Central air is three things: a condenser outside, an evaporator coil and blower inside, and ductwork joining them. The ducts are what separate it from a ductless system, and in older houses built around radiators they are often a retrofit: small-diameter high-velocity flex duct snaked through walls, with the air handler in the attic. The attic is the hardest place in the house to service in August, and a condensate drain there has to stay clear because everything beneath it is living space.
Outside, the most common failure is small. A condenser that hums while its fan stands still is usually a failed run capacitor, not a compressor.
Inside, the coil is the expensive question. It fails by leaking, and the answer depends on what the system holds. R-22 production ended in 2020, so recharging an R-22 leak buys time on a system that cannot be sustained. R-410A systems are still serviceable, but new equipment built since 2025 uses R-454B or R-32, and a replacement coil must match the outdoor unit's refrigerant and capacity. Past roughly eight to ten years the usual advice is to replace coil and condenser together.
We perform rigorous testing and quality assurance to ensure the system is functioning correctly before providing maintenance recommendations and following up with our clients to ensure their satisfaction.

Troubleshooting guides from our Boston technicians
A humming compressor and warm rooms usually has an upstream cause. The filter, the returns, the outdoor fan and two thermostat traps, in the order a technician checks them.
Most no-heat calls in the first cold week are a switch, a filter, a blocked drain or a sensor with a film on it. The order to work through, the flash code to write down, and the four symptoms that mean stop.
Two honest quotes for the same repair can differ by hundreds. Diagnostic fees, OEM versus generic parts, warranty that covers parts but not labor, refrigerant by the pound, and four questions that make quotes comparable.
A ductless system reports its own faults if you read them. Blink codes, frost on the suction line, the drain that leaks down the wall, and why repeat refrigerant loss is an installation problem.
Refrigerant is not consumed, so a system that is low has a leak. What a real leak search looks like, what the R-410A phase-down changed, and the point where topping up stops being rational.
