Air conditioning installation in Tiburon is rarely about raw cooling power. Bay breezes keep most days mild, but afternoon sun on west-facing glass can push a living room or a primary bedroom well past comfortable while the rest of the house stays cool. A new system has to handle those rooms, run quietly on a hillside where sound carries, and hold up in salt air that wears out outdoor equipment faster than it does inland. That is what we plan for on every Tiburon installation, from cottages near the downtown shops to large houses on the hills.
Size it for the rooms that actually overheat
We start with a Manual J load calculation, room by room. On the peninsula the numbers swing on glass area and orientation, skylights, ceiling height and shade, so two houses of the same size can need very different equipment. An oversized unit cools the view room in short bursts, shuts off before it removes moisture and costs more to run. An undersized one falls behind by late afternoon.
The calculation also shows whether central air is the right answer at all. If only two or three rooms overheat, ductless mini-splits may cool them better than a whole-house system. If the furnace is near the end of its life too, a heat pump can do both jobs with one outdoor unit, which is usually the smarter spend in a town where heating runs far more hours than cooling.
Where the outdoor unit goes
This is where Tiburon installations take the most thought. Lots are steep, side yards are narrow, and neighbors and HOAs care about noise and views. We look for a spot that:
- keeps the condenser away from bedroom windows, yours and the neighbors’;
- gives the coil the airflow clearance the manufacturer specifies;
- stays within the allowed refrigerant line length to the indoor coil;
- can be reached for service without crossing a planted terrace or someone else’s yard;
- is out of direct wind and spray on waterfront lots.
Variable-speed condensers spend most of their time at low speed and are noticeably quieter than single-stage units, which helps on tight lots. A solid pad or wall brackets, vibration isolators and a neat line-set cover finish the job.
Built for salt air
Salt deposits on fins and copper speed up corrosion, and a corroded outdoor coil is a common reason peninsula systems start leaking refrigerant years early. Where the manufacturer offers a coated or coastal-protected coil, we price it as an option. We use corrosion-resistant fasteners, keep the unit off bare soil, and show you how a gentle fresh-water rinse of the coil, with the power off, helps between visits. A yearly AC tune-up catches corrosion before it turns into a leak.
Ductwork in large and older houses
Ducts that were sized only for a furnace are often too small for cooling, which needs more airflow than heating. In larger homes with long runs and several levels, we check duct sizes, seal leaky joints and look at whether zoning, with separate thermostats and dampers for the upstairs, the main floor and the view rooms, will keep the sunny side comfortable without overcooling the rest. Some homes are better served by two smaller systems than by one large one.
How the installation runs
- Consultation. We walk the house with you and talk about the rooms that bother you and your budget.
- Load calculation. Manual J sizing, room by room.
- System selection. Options with an upfront, itemized quote. Financing is available with approved credit.
- Installation. Permitted work, installed to the manufacturer’s instructions, with the line set pressure-tested and evacuated before refrigerant is released.
- Testing and walkthrough. We measure airflow, temperature split and charge, go over the manufacturer’s warranty and show you the thermostat and zones.
