Reliable Rooftop HVAC Replacement Las Vegas
We replace aging rooftop units fast to improve comfort, lower energy costs, and reduce costly breakdowns.
Rooftop HVAC Replacement Las Vegas
When a rooftop unit starts failing, energy bills climb, airflow gets worse, and comfort becomes hard to control. At AC Captain, we replace old rooftop HVAC systems for Las Vegas homes, retail spaces, offices, and light commercial buildings with a focus on long-term performance. Our goal is simple: give you a dependable heating and cooling system that can handle extreme desert heat without wasting energy.
Rooftop HVAC replacement is more than swapping one unit for another. We inspect the existing package unit, roof curb, duct connections, electrical components, thermostat controls, and overall system sizing. If a unit is too small, too large, or badly worn out, it can cause short cycling, hot and cold spots, higher utility costs, and repeated repairs. We help you choose the right replacement based on your building size, usage, airflow needs, and efficiency goals.
Our service covers removal of the old rooftop unit, safe handling of equipment, installation of the new RTU, reconnection of ductwork and power, and full system testing. We also check refrigerant charge, airflow, drainage, and thermostat operation to make sure the new system runs the way it should from day one. If needed, we can address issues such as damaged curbs, poor duct sealing, and worn connections that may affect performance.
We install quality rooftop heating and cooling systems designed for durability, better indoor comfort, and improved energy efficiency. A properly installed replacement can help lower repair frequency, improve temperature control, reduce strain on system components, and extend the life of your HVAC investment. For many property owners in Las Vegas, replacing an aging rooftop AC unit before a full breakdown also helps avoid downtime during the hottest part of the year.
Since 2015, we have built AC Captain around quick response, honest recommendations, and reliable workmanship. We understand how important it is to keep your property comfortable and your business or household running normally. If your rooftop unit is noisy, unreliable, inefficient, or near the end of its service life, we are ready to help. Contact AC Captain today to schedule a rooftop HVAC replacement evaluation in Las Vegas and get a system that is built to perform when you need it most.
Our Rooftop HVAC Replacement Process
We make rooftop HVAC replacement in Las Vegas simple, organized, and stress-free. From the first inspection to final startup, we focus on safety, efficiency, clear communication, and long-term comfort for your property.
On-Site Evaluation & Replacement Plan
We start with a rooftop system inspection, load check, and site review to confirm equipment size, curb fit, duct connections, power needs, and access for crane service if needed. Then we give you a clear replacement plan, timeline, and upfront estimate built for your building and budget.
Permits, Scheduling & Job Prep
Once you approve the project, we handle scheduling, equipment ordering, and job planning so the replacement stays on track with minimal disruption. We coordinate delivery, rooftop access, and code-related details, while keeping you updated on timing, what to expect, and how we protect your property during the work.
Installation, Startup & Final Walkthrough
Our crew removes the old rooftop unit, sets the new system, completes electrical and duct connections, and tests airflow, refrigerant charge, controls, and overall performance. Before we wrap up, we walk you through the work, answer questions, and make sure your new unit is running reliably and efficiently.

"My AC went out and my home warranty AHS denied my claim due to reason is electrical. The tech they sent diagnosed power surge caused damage to unit. Recommended $12K to replace. I called around and found several but they all charge service fee. Called A/C captain and then a technician Gerardo. He was very thorough in diagnosing the issue, explaining patiently and did some tests. He gave me two options: repair or replace but he didn't emphasize the replace option. I opted to fix, they ordered the part and came the even though it was already late. Gerardo worked through the dark and windy weather , finished, tested and everything worked. Thank you A/C captain for a skilled technician."
