Two kinds of calls come in. The first is from someone whose system has stopped entirely: no heat, no cool, nothing running. The second is from someone whose system is running but not doing its job, a house that never reaches the set temperature, a room that is always too warm, a unit that cycles on and off without making a dent. We take both, and we treat them the same way: scope the problem on the call, confirm the price before anything is scheduled, and test the system before the visit ends.
Los Gatos is a city where a lot of the housing stock was built before cooling was standard, and where the push toward electrification has made heat pump questions a regular part of the conversation. Whether you are dealing with a furnace that will not fire, an AC that has never been installed, or a heat pump you are considering for the first time, call us and we will handle the rest. That is what we do here, for homeowners, for rental properties, and for commercial spaces that need the system working regardless of what is happening outside.
An old thermostat that reads the temperature wrong, fails to trigger the system on time, or simply cannot communicate with modern equipment is not a minor inconvenience. It changes how the whole system behaves. A furnace or heat pump that is getting bad instructions from a faulty control will short cycle, overshoot, or run longer than it needs to, and those habits show up in energy bills before they show up as a breakdown.
Replacing a thermostat on its own is sometimes the right call, and it does not require replacing anything else. A programmable or smart control can hold a more consistent temperature, respond to occupancy, and give you a clearer picture of what the system is actually doing. The visit covers compatibility with the existing equipment, the wiring on the equipment side, calibration, and a full system test before we leave. If the control is the problem, fixing the control fixes the behavior.
Not every older system can accept a smart thermostat without adjustment, and the wiring that worked fine for a basic control may need attention before a new one will operate correctly. That is part of what the visit covers. We check compatibility first, explain what the upgrade involves, and confirm the price before any work proceeds.
Sometimes a thermostat swap reveals that the system it is controlling has a deeper problem. A control that is reading correctly but triggering a furnace that will not ignite, or an AC that runs without cooling, points elsewhere. The diagnostic visit covers both the control and the equipment, so the real cause is identified rather than assumed.
The price for a repair or installation is not a number that exists before the job is scoped. What the fault turns out to be, where the equipment is located and how accessible it is, whether a repair makes sense or a replacement is the better answer, and what parts are involved all affect what the visit costs. There is no figure on this page because the honest answer is that the figure comes from the call.
What does happen on the call is this: the job is described, the scope is discussed, and a rate is confirmed before anything is scheduled. If the diagnostic uncovers something beyond the original scope, the updated price is explained before any additional work proceeds. You know what the visit covers and what it costs before anyone comes out.
The questions worth asking when you call are whether the situation calls for a diagnostic visit or a replacement quote, what the service-call fee includes, and whether the repair or the replacement is the more practical path given the age and condition of the equipment. Those are fair questions and they get straight answers.
A system that is completely down does not get a different process, it gets the same one faster. The scope is confirmed on the call, the price is discussed before anything is scheduled, and the visit covers a full diagnostic rather than a guess at the most likely cause. We take short-notice and emergency calls every day from 9:00 AM to 8:00 PM.
A tenant without heat or a business that has to stay open through a repair visit needs a clear answer on timing and scope before anyone shows up. We work around occupied properties. The scope and the price are settled on the call, and the person managing the property gets clear notes on what was found and what was done, so there is a record of the work.
Call (650) 955-4592, describe what the system is doing, and we scope the job on the phone.
The price is confirmed before the visit is scheduled. If you want a call before the technician arrives, mention it when you book and we will note it. The system is tested before the visit ends, not just the part that was replaced.
Ductless mini-split systems solve a specific problem: a space that needs heating or cooling but has no practical path to duct it. That covers a room above a garage, a converted attic, an addition that the original duct system never properly reached, and older homes where the existing ductwork is in poor enough condition that extending it would cost more than the alternative.
A mini-split installation places an outdoor compressor unit, routes refrigerant line sets through a small wall penetration, and mounts an indoor air handler in the space being conditioned. Each indoor unit conditions the room it serves, which means a room that has always been too warm in summer or too cold in winter can be addressed without touching the rest of the system. The refrigerant charge is set during commissioning, and the unit is tested through both heating and cooling modes before the visit ends.
Mini-splits also make sense as a first cooling installation in a home that has never had central air. The Bay Area's mild climate historically made cooling feel optional, but recent heat events have changed that calculation for a lot of households. A ductless system can be added without the cost and disruption of running new duct work through an existing structure.
A burning smell at the start of heating season can be dust burning off the heat exchanger, and it may clear on its own. A smell that persists, or one that appears during normal operation, points to an electrical or mechanical issue that needs a diagnostic visit. A musty smell from the vents usually means mold or mildew on the evaporator coil or somewhere in the duct system, and cleaning or air quality treatment addresses the cause rather than masking it.
A furnace that will not ignite, blows cold air, or shuts off before reaching temperature has a short list of likely causes: ignition system failure, a heat exchanger problem, a control board fault, or an airflow restriction. The visit covers all of them. Work is carried out to code on every job, and the repair is confirmed with you before it goes ahead.
