Professional AC Replacement in Cary, NC

Most AC systems in the Triangle last 12 to 15 years. If yours is approaching that range, breaking down more than once a season, or struggling to keep your home below 78 degrees on a July afternoon, it's time to start planning a replacement rather than sinking more money into repairs. The math is straightforward: once a single repair costs more than half the price of a new system, replacement wins every time.

Age Alone Doesn't Tell the Whole Story

A 10-year-old system that's been well-maintained might have years left. A 7-year-old system that was sized wrong for the house might already be costing you hundreds extra per year. Our techs look at the full picture before recommending replacement — efficiency ratings, repair history, refrigerant type, and how well the system matches your home's square footage and ductwork.

That said, age does matter for one specific reason. If your system runs on R-22 Freon, you're on borrowed time. R-22 was phased out of production, and recharging costs have skyrocketed. We regularly see homeowners in Apex and Cary paying $150 to $300 per pound for R-22 top-offs on systems that are just going to leak again. At those prices, a new system with R-410A refrigerant pays for itself faster than most people expect.

Signs You're Getting Close to Replacement

Your energy bills keep climbing even though your habits haven't changed. That's your system losing efficiency, and no amount of maintenance brings it back past a certain point.

Your AC runs constantly but the house never feels comfortable. Short-cycling (turning on and off every few minutes) is equally bad. Both patterns mean the system can't do its job properly anymore.

You're hearing new sounds — grinding, banging, or squealing that wasn't there before. These usually point to failing motors or compressors, and those are the expensive components.

Uneven temperatures room to room. If your bedroom is 68 while the living room is 76, the system may be losing capacity or your ductwork has developed problems that a new installation can address.

Humidity inside feels worse than it should. A properly functioning AC removes moisture as it cools. When it stops doing that effectively, you notice it in the Triangle's summers.

What a Replacement Actually Involves

This isn't a quick swap. A proper AC replacement starts with a load calculation — a room-by-room measurement of your home's cooling needs based on square footage, insulation, window placement, and ductwork. Many homes in the Apex and Cary area that were built between 2000 and 2010 are now hitting that replacement window, and we often find that the original system was slightly undersized for the home or the ductwork has degraded over the past two decades.

Once we know the right size, we help you choose between efficiency tiers. A basic 14-SEER unit gets the job done. A 16 to 20-SEER system costs more upfront but cuts your cooling bills significantly over its lifetime. Duke Energy offers rebates for high-efficiency replacements, which helps close that gap. We walk you through the real numbers for your specific home so you can make a decision based on facts, not a sales pitch.

Installation typically takes one day for a straight replacement. If we're upgrading ductwork or switching refrigerant types, it may take a day and a half. Our crews are veteran-led and handle everything — removal, installation, refrigerant charging, thermostat setup, and a full system test before we leave.

The Cost Question

Nobody loves spending money on an AC system. That's why we offer a free replacement estimate so you know exactly what you're looking at before committing to anything. We also offer 0% financing so you can spread the cost over time instead of draining your savings in August.

Here's what most homeowners don't factor in: a new system typically saves $30 to $50 per month on energy bills compared to a 15-year-old unit. Over 10 to 15 years, that adds up to $3,600 to $9,000 — a real chunk of the replacement cost coming back to you through lower Duke Energy bills.

What Makes a Good Installation

The equipment matters, but the installation matters more. An oversized system short-cycles and creates humidity problems. An undersized one runs constantly and never catches up. Improper refrigerant charging — even slightly off — cuts efficiency by 5 to 15 percent and shortens the system's life.

Our techs are trained to get these details right. With over 700 five-star reviews from Triangle homeowners, we've built our reputation on doing the job correctly the first time. If your AC is aging out or racking up repair bills, give us a call for that free estimate. We'll tell you honestly whether it's time to replace or whether a repair still makes sense.
