Burlingame runs a mix of older residential neighborhoods and smaller commercial properties, and the heating and cooling equipment inside them reflects that variety. Craftsman bungalows and mid-century homes that were never wired for central air sit alongside newer construction that came with a full ducted system already in place. Apartment buildings, small office suites, and retail spaces on the commercial side tend to have packaged rooftop units or split systems that handle multiple zones at once.
What that means in practice is that no two calls come in the same way. A homeowner dealing with a furnace that stopped lighting is a different job from a property manager whose rooftop unit is cycling on and off across a commercial space. We handle both, and everything in between. Questions about the equipment get answered before anything is booked.
Call (650) 879-8929 to get started.
A furnace that smells faintly of burning or produces carbon monoxide readings near the unit is not always a filter problem. A cracked heat exchanger lets combustion gases mix with the air moving through the duct system, and it is not visible from the outside of the unit. An inspection opens the system and checks the exchanger directly. If a crack is found, the options are a component replacement or a full furnace replacement, depending on the age and condition of the equipment. Either way, the scope is confirmed before any work begins.
An AC unit that runs nothing when you call for cooling is one of the more frustrating calls, because the house gets warm fast and the cause is not obvious from the thermostat. Failed capacitors, a seized compressor, a tripped safety switch, or a control board fault can all produce the same symptom. The diagnostic visit works through each possibility in order. Condenser and compressor service is part of that process, and so is checking refrigerant charge once the electrical side is ruled out.
Older homes in this area were often extended without revisiting the duct layout. An addition that shares a return with the original house may never reach the set temperature, because the system was not sized or routed to serve the extra square footage. Ductwork design for an addition starts with the load the new space puts on the system, then works backward to what the supply and return configuration needs to look like. Sealing and rebalancing the existing duct system is often part of the same job.
A system that starts, runs for a minute or two, and then shuts off before the space reaches temperature is not just annoying. Short cycling puts mechanical stress on the compressor and the heat exchanger, and it drives up energy use while delivering less conditioning than a system running its full cycle would. The cause is usually one of a short list: refrigerant loss, a dirty evaporator coil restricting airflow, a thermostat reading incorrectly, or a system that was oversized for the space to begin with. The visit identifies which one it is.
An urgent call gets handled the same way a scheduled visit does: the situation is scoped on the phone first, the price is confirmed before anything is booked, and the system is tested before the visit ends. What changes is the timeline. When a furnace has stopped entirely or an air conditioner quits in the middle of a warm stretch, we take the call and work out what the schedule can accommodate. We are available every day from 5:30 AM to 8:00 PM, including weekends.
For properties with tenants or businesses that have to stay open, the visit gets arranged around occupancy. A retail space that cannot close during business hours, a rental unit where a tenant is working from home, a multi-unit building where one unit is down while the others are fine: these are all situations we work around. The scope and the timing get confirmed on the call so there are no open questions before the visit is arranged.
From a quick tune-up to a whole-system replacement, the diagnosis comes first, and the price follows from what the diagnosis finds. One call is all it takes to get it looked at.
A high-efficiency heat pump or air conditioner carries a rating that was calculated under controlled test conditions. What a property in Burlingame actually sees depends on how well the duct system is sealed, whether the equipment was sized correctly for the load, and whether the installation matched what the manufacturer's spec sheet calls for. A unit that is nominally efficient but installed into a leaking duct system loses a significant share of that efficiency before conditioned air reaches the register.
Energy-efficiency upgrades that actually move the needle usually combine equipment and envelope work. Evaporator coil cleaning restores airflow that has been choked by buildup. Duct sealing recovers conditioned air that was bleeding into unconditioned spaces. A thermostat or smart-control upgrade lets the system run on a schedule that matches occupancy rather than running at full demand around the clock. Each of those is a separate job, and each one has a measurable effect on what the system delivers.
System tuned. Airflow balanced. Home comfortable.
When a system reaches the end of its useful life and replacement is the right call, the new equipment gets sized to the actual load the property puts on it. That is not the same as matching the tonnage of what came out. A unit that was oversized from the beginning short cycles and wears out faster than it should. A unit that was undersized runs constantly and still does not hit the set point on the worst days of the year.
A proper sizing calculation accounts for the square footage being conditioned, the insulation and window quality of the building envelope, the orientation of the structure, and the internal heat load from occupants and equipment. For an addition or a remodel, those numbers may have changed since the original system was specified.
Where a home does not have existing ductwork, or where the existing duct system would need significant work to support a new central unit, a ductless mini-split or multi-zone system is often the more practical path. Each indoor air handler serves a defined zone and runs independently, which suits older construction with irregular floor plans. Central air installation is the right answer for homes where the duct system is already in good shape and the load is suited to it. The visit determines which configuration fits the property.
The price is confirmed on the phone before anything is scheduled, based on what the call describes. A repair quote is confirmed again after the diagnostic, once the fault is identified and the scope is clear. What moves a quote from one number to another is the fault itself, where the fault is located in the system, and whether a repair or a replacement is the better answer once the equipment has been assessed.
On installation work, a written scope is provided before the job starts. That scope covers what is being installed, what the visit includes, and what falls outside it. The electrical circuit and disconnect for a new heat pump or central air system belong to an electrician, and the scope makes that clear. Ask what is covered when you call and you get a straight answer. No guessing, and no open questions before work begins. For a fuller picture of the job, see our page listing every HVAC service.

If the system is not replicating the symptom during the visit, we document what was checked and what was ruled out. Some faults are intermittent and only appear under specific conditions. If the problem returns, call back and describe what the system did. The follow-up visit builds on what was already checked.
Proximity to the airport does not change what the equipment needs or how a job is scoped. What does matter for any property in this area is that the building envelope and duct system are in reasonable condition, because a well-sealed system delivers the efficiency the equipment is rated for. That is true here as anywhere else in the county, and it is part of what the diagnostic visit checks.
Access to the indoor unit, the outdoor pad or mounting location, and any attic or crawl space the work requires should be clear before the visit. If furniture or stored items are in the way, moving them ahead of time avoids delays. We will tell you what to expect when the job is scoped on the call.
Older homes built before central air was standard on the Peninsula are the most common candidates. Many of them have no existing ductwork, which makes a ductless mini-split installation the practical path. The visit assesses the layout and what the existing structure can accommodate before any equipment is recommended.
Fine particulate matter from wildfire smoke passes through standard filters and can coat evaporator coils over time, reducing airflow and making the system work harder. Upgrading to MERV-13 or higher filtration captures those particles before they reach the coil. Compatibility with the existing air handler is checked on the visit, because not every system can draw air through denser filter media without straining the blower.
Whether the call is a repair, a first-time cooling installation, or a full system replacement, the price is confirmed before the work starts.

| System Service | What the Service Includes | Best For | What to Keep in Mind |
|---|---|---|---|
| Heat Pump Repair & Service |
| Homes in Burlingame already running a heat pump that is not reaching temperature or switching modes incorrectly | Burlingame's mild winters are well suited to heat pump operation. A system that blows cool air in heating mode often has a reversing valve or refrigerant fault. |
| Full System Installation & ReplacementMost Popular |
| Homeowners whose system is aging, repeatedly failing, or unable to keep pace with the home's demands | An oversized unit short-cycles and wears out faster. An undersized one runs constantly. Correct sizing is confirmed before equipment is ordered. |
| Ductless Mini-Split Installation |
| Older Burlingame homes without existing ductwork, additions, or spaces where central air cannot reach | Many Peninsula homes built before the 1980s have no duct system. A mini-split avoids the cost of running new ductwork through finished walls and ceilings. |
