How Long it Takes to Install a New HVAC System in Yakima

April 28, 2025

If you're planning to upgrade your HVAC system, one of the first questions you might have is how long the installation process will take. For homeowners in Yakima, understanding the timeline helps with planning, scheduling, and staying comfortable during Washington’s cooler and warmer months. 

At Campbell & Company, we specialize in HVAC installation throughout Yakima and Ellensburg. With decades of experience and a team that understands the unique challenges of both older and newer homes, we provide professional installations with minimal disruption. While timelines can vary based on your system type and home size, we’re here to break down what you can generally expect. 

Every project is unique. For a detailed estimate tailored to your home, we recommend contacting our team directly. 

General Timeline Estimate for HVAC Installation in Yakima 

The total time it takes to install a new HVAC system depends on several key factors. However, most standard installations follow a typical range. 

  • Standard HVAC systems: 1 to 3 days
  • Ductless mini-split systems: 1 to 2 days
  • Complex projects: 3 to 5 days 

Simple changeouts, where an older system is being replaced with a similar model, often fall on the shorter end of this range. If new ductwork, electrical upgrades, or zoning is involved, the timeline can be extended. No matter the scope of your installation, Campbell’s team works efficiently to keep the process on track without cutting corners.

Square Footage and Its Impact on HVAC Installation Time 

The size of your home plays a major role in how long HVAC installation takes. Smaller homes in Yakima and Ellensburg may only require one to two days for installation, particularly if the system type and layout are straightforward. Larger homes or multi-story properties often take two to three days or more. 

Square footage impacts not only the size of the HVAC equipment required but also the number of vents, ducts, or indoor units needed. Homes in the Tri Cities with open layouts may allow easier access, while older properties in Yakima with tight crawlspaces or limited attic access may require more time. 

In addition to space, the condition of existing ductwork or electrical systems can influence the schedule. Upgrades to bring your system up to code may add an extra day but are essential for safe, efficient operation. 

System Type: Ductless Mini-Split Installation 

Ductless mini-split systems are a popular choice in Yakima homes thanks to their energy efficiency and flexibility. These systems typically take less time to install because they do not rely on ductwork, which makes them ideal for older homes, additions, or areas with specific climate needs. 

For a single-zone ductless mini-split, installation usually takes one day. If your system includes multiple indoor units or zones, the timeline may extend to two days. 

Mini-splits also involve precise placement and wall mounting for each unit, as well as outdoor compressor setup. Our technicians take the time to ensure each component is installed correctly to support long-term performance and comfort. 

Local Considerations in Yakima 

Beyond home layout and system type, local factors in Yakima and the surrounding areas can affect installation time. 

  • Weather conditions: Extreme cold or heat may require rescheduling or limit the amount of time technicians can work outdoors.
  • Permitting requirements: In some cases, HVAC permits may take a day or two to process before work can begin.
  • Accessibility issues: Older Yakima homes may present challenges such as limited attic access, blocked ductwork, or outdated wiring. These conditions can add time to the project but are addressed with care to maintain safety and quality. 

Campbell’s team is familiar with these local variables and can plan accordingly to minimize delays.
