- Just like your car, your home systems need yearly maintenance to perform at their best. That's why WholeHome Members get precision-tuned comfort systems. Each year, WholeHome Members choose one core system like a furnace, heat pump, boiler, air conditioner, ductless system, fireplace or generator for a full multi-point tuneup. We clean and test every component: amps, volts, temperature, combustion, refrigerant levels, using factory specifications for precision. We document results, flag concerns and give clear guidance on next steps. The result: better performance, fewer breakdowns, and longer system life.
