"Hired young and son because my ac wasn't blowing cold air. Julius was the technician that showed up and was very polite, respectful, and very informative answering all of my questions / concerns that i had. Julius had the issue diagnosed and repaired in a very timely matter, and at a very reasonable price. I highly recommend Young and Sons and will tell my friends and family about them if they have any issues. Thanks for the great service Young And Son!"

"These guys are awesome!!!! I woke up at 8am Sunday morning in JULY and my AC WAS OUT! I called three other companies and they either did not answer or I left a message. When I called Metro AC Dewayne answered and told me he could have someone out today, he also explained their emergency call service fee of $150.00 but I totally understood since it was Sunday morning. He took my information and told me a technician would call me within the hour. Larry, the technician called me about 15 min later and said he could be there by 1000am. Dewayne called me back about 45 min later to make sure Larry had called me and set up a time. Larry showed up at around 950. I showed him where the compressor was and that it had been running but the fan had not been spinning. He looked at everything and came in and explained he felt it was only the capacitor but it might be the motor. His plan was the replace capacitor and if that didn't work we would change out the motor. He replaced the capacitor, checked the pressures and temps coming out of AC, changed out my air filter (which he did not have to do) and was done by 1100!! Larry was nice and used shoe covers and was very professional! Metro air conditioning will be my new go to AC and heating repair and maintenance shop!!"

FAQs for central a/c service or repair projects in Sunnyvale, TX

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.
