The Obvious Answer Isn't Always the Right One.

The problem may be the air conditioner or heat pump. It may also be airflow, ductwork, humidity, controls, or filtration. We diagnose the whole system before recommending anything.

Cooling

Air Conditioning Services in Jacksonville, FL

Air conditioning is one of the hardest working systems in a Jacksonville property. If your AC is blowing warm air, struggling to hold temperature, running constantly, making unusual noises, or not turning on at all, Mighty Air diagnoses the problem and recommends the right repair.

When an aging system makes replacement worth considering, we'll walk you through your repair and replacement options so you can decide what makes sense. Our Air Conditioning Services cover AC repair, maintenance, installation, and replacement throughout Jacksonville and Northeast Florida.

Heating Services in Jacksonville, FL

Florida winters are short, but you still want dependable heat when temperatures drop. For most Northeast Florida homes, that heat comes from a heat pump. Mighty Air's heating services focus on heat pumps, auxiliary and electric heat, thermostats and controls, airflow problems, and systems that are not heating the way they should. For homes that still use a gas furnace, Mighty Air also offers gas furnace replacement.

HVAC maintenance plans

HVAC Maintenance Plans

A Mighty Air maintenance visit is a real inspection of your system. We inspect the coils, check refrigerant performance, test electrical connections and components, check the condensate drain, and evaluate the thermostat, airflow, and overall condition of the equipment. Then we give you a straight report on what needs attention now, what can wait, and what is working fine. The Standard plan includes two seasonal visits a year and a 10% repair discount; Elite adds a 15% discount, no service call fee, and priority service. Both have a one-year commitment. See the full plan details, including pricing, benefits and limitations.

Hot and cold spots

Why Are Some Rooms Hotter Than Others?

Uneven temperatures are a common HVAC complaint, and replacing the equipment is not always the answer. Hot and cold spots can be related to any of these.

  • Airflow restrictions
  • Ductwork layout or condition
  • Closed or obstructed vents
  • HVAC system performance
  • Building design
  • Insulation or air leakage
  • Thermostat location
  • Sun exposure
  • Equipment sizing

Mighty Air looks beyond the thermostat and evaluates the HVAC system as a whole to find out why certain areas are hard to keep comfortable.

Repair or replace?

HVAC Repair or Replacement: Which Do I Need?

A system breakdown does not automatically mean you need new equipment. In many cases, a specific component can be repaired or replaced to restore operation.

What HVAC services does Mighty Air provide in Jacksonville?

Mighty Air provides AC repair and installation, heat pump and heating services, maintenance plans, duct cleaning and sealing, indoor air quality solutions, attic insulation, thermostat services, and HVAC parts replacement for residential and light commercial properties.

Do you service heat pumps?

Yes. Mighty Air repairs, maintains, installs, and replaces heat pumps throughout Jacksonville and Northeast Florida.

Why is my AC running but not cooling my house?

Possible causes include airflow restrictions, thermostat problems, refrigerant issues, dirty components, electrical or mechanical failures, and ductwork problems. A professional diagnosis finds the actual cause.

Why is my Jacksonville home so humid with the AC running?

Jacksonville naturally has high outdoor humidity. Indoor humidity can also be affected by how the HVAC system is operating, equipment performance, ventilation, and airflow. Excess humidity does not automatically mean you need a new air conditioner.

Should I repair or replace my HVAC system?

It depends on the system's age, condition, repair history, current problem, and the cost of repair compared with replacement. A professional diagnosis helps you compare both options.

What maintenance plans does Mighty Air offer?

Mighty Air offers two plans. The Standard and Elite Maintenance Plans both include two seasonal maintenance visits per year and a repair discount. See the full plan details for more.

Do you service both residential and commercial HVAC systems?

Yes. Mighty Air provides HVAC services for residential and light commercial properties in Jacksonville and surrounding areas.
