"The first impression of this company was bad. The first salesman they sent just didn’t seem to care much about my wants. Just bragged about how they were a big company. The dispatcher offered to make up for his poor performance by suggesting I speak to the sales director I agreed but didn’t get a call back. About 5 weeks go by and I got a email from horizon I responded to and within a few hours I received a call. On that call we discussed my plans to go with another company and they were welcome to match or beat their price. Then the sales director called me and apologize for the poor service. And offered to send another guy out said it’s not entirely possible to beat that price due to the difference in service but can try. The new guy came out the following Saturday and was much better than the first. He offered more knowledge and definitely was more geared to what I wanted in terms of comfort and energy efficiency. I went with horizon because they offered a 12 year labor warranty and made it clear that my system would need new copper lines to ensure the new equipment isn’t damaged by old oil from the existing system. The price was very competitive and they still honored a rebate after a day it expired. So far the system is running great the installation was smooth and the installers were nice and considerate considerate my complex installation. I knocked a star off because of the first impression."

"I have a maintenance contract. Today Fabian came out. He was very thorough. He spent two hours at my condo performing all kinds of tests. Before he left he went over things I could do to get better performance from my heater. I appreciate the fact that he did not try to pressure me into picking something. He emailed me (while in the truck) options and also explained different ways to pay for it. He noticed the oxygen in my home. My husband had CHF and COPD so I was specifically interested in the ways I can help his breathing better. I believe in todayâ s environment itâ s difficult for companies to get really good employees. This young man , 20, had a great work ethic and a bright future. Very pleased with the service I have received. Thank you Harris."

FAQs for central a/c service or repair projects in Wilmington, DE

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.
