Keeping your home comfortable in Florida’s heat and humidity takes a reliable HVAC system and a team you can trust. At J. Molnar Heating & Cooling Inc., we provide honest, dependable Residential HVAC services for homeowners across Lakeland and Central Florida. As a family-owned company since 2008, we pride ourselves on upfront pricing, same-day service, and friendly technicians who treat you like a neighbor. Whether your AC suddenly stopped cooling, your airflow feels weak, or it’s time to replace an older system, we’re here to help with clear communication and quality work you can count on.
Our long cooling season puts a lot of strain on air conditioners and heat pumps. When your system is aging or not maintained properly, it leads to:
With Lakeland’s heat, summer storms, and naturally humid climate, having a properly sized and well-maintained HVAC system isn’t just about comfort. It protects your home and helps your family breathe easier.
If you’re noticing any of these red flags, your system may need repair or maintenance:
Catching issues early can help avoid larger, more expensive repairs down the road.
We offer a complete range of HVAC services to keep your home cool, comfortable, and energy-efficient year-round.
Fast, honest AC repairs for homes across Lakeland and Central Florida. We diagnose issues like refrigerant leaks, electrical failures, clogged drain lines, airflow problems, sensor issues, and more. Our trucks are stocked to complete most AC repairs on the same visit.
Heat pumps are popular in Florida homes, but when they struggle to switch modes, freeze up, or cycle constantly, we can help. We repair reversing valves, defrost boards, electrical components, and performance issues.
If your blower isn’t running, the air handler is leaking, or your home has weak airflow, we’ll inspect the motor, coils, drain pan, electrical components, and duct connections.
Leaky, crushed, or poorly installed ductwork can waste air and increase energy bills. We seal, repair, or replace damaged sections to improve airflow and comfort.
We troubleshoot wiring issues, calibration problems, and malfunctioning thermostats and can upgrade you to a modern smart thermostat if desired.
If your home feels humid, dusty, or has persistent odors, our technicians identify the cause and guide you toward the best solution.
