowing warm air might have a refrigerant leak, a frozen evaporator coil, or a condenser issue. A unit that will not turn on at all might be a thermostat, a capacitor, or something in the control board.
We cover central AC repair, condenser and compressor service, and evaporator coil cleaning and repair. If the coil is dirty enough to restrict airflow, cleaning it is often the fix before any part gets ordered. The goal is a correct diagnosis, not a fast parts swap.
Whether this is your first HVAC repair or your tenth, the diagnostic visit works the same way. We look at what the system is doing, check the heat exchanger, test the igniter and flame sensor, and go through the air handler and blower before naming a repair. A furnace blowing cold air, a furnace that will not turn on, or a system that cycles on and off without heating the house all point to different causes, and each one gets traced to its source.
Heat pump repair follows the same approach. A heat pump that is not producing heat in winter or cooling in summer often has a reversing valve issue, a refrigerant problem, or a defrost cycle fault, and sorting out which one requires a proper look at the system. We'll get your comfort back on track.
At some point, repair stops making sense. An older system that needs a major component replaced, a unit that has been losing efficiency for years, or ductwork that cannot support the existing equipment are all situations where replacement is the more practical path. We handle full HVAC system replacement and new installation: central AC units, furnaces, heat pumps, and mini-split and ductless systems for spaces without existing ductwork.
The decision between repair and replacement is one we work through with you on the call. Right diagnosis. Right repair. Right parts for your system.
When a new system goes in, sizing matters. An oversized unit short-cycles and leaves the house humid and uncomfortable. An undersized one runs constantly and never catches up. We size the equipment to the space before anything is ordered.
From a quick tune-up to a whole-system replacement, the diagnosis comes first, and that often means looking at the duct system. Leaking or poorly sealed ductwork is one of the most common causes of uneven temperatures and higher energy bills, and it often goes undiagnosed for years. We handle duct sealing, duct repair, and full ductwork replacement when the system calls for it. Ductwork is checked when the symptoms point that way, not assumed to be fine.
Thermostats are a smaller job that makes a real difference. A thermostat that is reading the wrong temperature, cycling the system at the wrong times, or simply failing to communicate with the equipment can make a perfectly good HVAC system perform badly. We install smart thermostats and standard replacements, and we handle zoning and comfort-control systems for homes that need different temperatures in different areas.
On the air quality side, we install whole-home air filtration systems and air purifiers that connect directly to the HVAC system. A portable filter handles one room. A whole-home unit handles every room the ductwork reaches.
A maintenance visit covers the full system: filter and airflow check, coil condition, thermostat calibration, refrigerant level, and a general inspection of the components that tend to fail first. In San Bernardino, the spring tune-up before cooling season is the one most people prioritize, and for good reason. Running a system hard through a long, hot summer without a pre-season check is how small problems become expensive ones in August.
Fall maintenance matters too. Even though San Bernardino winters are mild, a furnace or heat pump that has not been looked at since the previous heating season can surprise you on the first cold night. We schedule maintenance calls the same way as repair calls. We'll take the details and get it scheduled.
When the system goes down and the house is heating up or cooling off fast, the priority is getting someone on the phone who can help. We take emergency calls every day from 5:30 AM to 8:30 PM. No cool air, no heat, a system that shut off overnight, a furnace that stopped working before a cold snap: these are the calls we are set up to handle.
We pick up the phone. We scope the job. We book the visit.
We do not promise an arrival window on this page because we confirm what the schedule allows when you call. What we can tell you is that emergency calls are answered, and the person who picks up knows enough about the equipment to start troubleshooting before anyone shows up.
San Bernardino sits in the Inland Empire, where summer heat regularly pushes past 100 degrees and the air stays dry enough for evaporative cooling to work well through most of the season. Winters are mild by most standards, but a stretch of cold nights is enough to remind you that the heating system needs to function. That climate mix shapes the HVAC work that comes up most often here, and three services in particular reflect it.
An evaporative cooler pulls outside air through water-saturated pads and drops the temperature through evaporation. In dry heat, it works efficiently and costs less to run than refrigerated air. San Bernardino's low humidity through most of the summer is exactly the condition where evaporative cooling performs well, which is why swamp coolers are still common in the area.
A service visit covers pad replacement, pump inspection, water distribution lines, and a check of the blower and belt. A swamp cooler blowing warm air usually points to worn pads, a pump that is not moving water, or a clogged distribution system, and most of those are straightforward fixes once the unit is opened up.
