Got Questions

Answers to Your AC Replacement Questions

Navigating air conditioning services in Jacksonville, FL, can raise many questions, especially when trying to ensure your home stays comfortable through our warmest seasons. At 365 Solutions, we’ve compiled the most frequently asked questions we receive about our air conditioning services, offering clear, concise answers to help you understand how we can meet your cooling needs.
How do I know if I need AC replacement or just a repair?

If your unit is over 10-15 years old, requires frequent repairs, or struggles to cool evenly, it might be time for AC replacement. We’ll assess your system and let you know if a repair or full replacement makes more sense.

What’s included in an AC system replacement?

Removal and disposal of the old equipment, the new condenser and air handler, a new pad or stand where needed, refrigerant line flush or replacement, a new thermostat if you want one, start-up and testing, and the manufacturer registration that activates the parts warranty. Most replacements are a one-day job. Parts and labor are guaranteed on every installation; the term depends on the equipment and is spelled out in your written price.

Can I upgrade parts of my AC system without replacing the whole thing?

Yes. Common AC upgrades include replacing a failing compressor or condenser, updating vents, or adding smart thermostat controls. These upgrades can extend system life and improve comfort

How much does it cost to replace an AC unit in St. Johns County?

In Northeast Florida a complete system replacement — outdoor condenser plus indoor air handler, installed — generally lands in the high four figures to low five figures. What moves the number: the size of the system (tonnage), the efficiency rating (SEER2), heat pump versus straight cooling, whether ductwork or the electrical needs work, and the brand. Rather than publish a price list, we measure your home, size the system properly and give you a written price before any work starts. Financing through GreenSky is available.

Do you replace AC compressors or just install new systems?

Yes, we offer compressor and condenser replacements for systems that are otherwise in good shape. Replacing just these components can restore performance without needing full system replacement.

Is it worth replacing my system with a central AC unit?

Central air offers better energy efficiency and quieter operation throughout your entire home, especially if you’re replacing window units, multiple ductless systems, or an older central unit. It’s often the best choice for homeowners who want a long-term, value-adding upgrade to their HVAC system.

What size AC unit do I need?

Not necessarily the same size as the one you have. Sizing depends on square footage, ceiling height, insulation, window exposure and how the house was built — a Manual J load calculation, not a rule of thumb. Oversized systems short-cycle and leave Florida humidity in the house; undersized ones never catch up in August. We size every replacement to the home, not to the old nameplate.

Is financing available for a new AC system?

Yes. 365 Solutions offers financing through GreenSky, LLC, subject to credit approval. GreenSky sets the rates and terms, not us, and you can apply once you have your written price in hand. Details are on our financing page.
