Air Conditioning Maintenance in Shoreline, WA
over 4587 reviews
Shoreline summers might not hit triple digits often, but when the afternoons warm up and the air turns heavy, nothing beats stepping inside to a cool, comfortable home. The trouble is, that comfort doesn’t happen by accident. Air conditioners need consistent care to deliver reliable cooling, especially in our coastal climate, where salt air, moisture, and pollen can take a toll.
At Gene Johnson Plumbing, Heating, Cooling & Electrical, we’ve been serving Shoreline homeowners for decades. We understand the unique conditions your AC faces here, from spring debris clogging your outdoor unit to high humidity causing condensation issues. Our air conditioning maintenance services are designed to address these challenges head-on. We don’t just “check things over” — we clean, test, adjust, and fine-tune every part of your AC system so it runs efficiently and lasts longer.
Gene Johnson’s Shoreline AC Maintenance Checklist
Every AC system is a little different, but the principles of keeping them running well stay the same. Our technicians follow a thorough, step-by-step checklist that goes well beyond a quick visual inspection. Here’s what you can expect when you schedule your tune-up.
Air Filter Inspection and Service
A clogged filter is one of the most common reasons for reduced airflow and higher energy bills. In Shoreline, with our mix of coastal air and pollen season, filters can get dirty fast. We check your filter’s condition and replace it with a new one or clean it if it’s reusable. This simple step boosts airflow, reduces strain on the system, and helps improve indoor air quality.
Refrigerant Level Check
Refrigerant is what allows your AC to absorb heat indoors and release it outside. If levels are too low, your system works harder for less cooling. We measure the refrigerant pressure, add more if necessary, and inspect for leaks. Catching low refrigerant early can prevent major compressor damage.
Outdoor Coil and Cabinet Cleaning
Shoreline’s outdoor units can collect salt spray, pollen, dirt, and leaves that block airflow. We remove debris from around the condenser, clean the coils, and make sure nothing is restricting air movement. Clean coils help your AC release heat more efficiently, which means cooler air inside and lower energy bills.
Electrical System Inspection
Loose connections, frayed wires, or corroded terminals can cause intermittent operation or complete system failure. Our technicians check every connection, test voltage and amperage levels, and tighten or replace components as needed. This prevents dangerous electrical issues and ensures your system runs safely.
Motor and Bearing Lubrication
Any moving part in your AC — like the fan motor and blower bearings — will eventually wear down without lubrication. We apply the correct lubricant to reduce friction and noise, extending the lifespan of these components and keeping your system quieter.
Thermostat Calibration and Testing
Your thermostat is the brain of your HVAC system. If it’s off by even a few degrees, you could be wasting energy and sacrificing comfort. We check for accuracy, recalibrate if needed, and make sure it’s communicating properly with your AC system.
Condensate Drain Line Clearing
Moist air passing over the evaporator coil produces condensation, which should drain away. If the drain line is blocked, water can back up and cause leaks, mold, or even a system shutdown. We flush the line, ensure proper flow, and treat it to help prevent future clogs.
System Performance and Safety Check
We don’t finish until we’ve run your AC through a complete cooling cycle. We check start-up, operation, and shut-down performance, measure temperature differences, and verify that all safety controls are working as they should.
Our goal is simple: leave you with an AC system that runs efficiently, cools your home evenly, and is ready to handle Shoreline’s summer weather without any surprises.
Air Conditioning Maintenance FAQ
What’s the Difference Between a DIY AC Tune-Up and a Professional One?
DIY care is important, but it’s limited. Homeowners can change filters, clean around the outdoor unit, and adjust thermostat settings. A professional tune-up goes deeper — checking refrigerant, cleaning coils, testing electrical parts, lubricating motors, and calibrating controls. These tasks require training, tools, and safety checks to ensure your AC is truly in peak condition.
Which AC Maintenance Tasks Can I Handle Myself?
While a professional tune-up is essential for keeping your AC in top shape, there are a few simple tasks you can take care of yourself between visits. These quick checks and habits can help your system run more smoothly and avoid small problems from turning into bigger ones.
- Replace or clean the air filter regularly.
- Remove leaves, grass, and debris from around the outdoor unit.
- Keep vents and registers unblocked.
- Use a programmable thermostat to manage cooling schedules.
- Check for obvious signs of leaks or damage.
If you notice performance changes, strange noises, or leaks, it’s time to call a professional.
Can AC Maintenance Lower My Energy Bills?
Yes. Regular AC maintenance can noticeably reduce your energy bills by helping your system run more efficiently. When coils are clean, refrigerant levels are correct, and air filters are fresh, your AC doesn’t have to work as hard to reach your desired temperature. This means shorter run times and less electricity used.
A professional tune-up also ensures moving parts are lubricated, airflow is unobstructed, and the thermostat is calibrated for accurate control, all of which contribute to energy savings. Over time, the reduced strain on your system not only cuts utility costs but can also extend the life of your equipment. In many cases, the savings you see throughout the season can easily cover the cost of the maintenance visit.
What Minor Repairs Might Be Done During Maintenance?
During a maintenance visit, our technicians often handle quick fixes that keep your AC running smoothly and help avoid unexpected breakdowns. These small AC repairs are usually inexpensive but make a big difference in performance and reliability. Here are a few examples:
- Capacitor Replacement – A worn capacitor can prevent your system’s motors from starting properly. Replacing it keeps your AC running efficiently.
- Tightening Loose Electrical Connections – Secure connections prevent power loss, electrical arcing, and system malfunctions.
- Clearing Partially Blocked Condensate Drains – Ensures water from the cooling process drains correctly, preventing leaks and humidity problems.
- Thermostat Recalibration – Adjusts the thermostat so it reads and responds accurately, improving comfort and efficiency.
These small steps can prevent larger, more expensive issues later on.
Are Washable Filters a Good Option?
They can save money over time, but they often don’t trap as many fine particles as high-quality disposable filters. If you choose washable, clean them thoroughly and let them dry completely before reinstalling.
Is There a Best Time of Year for AC Maintenance in Shoreline?
Spring is the best time for AC maintenance in Shoreline because it prepares your system before the first warm days arrive. Servicing your AC early means we can spot and fix issues before you rely on it daily, ensuring it runs efficiently during the entire cooling season. You’ll also avoid the summer rush, when appointments fill up quickly. Even if you miss spring, it’s still beneficial to schedule maintenance before peak summer heat. A tuned system will use less energy, keep your home more comfortable, and reduce the risk of unexpected breakdowns when you need cooling the most.
How Often Should I Schedule Maintenance?
Once a year is recommended for most homes. If you have pets, allergies, or live near the water, twice a year may be beneficial.

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.

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.
Dana McKenzie
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
