When Is It Time to Replace Your AC?
Many air conditioning problems can be corrected with professional AC repair. However, every cooling system eventually reaches the point where replacement becomes more cost-effective than continuing to pay for recurring repairs.
You may need to replace your air conditioner if you notice any of the following problems:
- Your AC system is more than 10 to 15 years old
- Frequent breakdowns or increasingly expensive repairs
- Rising monthly energy bills
- Uneven temperatures throughout your home
- Weak or inconsistent airflow
- Unusual noises or unpleasant odors
- Excessive humidity inside your home
- Your system uses outdated or difficult-to-source refrigerant
Our experienced technicians can evaluate your current system and help you compare the cost of repair with the long-term benefits of installing a new air conditioner.

Types of Air Conditioning Systems We Install
Every home has different cooling requirements. Our technicians install several types of air conditioning systems and will help you compare the advantages of each option.
Central Air Conditioning Systems
Central air conditioning is one of the most common cooling options for Florida homes. These systems use ductwork and vents to distribute cooled air throughout the house. We can replace your existing central air conditioner with a properly sized, energy-efficient system.
Ductless Mini-Split Systems
Ductless mini-split systems are an excellent option for homes without existing ductwork. They can also provide targeted cooling for home additions, garages, guest rooms, and areas that are difficult to keep comfortable.
Packaged Air Conditioning Systems
Packaged systems combine multiple HVAC components into a single outdoor unit. These systems can provide an efficient, space-saving cooling solution for certain homes and properties.
Our AC installation specialists will explain your options and help you choose the right new air conditioner for your home.
Our AC Replacement Process
We make replacing your air conditioner as straightforward as possible. The process begins with an in-home consultation and system evaluation. Our technicians assess your home, review your comfort concerns, and recommend properly sized equipment options.
We will also explain the cost to replace your AC system before work begins, including the equipment, installation requirements, and any available rebates or financing options.
Once you approve your new system, we schedule the installation at a convenient time. Our team removes the existing equipment, installs the new unit, tests the system, and ensures everything is functioning properly before completing the project.

AC Installation & Replacement FAQs
How do I know if I need AC repair or replacement?
If your air conditioner is less than 10 years old and only needs a minor repair, repairing it may be the better option. If the system is more than 10 to 15 years old, requires frequent repairs, or no longer cools your home efficiently, replacement may provide better long-term value.
How long does an AC replacement take?
Most standard residential AC replacements can be completed in one day. Larger or more complex projects may require additional time due to permitting, ductwork modifications, electrical work, or equipment availability.
What size AC unit do I need for my home?
The correct AC size depends on more than your home’s square footage. Insulation, windows, ceiling height, sun exposure, ductwork, and other factors can affect the proper system size. Our technicians perform a professional evaluation to recommend equipment that is appropriately sized for your home.
What happens if my new air conditioner is too large?
An oversized air conditioner may cool your home too quickly without running long enough to properly remove humidity. This can cause uneven temperatures, increased energy use, excessive indoor humidity, and unnecessary wear on the equipment.
What happens if my new air conditioner is too small?
An undersized air conditioner may run continuously while still struggling to maintain a comfortable temperature. This can increase energy bills and place excessive stress on the system.
What types of AC systems does CMi install?
We install central air conditioning systems, ductless mini-split systems, packaged HVAC units, and other residential cooling equipment. Our team will help you compare your options based on your home’s layout and comfort needs.
Do you offer financing for AC replacement?
Yes. Financing options are available with approved credit to help make your AC installation or replacement more manageable. Contact our team to learn more about current financing programs.
Are rebates available for a new air conditioner?
Manufacturer rebates, utility incentives, and other promotions may be available for qualifying systems. Our team will help you identify applicable savings when selecting your new equipment.
