Furnace Installation and Furnace Repair, Built Around the Furnace Itself

Furnace installation in Napa comes down to details many quotes skip: the right furnace for your house, venting that fits it, a proper gas connection, and a condensate drain on high-efficiency models. Furnace repair is the same story at the component level, from a worn ignitor to a failed blower. We handle both, and we tell you plainly which one your furnace needs.

Furnace Sized to the House

Matched to your home's actual heating load, not to the old unit.

Component-Level Diagnosis

We find the part that failed, not just the symptom.

Venting and Gas Checked

Flue, gas connection, and drain confirmed before the new furnace goes in.

One Honest Price

One price before work starts, for a repair or a replacement.

Gas Furnace Installation: Choosing the Right Furnace

A gas furnace comes in single-stage, two-stage, and variable-speed models, with efficiency ratings that decide how it vents and drains. We walk you through the options for your house and your budget, and as a Factory Authorized Bryant dealer we install Bryant furnaces. Weighing a furnace against a heat pump? That comparison lives on our heating installation page.

Single-stage, two-stage and variable-speed

How the furnace modulates heat output.

Efficiency rating (AFUE)

What you pay for and what you save

Venting and flue

Matched to the furnace you choose.

Gas line and connections

Checked and connected to suit the new unit.

Condensate drain

Required on high-efficiency models, planned in from the start.

Furnace Replacement: What the Swap Involves

A furnace replacement is more than lifting out the old unit. We remove it, check that the plenum, venting, and gas connection suit the new furnace, set it, connect the thermostat, and run a full heating cycle before we leave. Furnace installation cost depends on the model, the efficiency level, and whether the venting has to change, so we scope the house first and give you one price.

Furnace Repair in Napa: Problems We Fix

Our furnace repair starts at the component that failed, not at the symptom. A technician checks ignition, flame, heat exchanger, blower, and controls, then tells you what failed and what the fix costs. For cold rooms, uneven airflow, or ductwork-related comfort problems, see our heating repair page.

Furnace Not Heating

Usually an ignition, gas, or limit switch problem, or a safety control that has tripped. We trace which one before we replace anything.

Furnace Blowing Cold Air

Often a dirty flame sensor, a failed ignitor, or a tripped limit switch, and sometimes just a thermostat fan setting. Quick to check, and often quick to fix.

Furnace Won't Ignite

A worn ignitor, a gas valve problem, or a blocked vent can keep the burners from lighting. We test each one before recommending a part.

Furnace Short Cycling

A furnace that starts and stops every few minutes often has a dirty flame sensor, restricted airflow, or a limit switch that is overheating. We find the cause and fix it, instead of resetting the furnace and leaving.

Furnace Flame Sensor and Ignitor Replacement

Cleaning or replacing a flame sensor and replacing a worn ignitor are two of the most common furnace repairs. Small parts, big symptoms, and we carry common ones on the truck.

Furnace Heat Exchanger Cracked? What Happens Next

A cracked heat exchanger is a safety issue, not a repair to put off. If we find one, we show you what we see and explain your options.
