When a system stops working in Alamo, the call needs to go somewhere that can scope the problem before anyone shows up. We handle the full range of residential heating and cooling work: AC repair and service, furnace and heat pump repair, ductless mini-split installation, ductwork repair and sealing, thermostat upgrades, indoor air quality, and full system replacement. Every call gets the same attention, whatever the job size. Call for a quote and we will go through what the visit covers before anything is scheduled.
Alamo's housing stock runs toward larger single-family homes, many of them built before ductless cooling was a common option and some still running on equipment that has been in place for a long time. We also work with landlords and property managers who need a system brought back into service without a long delay. Whatever the property and whatever the system, the diagnosis starts on the call and the price is confirmed before we book.
A thermostat set to "fan only" instead of "cool" or "heat" will run the blower without conditioning the air, and it is one of the most common reasons a system seems to be running but not doing anything. Check the mode first. While you are there, check the filter. A filter that is packed with dust restricts airflow enough to cause a system to overheat, shut down on a safety limit, or cool unevenly across the house. If it is visibly gray and dense, swap it before calling.
HVAC equipment usually has a dedicated power switch nearby that looks like a light switch. It gets bumped off occasionally, especially in utility rooms where other work has been done. Check that it is on. If the outdoor unit is not running but the air handler is, the outdoor unit may have tripped its own disconnect. That is worth a look before concluding the system has failed. If the breaker has tripped and trips again when you reset it, stop there and call. A breaker that keeps tripping is pointing at something that needs a proper diagnosis.
The price for any HVAC job depends on what the system actually needs, and that is not always clear until someone has looked at it. A diagnostic visit establishes the cause. From there, what moves the quote is the nature of the fault, what has to be accessed to fix it, and whether repair or replacement is the honest answer given the age and condition of the equipment.
Repair and replacement land in very different places, and the gap between them is not always as wide as it looks. An older system that needs a major component may cost nearly as much to repair as a new unit would to install, and a new unit comes with a full equipment life ahead of it. We give honest recommendations on repair versus replacement, never an upsell. The goal is the right answer for your situation, not the more expensive one.
When you call, we go through the scope, confirm the price, and explain what the visit covers. No-pressure estimates, priced up front.
Call (650) 899-6391 and we will tell you what to expect before anything is booked.
A system that is low on refrigerant does not just cool less. It runs longer, struggles to reach the set temperature, and eventually starts damaging the compressor. Low refrigerant is almost always a leak rather than normal depletion, so adding refrigerant without finding the source is a temporary fix. We trace the leak, repair it, and recharge the system to the correct level.
A system that runs for hours without bringing the space to temperature is working harder than it should and costing more to run. The cause could be a refrigerant issue, a dirty evaporator coil restricting heat transfer, a duct run that is losing conditioned air before it reaches the room, or equipment that was never sized correctly for the space. Airflow and uneven-temperature troubleshooting starts with the symptom and works back to the cause rather than replacing parts until something works.
A banging sound at startup usually points to something loose in the blower assembly. A grinding or screeching noise from the outdoor unit often means a bearing is failing. A rattling that comes and goes with airflow is frequently a duct panel or a loose register. None of these fix themselves, and most get worse if the system keeps running. Describing the noise on the call helps narrow down what needs to be checked.
Leaking ducts are a common reason a home heats or cools unevenly, and they are easy to miss because the problem is hidden inside walls, ceilings, and crawl spaces. Conditioned air that escapes into an unconditioned space never reaches the rooms it was meant to serve. We inspect duct runs, seal leaks, and replace sections that are too far gone to patch. For homes where additions were never properly connected to the original duct system, ductwork repair can make a bigger difference than any equipment upgrade.
Older equipment brings its own set of considerations. Parts for systems that are no longer in production can be hard to source, and a repair that would be straightforward on current equipment may take longer or require a substitution. That is worth knowing before the visit, not after.
Ducting is often the more significant issue in older Alamo homes. Duct systems that were sized for the original floorplan may not serve rooms that were added later. Flex duct that has sagged or kinked over the years loses a significant amount of its capacity. These are not problems that show up on an equipment inspection because they live in the distribution side of the system, not the mechanical side.
We treat your home and its system the way we would our own. When an older system is the subject of the call, we go through the full picture on the visit: what the equipment needs, what the ductwork looks like, and whether a repair extends a useful life or delays a replacement by a short time. That conversation happens before any work is quoted, not after.
A home with no heating on a cold night or no cooling during a heat event is a situation that cannot wait for a regular appointment slot. We are available every day from 7 AM to 8 PM, including weekends, and emergency no-heat and no-cool calls are taken within those hours. The call is answered by someone who knows the trade and can scope the problem on the phone. That scoping happens before anyone is dispatched, so the visit is not a first look at the situation.
For landlords and property managers, a system that goes down in an occupied property needs to move quickly. We work around tenants and occupied buildings, confirm access details during scheduling, and flag anything that needs to be arranged ahead of the visit. If the property needs to stay open and operational during the work, let us know on the call and we will go through what that requires.

A property with no cooling during a heat event is the kind of situation we treat as urgent. Call and describe the situation and we will go through what is available. We are reachable every day from 7 AM to 8 PM.
At a minimum, once a year for a system that handles only one season, and twice a year for a heat pump or year-round system. A spring check before the cooling season and a fall check before the heating season are the standard intervals. Regular maintenance catches small problems before they become the reason a system fails during peak demand.
Yes. Once the cause of a problem is identified, the technician will explain what led to it and what, if anything, can be done to reduce the likelihood of it recurring. That might be a maintenance interval, a filter change schedule, or a setting adjustment. The goal is for the visit to leave you better informed, not just with the immediate problem resolved.
A system that has stopped working entirely during extreme heat or cold, a smell of burning from the equipment, or a situation where the property is unsafe to occupy due to temperature are the clearest examples. We handle urgent calls every day from 7 AM to 8 PM. If you are unsure whether your situation qualifies, call and describe it.
We are available every day from 7 AM to 8 PM. If a commercial replacement needs to happen outside peak business hours to minimize disruption, call and we will discuss what the schedule allows. What is possible depends on the scope of the job and the timing of the request.
They are often the most practical option. A ductless system does not require existing ductwork, which makes it well suited to homes where adding ducts would mean significant construction. Each indoor unit mounts on the wall and connects to an outdoor compressor through a small conduit. For homes with one or two rooms that need cooling added, a single-zone mini-split handles the job without touching the rest of the house.
The call covers the system type, what it is doing, and the access situation at the property. We confirm the scope and price on the call before scheduling, and we flag anything that needs to be arranged ahead of the visit, such as tenant notification or access to a locked mechanical room. If the situation is urgent, let us know and we will go through what the schedule allows.
Adding a vent to a room that lacks one can help, but only if the system has the capacity and the ductwork can reach it without creating pressure imbalances elsewhere. Closing vents in other rooms to redirect airflow is not the right approach and can cause problems. We go through the options on the call based on what you describe.
Yes, in a few ways. Larger homes typically require higher-capacity equipment, and the duct system has to be able to distribute conditioned air across a greater area. A replacement visit starts with a load calculation and a look at the existing duct layout to make sure the new equipment is sized correctly for the space as it actually exists. Call and we will go through what that assessment involves for your property.
