Not every AC problem should be patched up. If your system is aging, constantly breaking down, or driving up your energy bills, a replacement could be the smarter — and more affordable — long-term choice. Plumb Pro+ provides expert AC replacements across the greater Charleston area with free estimates, financing options, and next-day installation.
Tell us about your system and we'll call you right back.
Sometimes the smarter move is a fresh start. Here are the most common signs our customers recognize before calling us for a replacement.
AC systems have an expected lifespan of 10–15 years. If yours is approaching or past that age, you're likely spending more on repairs and energy than a new system would cost.
If you're calling for repairs every season, the costs add up fast. A new system eliminates the cycle of surprise breakdowns and puts your budget back in control.
An aging, inefficient system works harder and harder to cool your home, driving up your electricity costs. Modern high-efficiency units can dramatically reduce what you pay.
Hot spots, uneven temperatures, or a system that runs constantly and never quite cools things down are signs the unit can no longer handle your home's demands.
R-22 (Freon) refrigerant was phased out in 2020 and is now extremely expensive to recharge. If your unit uses R-22, replacement with a modern system is almost always the right call.
When a compressor, heat exchanger, or other major component fails, the repair cost often rivals a new system. Replacement gives you a full warranty and years of reliable performance.
Every replacement is different, but our process is always the same — thorough, transparent, and done with respect for your home.
Our experts assess your property, existing ductwork, and cooling needs to recommend the properly sized, energy-efficient system for your home — at no cost and with no pressure.
On installation day, our NATE-certified technicians arrive prepared and respectful of your home. We remove your old system, install the new one, and leave your space as clean as we found it.
Before we leave, we thoroughly test your new system and walk you through how to operate it for peak efficiency. And we're always available for maintenance and support down the road.

"Our technicians were on time, efficient, hard-working, and thorough — spread drop cloths on floors and even vacuumed our carpet when completed. And the most polite work crew we have ever had. It was a HOT DAY in the attic, but they endured to replace our HVAC! Big THANK YOU to Mike, Zach, Sterling, & Pedro!!"
"Kyle was very pleasant and knowledgeable. He did not rush through the job. He was very upfront and took the time to explain the situation and made suggestions. It was a pleasure to have him in our home."
"I just had the very best experience with a plumbing service call. Kevin Hathaway with PLUMB PRO+ performed an excellent job repairing my water heater. He kept me posted on his progress, left his work area spotless, and carried himself in a professional manner. Thank you Kevin!"
