Not heating or cooling properly
The system runs but the house doesn't get where the thermostat says.
One System for Florida's Summers and Winters
Heat pumps are one of the most practical heating and cooling solutions for Northeast Florida homes and businesses. Unlike traditional air conditioning systems that only provide cooling, heat pumps provide both cooling during Florida's hot summers and heating during cooler weather.
Mighty Air provides professional heat pump repair, installation, replacement, and preventive maintenance throughout Jacksonville and surrounding Northeast Florida communities. Whether your system is not cooling, struggling to heat, or ready for replacement, our team can evaluate your equipment and help you understand your options.
Call Mighty Air, Inc. at (904) 292-0636 for heat pump service in Jacksonville.Florida winters are short, but they still get cold enough that a home needs heat. A heat pump handles both seasons with one system. In warm weather, it works like an air conditioner and moves heat out of your property. When temperatures drop, it reverses the process and brings heat inside.
Whether a heat pump is the right choice depends on your property, your existing HVAC setup, your comfort needs, and your budget. Mighty Air evaluates those factors and helps you compare your options.

Heat pumps behave differently from a standard air conditioner, so diagnosing them takes experience with how they actually run. We find the cause of the problem before recommending a repair or a replacement. Heat pump repairs we handle:
Some heat pump behavior surprises people. Air from the vents in heating mode can feel less hot than air from a furnace, and that's normal. A defrost cycle on a cool morning, sometimes with visible steam from the outdoor unit, is also normal. These are the signs that something needs attention.
The system runs but the house doesn't get where the thermostat says.
Cool air when it should be heating, or warm air when it should be cooling.
Auxiliary heat should only help on cold mornings and during defrost.
A defrost cycle should take care of it. Lingering ice is a problem.
Either one points to a system working harder than it should.
New sounds and weak airflow mean something has changed.
Instead of running only at full capacity, inverter-driven systems adjust to demand: more consistent temperatures, better humidity control, quieter operation. We'll help you compare technologies, efficiency ratings, comfort features, and installation requirements.
Not every heat pump problem requires new equipment. A failed capacitor, sensor, control, fan motor, or thermostat may be worth repairing when the rest of the system is in good condition.
For older equipment or systems needing frequent or increasingly expensive repairs, replacement may make more sense. We give you a clear picture of both options before you decide.
A heat pump has to be selected and installed to meet both the heating and cooling requirements of your property. A system that's too large or too small affects comfort, humidity control, cycling, and overall performance. Mighty Air evaluates your property and existing system before recommending equipment.

Because a heat pump heats and cools, it runs for much of the year in Northeast Florida. Seasonal inspections help catch airflow, electrical, refrigerant, drainage, and defrost problems before they turn into bigger repairs. Mighty Air's Standard and Elite maintenance plans include two seasonal maintenance visits a year and discounts on qualifying repairs.
Mighty Air services heat pumps for homes and light commercial properties throughout Jacksonville and Northeast Florida, including:
Rooms or additions where ductwork isn't practical can use a compatible ductless mini-split heat pump.

Quick answers to the questions Jacksonville homeowners ask us most about heat pumps.

Schedule Heat Pump ServiceYes. Heat pumps provide air conditioning during hot weather and heating during Florida's mild winters, all from one system. The equipment still needs to be properly sized for your property.
Yes. A heat pump moves heat out of your property to cool it, then reverses the process to heat it. Some systems also use auxiliary heat during colder conditions.
Both cool your home the same way. A heat pump can also reverse that process to provide heat, while a traditional air conditioner only cools and is usually paired with a separate heating source.
It depends on the system's age, condition, repair history, performance, and the cost of the current repair. We'll evaluate your equipment and help you compare both options.
For many properties, yes. Inverter heat pumps adjust their output to match demand, which may provide more consistent temperatures, better humidity control, and quieter operation. We'll help you compare inverter and standard systems for your property.
Auxiliary heat can turn on when the heat pump needs extra help, like on colder mornings or during a defrost cycle. If it runs constantly or much more than usual, the system should be inspected.
