"I called just minutes before 10pm and expected to be told I'd have to wait until morning for a plumbing issue. Instead Jake showed up happy, polite and willing to find and solve our issue with in 35 to 40 min. Let me tell you Jake worked on our house for 2 hours solid, determined to fix our problem. Jerry showed up after Jake had been diligently trying everything to offer an extra hand. Both Jerry and Jake then worked an additional hour before finding and fixing our issue. Let me tell you, it was now very close to 2am!!!!!! This customer service, dedication and hard work was appreciated so much! I cannot say enough good things about Jake, Jerry or this company. Very honest, hard working people. Its hard to find this type of buisness nowdays!!!!! If i ever have another issue I will only call and use Liberty Plumbing and Heating. I sincerely Thank you for everything!!!!!"

"At the beginning of the heatwave last week, I received a call from the family renting my condo in East County and they informed me that the AC stopped working. I tried a half dozen HVAC companies and none of them were available to provide service until the end of the week. I received a call from JMS West HVAC and they were available to provide service on that same day! Within two hours, the AC unit was repaired and my rental family was safe for the long hot week. The JMS repair crew was extremely professional and took care of business. Thank you!"

FAQs for central a/c service or repair projects in San Marcos, 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.
