Air Conditioning Repair | Hillsboro, OR
Is your air conditioning running constantly, yet your home never quite reaches a comfortable temperature? It’s time to consult with an AC repair professional for a thorough inspection. Columbia Heating & Cooling delivers expert AC repairs and tune-ups throughout Hillsboro to keep you comfortable all season long. Don’t let the heat get the best of you!
Numerous issues can compromise your air conditioner’s ability to maintain the ideal temperature in your home. You might be dealing with a faulty thermostat that sets the temperature far too low, or perhaps it keeps things too warm, making your indoor space feel as hot as a sweltering Hillsboro afternoon in July.
Getting your air conditioner repaired promptly is essential for maintaining comfortable indoor temperatures, the best indoor air quality, and maximizing energy efficiency. When you reach out to the experts at Columbia Heating & Cooling for an air conditioning repair in Hillsboro, OR, you can count on us to deliver all of these benefits and beyond.
We’ll also provide honest guidance about whether repairing your AC makes sense or if investing in a new air conditioner would be more practical, particularly if your system is aging and experiencing frequent breakdowns. (Even the most reliable air conditioner has a limited lifespan. Pouring money into repairs for a 20-year-old unit that continues to malfunction may not be the wisest investment.)
What are the consequences of ignoring AC problems and leaving them unaddressed? Your system could fail completely, leading to a total breakdown or ongoing performance issues. Eventually, replacement becomes inevitable anyway, and that can end up costing significantly more than timely repairs.

We’ve been serving the Hillsboro area for years and take pride in restoring your cooling system to optimal performance.

When to Get Your Air Conditioner Repaired
Signs You Need an AC Repair
Repairing an air conditioner is typically worthwhile in most situations, especially when your AC system is relatively new and this is the first time it’s showing signs of trouble.
How do you know if you need an AC repair in Hillsboro? Watch for these warning signs:
#1: Leaks
Air conditioners can develop various types of leaks, including water or refrigerant. When you spot water leaking from your AC, the likely culprits are a blocked drain line or problems with your pump or pan.
Refrigerant leaks pose a much greater risk than water leaks, and distinguishing between them isn’t always straightforward. Refrigerant leaks commonly occur in the accumulator, condensing coil, evaporator coil, or suction line dryer.
#2: Airflow Restrictions
When your AC isn’t delivering adequate airflow, a repair can often resolve the problem. (We can also identify airflow issues during regular maintenance visits.) Airflow problems frequently stem from obstructions in your condenser unit or vents, or from a clogged filter.
Before contacting your local Hillsboro air conditioning repair team, try replacing your filter to see if that solves the issue. (Along with thermostat problems, this ranks among the most frequent AC issues.) Your filter serves as a barrier that keeps dirt and debris out of your air and ductwork. When a filter hasn’t been replaced recently, it can restrict airflow and cause your home to feel warm, stale, and unpleasant.
#3: Loud and Strange Noises
Hearing your AC’s motor is perfectly normal. However, be alert for other sounds, particularly grinding, grating, or squealing noises. Squealing and similar sounds often indicate that your outdoor fan motors and indoor blower motors require repair or replacement. Our HVAC professionals will also inspect your blower wheel.
Delaying these repairs increases the likelihood that you’ll need to replace your AC entirely rather than simply fixing it. Remember that consistency matters. If your air conditioner produces unusual sounds immediately after installation, that might be normal. If the noises persist, it’s likely a repair issue. Reach out to a Hillsboro HVAC repair technician if you’re unsure.
#4: Hot Air and Humidity
When your air conditioner seems to be increasing humidity rather than controlling it, repairs are probably necessary. At Columbia Heating & Cooling, we’ll start by confirming the equipment is properly sized for your home.
Next, we’ll assess the thermostat and other components of the air conditioning system to identify what’s causing the excess humidity. When you work with us, you’ll have confidence that skilled experts are handling the job and will restore your air conditioning unit to proper function quickly. We can also address issues with your AC blowing hot air instead of cold.
#5: Smells
Is your air conditioner giving off an odor like paint thinner or something equally unusual? Perhaps it’s producing a sweet smell, and you’re certain there’s nothing cooking that could explain it. Both of these odors can signal that your AC is leaking refrigerant, which poses a health risk to you and your family and requires immediate attention from an HVAC professional.
Additional smells that suggest problems with your air conditioner include mildew, vinegar, or ammonia. If you detect any of these unusual odors when your AC is running, a repair is likely needed.

How to Fix an AC That’s Not Cooling
Know What to Do If It Happens to You
Air conditioners deliver cool air and create a comfortable environment for you and your loved ones. If your home remains warm even after adjusting the air conditioning unit, inspect the ducts. If they’ve become disconnected, or one has sustained damage, that could explain your cooling problems.
You may also need to replenish refrigerant levels. Declining refrigerant could indicate a leak in your unit. If this leak is accompanied by unusual or loud sounds (e.g., hissing), contact an air conditioning repair technician in Hillsboro (like your local Columbia Heating & Cooling) immediately.
The most effective way to fix an AC that’s not cooling or experiencing other problems is to call in the professionals. It’s also crucial to maintain your AC at home when possible by changing the filter every one to three months, cleaning the coils, monitoring the ducts, and scheduling an AC tune-up annually with an HVAC technician (preferably in the spring).
If your AC continues to fail at cooling your home, regardless of what you try, please don’t hesitate to reach out to us. Our air conditioner repair company has an excellent track record and would be happy to diagnose your cooling issues (and resolve them!).