As summer temperatures push higher and monsoon moisture occasionally moves into the Inland Empire, a swamp cooler can stop keeping up. High humidity shuts down evaporative cooling almost entirely, and a stretch of 110-degree days will overwhelm an older unit even in dry air. At that point, conversion to refrigerated central air becomes the practical answer.
The conversion involves removing the evaporative unit, installing a refrigerated central air system, and connecting it to existing ductwork or running new ductwork where needed. It is a significant job, and we walk through what it involves on the call before anything is scheduled.
A heat pump handles both heating and cooling from a single system, which suits San Bernardino's climate well. Mild winters mean the heating load is low, and a heat pump handles that load efficiently. Hot summers are where the cooling side earns its keep.
Installation involves equipment sizing, placement of the outdoor unit, and connection to existing ductwork or a ductless configuration for spaces where ductwork is not practical. Mini-split systems are a good fit for additions, converted garages, or any room that the main duct system does not reach well. One call gets the whole thing moving.
Homeowners, landlords, property managers, and business owners all call us for the same core reason: something stopped working, or they want to stay ahead of a system that is getting older. We handle single-family homes, multi-unit rental properties, apartment buildings, and small commercial spaces throughout San Bernardino and the county.
A property manager dealing with a tenant complaint about a broken AC in July needs a fast answer and a clear process. A homeowner who has never called an HVAC company before needs someone who will explain what the visit covers before it is scheduled. We handle both. Doing it properly the first time is the whole point.
When the job is done, we leave your home clean and comfortable, but the conversation about price happens before anyone shows up. You get the rate on the phone. The price is confirmed before we schedule, and you are told what the visit covers. If the diagnostic points to a repair, the cost of that repair is explained before any work starts.
HVAC repair costs vary by system type, what needs to be replaced, and how long the job takes. We do not quote a number before we know what we are dealing with, but we do give you a clear picture of the diagnostic visit cost and what it includes before we book it. That is the starting point for every repair call.
To schedule a maintenance visit, a repair call, or a quote on a new system, call (760) 915-1995. We are available every day from 5:30 AM to 8:30 PM.
We serve San Bernardino and the communities around it throughout San Bernardino County, including Fontana, Rialto, Colton, Redlands, Highland, Loma Linda, Grand Terrace, and Bloomington. If you are in the Inland Empire and need heating or cooling work, call to confirm we cover your address.
The outdoor unit inspection covers the condenser coil condition, refrigerant line connections, fan motor operation, and the electrical connections at the unit itself. On a heat pump, the reversing valve and defrost cycle are also checked, since those are common failure points when a heat pump stops heating or cooling correctly. Coil blockage from dust, debris, or plant growth is one of the more common outdoor unit problems in the Inland Empire's dry, windy climate, and it gets looked at early in the diagnostic. A system that is running but not cooling efficiently often traces back to a partially blocked condenser coil.
A banging or clanking sound from the air handler or furnace often points to a loose blower wheel, a failing motor mount, or debris inside the unit. A squealing sound usually comes from a belt or bearing that is wearing out. Rattling can indicate loose panels, debris in the ductwork, or a component that has come loose inside the unit. None of these should be ignored: a noise that starts small often gets worse quickly, and catching it early usually means a smaller repair.
A system that runs continuously without bringing the temperature down is one of the more common cooling calls in San Bernardino. The most frequent causes are a low refrigerant charge, a dirty or blocked evaporator coil, a condenser coil that cannot reject heat properly, or an airflow restriction through the air handler. An oversized system that short-cycles can also leave the house feeling warm and humid even when the thermostat reads correctly. The diagnostic visit works through each of these in order rather than assuming the most expensive cause first.
The diagnostic starts with the symptoms described on the call and works outward from there. The technician checks the filter and airflow first, then inspects the equipment components most likely to cause the reported symptom: refrigerant circuit, coil condition, electrical connections, and control board or thermostat communication. The goal is to find the actual cause rather than replace parts until the problem goes away. Once the cause is identified, the repair and its cost are explained before any work starts.
Turn the system off at the thermostat to avoid running equipment in a fault condition. If the house is heating up because the AC is down, close blinds and curtains on sun-facing windows to slow the heat gain. If the heat is out on a cold night, keep interior doors closed to retain warmth in the rooms you are using. Do not attempt to open the unit or reset components repeatedly, as that can make diagnosis harder when the technician arrives.
