Installation, Repair & Maintenance — Broward & Palm Beach Counties
An air handler is the indoor half of a split cooling system. It works alongside your outdoor condenser to deliver cool, dehumidified air through your ductwork.
Inside the cabinet, you will find a blower motor, evaporator coil, and air filter. When your thermostat calls for cooling, the air handler pulls warm return air from your home, runs it across the cold evaporator coil, and pushes conditioned air back through your supply vents.
Without a properly functioning air handler unit, even a brand-new outdoor condenser cannot keep your home comfortable.
The air handler draws warm return air from your living spaces and passes it over the evaporator coil. The coil is filled with refrigerant that absorbs heat and moisture from the air, which is what lowers your indoor temperature and humidity. The blower motor then pushes the cooled air back through your duct system.
Some air handler models also include heat strips for supplemental electric heat during the brief cold periods South Florida occasionally sees.

Every air handler contains several key components that work together to cool and circulate air throughout your home. Hover each card to learn more.
Drives the fan that circulates air through your ductwork. The blower runs continuously during cooling cycles and is one of the most common components to wear over time. A weak motor means uneven airflow and a system that struggles to keep up.
The heart of your cooling system indoors. Refrigerant flows through the coil and absorbs heat as warm air passes over it. A dirty or frozen coil is one of the most common causes of poor cooling performance and warm air coming from vents.
Captures dust, pollen, and debris before they reach the coil. A clogged filter blocks airflow, forces the blower motor to work harder, and can eventually freeze the coil. Most units use standard 1-inch filters and should be replaced every 1 to 3 months. We also offer AC filter replacement service for your convinience.
Electric resistance heating elements installed inside some air handlers for supplemental warmth. Useful in South Florida when overnight lows occasionally dip and the heat pump alone needs a boost.
Air handlers come in several configurations depending on your cooling system and available space.
South Florida runs cooling systems for the better part of twelve months — more run-time than almost anywhere else in the country, putting real demand on every component.
A properly sized and maintained air handler delivers balanced airflow to every room. An undersized or worn unit creates hot spots, forces your outdoor system to run longer cycles, and drives up your energy bill.
The evaporator coil cools the air and pulls moisture out of it at the same time. A clean, well-functioning coil keeps indoor humidity at a comfortable level — critical in South Florida's climate where sticky indoor air is as much a comfort issue as temperature.
Upgrading to a higher-efficiency filter or adding UV lights inside the air handler can significantly reduce airborne particles, mold spores, and bacteria circulating through your home.
Air handler units typically last 15 to 20 years with proper care. Units that go without regular maintenance tend to fail early from dirty coils, clogged drain lines, and worn blower motors — all of which are preventable with routine service.
Air handler replacements cost varies based on unit size, brand, and installation complexity. Unit brand and efficiency rating, coil configuration, whether heat strips are included, ductwork modifications, and installation access all affect final pricing. Attic and closet installs vary in labor as well.
Our technicians install and service all major air handler brands. We recommend equipment based on your system and budget, not a single product line.
If some rooms stay warm while others cool fine, the blower motor may be losing power or the evaporator coil may be restricted or partially frozen.
Ice forming on the evaporator coil means airflow is severely blocked or refrigerant is low. Running the system with a frozen coil can cause compressor damage. Turn the system off and schedule repair promptly.
Water pooling around the unit is almost always a clogged condensate drain line. Left unaddressed, it can cause water damage and create conditions for mold growth inside the air handler cabinet.
Rattling, squealing, or grinding sounds usually point to a failing blower motor or loose internal components. These issues rarely resolve on their own.
A struggling air handler makes the entire cooling system work harder. If your bills are climbing without a change in usage, the indoor unit may be the cause.
If you're seeing any of these signs, don't wait. Schedule AC repair to have your air handler inspected.
Annual professional maintenance keeps your air handler running efficiently and extends its lifespan. For comprehensive seasonal service, see our HVAC maintenance plans.
Dirt and debris on the coil reduce heat transfer and strain the system. A clean coil is the foundation of efficient cooling and proper dehumidification.
We test the blower motor for proper amperage draw and inspect the start and run capacitors for signs of wear before they fail mid-summer.
South Florida's humidity creates the perfect conditions for algae growth in drain lines. Clearing the line prevents water backup, overflow, and mold inside the cabinet.
Loose or corroded connections are a common cause of intermittent faults. We tighten and inspect all terminals inside the air handler cabinet.
An out-of-calibration thermostat causes short-cycling or long run times. We verify it's reading and responding accurately to your settings.
Between visits, replace filters every 1 to 3 months. A clean filter is the single most effective thing you can do to protect your evaporator coil and maintain strong airflow. We also offer AC filter replacement service.
Most air handler units last 15 to 20 years with regular maintenance. Systems that go without routine service often fail earlier due to dirty evaporator coils, clogged condensate drains, or worn blower motors.
Yes. Every air handler has at least one filter slot to protect the evaporator coil from dust and debris. Most residential units use standard 1-inch filters, though some models accommodate thicker media filters for improved air quality.
The condenser is the outdoor unit that releases heat to the outside air. The air handler is the indoor unit that cools and circulates air through your home. Both work together as part of a split system and neither functions properly without the other.
A typical residential air handler replacement runs between $1,800 and $5,000 installed, depending on unit size, brand, and installation requirements.
Yes. UV lights can be installed inside most air handler units to reduce mold, bacteria, and airborne contaminants at the coil. Learn more about UV light installation or ask about it during your next service visit.
Replace filters every 1 to 3 months depending on usage, pets, and air quality. A clogged filter restricts airflow, strains the blower motor, and can cause the evaporator coil to freeze. We offer filter replacement service if you'd like us to handle it.
Yes. Most modern air handlers are compatible with heat pumps and handle both cooling and heating through the same ductwork. Some include heat strips for supplemental electric heat when temperatures drop.
Yes. We install and service commercial air handler units for offices, retail spaces, and light commercial properties throughout South Florida.
