Heating Repair, Installation and Maintenance From a Family-Owned Local Team
Although Northeast Florida is known for warm weather, dependable heating is still important when temperatures drop. Mighty Air provides professional heating repair, installation, replacement, and preventive maintenance for residential and light commercial properties throughout Jacksonville and surrounding communities.
Our technicians work with heat pumps, electric heating components, thermostats, and compatible HVAC systems to help customers maintain comfort throughout the year.
Call Mighty Air, Inc. at (904) 292-0636 to schedule heating service in Jacksonville.Most Jacksonville homes heat with a heat pump. The same system that cools your home all summer reverses on cooler days to bring heat inside, which makes it a practical fit for Florida's short winters.
Because heating systems here can sit unused for months, problems often show up on the first cold night. A heat pump that won't switch into heating mode, a thermostat that stopped responding, or auxiliary heat that runs constantly are all common calls once temperatures drop.
Every service below has its own page with what we check, what we repair, and what to expect. Start with the one that matches what's happening at your property.

A system that has sat since last winter can have worn electrical parts, a thermostat issue, or an airflow problem. We'd rather find it before you need the heat.
Many heat pumps in Northeast Florida use electric heat strips as supplemental, or auxiliary, heat. Auxiliary heat turns on when the heat pump needs extra help, like on colder mornings or during a defrost cycle.
When auxiliary heat isn't working, or runs far more than it should, Mighty Air troubleshoots the components behind it.
A heating problem doesn't automatically mean you need a new system. Mighty Air diagnoses the actual cause before recommending a repair or a replacement, and we explain what we found and your options before any work begins.

Mighty Air also provides select gas furnace services for residential and qualifying light commercial properties. Our team can evaluate compatible gas heating equipment, troubleshoot heating performance issues, and discuss available repair or replacement options based on the system and scope of work.
Heating Replacement Options
When an aging system no longer makes sense to repair, Mighty Air evaluates your existing equipment, system sizing, airflow, ductwork, electrical requirements, and overall comfort needs before recommending a replacement. For most Northeast Florida homes, that means a properly sized heat pump that handles both heating and cooling.
Heating Installation & ReplacementMighty Air provides heating service for homes and light commercial properties throughout Jacksonville, Orange Park, St. Johns, St. Augustine, and nearby communities. Heating performance can also be affected by airflow, ductwork, and thermostat issues, so we look at the whole system, not just the heating equipment.
Schedule a heating inspection before cooler weather arrives. A system that's been idle since last winter can have worn electrical components, thermostat issues, or airflow problems, and it's better to find them before you need the heat. Because heat pumps run in both seasons, regular maintenance matters even more. Mighty Air's Standard and Elite Maintenance Plans include two preventive maintenance visits per year under the plan terms.
Mighty Air is a family-owned Jacksonville company. Our name is on every van and every invoice, which is why we diagnose first and explain your options before any work begins.

Quick answers to the questions Jacksonville homeowners ask us most about heating and heat pumps.
Have a question that isn't here? Call (904) 292-0636 and tell us what's happening.
Schedule Heating ServiceMost use a heat pump, which provides both cooling and heating from one system. Many also have electric heat strips for auxiliary heat on colder days.
Air from a heat pump can feel less hot than air from a furnace, which is normal. Persistent cool air can also point to a thermostat, defrost, reversing valve, or auxiliary heat problem that should be inspected.
Auxiliary heat should only turn on when the heat pump needs extra help. If it runs constantly, the heat pump may not be producing enough heat on its own, and the system should be checked.
Yes. Heating systems can sit idle for months, so an inspection before cold weather helps catch problems before you rely on the heat.
Whether your heat pump isn't keeping up, your auxiliary heat isn't working, or you want your system checked before cold weather, Mighty Air can help.
