AC not cooling but the fan is still running. What has failed?

That points outdoors. The indoor blower is on its own circuit and keeps running when the condenser does not, so the usual causes are a failed run capacitor, a contactor that will not close, a high-pressure trip on a fouled coil, or refrigerant that has leaked away. A frozen evaporator gives the same symptom from the other direction. Meters separate them in minutes.

Should the indoor coil be replaced along with the outdoor unit?

In almost every case, yes. The outdoor and indoor units are engineered and rated as a matched pair, and a new condenser working against an old coil rarely delivers what either was rated for. With the move to R-454B the point is sharper, because the coil and metering device need to suit the new refrigerant. Leaving the old coil in place has a measurable cost.

What does zoning failure look like?

Usually a single floor or wing that will not hold its setpoint while the rest of the house is fine, and a system running far longer than it used to. A damper failed closed starves its zone; one failed open sends conditioned air where it is not called for. The control board logs which zones are calling, and dampers can be driven manually.

How do I know if my duct is losing air into the attic?

Measurably: a static pressure reading that is high for the equipment, a large gap between the temperature leaving the air handler and the temperature at the far registers, and a house that pulls in outside air when the system runs. Visibly, in the attic: separated joints at boots and takeoffs, crushed flexible duct across a truss, torn insulation.

My West Melbourne house is only twenty years old. Is replacement really the question?

Often, yes. Twenty years is at or past the design life of the original equipment, and the parts that fail at that age are the expensive ones: compressor, coil, blower motor. The test is whether the repair is a large fraction of a new system on a unit that will need the next repair soon. Both numbers should arrive in writing.

Air conditioning repair West Melbourne, FL

West Melbourne runs west from the Melbourne city line along New Haven Avenue to I-95 and beyond, about seven miles inland from the Atlantic and four from the lagoon. This is the newest of the mainland cities covered here. The median home dates to 2003, nearly 60 percent of the housing went up after 2000, and under 8 percent predates 1970. Owner occupancy runs at 72.9 percent and household income is the second highest of the ten cities on this site.

What AC repair West Melbourne FL calls turn out to be

First replacements arriving all at once

A house built in 2003 or 2004 received its original equipment then and has been running it ever since. Twenty-plus years is past the point at which a split system is generally expected to be replaced rather than repaired, and West Melbourne has enough houses of that exact vintage that the wave is arriving across whole streets. The conversation here is more often about replacement scope than about a single failed part.

A refrigerant change mid-life

New residential equipment has been manufactured for R-454B since January 2025, and Florida wrote the code provisions for those refrigerants into a supplement to the 2023 Building Code. A 2004 house getting a 2026 system is therefore getting a different refrigerant than its line set and indoor coil were originally matched to, which is why a proper changeout addresses the indoor coil and the line set rather than swapping the outdoor unit alone.

Two-story plans on a single system

A good share of the 2000s stock here is two stories served by one system, and heat behaves exactly as physics predicts: upstairs runs warm while downstairs runs cold. Some of these houses were built with zoning dampers and a control board, and when a damper motor or a zone sensor fails the symptom looks like a capacity problem. Others were never zoned at all, and the fix lives in return placement and airflow balance.

Builder-grade returns and filter grilles

Volume construction tends toward a single central return sized to the minimum. When a homeowner then fits a thicker, denser filter than the grille was designed for, static pressure climbs, the blower works harder, airflow across the evaporator drops, and in the worst case the coil ices. A whistling filter grille is the audible version of a reading a technician can take with a manometer.

How far West Melbourne sits from salt water

Just under seven miles from the Atlantic, West Melbourne falls outside the distance bands that trigger coastal equipment requirements. Standard equipment is appropriate here, and an annual service interval is defensible. What West Melbourne does share with the coast is the humidity load, because the moisture the coil has to remove does not care how far the house is from the surf.

Band by band: coastal AC corrosion.

Heating and heat pump repair West Melbourne, FL

Electricity heats 93.7 percent of West Melbourne homes and gas heats 3.3 percent, so the winter half of the year runs through the same box that cools in summer. On the newer stock that box is a heat pump with a strip heat package sized for the few mornings a year that need it, and a heat pump that has quietly stopped reversing will still keep the house warm on strip heat alone while the bill climbs.

Emergency AC repair West Melbourne, FL: how a call runs

Two loops meet at the coil. The air loop stays indoors; the refrigerant loop crosses the wall to a condenser standing in whatever the air carries, which here is salt.

Because the housing is both new and uniform, West Melbourne service calls concentrate on airflow, controls and the changeover decision rather than on the improvised systems found in older parts of the county. Documentation is usually available, which makes a load calculation on a replacement straightforward rather than archaeological.
