"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!!!!!"

"I never give reviews but Same Day Heating and Air Conditioning absolutely deserves one, From Start to Finish they were professional, respectful and courteous. The Customer service Representative was accommodating with my busy schedule and was able to send a Tech out later than usual to meet me right after work which I was so grateful for since My kitten and I have been freezing!! I ended up running a little late but my technician Sean was understanding and was such a nice guy. Sean was professional,informative and thoroughly explained all my options to me without being pushy, I've had such bad experiences with Service companies in the past trying to pressure me into buying something or replacing something right away but he didn't do any of that. Hands down best Customer Service I've ever received. Same Day will always be my go to for any of my HVAC Needs. Thank You Same Day. My kitten and I Thank you!! We will never go anywhere else!! :)"

"I was an electrical contractor in northern california for 35 years. I can say that Cano Heating & Air conditioning is a class act. Junior met me as scheduled to repair my central air conditioning that was not working. He immediately diagnosed the problem and had the part on his truck to make the repair. Very competent company, I give my highest recommendation to Cano H&A."

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

FAQs for central a/c service or repair projects in La Jolla, 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.
