Conquistador Oil Heating & Air Conditioning | Professional HVAC Services in Lancaster, PA

Short cycling in Lancaster homes is often due to a clogged oil filter, a faulty flame sensor, or an improperly sized system for your home. It wastes fuel and strains components. Conquistador's technicians will perform a thorough diagnostic, clean critical parts, replace worn components, and ensure your system is correctly calibrated to run in longer, more efficient cycles, restoring comfort and preventing further damage.

Absolutely. We offer 24/7 emergency service for boiler breakdowns, especially critical during Lancaster's freezing winters. Our team is trained on a wide range of oil boiler brands and models common in the area. We carry many common parts on our trucks to facilitate fast repairs, getting your heat restored as quickly and safely as possible.

We recommend an annual tune-up before each heating season. Our Lancaster-specific maintenance includes cleaning the burner assembly and heat exchanger, checking and adjusting the fuel nozzle, testing safety controls, and inspecting the chimney/flue. This proactive service by Conquistador can prevent most causes of short cycling and sudden failures, ensuring efficiency, safety, and peace of mind all winter long.
