Our Air Conditioning Repair Process in Lake Oswego
Here’s how we approach every AC repair job with the skill, care, and attention to detail we’ve built our name on:
1. Thorough Inspection & Diagnostics
We begin with a complete evaluation of your HVAC system. This includes checking refrigerant levels, airflow output, thermostat function, electrical components, filters, condensers, coils, and ductwork. We also listen closely to any noises or symptoms you’ve observed.
2. Clear Communication
After the diagnosis, your technician will walk you through their findings in plain language. We’ll explain whether a simple repair or a more complex solution is needed, and we’ll provide free estimates before any work begins. No pressure, no upsells—just honest recommendations that make sense for your home and budget.
3. Quality Repairs, Done Right
From replacing a faulty capacitor to correcting refrigerant leaks or addressing electrical issues, we use the highest-quality tools and replacement parts available. We follow industry best practices and ensure everything is installed, calibrated, and tested for peak performance.
4. Clean Workmanship & Respect for Your Home
We treat your home as if it were our own. That means wearing shoe covers, protecting your floors, cleaning up after ourselves, and always showing respect for your property and your time.
5. Final System Testing & Optimization
Once the repair is complete, we perform a series of post-repair checks to make sure everything is working properly, including airflow and temperature readings, electrical safety checks, and a full inspection of your ductwork and thermostat settings.

What Are the Most Common AC Problems We Fix for Lake Oswego Homeowners?
Even the most well-maintained cooling systems can encounter hiccups—especially during the summer season when they’re working overtime. Here are some of the most common AC issues we see during our service calls in Lake Oswego:
Frozen Evaporator Coils
If your unit is freezing up, it could be due to poor airflow, a clogged filter, or refrigerant issues. This usually presents as low cooling output and visible ice buildup.
Refrigerant Leaks
Low refrigerant levels due to leaks make it impossible for your AC to effectively cool your home. This can lead to high energy bills and permanent damage to the compressor if not addressed.
Faulty Electrical Components
From worn-out capacitors to malfunctioning relays or corroded terminals, electrical problems are a frequent culprit in system shutdowns and erratic behavior.
Dirty Condenser Coils
When condenser coils are covered in grime and debris, your system has to work harder to expel heat—reducing energy efficiency and increasing the risk of overheating.
Blower Motor Failures
If certain rooms aren’t getting airflow or you hear a loud hum or rattle, it could be the blower motor, which is responsible for pushing cool air through your home’s ductwork.
Duct Leaks or Blockages
Leaky or blocked air ducts mean your cooled air isn’t reaching its destination, causing uneven temperatures and high utility costs. Our team can also help with duct sealing and duct cleaning to improve performance and indoor air quality.
How Do I Know My Air Conditioner Needs Repairs?
Sometimes it’s clear you need help, like when your AC won’t turn on at all. But other times, the signs are more subtle. Call Sunset Heating, Cooling, Electrical & Plumbing if you notice any of the following:
🧊 Blowing warm or lukewarm air
💨 Weak or inconsistent airflow from vents
🔊 Unusual noises—grinding, squealing, rattling
💧 Moisture or water pooling around the unit
🌡️ Frequent short cycling (turning on and off rapidly)
🌪️ Bad smells—burning, musty, or mildew odors
💡 Spikes in energy bills without increased usage
🚨 Thermostat not responding or inaccurate readings
Early intervention helps prevent more serious damage and keeps repair costs down.
Is It Better to Repair or Replace Your AC?
Sometimes, a repair is all you need. Other times, especially if your air conditioner is more than 10–15 years old, it might be time to consider a new air conditioning installation.
Here’s when replacement may be your best bet:
🔧 Multiple breakdowns in a single season
📆 Unit is over 12–15 years old
💸 Repairs cost more than 50% of replacement
🌡️ Inconsistent or inadequate cooling
⚡ Poor energy efficiency (low SEER rating)
🛑 Refrigerant type is outdated (like R-22)
We’ll provide a detailed comparison and free estimate for replacement if needed, including energy-efficient systems with high SEER ratings and heat pump options for year-round comfort.
Do You Repair and Services Ductless Mini-Split Air Conditioners?
Yes! We’re fully equipped to handle ductless mini-split repair, maintenance, and installation. These systems are a great fit for older homes, additions, or zones with unique cooling needs. We’ll ensure your ductless setup is quiet, clean, and efficient.
How Long Does a Typical AC Repair Take?
Most air conditioning repairs can be completed in 2–4 hours depending on the issue and part availability. We aim to diagnose and fix the problem during a single service call whenever possible.
Are There Rebates or Tax Credits Available for Energy-Efficient AC Units?
Yes! Depending on the system you choose and current local and federal programs, you may be eligible for rebates or tax credits. As a certified contractor, we stay up to date on the latest incentives and will help you maximize your savings.
How Often Should I Schedule AC Maintenance?
We recommend regular AC maintenance at least once a year—preferably in spring before peak cooling season. This keeps your system running efficiently, helps prevent breakdowns, and may even be required to maintain your manufacturer’s warranty.
