AC Installation & Replacement in Hillsboro, OR

Oregon summers are getting warmer, and a cooling system that's undersized, inefficient, or poorly installed won't keep up. If you're adding air conditioning to your home for the first time or replacing a system that's reached the end of its life, the single most important decision you'll make isn't which brand to buy; it's which company installs it.

The day your AC is installed is the most critical day of its entire lifespan. A proper installation is what determines whether your system runs at the efficiency you paid for, lasts the 15 to 20 years it should, and stays under warranty. At O’Leary Air, we've spent years perfecting our installation work, and we back every job with a written guarantee. We don't just drop in a unit and leave it. We make sure everything is right before we go.

Call (503) 743-0417 to schedule your air conditioning installation and replacement services in Hillsboro, North Plains, Beaverton, Forest Grove, Portland, Vancouver, or the surrounding areas.

Is It Time for a New Air Conditioner?

Sometimes the signs are obvious. Other times you might be on the fence about whether to repair or replace. Here's what we look for when helping customers make that call:

• Your system is 10 to 15 years old. Air conditioners have a finite lifespan, and as they age they lose efficiency, require more refrigerant, and become harder to repair. If your system is in this age range and giving you trouble, replacement is usually the smarter long-term investment.
• Repair bills are adding up. One repair is normal. Two or three in a single season is a warning sign. When the cost of keeping an old system running starts approaching the cost of replacing it, a new unit almost always makes more financial sense.
• Your energy bills keep climbing. An aging or improperly sized system has to work harder to cool your home, and that inefficiency shows up on your utility bill every month. A modern, properly matched system can cut cooling costs significantly.
• The cooling is uneven or inadequate. If some rooms are comfortable and others feel like a sauna, the problem could be the system itself, its size, or how it's installed. We'll diagnose the real cause and recommend the right fix.
• The system is loud or running constantly. Unusual sounds and a unit that never seems to shut off are classic signs of mechanical wear or a system struggling to meet your home's demands.

What to Expect from Our Installation Process

O’Leary Air doesn’t believe in high-pressure in-home sales visits. Here's how our process actually works:

• First, we have a conversation, by phone or on-site, to understand your home, your current setup, and what you're looking for. For straightforward replacements, we can often give you a ballpark price range over the phone before we ever show up. For more complex installations, we'll come out, take measurements, and put together a detailed proposal.
• From there, you'll have everything you need to make a confident decision: a clear price, the equipment we're recommending and why, and the warranty terms in plain language. When you're ready to move forward, we schedule the work, show up when we say we will, and leave your home cleaner than we found it.

For a new installation in a home that's never had central AC, we assess your property’s square footage, insulation, ductwork, and existing HVAC setup to find the right system to meet your needs.

For a replacement, we evaluate your current system and existing infrastructure to determine the best match. One important note: we strongly recommend replacing your furnace or air handler at the same time as your AC unit whenever possible. A new condenser paired with an old air handler is like putting new tires on one side of the car; the mismatched components reduce efficiency and can void your warranty. We'll walk you through the pros and cons of both approaches so you can make the decision that's right for your budget.

The Equipment We Install

As a certified Daikin Comfort Pro dealer, we install the full Daikin lineup — including the innovative Daikin FIT inverter air conditioner, which uses variable-speed inverter technology to deliver precise, consistent cooling at significantly higher efficiency than conventional systems. Daikin equipment comes backed by a 12-year parts and labor warranty when installed by a certified dealer, which is among the best coverage in the industry.

We also install Goodman equipment, a dependable and budget-friendly option backed by a 10-year parts warranty.

Both lines offer a wide range of sizes and efficiency ratings, so we can match the right system to your home, your goals, and your budget — not just whatever's easiest for us to sell.

The O’Leary Air Air No-Risk Guarantee

When we install a new system, you're covered. Equipment comes with a parts warranty from the manufacturer, and we add our own labor guarantee on top of it: we cover all labor costs for up to 2 years after installation. That means for at least two full years, the only thing you should spend money on is routine maintenance. No surprise repair bills, no callbacks that cost you anything. We put that in writing.
