Air Conditioning

Corroded Condenser Coils

The outdoor unit is constantly exposed to the salt-heavy, moist air rolling in off the coast. This local environment is highly corrosive to the delicate aluminum fins and copper tubing that make up the condenser coil. We see this exact type of environmental wear and tear constantly during our service calls.

The salt eats away at the metal over time, causing microscopic leaks that allow the vital refrigerant gas to escape into the atmosphere. It also creates a thick layer of oxidation that acts as a blanket, preventing the unit from releasing absorbed heat outside. The fix involves precise leak detection, patching if possible, and sometimes replacing the coil entirely to restore proper function.

Clogged Condensate Drain Lines

Your equipment does not just cool the air; it actively dehumidifies it by pulling gallons of water from the indoor atmosphere every day. This condensation collects in a pan and exits the house through a small PVC pipe called a condensate drain. Over time, algae, dust, and biological sludge can accumulate and form a dense clog inside this narrow pipe.

When the pipe backs up, a safety float switch usually trips, shutting down your entire system to prevent water from pouring through your ceiling. This is one of the most frequent calls we get when humidity spikes and the system works overtime. The fix involves professionally clearing the blockage, flushing the line, and ensuring the safety switches are operating correctly.

Failed Capacitors and Contactors

Think of a capacitor as a large battery that gives the heavy motors the sudden jolt of electricity they need to start and run. A contactor is the heavy-duty mechanical switch that physically snaps shut to send high-voltage power to the outdoor machinery. These electrical components sit inside the hot outdoor cabinet and wear out rapidly from heat, age, and frequent cycling.

When they fail, the fan motor or compressor simply will not start, even though the thermostat is calling for cooling and the indoor fan is blowing. The outside unit will just sit there silently, or you might hear a faint clicking or buzzing sound. This is a straightforward repair where we test the microfarad readings and install high-quality replacement parts.

Refrigerant Leaks and Frozen Evaporators

A system does not consume refrigerant like a car consumes gas; it circulates the same charge in a closed loop indefinitely. If you are low on refrigerant, it means there is a physical hole or crack somewhere in the copper lines or coils. When the pressure drops too low, the indoor coil drops below freezing, turning the condensation into a solid block of ice.

This ice completely blocks the airflow, leaving you with warm air or no air coming from the vents. Running the unit while frozen will inevitably destroy the compressor due to liquid slugging back to the outdoor unit. We have to thaw the system safely, locate the microscopic leak, repair the copper, and recharge the system to factory specifications.

Worn Out Blower Motors

The indoor blower motor is the hardest-working component in your house, responsible for pushing conditioned air through every foot of ductwork. Over the years, dust accumulation and continuous friction wear down the bearings inside the motor housing. Eventually, the motor starts drawing too much amperage, overheats, and shuts itself off on a thermal overload.

When the blower fails, the entire heat exchange process stops, and the coils will freeze over very quickly. You might notice the airflow getting progressively weaker over several weeks before it stops entirely. We test the motor’s amp draw and resistance, replacing it with a new, energy-efficient model if the internal windings are burnt.
