Heat You Can Actually Count On
An aging furnace rarely fails all at once — it fails slowly. Heating bills creep up. Some rooms stay cold no matter what the thermostat says. Repairs start adding up, but never quite fix the problem. And when temperatures drop in King County, your system gives out at the worst possible moment.
Ranger replaces struggling systems with high-efficiency furnaces built for Pacific Northwest homes.
We start with a free in-home assessment, walk you through clear recommendations for your space and your budget, and offer hassle-free payment options so cost never gets in the way. Most installs are completed in a single day, backed by our lifetime warranty so you're covered for the long haul.
No upsells. No pressure. Just heating that finally does its job.
Why Homeowners Choose Ranger
A new furnace is a major investment — and the install matters as much as the system itself.
King County homeowners pick Ranger because we get the details right, treat your home with care, and stand behind every job for life.
Right-Sized For Your Home
We don't sell whatever fits the budget. We measure your home, your ductwork, and your heating needs — then recommend a system built to handle them. A right-sized furnace runs more efficiently, heats every room evenly, and lasts longer.
Clean, Careful
Installs
Every installation begins with shoe covers at the door and drop cloths in the work area. Connections and wiring are run cleanly, every system is fully tested before we leave, and your home is left as clean as when we arrived.
Honest
Recommendations
You'll get clear options matched to your home and your budget, not pushy upsells or hidden fees. We walk you through the trade-offs in plain language, answer every question, and let you decide on your timeline.

Why waiting until winter costs you more
An aging furnace always seems to fail at the worst possible time — usually the coldest week of the year, when every HVAC company in King County is already booked solid. That means:
✓ Repair calls stacked behind dozens of others
✓ Back-ordered parts and longer wait times
✓ Limited scheduling during peak cooling season
✓ Higher monthly bills from running an inefficient system
Planning ahead changes the math. Off-season scheduling is faster and more flexible. You'll have time to compare options, pick the right system for your home, and use our hassle-free payment plans without rushing the decision.
The best time to replace a furnace is before it breaks.
Our Happy Customers
I will be recommending Ranger to everyone I can... Best customer service ever. I can’t say enough about how impressed I am with this company. They have gone out of their way from the first time I contacted them to make sure we had a great experience. They just finished installing a whole new system!!! It took two days and they worked almost 12 hours the second day to get it done and functional so we would have heat for the night. I was blown away by how cleanly they installed everything. Their technicians are knowledgeable and very friendly. I will be recommending Ranger to everyone I can.
Great team! They showed up on time, every time they came out, they were clear and upfront about the time and the cost, they cleaned up everything. The installers made sure we knew how to work our new system. We were so happy with the salesman, customer service on the phone, and the installers.
We should have done it sooner! Everything from sales to post installation was great. All went as explained and expected. Ryan, from sales, has been super with his knowledge and care. The system is great. We should have done it sooner.
I felt confident...I was extremely impressed with estimate I received from Ranger. Ryan was knowledgeable, professional, and took the time to explain the options available to me. The estimate was detailed and easy to understand. I felt confident in their recommendations and commitment to providing quality service.
Ranger got it right! It's rare to get top shelf customer service along with a top shelf product. We made the leap to get a heat pump mini split system to replace our gas furnace. A little scary, but Ranger made it an easy decision. Everyone that I dealt with at Ranger was very knowledgeable and they are clearly committed to their customer having a positive experience. I'm very impressed.
We chose to stay with Ranger... We made an appointment with Ranger to have our home evaluated for installing a cooling system. It was comforting seeing a familiar face when Ryan was at my door today. Ryan and team were out to install our new furnace back in 2021. We chose to stay Ranger with due to the exceptional service they provide. Ryan presented all options available and answered all questions in great detail as we thought of them. He was professional, knowledgeable, patient and asked questions about our wants/needs with the cooling unit and set clear expectations on what to expect going forward.
Frequently Asked Questions
How long does installation take?
Most furnace installs are completed in a single day. The exact timeline depends on the condition of your existing system, ductwork, and venting, but the same crew handles the whole job from start to finish. We'll walk you through the schedule during your free estimate.
What does your lifetime warranty cover?
Our lifetime workmanship warranty covers the installation itself — for as long as you own your home. If anything we touched fails because of how it was installed, we come back and fix it at no charge. Your equipment is also covered by the manufacturer's warranty, which we'll explain during your estimate.
What financing options do you offer?
We offer hassle-free payment plans designed to keep monthly costs manageable. Many homeowners use financing to upgrade to a higher-efficiency system without straining their budget. We'll review your options during your free estimate and help you pick the right plan.
Will a new furnace lower my energy bills?
In most cases, yes. Older furnaces often run at 60–80% efficiency, while modern high-efficiency furnaces operate at 90–98% efficiency. That means less fuel wasted to heat your home — and most homeowners see noticeably lower monthly bills along with more consistent comfort.
How long will my new furnace last?
A properly installed and maintained furnace typically lasts 15 to 20 years or longer. Modern systems are built with improved efficiency and durability, and routine maintenance — like seasonal filter changes and annual tune-ups — helps extend system life even further.
What brands do you install?
We install premium, industry-leading systems from Trane to Daikin and other top manufacturers, chosen for reliability and long-term performance in Pacific Northwest homes. During your estimate, we'll recommend the right brand and model for your space, your goals, and your budget.
