"I needed my laundry room drain unclogged. I posted the job on Saturday night for work to be done on Tuesday morning. Jim called Sunday morning, said he was available that day. Came out relatively quick and the job was done within the hour. I highly recommend Jim. I'm certainly going to give him a call the next time I need work done."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Mr. Coffee is a hero who risks his health daily to help mitigate dangerous radon problems for strangers who call for help. This is a dangerous job with daily high radon exposure and when I asked, he said he is aware of the risks but gets his health scanned multiple times a year. I called Covenant Air back in December after noticing that my Safety Siren Pro radon detector kept reaching alarm. Mr. Coffee came out and assessed that I could probably fix the problem myself by sealing some obvious cracks, especially around some pipes, and recommended the products so that I can do it cheap DIY. He was obviously not pushy to scare people into signing contracts, but actually tried to dissuade me from hiring him right off on installing sub slab depressurization. Although the DYI route he recommended would've been cheaper, I hired him to performs the job. The sealing did bring the radon level down where my detector's alarm didn't go off, but I wanted to lower it as much as possible. He then recommended a passive ventilation route given my reading. The passive ventilation again slashed the radon level in half, but I wanted the radon level down even further, so I ultimately opted to install the fan after weeks of data collection and analysis. He installed the fan so that I could easily turn it off to save energy based on seasonal variations. He is a very personable and methodical person, and prefers to monitor the progress of his work so that his customers don't hastily incur unnecessary cost. You almost never see someone like that in the service industry, and I cannot recommend him highly enough.

"My freezer started spraying water out of the back of the water line the night before I went on vacation. When I tried to fix the water line myself, it stopped making ice and kept spraying water. So I turned off the water and left for a week. When I got back on Saturday evening, I called On-Call Maintenance and we scheduled a service call for Sunday morning. He was quick to figure out what the problem was (a broken valve inside the freezer), had to go to Lowe's to get a part, and was quick to get it put together again. He explained what he did while we waited for the ice thingy to fill up. The price was good and the Sunday appointment was a life saver, since it's hard to take off work to meet a repair person."

"Overall, it was a good experience. AAA put down a vapor barrier and installed a Santa Fe dehumidifier with sump pump. The result is that we can now use the stand-up basement/crawlspace to store things under the house without ruining them. This is the part that you need to know. The installation was not without problems. First, they broke an A/C drain pipe, second, they cut a sprinkler controller wire while running a PVC pipe. Here's my take, accidents happen but how does the business respond to these issues? Well, Donna was very quick to send her team out to correct the problems and they even paid for the damage to the sprinkler system. To me, that's top notch customer service. Any business can make a mistake, but how they handle it is the mark of a good company. Every time I lift the roll door and go into the basement now, I'm amazed at how cool and fresh the air is down there. No more mildew and no more smell."

FAQs for central a/c service or repair projects in Decatur, TN

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.
