HVAC Repair Brooklyn NY | Call Lighthouse HVAC

Short cycling is a common issue in older Brooklyn homes, often caused by an oversized system, a clogged air filter, or a faulty thermostat. It wastes energy and strains your equipment. Our technicians are familiar with these local system quirks. We'll diagnose the root cause, whether it's a simple filter replacement or a more complex control board issue, and provide a clear, upfront repair plan to restore efficient, reliable heating and help lower those high energy bills.

Our standard residential duct cleaning service is a thorough, multi-step process. First, we inspect your ductwork with specialized cameras. Then, using powerful truck-mounted vacuum systems and agitation tools, we remove dust, debris, and allergens from the entire system. This includes the main trunk lines, all supply and return registers, and the air handler unit. We also offer optional duct sanitization for an added layer of cleanliness. Our goal is to improve your home's air quality and system efficiency.