The scope is determined by what the diagnostic finds, not by a standard service package. After checking the system, the technician explains what was found, what caused it, and what the repair involves. If more than one issue is present, those are prioritized by what is affecting performance now versus what is worth monitoring. The scope and the cost are confirmed before any work begins.
Yes. An older thermostat that is not compatible with a current system can cause short-cycling, incorrect temperature readings, or a failure to communicate with the equipment at all. This comes up most often when a new system is installed but the existing thermostat is left in place. We check thermostat compatibility as part of the diagnostic when the symptoms point that way, and we install programmable and smart thermostats that are confirmed to work with the equipment before the visit ends.
A swamp cooler service visit covers pad inspection and replacement, pump operation and water flow, the distribution lines that carry water across the pads, and the blower and belt condition. A cooler that is running but not dropping the temperature the way it should is usually a pad, pump, or airflow problem, and those are checked in order. Seasonal startup and shutdown visits follow the same process and are a practical way to catch worn components before the cooling season begins.
The conversion starts with removing the existing evaporative unit and assessing the ductwork for compatibility with a refrigerated system. If the existing ducts can support the new equipment, the installation connects to them. If the ductwork needs modification or replacement, that is part of the scope. Equipment sizing for the home is confirmed before anything is ordered, since an incorrectly sized system will not perform well regardless of how well it is installed.
Leaking ducts allow conditioned air to escape into attics, crawl spaces, and wall cavities before it reaches the rooms it was meant for. The result is uneven temperatures, a system that runs longer than it should, and higher energy bills. Duct sealing closes the gaps and connections where air is escaping, which lets the system deliver its full output to the living space. We inspect ductwork when the symptoms point that way, including uneven room temperatures and registers with noticeably weak airflow.
Extremely high temperatures can affect how refrigerant systems behave during testing, and the technician accounts for ambient conditions when taking pressure readings and checking system performance. Installation work on outdoor units is generally not affected by dry heat, but the technician will note conditions that could affect the accuracy of a diagnostic reading. In San Bernardino's climate, the bigger factor is often the heat load on the equipment during the visit itself, which is why outdoor unit work is noted in the job scope when you call.
A system that is losing efficiency, whether from a low refrigerant charge, dirty coils, a failing compressor, or duct leaks, has to run longer to move the same amount of heat or cool air. Longer run times mean more energy consumed for the same result. In San Bernardino's long cooling season, a system that is slightly underperforming can add meaningfully to a summer energy bill before the problem is obvious enough to prompt a service call. A pre-season tune-up catches those efficiency losses before they compound.
For most repair and diagnostic work, the technician controls power to the equipment at the unit itself using the disconnect or the system controls. You do not need to shut off the main panel before the visit. If the job requires the power to be off at a specific point, the technician will let you know what is needed before starting. The scope of the visit is explained on the call so there are no gaps in what to expect.
San Bernardino HVAC Company handles the full range of heating and cooling work: repair, replacement, installation, maintenance, and emergency service. Whether the AC just stopped working, the furnace is not producing heat, or you are ready to replace an aging system, we are available every day from 5:30 AM to 8:30 PM.

How do I know whether to repair or replace my HVAC system?
The decision comes down to a few practical factors: how old the system is, what the repair costs relative to replacement, and whether the equipment can still meet the demand of the space. A system that needs a major component replaced, such as a compressor or heat exchanger, often makes more financial sense to replace than to repair, especially if it has been losing efficiency over time. We work through the repair-versus-replace question with you on the call once the diagnostic is done, so the decision is based on what we actually found rather than a general rule.
What are the signs that my AC or furnace might need to be replaced soon?
A system that is struggling to reach the set temperature, cycling on and off more frequently than it used to, or producing noticeably higher energy bills without a change in use is showing signs of declining efficiency. Frequent repairs over a short period are another signal, particularly when the cost of each repair is climbing. Age matters too. A system that is well past its expected service life and starting to need major work is usually a better candidate for replacement than continued repair.
What causes a system to short-cycle, and why does it matter?
