If we were to talk about like parts that break more often, there's definitely the evaporator coil is about the same as a compressor, slightly less, but it tends to break way more often than the compressor. That also could be the most expensive one if you consider how many times you have to replace it in the lifpan of the unit. [Music]

We service every brand and install Goodman and Daikin AC systems, Rheem water heaters, and Rheem and Halo water softeners. FREE estimates and a FREE diagnosis on service calls.

What is the most expensive part to replace on an AC unit?

The compressor is the most expensive single part to replace on an AC unit, often costing more than half the price of a new system. In Tampa Bay's high-heat, high-humidity climate, compressors work harder and fail sooner. Other costly replacements include the evaporator coil, condenser coil, and refrigerant line set. Home Therapist offers FREE diagnosis on every visit so you know exactly what failed before committing to a repair.

What is the most common part to fail on an AC unit?

Capacitors are the most common AC part to fail, especially in Florida's extreme summer heat. A capacitor stores the electrical charge that starts the compressor and fan motors. When it weakens, the system struggles to start or shuts off unexpectedly. Capacitors are inexpensive to replace compared to major components, and Home Therapist technicians carry them on every service truck for same-day repair.

What AC brands to stay away from?

Home Therapist installs Rheem, Goodman, and Daikin because their parts are widely available and they hold up well in Tampa Bay's coastal salt-air environment. Brands with limited dealer networks or poor parts availability create long repair delays and higher costs. We recommend avoiding any brand your local licensed contractor cannot readily source parts for, regardless of the upfront price.
