Ductless Mini Split Services

Common Problems We Fix:

Not Cooling

Your unit runs but the room stays warm. We check refrigerant levels, clean dirty coils, and diagnose compressor or sensor issues same day.

Blowing Warm Air

Usually points to low refrigerant, a dirty filter, or a reversing valve issue. We diagnose the cause and fix it fast.

Water Leaking from Indoor Unit

Almost always a clogged condensate drain or frozen coil. We clear the drain, check airflow, and confirm it’s draining correctly before we leave.

Error Codes

We read and diagnose all manufacturer error codes and explain exactly what they mean before doing any work.

Making Noise

Rattling, clicking, or grinding usually means a loose component, dirty blower wheel, or failing fan motor. We find the source and fix it.

Not Heating

We check the reversing valve, refrigerant charge, and defrost cycle to restore heat quickly.

Don’t see your problem? Call us and we’ll figure it out.

What Does Service Cost?

Mini split costs vary based on the service needed. Here’s what most jobs cost in Jacksonville:

Single-zone installation: $1,500 to $4,500 depending on system size, brand, and installation complexity
Multi-zone installation: $3,500 to $10,000+ depending on number of zones and system size
Common repairs: $150 to $800 for most diagnostic and repair visits

Annual maintenance tune-up: $69.50 (keeps the system efficient and catches problems early)

You get upfront pricing before we start any work. We confirm the full cost before anything gets touched.

Is a Ductless Mini Split Right for Your Home?

A Mini Split Makes Sense When:

You have a room addition, garage, or sunroom without existing ductwork
Your home has no duct system and adding one would be too costly or disruptive
You want independent temperature control in specific rooms
You want to supplement a central AC system that struggles in certain areas
You’re converting an attic, basement, or bonus room into livable space
You want a highly energy-efficient system with no duct losses

Central AC May Be a Better Fit When:

You need to cool the entire home and existing ductwork is in good condition
Your budget favors a single system over multiple indoor units
You prefer a single thermostat controlling the whole home

Frequently Asked Questions

What's the Most Common Problem We See?

Dirty or clogged filters are the most common issue we see. Florida’s year-round runtime speeds up buildup in mini split air handlers faster than most homeowners expect. Cleaning or replacing filters every 2 to 4 weeks prevents most performance problems.

Can You Repair an Older Mini Split System?

Yes in most cases. However, finding parts for older mini split units can be difficult and expensive. We’ll always let you know if repair makes sense or if replacement is the better investment.

Do You Charge a Diagnostic Fee?

Yes. We charge a $69.50 diagnostic fee for the service call. We waive that fee if you proceed with the recommended repair. You’ll know the total cost before we start any work.

How Quickly Can You Come Fix My Mini Split?

We offer same-day service when you call before 2 PM. Emergency service is available 24/7 for urgent situations. Most calls are responded to within 2 to 4 hours.

How Long Do Mini Split Repairs Take?

Most repairs finish in 1 to 3 hours. Simple fixes like filter cleaning or drain clearing take 30 to 60 minutes. Complex repairs may need a return visit if we have to order special parts.

How Can I Prevent Mini Split Breakdowns?

Clean your filters every 2 to 4 weeks, keep the outdoor condenser unit clear of debris, and schedule a maintenance visit once a year before cooling season starts. Those three habits prevent the majority of breakdowns we see.

What If My Mini Split Can't Be Repaired?

If your mini split is beyond economical repair, we’ll explain your options honestly. We offer financing on new mini split installations and can usually install a replacement system within 1 to 2 days. Our team will help you choose the right size and efficiency level for your home and budget.

Are Your Repairs Guaranteed?

Yes. All repairs come with our workmanship warranty. Parts warranties vary by manufacturer. We’ll walk you through what’s covered before we start any work.
