Air Conditioning Maintenance in Shoreline, WA
over 4659 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.

Steven and Joe did a great job for us today. Didn’t try and over charge us. Gave us quotes for all options. And then found out the problem was an easy fix and took care of it quickly.
VeenaM Arani
Excellent work by Andrew! He is very friendly and accommodating. Great job. Would recommend to others.
Lynnda Laurie
I wanted to invest in a tankless hot water heater. My current heater was still working, but I wanted the replacement done before it was an emergency. Colby gave me a bid that was significantly lower than a competitor. He and Hugo got the job done with such professionalism. They were both so pleasant and professional. I would hire them again in a heartbeat!
Kate Burdick
Had an external shower leak/hose and Gene J. sent someone out in just a few hrs. Rene Garcia was awesome, clear on (3) options (and prices) and got it working. Even drove up to Home Depot quickly to get the part. Thank you for excellent customer service!

2/11/26: Mark O. came out and did a thorough review of our plumbing system. The water heater was drained per the maintenance program. He also gave us pricing estimates on updating various components not up to the current standards. Mark is knowledgeable and personable — a pleasure to work with.
Bernie Kinimaka
Justin took care of our plumbing needs. Professional, clearly offered other service options as well. Thank you.

⭐️⭐️⭐️⭐️⭐️ Five-Star Review for Gene Johnson Plumbing
I cannot say enough good things about Mike K. Mike K spent hours here working extremely hard and never once gave up. He was literally sweating and did everything in his power to resolve a very difficult toilet clog. I have honestly never met a more honest, hardworking plumber than Mike K.
What stood out most was that he was determined to get the job taken care of today for Mike K — it was about doing the right thing. He thoroughly explained all the options, called his supervisors when he had questions, and approached everything with professionalism, integrity, and care. Mike K truly went above and beyond.
Because of Mike K’s incredible service, I will be using Gene Johnson Plumbing for the rest of my life. I will also be referring Gene Johnson to all of my friends, family, and colleagues without hesitation. This level of service is rare.
Mike K is not only an outstanding plumber, but a genuinely great person and an absolute asset to whatever team he is working on. He is the kind of professional you call and immediately know you are in good hands.
Thank you so much, Mike K, and thank you Gene Johnson Plumbing for employing such an exceptional individual. I cannot recommend you highly enough.

Great experience. Joseph was very professional and clearly an expert. He patiently answered all of my questions in depth and provided great insights.
Don Ripley
Noah visited our house for an emergency issue when our water heater failed and was severely leaking. Fortunately we caught before much damage was done. He had a prompt response on a Friday, clearly explained all our options, verified availability of all the necessary parts, removed and replaced everything same day… was amazing and greatly appreciated. He was very friendly and extremely professional throughout the entire process. Highly recommend!

Gene Johnson Plumbing has consistently demonstrated reliability, professionalism, and a genuine care for their craft and customers. Living in a home built in the early 1900s, I understand the importance of having a trustworthy plumber.
A special shoutout goes to the plumbers who have provided services in my home over the past six months to rectify previous plumbers’ mistakes.
Most recently, Andrew Bell Morgan stood out. He explained each step clearly, presented multiple options to solve the issue, considering cost, aesthetics, and potential savings. He ensured I understood the pros and cons of each option.
Hugo Lira Hernandez deserves another mention. He went above and beyond to provide clear access to my water shut-off valves, which were previously obstructed by various tubes and wires. It only took him a few minutes to untangle and secure the valves with a metal zip tie or two. This attention to detail, even though it took an extra minute, reflects his commitment to making things better for the future.

Sean was amazing with taylor plumping today.! He made sure all my concerns were taken care of. He was polite, professional and personable. So glad I work with Taylor heating and plumbing
J B
So happy I called these guys! Already did another review under my other email address but it’s worth repeating.
I had an estimate from a different company but ended up cancelling after being jerked around. Called BelRed and was able to set up three different appointments, todays being to look at and repair a leaky pipe. Something the other guys couldn’t find btw.
Anyway – Andrew came out, introduced himself, figured out where the leak was and quickly provided me an estimate as well as a timeframe for completion.
Work was done quickly, quietly and on time. Andrew had shown me pictures and videos of the before and also of the after and made sure to test the leak was fixed (and explained what happened and why).
It’s never easy spending money unexpectedly but helps when the company and the person who comes out to do the work gives a great first impression.

Noah Amini came to provide plumbing services for our sink. He was great! He took the time to explain why we had a problem and what he would be doing to correct it. He was very polite, professional, and nice. He gave tips on how to keep our pipes clean. I would ask for him again!
Also the woman customer assistant on the phone got someone to us the same day I called. Awesome!
Bert Han
Steven Fritz performed a plumbing inspection and also replaced the shut off valve and expansion vessel. He did a great job, very professional and friendly, answered all my questions.
Jef Iner
So happy I called these guys! Had called another plumber and felt super jerked around (cancelled my appointment). Made three separate appointments with BelRed, first visit to fix a leaky pipe. Andrew was great – quick, efficient, friendly and fixed the repair in the time quoted.
Tina Chin
Steven F. was excellent. He was knowledgeable, efficient, and quickly diagnosed and fixed our Navien tankless heater. He explained everything clearly and made the process easy. Highly recommend.
Jason Flynn
Chandler was great! He was courteous and knowledgeable. He also ran me through what he was doing. My shower handle is no longer difficult to turn and it works great!
Jessi Dabson
We had a FANTASTIC experience back in 2023 with Taylor Heating when our furnace decided to retire in the middle of winter. Not only were they only place out of 5 that actually answered their phone, they showed up fast, got us a quote that was very manageable, and got the work done fast. Flash forward to 2026, our water heater decided it was also ready to retire. (20 years for the furnace, and 23 for the water heater – not bad). We didn’t bother trying any other company. I sent in a request via the online form and had a phone call back and an appointment time scheduled within an hour.
Chandler was our tech on Wednesday – he is AWESOME!!! He is very personable, he answered all of our questions, and worked to help us get the best deal. He was able to replace the water heater the same day, so we didn’t have juggle a bunch of appointments – super fast and efficient. I HIGHLY RECOMMEND the Gene Johnson team to anyone looking for quality craftsmanship, manageable pricing, and top tier customer service.

Alex and Nick did a great job installing our new water heater. They worked diligently and efficiently, getting the work done in about 8 hours. They cleaned up well, you could barely tell they were here. Everything is in working order and the new system works great.
