At Gene Johnson Plumbing & Heating, we know firsthand how important dependable air conditioning is to your family’s comfort. For over 40 years, our family-owned and operated business has been proud to serve neighbors across the greater Seattle area — delivering heating, cooling, plumbing, and electrical services with care, craftsmanship, and honesty. Whether you’re considering a brand-new air conditioning installation or need expert replacement for an aging system, we’re here to guide you every step of the way, ensuring your home stays a welcoming retreat from the heat.
Mukilteo’s Unique Climate Calls for Smart Cooling
Mukilteo enjoys a temperate climate, with summer temperatures often resting in the mid-60s to low 70s Fahrenheit. While these mild conditions might not require the heavy-duty cooling systems you’d find in hotter states, the region’s occasional heat spikes and humid days still make reliable air conditioning essential for year-round comfort. Beyond the temperature, an efficient AC system also helps regulate indoor humidity and improve the air you breathe — factors vital for a healthy and pleasant home. At Gene Johnson Plumbing & Heating, we understand Mukilteo’s climate nuances, and we tailor each installation or replacement for optimal performance no matter the season.
Understanding What Your Home Really Needs
Choosing an air conditioning system isn’t just about picking the most powerful unit off the shelf. It’s about aligning your home’s characteristics with your lifestyle and comfort goals. Our expert technicians start with a thorough evaluation of your home’s size, layout, insulation, sunlight exposure, and existing infrastructure like ductwork. We also consider how you use different spaces — do you need to cool your entire home evenly, or would zoned cooling for specific rooms make more sense? With this detailed approach, we design customized cooling solutions that are efficient, effective, and built around your family’s day-to-day needs.
Exploring Your Air Conditioning Options in Mukilteo
No two homes are the same — nor should their cooling systems be. Here’s a helpful guide to the common air conditioning options we install and service:
- Central Air Conditioning Systems: Perfect for whole-home cooling, these systems use a network of ducts to distribute cool air evenly. If your home has existing ductwork and sufficient space, central AC offers consistent temperature control throughout every room.
- Ductless Mini-Split Systems: A flexible choice for homes without ductwork or for additions and remodels. They consist of an outdoor compressor and one or more indoor air handlers, each controlling the temperature of individual zones. Ductless AC units are praised for their quiet operation and energy efficiency.
- Window Air Conditioners: Ideal for cooling smaller spaces or single rooms on a budget. While they don’t have the efficiency or reach of central or ductless systems, they offer quick, convenient relief when needed.
Our team carefully reviews your home’s layout and your preferences to help you select a system that fits just right.
Finding the Right System for Your Space and Budget
Because comfort and value go hand in hand, we look at several critical factors to help you find the best unit:
- Energy Efficiency: Systems with high SEER ratings operate more efficiently, which can lower your monthly energy bills and reduce environmental impact.
- Home Size & Layout: Larger homes often benefit most from central AC, while smaller spaces or older homes without ducts might be better suited for ductless systems.
- Features & Technology: Modern AC units can come equipped with variable-speed motors, smart thermostats, and quiet modes — all designed to improve comfort and usability.
- Budget: Upfront installation costs vary, but a quality system installed professionally often saves money in the long run by avoiding costly repairs and keeping energy consumption in check.
At Gene Johnson Plumbing & Heating, we provide clear, honest advice so you can make an informed decision that suits both your comfort needs and your wallet.

Your air conditioning system is an investment that deserves to be cared for. Regular maintenance helps extend the lifespan of your system and keeps it running at top efficiency. Our maintenance services include:
- Filter and Coil Cleaning: Critical to maintaining airflow and cooling power.
- Refrigerant Level Checks: Ensuring your system isn’t leaking and is charged properly.

Knowing When It’s Time to Upgrade
No matter how well-maintained, air conditioning systems eventually age out. Signs it may be time to replace yours include:
- Increasing frequency of repairs.
- Rising energy bills without change in usage.
- Uneven cooling or current system failing to meet your comfort needs.
- System age over 10-15 years.
Replacing your AC can bring the latest efficiency technology, quieter operation, and smart home compatibility — making a huge difference in your comfort and convenience. Our team helps you weigh the costs and benefits, so you’re confident in moving forward.

Our technician arrived promptly the morning after we called, he figured out our problem in a short amount of time and then arranged to come out the next day and replace our failed pressure relief valve. We messaged our neighborhood WhatsApp group to see if others noticed increased water pressure. Hugo went above and beyond when he went to our neighbors to test their water pressures to see if they had issues. Some did. I’m sure it will lead to follow on work. He was courteous and efficient. We are happy with his work.
Stuart Webber
Great work, clear explanations, pleasant and courteous…very happy

We had Colby from Gene Johnson come out to estimate a gas line move for a kitchen remodel as well as a tankless water heater. He was professional (they wear shoe covers!), friendly and very honest about the requested services pricing and feasibility with a 100+ year old house. We haven’t chosen them for the actual work yet but most likely will given the experience. I will be sure to update my review when that happens!

