"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"I called and they sent someone out the next day. They were prompt and efficient and most of all the swamp cooler was repaired. The price they charged was excellent. I also signed up for a maintenance contract based on how well they took care of this problem. There are not a lot of places left who service swamp coolers so this was a good find. I have already recommended them to my sister for service on the air conditioning system in her home."

"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!"

"It went very well. The technician, Oleg, was on time, fully masked and following safety protocols. He quickly diagnosed problem, replaced the part not working, and cleaned out dryer vents of accumulated lint. The price was fair and dryer now working fine. I use Around the Clock for my AC/Heater annual service and now will be using them for any appliance repairs needed."

"I have used Fred Cold for several years. He is very prompt and reliable and almost always very available. He tries to find the best way to repair the units without having to replace them. And when we have to replace them, his price is very competitive. He is my go to person."

"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."

"Chris, a guy I spoke with at Trinity AC to get these services was SO patient and SO nice. He understood my concerns with my central A/C, recommending me to the best guy for the job. Jimmy the technician was SO nice and SUCH a professional. He gave me a discount just for being a senior citizen! I told him about a previous experience with an A/C repair company that attempted to rip me off, giving me high prices for little work. Jimmy heard this, shamed the anonymous man, and took matters into his own hand, doing amazing work and offering better pricing. I would recommend this company to everyone!"

"The entire team at Season Control is top notch. From Donnie, Libar and Chris, the people out in the field, to the office staff Ernie and Pilar, I am so happy to have found this company. After being years with another service company, I interviewed several companies and was happy I made the right choice. We have 2 Commercial buildings that consists of 18 total package units that require a lot of attention. Since signing up with Season control our systems have been dialed in and just in time for Summer. I cant say enough about Donnie, the supervisor. He is responsive, attentive and always available to answer my questions or jump on a repair, just a good guy in general. Our tech, Libar, has become familiar with our locations and feel comfortable knowing he is looking over the systems. I am able to greet them and they know what needs to be done and do not require any hand holding. Another bonus is they are upgrading their monitoring systems and although not everyone likes technology, I see the benefits it will bring and Season Control is staying ahead of their competition. I highly recommend their company as the team there is irreplaceable and would sign up with them with no hesitation."

FAQs for central a/c service or repair projects in South Pasadena, 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.
