Furnace and Heating Installation in Poway, CA
For homes and spaces that do not have central heat yet: an addition, an ADU, a converted garage, or an older house that has never had more than a wall heater. We assess the space, size the system for it, and put the options in writing with the price. If you already have a furnace and want to replace it, start with Furnace and Heating Replacement.
How We Size and Match the System
San Diego does not need the furnace a contractor would install in Denver. Oversizing is the default mistake in this county, and you pay for it in short cycling, in noise, and in a system that never settles into a steady run. We calculate the heating load for the space. Capacity picked off square footage is how the oversizing happens.
What we check before recommending anything:
Insulation and windows
An older Poway house and a 2015 build with the same footprint need different equipment.
Ducts and airflow
Whether ducts exist, whether they can carry what the new system produces, and whether new runs are part of the project.
Gas, venting, and electrical
What is available at the installation location, and what has to be added.
The furnace, the blower, the thermostat, and the ducts have to work as one system. Match the equipment and leave the distribution alone, and the homeowner pays for good equipment and gets mediocre heat.
Types of Heating Systems We Install
Gas furnace with ductwork
The standard choice where ducts exist or are being added, and where gas is already at the property. It heats the whole house through one system, and the scope covers the furnace, the venting, and the duct connections.
Heat pump
One system for heating and cooling, with no combustion and no gas line. It suits homes adding both at once, all electric properties, and houses with solar. This is the only category here where rebates are genuinely available. More on our Heat Pump Installation page.
Ductless mini split with heat
For an addition, an ADU, a converted garage, or a room the ducts were never going to reach. Each indoor unit has its own control, and no ductwork is required. More on our Mini Split Installation page.
How Your Furnace Installation Works
- 1
Contact
Call or send the form with the space, what you want heated, and your address. Tell us whether ducts already exist, because that is the single biggest factor in what we bring to the assessment.
- 2
Home assessment
We visit, measure, and check the sizing, the duct situation, the gas and venting availability, and the electrical capacity at the installation location.
- 3
Options and written proposal
You get the options that fit, with the differences explained, and a written scope: equipment, the work included, the price, the schedule, and anything priced separately.
- 4
Preparation and installation
We confirm the date, handle the applicable permits and testing, and install to the agreed scope. Additional work happens only after you approve it.
- 5
Commissioning and walkthrough
We start the system, test combustion and the full heating sequence, clean up the work area, show you the controls, and hand over the documents.
Timing depends on the scope. New ductwork, new venting, gas line work, and electrical upgrades each extend the schedule, and your proposal gives you the dates before anything starts.
What Does Furnace Installation Cost?
We quote after seeing the space, so the number on your proposal is the price of your project.
What affects the price
- Equipment type and capacity, and whether the system heats one space or the whole house.
- Whether ductwork exists. New runs, returns, and registers are a substantial part of a first time installation.
- Venting. A condensing furnace cannot reuse the old flue, so new venting is part of the scope.
- Gas supply and electrical at the equipment location.
- Access. Attic and crawlspace work takes longer than a garage or closet installation.
- Permits and the testing that applies to the work.
Two things worth knowing before you compare quotes. A condensing, high efficiency furnace costs more up front and needs new venting, and in a climate with a heating season this short the payback often does not work. We say so. And there are almost no rebates on gas furnaces, so if rebates matter to your budget, the category to look at is heat pumps.
Once we have seen the property, we put together a written proposal

- Permits and testing

Why Homeowners Choose GVK for Furnace Installation
Sized for this climate
We calculate the load for the space. Oversizing is the standard mistake here, and the only fix afterwards is new equipment.
Honest efficiency arithmetic
Where the more expensive equipment will not earn back what it costs in a short heating season, we tell you that before you sign.
A written scope and price before work starts
Equipment, included work, price, schedule, and anything optional priced on its own. Changes come back to you before they happen.
Permits and testing as part of the project
Heating installations in California need a permit, and most of this work also requires HERS verification. 600+ permitted projects under our license are on public record.
Tested and explained at handoff
We run the full heating sequence, test combustion, and go through the controls with you before we leave.

Furnace Installation FAQ
How much does a heating installation cost?
The price depends on the equipment, whether ductwork exists, the venting, and the gas and electrical work at the location. A first time installation in a space with no ducts is a different project from a furnace going into an existing duct system. You get the number in writing after we see the space.
How is the right size and type chosen?
We calculate the heating load for the space: the rooms, the ceiling heights, the insulation, the windows, and the duct capacity. The type follows from what the space allows. Where ducts do not exist and adding them is impractical, a ductless system usually makes more sense than building a duct network for one room.
How long does the installation take?
A furnace into an existing duct system is often a one day job. Adding ductwork, new venting, gas line work, or electrical upgrades extends it. Your proposal gives you the schedule before anything starts.
Will my ducts or electrical panel need changes?
Sometimes. We check both at the assessment. Ducts that cannot carry the airflow the new system produces get addressed in the scope. For a heat pump, panel capacity is a real consideration, and we check it at the assessment, while you can still price the panel work.
When is a permit or HERS testing required?
A permit applies to the equipment change itself. HERS verification applies to the parts an inspector cannot see finished, such as duct leakage and refrigerant charge, and it is done by an independent rater, not by us. We tell you which of the two your project needs, who files them, and when they are scheduled against the install date.
What happens after I request an estimate?
We confirm your address and what you want heated, arrange the assessment, and then give you the options in writing with the price. You review the proposal before deciding anything.
