"The repairman arrived toward the end of the assigned appointment window, sitting in his truck for 8 minutes before starting work. He examined the system and told me that the evaporator coils were iced-up, and he recommended that we let the system thaw overnight and have another repairman return the next day to add R-22 refrigerant. When I asked him if there were any other options he offered to run the heat cycle to thaw the evaporator coils and then he could make an assessment. After returning outside, I found the repairman running my water hose to cool the compressor, because it had severely overheated and activated a thermal relay preventing the compressor from running (he explained). I inquired about conducting a leak test, and the repairman said it would have to be scheduled another time for an additional charge. I declined the leak test and went inside my home while the compressor finished cooling. When I returned outside, the repairman had added R-22 without advising me of his intentions. Asking how much he added, he said it took two pounds at $95.00/LB R-22. I left and he continued to check the system operation. Working outside my home near my condenser I saw the repairman on his phone. As I walked up to him he told me that the condenser was not operating at the correct pressure and amperage and that he had only seen a compressor fail in this mode "once several years ago." Accordingly, he needed some advice on how to proceed. After discussing the impractical option of replacing the compressor for approximately $2000, he then offered to price a system replacement (without mentioning any need for evaluation or planning: SEER, cooling/heating requirements, square footage, insulation, ducting inspection, permitting, etc). Here is his official proposal that he squeezed into the end of his "DESCRIPTION OF WORK" section on my invoice: "$5746.68 CARRIER 4TON HEAT KIT AND PAD USE EXISTING STAT, STAND, Copper, drain and electrical." Before he prepared his invoice, I told him that I had an Angie's List coupon for $40. When he presented the invoice, it had 2 1/2 pound of R-22 added (versus the 2 pounds he had previously stated). I signed the invoice after discussing this issue, and the repairman departed approximately one hour and twenty-three minutes after he parked his truck. Issue 1: I never explicitly authorized the repairman to add R-22 to my system. Issue 2: After adding refrigerant, he determined that the compressor was defective. Could this not be detected before wasting refrigerant and my money? Issue 3: In the invoice DESCRIPTION OF WORK he notes: "As I added to 3rd lb [R-22] compressor over amped and STARTED clanking. Excessive oil" I suspect that severely overheating a marginally running compressor in a 12-year old condenser unit would cause further problems (apparently a compressor failure)."

"I highly recommend Florida Air Flow Heating and Air for air conditioning repair, zoned ac system repair, and replacement services. The owner Aldi along with his team of technicians has been servicing my ac system for years and he has replaced my system and my sister's system in the past. He always does an amazing job to get someone out to fix your system as soon as possible and his pricing for repairs and replacements is always fair and honest. I recommend Aldi and Florida Air Flow Heating and Air to all of my family and friends and I will continue to do so for the foreseeable future. Thank you Aldi for saving us from the Florida heat during the summers we really appreciate it!"

"It was absolutely amazing to work with E Z air conditioning. He was on time to the appointment and was very clear about what work needed to be done and how much it would cost. When it came to pricing, he was willing to present all the details to me with such clarity that I didn’t feel like he was hiding anything. His candid way of communicating makes you feel like you’re just chatting with a normal person and not a slimy sales guy. The work took about 2 hours and it was worth every penny. Peace of mind and quality work. Thank you E Z Air!!!"

FAQs for central a/c service or repair projects in Saint Johns, FL

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.
