When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.
"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

"They were professional and efficient with the project. My job involved stripping my crabgrass front yard and applying a fresh top soil sod blanket in its place.

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.
