"Found these guys through a mutual friend and hired them to fix my air conditioner but upon arrival it was so far gone in repairing that it needed to be replaced. I understood that with the age of the system it was time to upgrade. They gave me a great/reasonable price to replace my system and did a fantastic job. I have been with good ac now for a month and will use them in the future and refer to people. Hands down one of the best experiences I’ve had!"

We found Frank on craigslist and I did a lot of homework before we decided on him. He promptly came out for an initial estimate.

He could have not have been any more understanding or nicer. He listen to what we needed and then gave me several different options.

No pressure sale B.S. He knows his stuff inside and out.

Gave a deposit and a week later the work was done. Everything looks great.

Only time will tell about the unit but Frank has made a customer for life.

I never write these reviews but felt that the negative review he already had did not warrant his

overall services.

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"After several repairs over a couple of years we decided to replace our 14 year old central AC system with a new heat pump system. We got quotes from 3 companies, and decided to go with B.A.R. Appliances AC LLC based on past experience, extended warranty, and very competitive costs. The entire installation was efficient and professional. I found Henry and his staff a pleasure to deal with. They left me with a nice clean system and I would highly recommend B.A.R. Appliances AC LLC for any HVAC work. It's nice to have quality work done in this day and age!"

FAQs for central a/c service or repair projects in Christiana, PA

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.
