Air Conditioner Installation & Replacement Services

Choosing the right air conditioning system is just as important as choosing the company that installs it. At Semper Fi Heating & Cooling, we take the time to evaluate your home’s cooling needs before recommending a solution. Our goal is to install a system that delivers dependable performance, improves efficiency, and keeps your family comfortable for years to come.

New Air Conditioner Installation

Whether you’re building a new home or adding air conditioning to an existing property, our team installs properly sized systems designed to deliver consistent, efficient cooling throughout your home.

Air Conditioner Replacement

If your current system requires frequent AC repairs, struggles to maintain comfortable temperatures, or has become less efficient over time, replacing it may be the most cost-effective solution. We’ll remove your old equipment and install a new system that provides dependable performance and improved energy efficiency.

High-Efficiency Air Conditioning Systems

Modern air conditioners use less energy while providing better comfort than many older systems. We install high-efficiency equipment that can help lower monthly utility costs while maintaining reliable cooling during the hottest Las Vegas summers.

Professional System Sizing

An oversized or undersized air conditioner can lead to uneven temperatures, higher energy bills, and unnecessary wear on your equipment. Our technicians carefully evaluate your home’s size, layout, insulation, and cooling demands to recommend the right system for lasting performance.

Thermostat Upgrades

Installing a new air conditioner is a great opportunity to upgrade your thermostat. We install programmable and smart thermostats that give you greater control over your home’s comfort while helping improve overall system efficiency.

How To Know It’s Time for a New AC Unit

Replacing your air conditioner isn’t always an easy decision, but waiting too long can lead to higher energy bills, frequent breakdowns, and unreliable cooling when you need it most. If your system is more than 10 to 15 years old, struggles to maintain a comfortable temperature, runs constantly, or requires repeated repairs, investing in a new unit may be the more cost-effective option. Older systems also tend to be less energy efficient than today’s models, which means a replacement can improve comfort while reducing monthly utility costs. At Semper Fi Heating & Cooling, we’ll evaluate your current system, explain your options, and provide honest recommendations so you can make the best decision for your home and budget.

Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

They answered the phone on a holiday weekend, had a tech onsite in a few hours, brought in a temporary solution for the night and had people replacing the system the next day.

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.
