And when you come back to home base from a day out in the bright Florida sun, nothing ever feels better than relaxing at home with a central AC unit that keeps your home cool year-round.

You can trust the skilled team of HVAC professionals at Southern Air for AC replacement in Fleming Island, FL.

4 Signs It’s Time To Replace a Cooling and Heating System

It’s not uncommon for Fleming Island residents to proactively reach out and request new central AC systems because they want an energy-efficient upgrade or they’re building a new home. However, an AC unit is often replaced because something else is happening.

Here are four signs it might be time to replace your air conditioner system:

  1. Your unit is old. On average, air conditioners last about 10-20 years. If you have approached (or surpassed) that timeframe, it might be time to consider a replacement.
  2. Your unit requires frequent repairs. Those repair costs add up, and after a while, it might be time to stop throwing money at a system that’s near the end of its lifespan.
  3. Your unit doesn’t do a great job of cooling your home. If you’ve begun to notice that your house doesn’t feel as cool as it used to, or your air conditioner has to run longer to achieve a desired temperature, this could be a sign that your system isn’t capable of meeting your needs.
  4. Your energy bills are going up. While it’s normal for the costs of things to rise over time, a sudden spike in your energy bill without another explanation is cause for concern. An aging unit naturally becomes less energy-efficient, and you can potentially cut your utility bill by upgrading your AC unit.

How To Decide Between AC Repair and AC Replacement in Fleming Island

It’s not always an easy decision to choose between continuing to repair an aging AC system and replacing it with something brand-new. We can help you make a decision that’s based on your long-term goals, budget constraints, and the condition of your system as a whole.

When you request service and we visit your home, we can discuss the various options with you and weigh the pros and cons. While the age of your AC system is a key consideration, we will also help you evaluate future repair costs, energy efficiency issues, the current level of performance compared to your comfort levels, and even your home size.

Ultimately, we will look at your long-term goals to help you find a solution that works best for you!

We understand that choosing to go with a new AC installation is a significant financial undertaking, and we want you to be confident in your decision. We also offer financing options to make things easier on your wallet.

How Much Does it Cost to Replace an AC Unit in Fleming Island, FL

Replacing an AC unit in Fleming Island varies widely in cost, depending primarily on the unit’s size, type, and the specific requirements of the installation. On average, homeowners in Jacksonville can expect to pay several thousand dollars for a complete HVAC replacement for the unit and labor.

Factors that can influence the total cost include the brand of the AC system, its energy efficiency rating, and any necessary modifications to the home’s existing ductwork or infrastructure. Call us for an estimate of your AC replacement cost in Fleming Island.

Jamar braved the 102 degree heat, wasps who decided to make a nest hiding in my AC and the metal on the unit was hot! Jamar remained positive, friendly and happy to be doing my regular servicing of my AC. Southern Air knows how to pick their technicians. I have had remarkable service for over 7 years with Southern Air. Cannot recommend them any higher. I love having their annual service plan and you can budget with monthly payments. A++++++++

Jason was pleasant, professional and very straightforward. He showed us the very rusty and corroding coils and said we could keep repairing the 22 year old AC but it would be a waste of money and an ongoing and potentially hazardous decision. We are proceeding with a new AC based on his recommendation.
Response from the owner:We’re glad Jason was straightforward and helpful in walking you through the condition of your system. Thank you for trusting his recommendation—we look forward to getting your new AC installed and keeping your home comfortable.