Short-cycling is when a system turns on, runs briefly, and shuts off before completing a full heating or cooling cycle. It can be caused by an oversized system, a refrigerant issue, a failing thermostat, a dirty evaporator coil, or a problem with the control board. It matters because a system that short-cycles never runs long enough to properly dehumidify or condition the air, and the repeated start-stop puts extra wear on the compressor and other components. We check for short-cycling as part of the diagnostic when the symptoms point that way.
System Checked Before Parts Are Quoted
We work through the diagnostic before recommending a repair. Filter and airflow are checked first, and the cause of the problem is identified before any part or replacement is suggested.
How often should HVAC maintenance be scheduled?
Most systems benefit from a check before each major season: a cooling-season tune-up in spring and a heating-season check in fall. In San Bernardino, the spring visit before summer is the one most homeowners prioritize, since the cooling season is long and the system runs hard from late spring through early fall. Fall maintenance is worth doing even with mild winters, because a furnace or heat pump that has not been inspected since the previous season can develop problems that only show up when the system is needed.
What are the signs of a refrigerant problem?
A system with a low refrigerant charge typically struggles to cool the space even when running continuously, may ice up on the evaporator coil, or produces airflow that is less cold than it should be. You might also notice the system running longer than usual without reaching the set temperature. A refrigerant problem is not a maintenance item that gets topped off on a schedule. It points to a leak somewhere in the system, and finding and repairing the leak is part of the job before refrigerant is added.
Why is one room in my house hotter or colder than the rest?
Uneven temperatures usually come from one of a few sources: a duct that is leaking, disconnected, or undersized for the room it serves, a damper that is closed or stuck, an airflow imbalance in the system, or equipment that is not sized correctly for the home. We investigate the actual cause rather than assuming the equipment is failing. Ductwork condition, airflow balance, and thermostat calibration are all checked when a house is cooling or heating unevenly, because the fix depends on what is actually causing the problem.
Emergency No-Heat and No-Cool Calls Handled
When the system goes down, we take the call and start troubleshooting on the phone. Emergency service is available every day from 5:30 AM to 8:30 PM.
How does a dirty filter or coil affect system performance?
A clogged filter restricts the airflow the system needs to move heat or cool air through the home. When airflow drops, the evaporator coil can ice over, the blower motor works harder than it should, and the system loses efficiency. A dirty evaporator or condenser coil has the same effect: it reduces the surface area available for heat transfer, which means the system runs longer and works harder to produce the same result. We check filters and airflow before suggesting bigger repairs, because a restriction can mimic symptoms that look like a failing compressor or refrigerant problem.
What does a thermostat or smart-control upgrade actually involve?
The upgrade starts with confirming that the new thermostat is compatible with the existing equipment, since not all smart thermostats work with every system configuration. Once compatibility is confirmed, the old unit is removed, the new one is wired in, and the system is tested to make sure the thermostat is communicating correctly with the equipment. Programming and scheduling features are set up before the visit ends. For homes with zoning systems, the process also covers the zone controllers and damper operation.
Older Systems and New Installs Both Covered
Whether the equipment is decades old or was installed last year, we handle the diagnostic and the repair the same way: find the actual cause, explain the fix, and confirm the cost before work starts.
Is it worth repairing an older HVAC system, or is replacement always the better option?
Older equipment is not automatically a candidate for replacement. A system that is functioning well but has a specific failed component, such as a capacitor, a contactor, or a motor, can often be repaired cost-effectively. The calculation changes when the repair cost approaches a meaningful percentage of replacement cost, when the same system has needed multiple repairs in a short period, or when the equipment is old enough that parts are becoming difficult to source. We give you a straight answer on that question after the diagnostic, based on what the system actually needs.
What should I know about how emergency HVAC calls are handled?
When you call with a system that is completely down, the person who answers can begin working through the problem with you on the phone. That conversation covers what the system was doing before it stopped, what the thermostat is reading, and whether there are any obvious signs of a fault. From there, we confirm what the schedule allows and book the visit. We take emergency calls every day from 5:30 AM to 8:30 PM. The scope and the visit cost are explained before anyone is dispatched.
What does a whole-home air filtration installation involve?
A whole-home air filtration system connects directly to the existing HVAC ductwork, so it treats the air moving through every room the ducts reach rather than just the room where a portable unit sits. The installation involves selecting a unit sized for the system's airflow, cutting in the filter housing at the appropriate point in the duct run, and confirming that the addition does not restrict airflow enough to affect system performance. We check filter sizing and system compatibility before anything is ordered.
