Air Conditioning Repair in Beaverton, OR

You’d be surprised how many things can go wrong with a cooling system—especially one that’s been cranking day and night. Whether your AC is relatively new or you’re nursing a unit that’s older than your dog, here are some of the most common air conditioning repair issues we fix in the Beaverton area:

Weak Airflow or Warm Air

If your AC is blowing warm air, it could be due to low refrigerant, a dirty evaporator coil, or a compressor issue. Poor airflow might point to a clogged air filter, blower motor failure, or issues with ductwork. We’ll zero in on the problem and restore that crisp, cool comfort.

Electrical Issues & Faulty Connections

Your HVAC system relies on dozens of electrical components—relays, capacitors, control boards, wiring. If just one fails, your AC unit might refuse to start or short cycle (constantly turning on and off). Our pros can test and repair every electrical connection safely and properly.

Frozen Evaporator Coils

Believe it or not, ice on your AC in the middle of summer is never a good sign. It usually means there’s an airflow issue, low refrigerant, or a dirty coil. We’ll thaw things out and make sure everything’s running efficiently again.

Strange Noises or Smells

Rattling, buzzing, banging, screeching… AC units can get noisy when parts are loose or breaking down. Weird smells could signal mold in the ductwork or a burned-out motor. Whatever it is, we’ll sniff it out and sort it out.

Thermostat Troubles

Sometimes the problem isn’t your AC at all—it’s the thermostat. If your home feels inconsistent or your system isn’t responding to commands, we’ll test the thermostat and recalibrate or replace it as needed.

We also tackle issues like clogged drain lines, air leakage in ducts, and malfunctioning heat pump components. No matter what’s going on, we’ll get your cooling system back on track with expert services tailored to your needs.

Low refrigerant is one of the top culprits behind weak or warm airflow, and if your AC is low, it likely means there’s a leak somewhere. Our trained technicians use specialized tools to locate and fix refrigerant leaks accurately—no guesswork involved. Once the leak is repaired, we refill your system with the proper refrigerant to manufacturer specifications.

We’ll also inspect the rest of your system for signs of wear and ensure everything is properly sealed and running at full capacity. Topping off refrigerant without fixing the leak is a temporary fix at best and can lead to costly repairs or compressor damage. That’s why we handle the entire process start to finish: detection, sealing, refilling, and testing for efficiency. When you call Sunset, you get the peace of mind knowing your refrigerant issues are handled the right way.

When you’re considering AC repair—or replacement—it’s smart to think about energy efficiency. Not only can a more efficient unit cool your home better, but it can also significantly lower your monthly energy bills.

One key number to understand is the SEER rating: Seasonal Energy Efficiency Ratio. This rating tells you how efficient your air conditioner is over an average cooling season. The higher the SEER rating, the more energy efficient the unit.

Most older systems operate with a SEER of 10 to 13. Today’s energy-efficient models often start at SEER 14 and go all the way up to 26 for top-of-the-line systems. If your current system is struggling and your energy bills are climbing, it might be time to consider an upgrade.

At Sunset, we’ll evaluate your current system’s performance and let you know if repair or replacement is the most cost-effective choice. And if you do opt for a new, energy efficient model, we’ll guide you through available rebates, tax credits, and financing options to make it affordable.

Whether you’re curious about SEER ratings, duct sealing, or how to improve your home’s overall energy efficiency, we’ve got answers—and we’re happy to walk you through it all.

Not every home in Beaverton uses a traditional central air conditioning system. If your home relies on ductless mini-splits or a versatile heat pump for year-round comfort, Sunset has you covered. These systems are efficient and flexible, but they still need occasional service and repair to stay at peak performance.

Whether your mini-split is struggling to cool like it used to, or your heat pump is short-cycling or making odd noises, our techs can diagnose and resolve the issue quickly. We know these systems inside and out and carry the right parts and tools to make repairs on the spot.

We also provide seasonal maintenance and performance evaluations for both ductless and heat pump systems, helping you keep them running smoothly and efficiently throughout the year. No matter what type of system keeps your Beaverton home comfortable, Sunset delivers fast, knowledgeable, and friendly service every time.

The best way to save money on air conditioning repairs? Don’t need them in the first place. Sounds obvious, right? But a little preventative maintenance goes a long way in keeping your system running efficiently and avoiding surprise breakdowns.

Here’s what we recommend:

Regular Maintenance

Schedule annual tune-ups to catch issues early. Our maintenance checks include cleaning coils, checking refrigerant levels, inspecting electrical components, replacing filters, and calibrating thermostats.

Seal Your Ductwork

Air leakage in duct systems is a major efficiency killer. We offer sealing ductwork services to improve performance and reduce wear on your unit.

Change Your Filters

Dirty filters restrict airflow and cause your system to work overtime. Set a reminder to change them every 1–3 months, depending on usage and air quality conditions.

Upgrade to Automated Technology

Smart thermostats can optimize your HVAC system and catch inconsistencies before they become problems. Plus, they help improve indoor air quality by maintaining stable temperatures and humidity levels.

Taking a few simple steps now can extend the life of your AC, lower energy bills, and reduce the need for frequent repair services.
