Legacy Plumbing & Excavation is a locally owned, family-operated company serving Vancouver, Washington with residential and commercial HVAC installation and replacement. Our team includes journeymen who bring real trade experience to every job, and our plumbing background means gas line connections and condensate drain routing are handled in-house rather than handed off to a separate contractor. That coordination can save time and keep your project moving.

We work primarily with homeowners, though we also serve commercial properties throughout the Vancouver area. Whether you need a full system replacement or a new installation from scratch, our licensed team manages the work from initial sizing through final walkthrough.

HVAC Systems We Install & Replace

We install and replace a full range of heating and cooling systems for Vancouver, WA homes and businesses. Whatever your property needs, our team sizes and installs the right equipment.

Gas & Electric Furnaces
We replace aging furnaces and install new gas or electric units, with all gas line connections handled by our own plumbing-licensed team.

Heat Pumps
Heat pumps move heat from the outdoor air into your home rather than burning fuel to generate it, making them a practical fit for the Pacific Northwest’s mild winters. We handle the full installation, including refrigerant line sets and any condensate drain work.

Ductless Mini-Split Systems
Mini-splits deliver zoned heating and cooling without requiring existing ductwork. They’re a strong option for additions, older homes, or spaces that aren’t connected to a central system.

Central Air Conditioning
We install central air conditioning as a stand-alone cooling system or paired with an existing furnace, including the condensate drain line routed correctly.

Commercial HVAC Installation & Replacement
Our commercial work covers installation and replacement for businesses and commercial properties in the Vancouver area. We bring the same licensed, journeyman-level approach to commercial jobs as we do to residential ones.

Repair or Replace? How to Read the Signs

Not every struggling HVAC system needs to be replaced, but some are past the point where repair makes financial sense. A few straightforward benchmarks help homeowners decide.

System age: A system 15 or more years old is generally a replacement candidate, even if it’s still running.
Repair cost vs. replacement cost: When a repair quote exceeds half the cost of a new system, replacement is usually the better investment.
Performance and energy bills: A system that runs constantly without holding temperature, or one that’s pushed your energy bills noticeably higher without any change in usage, is telling you something.

What to Expect During an HVAC Installation

Every installation starts with a load calculation to size the new equipment correctly for the square footage, insulation, and layout of your home. Undersized equipment won’t keep up; oversized equipment short-cycles and wears out faster.

From there, we remove the old unit, install and connect the new system, handle any ductwork modifications, and take care of gas line or condensate drain work in-house. Once the system is running, we test it fully before handing it over and close every job with a walkthrough of the controls and maintenance schedule so you know exactly what you have. We also pull the required mechanical permit as part of the process, so you don’t have to track that down separately.

HVAC Permits & Local Requirements in Clark County

HVAC installation and replacement in Vancouver, WA and the surrounding Clark County area generally requires a mechanical permit, processed under Washington’s 2021 state building codes. Properties inside Vancouver city limits are typically permitted through the City of Vancouver, while homes and businesses in unincorporated Clark County go through Clark County Community Development. If your project involves a heat pump conversion, an electrical permit for the dedicated circuit feeding the outdoor unit may also be required, generally through the City of Vancouver or the Washington State Department of Labor & Industries, depending on where your property sits. Legacy Plumbing & Excavation handles required permitting as part of the installation process, so those steps are covered without extra coordination on your part.

We serve Vancouver, WA and communities throughout Clark County, including Battle Ground and Salmon Creek. If you’re not sure whether your address falls within our service area, give us a call and we’ll let you know.

Heat Pump vs. Furnace: Choosing the Right System for Your Vancouver Home

The choice between a heat pump and a furnace comes down to how each system produces heat and how well that fits the Vancouver, WA climate. A heat pump doesn’t generate heat by burning fuel. Instead, it moves existing heat from the outdoor air into your home. Even when outdoor temperatures feel cold, there’s usable heat energy in the air, and a heat pump extracts and transfers it efficiently. That’s why heat pumps are widely used across the Pacific Northwest, where winters are mild compared to colder inland regions.

A furnace takes a different approach, generating heat by burning natural gas or using electric resistance heating elements. Furnaces deliver strong, reliable heat output and remain a practical choice where gas service is available or where backup heat capacity matters.

For homes without existing ductwork, ductless mini-split systems offer a third path: zoned heating and cooling room by room, without the cost and disruption of installing full duct runs. Central air conditioning works well for homes that already have ductwork and want a complete cooling system, either as a stand-alone installation or paired with an existing furnace.

Our team can walk through the options with you and recommend the system that fits your home’s layout, existing infrastructure, and budget.
