"Michael arrived to fix our main water line after it ruptured. He was able to quickly replace the main riser and also had time to take care of a couple other repairs around the house that needed attention. Great service."

"It was over 90 degrees outside and the A/C was not blowing cold air. I called and explained it was for my 85 year old mother who was in home Hospice with end stage Parkinson's. I was worried she may get a heat stroke. They scheduled a service tech to visit in a timely manner. The service tech called an hour before the scheduled appointment to let me know he was on his way. Mark (service tech) was very professional and friendly. He not only got the A/C compressor to work but checked the Freon pressure and went in the basement to inspect the remainder of the equipment. He explained what might need replacing in the near future. Now I am not worried about my mother getting heat. I highly recommend this company for any heating and cooling repairs."

"Michael Amato came out to service my A/C as it was not cooling. Whole process was phenomenal, from start to middle to end. He took his time to go over the unit and even teach me about my system. After finding the issue he built over 5 estimates and as much as I would love a new system, it wasn’t in the budget and instead of just walking away he offered a reasonable priced membership which discounted my current repair! Honestly an awesome experience all around, highly recommend ServLegacy to anybody looking for ac system repairs or replacements and if possible, ask for Michael!"

FAQs for central a/c service or repair projects in West Covina, CA

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
