"Perfectly! Bill and his associate arrived when they said they would, diagnosed the problem, left to pick up the required part, and returned with the part and installed it, all without a hitch. I particularly liked the way Bill checked to be sure all the functions of the furnace and air conditioner were working before he finished. This is a top-notch service company!"

"Review of inspection and estimate bid process. This is a solid, honest, and professional company. Thank you to Ivan who came out to the property to assess a mainline leak by our sidewalk. He offered impeccable service and respect with understanding of my needs for plumbing repairs. All City came through with requested bids for both a 2 foot patch repair and a full water mainline replacement for several types of piping and methods. Ivan provided proper legal estimate contracts and scope of work details, responded promptly and courteously to all phone calls, emails and texts. As it turned out the County Public Works Department easily fixed the connector leak when repairing the sidewalk concrete and the mainline was confirmed as stable. The mainline had been replaced prior, unbeknownst to me. No extra repairs were needed. I definitely would have contracted All City to do this repair if it was necessary. Ivan is the best, very kind and polite as was the office staff and Dominic who booked the appointment. I’m glad All City is in the OC area! Thank you, it was a pleasure to interact with your company!"

"I’m so glad I called HD mechanical to have my thermostat fixed. We set a time to meet up and he was there on time and very professional. He was very thorough with his work and explained to me all the work he performed. He even checked and serviced my unit, showing me that my filter needed to be changed. Would definitely recommend to anyone who needs and service/repairs done."

"The Tech went above and beyond to do my inspection and service. I did nor buy the yearly maintenance plan and I did not buy the $190. furnace filter ($20) at Home Depot. I had and still have a problem with the system. It makes a growling noise every 2 minutes or so. Thanks so much, anyways."

"OC EXCEL was great! I worked with Ionel (he goes by John) and he was AWESOME! After the a few years back my AC finally broke from all of the ash and I needed to replace it. So after doing some research I met with John for a free estimate. He was super thorough and didn't rush me at all to try and make a sale. He told me what the issues were and what some of my options were and we decided to that it would make the most sense to actually replace the whole system, heating and AC. I didn't think I had the budget to do it, but he knew of some wholesale places that offer full units at discounts and gave me several options to choose from. Of course I looked up the prices for each of the units online to do an independent price comparison and saw his prices were 30% lower! So I had him come over and do the work. I was so impressed with his work style, he's respectful manor throughout the house and his really thoughtful approach. I could tell he was never looking to up sell me on anything and wanted to make sure he provided me the best options available at reasonable costs. It took him the whole day to work here though he only planned for half that time and he never charged me anything extra for the work. For example, apparently my house's attic access hole was too small to get the furnace out!! However, instead of charging me for that extra work he actually made the hole in the attic bigger and was able to get the old one out and install the new one. I asked him several times if this would increase the cost and was more than ready to pay for it, however he said it wasn't my fault the house was built this way and I shouldn't have to pay for it. Plus the price he quoted was what he was going to stick to! I would highly recommend John to anyone looking to fix or replace their AC or Heater! It's hard to find someone in the service industry that's trust worthy but John is definitely one of them."

"Having already consulted with several HVAC businesses about repairing and updating my central air conditioning.. One that I had worked with previously-- but my satisfaction level wasn't that great and the others I was speaking to seem to be setting their rates rather high. So from several reviews and recommendation, I consulted with the SoCal boys.. And I am thrilled that I did. They were prompt, cordial, yet very professional-- respected my own knowledge. We conversed pleasantly then got down to it I was extremely pleased with their knowledge, openness and most of all their honesty! And their prices were more than fair! They knocked it out of the park! I would recommend them highly to just about anyone I know. They have my thanks and my respect!"

FAQs for central a/c service or repair projects in Costa Mesa, 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.
