A new furnace is a two-decade decision, and the options multiply quickly. You can choose an 80 percent AFUE unit or a mid-90s condensing model, single-stage, two-stage, or modulating burners, and a standard PSC blower or a variable-speed ECM motor that uses less electricity and evens out temperature swings. Which mix is right depends on your Novato, CA home, the length of your heating season, and the behavior of your ductwork. That is why Novato HVAC begins with a load calculation rather than matching the old unit's BTU rating. An oversized furnace short-cycles and overshoots, delivering comfort in bursts while it wears itself out. A properly sized one runs longer, quieter, and more cheaply.
How long a furnace lasts is largely settled the day it goes in. Condensing models produce acidic condensate that has to be trapped, sloped, and drained properly, and their PVC intake and exhaust pipes must be sized, pitched, and terminated exactly as the manufacturer specifies. Get those details wrong and you can expect nuisance lockouts, or worse, flue gas where it does not belong. The gas line needs a sediment trap and a leak-tested connection. The ductwork has to deliver the airflow the furnace was designed for, so our experienced technicians take static pressure readings instead of assuming, and correct duct chokepoints while everything is open when the readings call for it. We also handle permits wherever they apply.
The last hour of the job matters as much as the first. Our technicians analyze combustion, set gas pressure to spec, check temperature rise against the data plate and tune the blower to it, confirm the vent is drafting, and watch the furnace through complete cycles. That process is called commissioning, and it is standard on every Novato HVAC install. We then show you how the thermostat works, where the filter goes, and what normal looks like for the first season.

Signs You Need Furnace Installation in Novato
Catching these issues early helps you avoid costly problems and protect your property. Here are the most common indicators that it's time to call a professional:
- Heating bills climbing while the house never feels quite warm
- Uneven heat, frequent cycling, or rooms that stay cold no matter what
- Your existing furnace has passed fifteen to twenty years of service
- Booming ignition, rust, or soot that keeps coming back after service
- A new air conditioner or heat pump is going in and the old furnace cannot keep up
- Your heat exchanger is cracked, taking repair off the table
- Service calls that come more often and cost more every year
- Fan noise loud enough to interrupt conversation or sleep
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Don't wait, get Novato HVAC on the phone at (415) 234-7418 and we'll take a look right away.

Why Professional Furnace Installation Matters
Furnace installation concentrates the highest-consequence details in residential work. Venting on a condensing furnace must follow the manufacturer's tables for size, length, slope, and termination; get it wrong and the furnace locks out on pressure faults, or worse, flue gases end up where they should not. Gas piping must be sized for the load, trapped for sediment, and leak-tested with instruments. Condensate is mildly acidic and continuous all winter; an unsloped drain line becomes a lockout in January or a slow leak into the framing. None of this is visible in a photo of a finished install, which is exactly why it is where corners get cut.
Sizing and commissioning are the other half of the story. A furnace picked by rule of thumb is usually oversized, and an oversized furnace lives a hard life of short cycles while delivering worse comfort. Our experienced technicians size from a load calculation, then commission with instruments: combustion analyzed, gas pressure set, temperature rise measured and the blower adjusted to hold it in the rated band, static pressure checked so the duct system and furnace are not fighting each other. That final hour of measurement is what turns a box of parts into twenty years of quiet heat, and it is standard on every Novato HVAC installation.
What to Expect From Our Furnace Installation
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's how we handle furnace installation from start to finish:
Sizing & Site Assessment
We size the furnace from your home's actual heat loss and inspect the ductwork, gas supply, and venting path, rather than copying the BTU rating of the unit being retired.
Choices & a Firm Price
We explain what each choice really gets you, from 80 percent units to condensing models, staged or modulating burners, and ECM blowers, then give you a firm installed price. No upselling, just straight answers.
Installation to Code
Our technicians install the furnace, pipe the gas with a proper sediment trap, route venting and condensate lines exactly to spec, and seal the plenum connections, pulling permits wherever required.
Commissioning & Walkthrough
Combustion is verified, gas pressure is set, and blower speed is dialed in to the rated temperature rise before we run full cycles. Then we show you the thermostat, filter, and maintenance schedule.
How to Prevent Furnace Installation Problems
Smart maintenance is almost always cheaper and easier than an early replacement. Here are our expert recommendations:
- Stick to modest setbacks, because a properly sized furnace runs best at a steady pace
- Have the furnace inspected each autumn to keep burners tuned and readings on target
- Keep the installation documents and model numbers handy for fast, accurate future service
- Start a regular filter schedule right away, since good airflow protects the new furnace
- Move chemicals like chlorine, paint, and solvents away from where the furnace draws its air
- Keep the condensate trap and drain clear on condensing models, especially before winter
- Keep intake and exhaust terminations clear of snow, leaves, and nesting insects
Should You DIY or Call a Pro?
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Sizing | Size matched to the old nameplate | Load calculated from the home itself |
| Venting | Improvised pipe runs and terminations | Vents built to spec and draft-tested |
| Gas Piping | No leak test, no sediment trap | Sized, trapped, and leak-tested |
| Condensate Drain | Drain line with no real slope | Drain routed and sloped to spec |
| Ductwork | Old ductwork assumed to be fine | Static pressure measured, restrictions fixed |
| Startup Testing | Turned on once and called finished | Combustion, gas pressure, and rise verified |
