HVAC Services Lexington MA | Call Arlex Oil Corporation

Our technicians are trained to prioritize your family's safety. During every maintenance visit or repair in your Lexington home, we perform a thorough inspection of your heating system, including checking for proper combustion and potential carbon monoxide leaks. We can also discuss and install carbon monoxide detectors as part of a comprehensive home safety plan.

Our preventive maintenance service is designed to keep your system running efficiently and extend its lifespan. For oil heat systems, this includes cleaning the burner assembly, replacing the oil filter and nozzle, checking safety controls, and tuning the system for optimal performance. For air conditioning, we check refrigerant levels, clean coils, and inspect electrical components. This proactive care helps prevent unexpected breakdowns, especially during extreme New England weather.

As a family-owned company serving the area since 1940, we understand the importance of a proper installation. Our process begins with a detailed assessment of your Lexington home's heating and cooling needs. We then provide clear options and work with you to select a system that fits your budget and efficiency goals. Our trained technicians handle the entire installation with care, ensuring your new system is set up correctly for reliable, long-term comfort, backed by our ongoing maintenance and support.
