Signs You Need To Replace Your Commercial AC

Over time, your commercial air conditioner will likely show signs of major wear and tear. It’s important to be able to recognize these systems so that you can replace your AC before the unit fails.

You may need a new commercial AC unit if:

  • Your system isn’t producing cool air
  • Your unit smokes or sparks while in operation
  • Your AC doesn’t cool your property evenly
  • Your air conditioner hasn’t been replaced in over 15 years

Types of Commercial AC Systems We Replace

Commercial buildings rely on a variety of HVAC systems to maintain comfortable indoor temperatures and efficient climate control. We provide professional replacement services for many types of commercial air conditioning systems, helping businesses improve performance, energy efficiency, and reliability.

Rooftop Units (RTUs)

Rooftop units, also called RTUs, are one of the most popular commercial HVAC systems. Installed on the roof of a building, these packaged systems provide both heating and cooling, saving valuable indoor space. RTU replacement can improve energy efficiency, airflow, and overall system reliability for offices, retail stores, warehouses, and other commercial properties.

Split Commercial HVAC Systems

Commercial split systems use separate indoor and outdoor components to deliver cooling throughout a building. These systems are often found in smaller commercial spaces and can provide flexible installation options. Replacing an outdated split system can help reduce operating costs and improve comfort.

Variable Refrigerant Flow (VRF) Systems

VRF systems are designed for high-efficiency temperature control across multiple zones within a building. These advanced systems allow different areas to be heated or cooled independently, making them ideal for offices, hotels, and multi-use facilities. Upgrading a VRF system can enhance comfort while lowering your business’s energy consumption.

Ductless Mini Split Systems

Commercial ductless mini-split systems are often used in server rooms, additions, offices, and other areas where ductwork is impractical. These systems offer zoned comfort and efficient operation. Replacing older mini-split units can improve reliability and indoor air quality.

Chiller Systems

Chiller systems are commonly used in large commercial and industrial buildings to provide centralized cooling. Over time, aging chillers can become inefficient and costly to maintain. A new chiller system can improve cooling capacity, reduce downtime, and increase energy savings.

Packaged HVAC Units

Packaged HVAC systems combine heating and cooling components into a single cabinet. These systems are often used in commercial buildings with limited indoor mechanical space. Replacing an older packaged unit can provide better performance, quieter operation, and improved energy efficiency.

FAQs

Typically, air conditioning units will last for 10 to 15 years. With proper maintenance, they can last up to 20 years.

Replacing a commercial AC system can be a big project, but it is also well worth it. A new system will provide better energy efficiency, more consistent cooling, and peace of mind that a major breakdown is unlikely.

Signs that your commercial AC system may need replacement include rising energy costs, uneven cooling, frequent breakdowns, and aging equipment. Most commercial HVAC systems become less efficient over time, making replacement a more cost-effective long-term solution.

The cost of commercial AC replacement depends on factors like building size, system capacity, energy efficiency ratings, and installation complexity. A professional assessment can provide an accurate estimate based on your property’s cooling needs.

Commercial AC replacement timelines vary depending on the size of the system and the scope of the project. Many installations can be completed within a few days, while larger commercial properties may require additional time for setup and testing.

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