A heat pump handles both heating and cooling from a single system, which makes it a practical replacement for a furnace and air conditioner that are both approaching the end of their useful life. The Bay Area's mild winters mean heat pumps operate efficiently here through most of the year. A replacement quote covers a load assessment, equipment selection across ducted and ductless options, and a full system test after installation.
An AC or heat pump that runs but does not cool, or one that makes sounds it did not make last season, often points to the compressor or condenser. Refrigerant leak diagnosis, coil inspection, and compressor testing are all part of the visit. A system that has needed refrigerant more than once in a short period is showing a pattern worth investigating rather than repeating.
A room that is always too warm or too cold while the rest of the house is comfortable is usually a duct problem, a zoning issue, or a sign that the system is undersized for the space it is conditioning. The diagnostic visit identifies which of those is driving it. Fixing a duct leak or a damper issue often resolves the imbalance without touching the equipment.
Boilers heat the living space through radiators or radiant floor systems, and the service covers the heating side of that equipment. A boiler that is not reaching temperature, losing pressure, or making unusual sounds gets the same diagnostic process as any other heating system: identify the cause, confirm the repair, test before leaving.
The visit starts with a diagnostic, not a repair. The technician assesses the equipment, identifies what is causing the problem, and explains what was found before any work is agreed. You get a clear picture of what the repair involves, what it costs, and what the alternative is if replacement makes more sense than repair.
Clear notes on what was found and what was done go with every visit, so there is a record of the work. The system is tested before the visit ends. You do not need to know what is wrong before you call. Describing the symptom is enough to scope the visit and confirm the price before anyone comes out.
We serve Los Gatos and the surrounding area, including Monte Sereno, Cambrian Park, Campbell, Saratoga, and Lexington Hills. Properties throughout this part of Santa Clara County are within our service range. If you are not sure whether your address is covered, a quick call settles it. Most of the practical detail sits on our services page for heating and cooling work.
Yes. A filter that has not been changed in a long time can restrict airflow enough to affect both comfort and system efficiency, and a thermostat that is reading incorrectly can cause a system to run more than it should. Neither issue requires a full diagnostic, and both are worth addressing on their own.
Brand matching is rarely the deciding factor. The more important considerations are whether the new equipment is sized correctly for the space, whether it is compatible with the existing duct system and controls, and whether the efficiency rating fits the property's energy use. We walk through the options before anything is ordered.
If the technician identifies a separate issue during the visit, it is noted and explained before the visit closes. Whether to address it right away or schedule a follow-up is your decision, and it is never added to the scope without your agreement.
Yes. A system that has needed the same repair more than once in a short period is telling you something about the underlying condition of the equipment. We factor that history into the recommendation when it is shared with us on the call.
It starts on the phone, where we scope the situation based on what the home has: whether there is existing ductwork in usable condition, how many rooms need cooling, and whether a ducted system or a ductless mini-split makes more sense for the structure. From there, a visit covers a load assessment and a full installation quote before anything is ordered or scheduled.
Ice on the lines or the outdoor coil is almost always a sign that something is restricting the refrigerant cycle, whether that is a low charge from a leak, a dirty evaporator coil, or a blower that is not moving enough air across the coil. Running the system with ice present can damage the compressor, so turning the system off and calling us is the right step.
Once a year is the standard recommendation for a system that is running well, with a check of the cooling side in spring and the heating side in fall if the schedule allows. A system that has had repeated issues or is approaching the end of its useful life may benefit from more frequent attention.
Yes. We serve the communities around Los Gatos, including Lexington Hills and the surrounding area.

Whether you are dealing with a system that stopped working this morning or planning a seasonal tune-up before temperatures shift, we cover the full range of residential and commercial heating-and-cooling work across Los Gatos and Santa Clara County. The table below lays out what each service covers, who it fits best, and a practical note to help you decide where to start. Call us with any question and we will scope the job on the phone before anything is scheduled.
| Service Type | What It Covers | Common Needs | Things to Know |
|---|---|---|---|
| Ductwork Repair & Sealing | Duct inspection and leak detection, Sealing or repair where needed, Airflow assessment after sealing, Identification of rooms with uneven coverage | Homes with uneven room temperatures, a system that runs constantly, or a spike in energy bills without an obvious equipment cause | Fixing leaking ducts often makes a bigger difference to comfort and energy use than adjusting the equipment itself. |
| Wildfire-Smoke Air Filtration (MERV-13+) | Compatibility check on existing air handler, MERV-13 or higher filter installation, Airflow assessment after upgrade, Review of filter replacement schedule | Santa Clara County households affected by recurring wildfire smoke seasons who want filtration that goes beyond a standard residential filter | Standard one-inch filters are not rated to capture the fine particulates wildfire smoke carries. MERV-13 and higher addresses that gap, but the air handler needs to handle the added resistance without straining the blower. |
| Full System Installation & ReplacementMost Popular | Load calculation for the space, Equipment selection based on actual building needs, Full installation scope breakdown, System tested before visit closes | Homes or commercial spaces where repair costs have climbed or efficiency has dropped enough to show up in energy bills | A load calculation sizes the new system to the building rather than matching the old unit. Oversized equipment short-cycles and undersized equipment runs constantly. |
