A new air conditioner should be a fifteen-year decision, and the installation day determines most of it. The industry's open secret is that a poorly installed system gives up a large slice of its rated efficiency before it ever cools a room: an oversized unit short-cycles, dehumidifies poorly, and leaves a Novato house cold but clammy; an undersized one runs flat-out and never catches up on the worst afternoons. That is why Novato HVAC starts every installation with a real load calculation, measuring your home's square footage, insulation, window exposure, and duct system, instead of matching the tonnage bolted to the wall by the last contractor.
Equipment selection comes next, and we keep it honest. Today's systems are rated under SEER2, and the jump from a builder-grade single-stage unit to a multi-stage system buys quieter operation, longer and gentler cycles, and far better humidity control, worthwhile for some homes and unnecessary for others. Our experienced technicians walk you through the real trade-offs, then install to the details that decide performance: a correctly sized and pressure-tested line set, a deep vacuum pulled and verified with a micron gauge before any refrigerant flows, the charge dialed in by weighed-in measurement and confirmed with superheat and subcooling, a properly trapped and sloped condensate drain with a float safety, and airflow verified against static pressure so the new equipment is not strangled by the old ductwork.
We finish with commissioning, not just a thumbs-up: temperature split measured, amp draws recorded, thermostat configured, and the whole system run through complete cycles while we watch it work. We take care of permit paperwork where it is required, and we haul away the old equipment when the job is a changeout.

Warning Signs for AC Installation
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. Watch for these telltale signs that professional help is needed:
- A system that has already passed its twelfth to fifteenth summer
- A system that runs nonstop on hot afternoons without hitting the setpoint
- A major repair, like a dead compressor or leaking evaporator, on aging equipment
- The system still uses phased-out R-22 refrigerant
- Hot spots and warm rooms the AC can never catch up with
- The house feels cold but sticky, a classic sign of oversizing
- Summer energy bills that keep rising as comfort drops
- Repair calls that keep coming, with bigger bills every time
Act Before It Gets Worse
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. Call Novato HVAC at (415) 234-7418 at the first sign of trouble.

Why Professional AC Installation Matters
A new AC can blow cold on day one and still be doomed. Moisture left in a line set that was never properly evacuated forms acid that slowly destroys the compressor. A refrigerant charge set by feel rather than by weight drains efficiency with every cycle. An oversized system, chosen without a load calculation, short-cycles itself into an early grave and never dries the air. Installation is where a system's future gets decided, and none of these errors reveal themselves until the repair bills and utility costs start climbing.
Our experienced technicians do the unglamorous steps that make equipment last: nitrogen pressure testing before evacuation, a micron-gauge-verified vacuum, charge set by weight and confirmed against measured superheat and subcooling, condensate drainage with a proper trap and overflow protection, and airflow verified with static pressure readings rather than a hand held over a register. Refrigerant handling itself is federally regulated, and the recovery and evacuation equipment involved is not a hardware-store purchase. Done right, an installation disappears into fifteen quiet years of cold air, and that is the outcome we commission every job to deliver.
How Our AC Installation Works
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's exactly how the AC installation process unfolds:
Load Calculation & Assessment
A real load calculation, based on how your home is built and how it faces the sun, tells us the right capacity. We inspect the ducts during the same visit.
Options & Firm Quote
We explain where each option, from single-stage to variable-speed, makes sense for your home and budget, then quote a firm installed price. You pick the system, without any sales pressure.
Installed to Spec
The line set is pressure-tested, a deep vacuum is pulled and confirmed with a micron gauge, the refrigerant is weighed in, and the condensate drain is trapped and fitted with a float switch.
Startup & Walkthrough
We verify superheat, subcooling, temperature split, amp draws, and airflow, configure the thermostat, walk you through the system, and haul the old equipment away.

A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Start with these practical measures our team relies on:
- Use reasonable thermostat setpoints; giant setbacks force long recovery runs in peak heat
- Flush the condensate line each spring so the float switch never has to save you
- Leave all supply and return registers open so airflow stays balanced the way it was set up
- Run a professional tune-up every spring to keep the charge and amp draws on spec
- Start a regular filter schedule on day one to protect the new coil from restricted airflow
- Keep the outdoor unit rinsed clean and clear of vegetation on all sides
- Deal with small warning signs quickly, because a weak part caught in April rarely becomes a midsummer failure
DIY vs. Professional AC Installation
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Equipment Sizing | Rule-of-thumb tonnage | Capacity matched to your home's actual load |
| Vacuum | Moisture trapped in the lines | Deep vacuum verified with a micron gauge |
| Charge | Beer-can-cold guesswork | Set by weight, checked with superheat and subcooling |
| Ductwork | New unit strangled by old ducts | Airflow verified with static pressure readings |
| Drainage | Untrapped drain, ceiling damage later | Drain trapped and protected against overflow |
| Verification | It blows cold, ship it | Complete commissioning before we leave |
