Air Conditioning Maintenance in Shoreline, WA

over 3,900 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.

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.
