Called three companies for a no-cool emergency in Diamond Bar. These were the only ones who gave a real arrival time and actually kept it.
Angela D., Diamond BarCalled at 10 pm on a Saturday with no heat and someone actually answered. The furnace was running again before midnight. Cannot recommend them enough for anyone in Diamond Bar.
David R., Diamond BarFurnace kept shutting off every few minutes. They found a dirty flame sensor and a clogged filter, cleaned both, and it has run perfectly since. Quick and affordable AC service.
Carlos V., Diamond BarOnce a year, ideally in spring before the first heat wave hits Diamond Bar. Systems that run most of the year benefit from a second visit in late summer.
Service is the preventive tune-up and cleaning; repair fixes a specific failure. Our service visit includes a full inspection, so if a part is failing we can repair it on the same trip.
Usually yes. Dirty coils and low refrigerant can raise energy use by 20 to 30 percent. Cleaning and correcting the charge restores the efficiency your system had when new.