Mike K was great. We’re in a new house, so Mike gave great advice on what to watch out for in a brand of toilet we’ve never used. Very friendly and walked me through all of our options to arrive at the best possible price.

Steven and Edgar were professional and timely – great communication as well. Would recommend!

Summary: Gene Johnson sent a tech (Matt Hunter) to address our home heating system, which was sending no heat at all to many rooms in the house. Our system is a wonky spaghetti mess of piping, controllers and pumps that theoretically delivers hot water to legacy cast iron radiators, new floorboard radiators, and seven in-floor hydronic loops. It has not worked as intended since we bought the house 15 years ago. It has likely *never worked right since the last house renovation 25 years go (2000), given the horrid “design” that was implemented then. Matt was the first tech ever to figure out how it all works. He repaired every failed component and problem that could be fixed, given our disastrous configuration. We are completely satisfied with Matt’s work and privately are enormously grateful that this money hole has now been tamed.
Our house dates to 1918, so challenges in upgrading the heating plant in 2000 were a certainty. However, the zoo in our HVAC room is nearly indecipherable. I have hired one HVAC company after another over last 15 years to make sense of it, at great expense.
Ninety percent of past techs gave incomplete explanations, proposed the replacement of a pump or controller, or the addition of a valve, and then left. Some were honest enough to simply offer a theory of how it works, while admitting they didn’t know, and then left us with a big bill.
Enter Matt Hunt. Not sure if Matt looks the part of genius plumber, but then I’ve never seen one till now. He’s a little nerdy perhaps (like me) and also a dirt bike racer. Whatever: Matt alone successfully unraveled the mysteries of our home hot-water distribution plant. He confirmed that the entire house is controlled by two thermostats, which are, incredibly, located just 16 feet apart on the first floor. (One controls all hot water distributed on the north side of the house; one controls all hot water sent to the south side. Go figure.) Matt explained why heat often doesn’t reach the upper floors even when the system is “working” (if it’s warm on the first floor, naturally, no heat is available to the second and third floors).
Matt discovered that the pressure in the water distribution lines was only 4PSI (target range: 13-22PSI), determined that the cause was huge amounts of air in the pipes, and the culprit was a broken refill valve. The new valve includes a pressure gauge so we can now see when the pressure in the water lines has fallen so low that the system can’t deliver hot water to the upper stories. He also spotted problems with the air eliminator, i.e. the “burping” component that normally should purge some/most of the air. He has proposed replacing that (agreed).
Matt drained the pipes on all floors; refilled the lines; purged all zones of air; and replaced the (broken) thermal expansion tank. Heat began to flow again to all rooms. He demosnttated that heat only happens on the upper floors provided that the two first-floor thermostats that control distribution to the entire home are below target temps and are calling for heat.
Matt mapped every radiator and hydronic zone to the main thermostat controlling it. He also determined which rooms/areas the hydronic thermostats control. (Of course, the hydronic thermostats, which are sprinkled around the house, are comic: they only perform as intended when the primary thermostats on the first floor are delivering hot water.) Matt gave us a detailed written explanation of what each component does and how it’s controlled.
Matt did all this in less time than some prior techs took to try and ultimately give up.
Our home heating system is a design wreck and will never deliver heat around the house reliably. However, with the fixes (and insights) mATT delivered, we now get heat when we want it with some work-arounds (like cooling down the first floor therostats). Further, we understand how to spot problems and fix the system going forward.
Thank you, Matt!

Steven came out to troubleshoot our tankless water heater and quickly identified the issue as a clogged condensate pump. What really stood out was the time he took to explain everything in detail. He walked me through the condition of the unit, the manufacturer’s recommended lifespan, and the condensation damage and rust that had already occurred due to the blockage.
Steven gave me honest, thoughtful guidance and helped me make an informed decision about replacing the unit, without any pressure whatsoever. He clearly explained that we could have gotten by with a descaling for now, but also helped me understand why replacing it would likely save money and headaches over the long run.
He was patient, knowledgeable, and answered all of my questions thoroughly. I really appreciated his transparency and professionalism, and I would absolutely recommend Steven and Gene Johnson to anyone needing plumbing or tankless water heater service. Thanks!
Casey Feaster
Very knowledgeable. Mike Keane really did an awesome job. Highly recommend these guys for all your plumbing needs. Definitely going to be a life long customer.

Joseph F came for a leak we were experiencing along with his partner and was beyond helpful. We have a 4 month old and also had a contractor there at the same time. He was kind enough to entertain our little one in his swing while my husband was moving some things in the bathroom and I was talking to the contractor. So unexpected and beyond the call they came out for. Thank you!
amy Wesner
