The Top 8 Residential HVAC Contractors In Seattle 2024 (Ratings & Reviews)

Seattle's Top HVAC Residential Contractors

In the Puget Sound area, we have rainy cold weather in the winter, and every summer it seems to keep getting hotter.  If you Google ‘residential HVAC contractors to try and fix or replace your system, you will have many companies to choose from.

And when those companies all claim to be Seattle’s #1 residential HVAC contractor, how do you know which company is the right one for your project?

Naturally, we want to say Evergreen State Heat & AC / Evergreen Eastside Heat & AC are the best providers in Puget Sound!   We think we’re pretty great and so do both Google 5-Star and the Better Business Bureau.  Our reviews are regularly amongst the highest in the industry and many of our customers can confirm this!

And while we would love the opportunity to service or replace your existing HVAC system, that doesn’t automatically make us the best fit for you. Every contractor has their own niche within the industry.  Some companies, like us, specialize in custom designed gas furnace & heat pump/AC units. Others might be really strong in boilers, oil systems, etc.

We are passionate about educating potential prospects and customers about the residential HVAC industry to make sure they can find the right company for their needs.  We identified the top eight (8) residential HVAC companies by size in our market area for you to research.  We spent hours investigating each company’s license history, online reviews, websites, services offered, BBB accreditation, and when they started business in the local area.  All so that you don’t have to!

All of these criteria are important when choosing a reputable company for you as a consumer. I’m sure you’re asking, “Why would you create this list and not put yourself on it?”  Whether you choose Evergreen or not, it is more important to us that you find the best company for your project.

These are the top eight (8) residential HVAC contractors in the Seattle/Bellevue/Everett area in which we serve listed alphabetically.

Choosing the right Residential HVAC Provider for you

We highlighted 10 of the most popular residential contractors in the local area and stacked them up head-to-head based on permit totals, online reputation, and services offered. If you’re still worried about which one is right for you, we’ve put together a resource to describe what you should be looking for in a residential HVAC provider.

A Little about Evergreen State

After being in business since 1968, and locally owned by Russ & Pam Kimball since 1998, we would be remiss if we didn’t tell you who Evergreen is a good fit for. While things like our 5.0 Google rating, and an A+ rating with the Better Business Bureau are important, that doesn’t tell you if you’re a good fit. You should consider Evergreen if you are looking for a company who:

  • Offers great value but isn’t always the lowest price.
  • Has the best warranty in the industry.
  • Will help you design the system to meet your exact needs.

Our goal is to help make your dreams a reality! Please reach out to us to discuss the process further. We can schedule a time for our Energy Consultants to visit your residence.  They will walk you through the process of designing and planning all the details that are needed to make your home comfortable!
