over 4690 reviews
Is your AC blowing warm air when it should be cool? Or maybe it’s making a weird noise and turning off at random times? When your home starts feeling more like an oven than a retreat from the heat, you know something’s off—and fast action can make all the difference.
At Gene Johnson Plumbing, Heating, Cooling & Electrical, we’ve been handling air conditioning repair and other air conditioning services for Bothell homeowners and businesses for decades. Whether it’s a small part on the fritz or a larger problem in the HVAC system, our licensed Bothell technicians are here to fix it. No guesswork. No unnecessary upsells. Just honest, professional AC repair services designed to restore your comfort—and help prevent future breakdowns.
The Most Common AC Repairs We Deal With in Bothell, WA
We’ve seen it all—from rattling fans to systems that just won’t turn on. Below are some of the most common issues we fix in homes and businesses throughout Bothell.
Low Refrigerant Levels
When your AC isn’t cooling well, low refrigerant is often the culprit. It can be caused by a leak somewhere in the system—often due to worn-out lines or connections. Our team will locate the leak, seal it, and recharge the refrigerant so your system can cool effectively again. Left unaddressed, it can cause major strain on the compressor.
Frozen Evaporator Coils
Poor airflow, clogged filters, or low refrigerant levels can cause coils to freeze up. You’ll notice weak or no airflow coming through your vents. We’ll inspect your filter, blower motor, and airflow paths, defrost the coil, and make sure the system is balanced so it won’t happen again.
Dirty or Blocked Condenser Unit
The outdoor condenser needs room to breathe. If it’s packed with debris, leaves, or dirt, it can overheat. That leads to cooling issues, higher energy bills, and even AC shutdowns. We clean the condenser, check the fan, and clear away anything that’s blocking proper ventilation.
Faulty Capacitors
Your AC unit’s motors rely on capacitors to start and stay running. When a capacitor fails, the fan or compressor won’t kick on. We carry high-quality replacement parts on every service vehicle and can swap it out quickly to get you back up and running.
Thermostat Issues
Sometimes the problem isn’t your AC at all—it’s the thermostat. Bad wiring, low batteries, or incorrect thermostat calibration can make your system behave erratically. We test the unit, recalibrate or replace it if needed, and ensure it’s synced with your HVAC system.
Clogged Drain Line
All that condensation your AC produces has to drain somewhere. If the drain line gets clogged, it can back up and cause water damage. We flush out the line, clear any blockages, and check for overflow safety switches to keep things dry.
Blower Motor Failures
If you’re hearing a humming noise but no air is moving through your vents, your blower motor could be to blame. Sometimes it just needs cleaning or a new capacitor. Other times, it needs a full replacement. We diagnose the issue and explain your options clearly.
Compressor Problems
The compressor does the heavy lifting in your air conditioner. If it fails, your system may turn on but won’t cool. Compressor replacement is one of the more serious repairs, and we’ll walk you through whether it’s better to fix or consider an AC replacement based on the unit’s age and condition.
Ductwork Leaks
Leaky or disconnected ducts mean your cooled air escapes before it ever reaches your living spaces. That not only makes your home uncomfortable—it drives up your energy bills. We offer full ductwork repair and duct sealing to restore proper airflow.
Whatever the issue, Gene Johnson’s HVAC repair team is here to help Bothell homeowners stay cool and comfortable year-round.
The Main Tell-Tale Signs Your AC Needs Professional Repairs
Not sure if you need a repair call yet? Keep an eye out for these common warning signs:
- Warm air coming from vents
- Little or no airflow
- Short cycling (frequent on/off)
- Unusual noises—grinding, hissing, or banging
- Higher than normal energy bills
- Water pooling near your AC unit
- Musty or burnt smells when running
If any of these sound familiar, don’t wait—addressing them early can save you from a major breakdown later.
Is There Any Troubleshooting for an AC Unit That’s Not Cooling?
Yes, there are a few things you can check before calling us:
- Make sure your thermostat is set to “cool” and the temperature is set below the current room temp
- Replace a dirty or clogged air filter
- Inspect the outdoor unit for blockages (like leaves or dirt buildup)
- Check your breaker panel for a tripped circuit
When to Call a Pro
If those steps don’t resolve the issue—or if you hear strange noises, see ice forming on the coils, or the system still isn’t blowing cool air—it’s time to call a licensed HVAC technician. Electrical components, refrigerant lines, and compressors are not DIY-friendly, and improper handling can lead to costly repairs or injury.
If your quick checks don’t bring relief, we’ll take it from there. We’re always happy to troubleshoot with you over the phone, too.
Why Is My Air Conditioner Short-Cycling?
Short cycling—when your AC turns on and off every few minutes—puts a huge strain on your system. Here are some common causes:
Oversized AC Unit
If your AC unit is too big for your home, it cools the space too quickly, then shuts off—over and over. We can evaluate your system’s size and recommend a better fit if needed.
Dirty Air Filter
A clogged filter restricts airflow, which can cause your system to overheat and shut off early. Changing your filter is a quick and inexpensive fix.
Low Refrigerant
Low refrigerant levels throw your system out of balance. The compressor may overheat and shut down too soon. We’ll find and fix the leak before recharging the system.
Thermostat Problems
Incorrect thermostat placement or faulty wiring can trick your system into thinking it’s cooler than it is. We’ll check placement and calibration.
Electrical Issues
Faulty capacitors or relays can interrupt your system’s cycles. We’ll test the electrical components and replace them as needed.
Short cycling wears out your system fast—if it’s happening, don’t wait too long to schedule an inspection.
What Is the Cheapest and the Most Expensive AC Repair in Bothell, WA?
The most affordable AC repairs are typically things like thermostat replacements or capacitor swaps. These usually run between $150 and $300 and can often be completed in under an hour.
On the other end of the spectrum, the most expensive repairs usually involve compressor replacement, major blower motor issues, or significant refrigerant leaks. These repairs may cost $800 or more, depending on parts, labor, and system type. In some cases—especially with older AC systems—replacing the unit entirely might be the more cost-effective and energy-efficient route. We’ll always provide transparent pricing and help you weigh repair vs. replacement options if you’re facing a costly fix.
Can an Old Thermostat Ruin My Air Conditioner?
It definitely can cause trouble. An outdated or malfunctioning thermostat can send bad signals to your AC system, causing it to run too long, turn off too soon, or not come on at all. Miscommunication can cause short cycling, overheating, or uneven cooling. If your thermostat isn’t calibrated correctly, it might keep your system running longer than necessary, which stresses components and hikes up your energy bills. Older models may also lack the sensitivity to accurately maintain a set temperature. Replacing it with a modern, programmable thermostat can improve comfort, efficiency, and system performance overall.
Can Regular AC Maintenance Prevent AC Repairs?
Absolutely. Regular air conditioning maintenance helps catch small issues before they snowball into expensive repairs. It also keeps your system running more efficiently, which can lower your monthly energy bills. During a tune-up, our HVAC technicians check for worn parts, clean coils, test safety switches, inspect refrigerant levels, and ensure everything is calibrated properly. That means fewer breakdowns, better indoor air quality, and a longer lifespan for your AC system.

Called to get leaky water tank replaced. The team sent Jeff over and performed way above any expectation… He is a great tech but mostly a wonderful human being. He was clear and complete in his communications. Helpful and thoughtful the whole way through. Great guy! His knowledge and professionalism shines in what he does, and does well. I have his card and will not ever hesitate to reach out, for anything that may come up in the future. Jeff leads in representing what I like to call “old school” approach to customer service and managing any task or service he provides, from simple to complex. You got a winner there, for sure!
