Oil Boiler Maintenance, Repair & Installation
Burner tune-ups, nozzle and filter service, and reliable oil heat for homes not on gas
A premium take on oil boiler maintenance, repair & installation
Oil heat is still common from Winchester and Reading out to Lynnfield and Saugus, and an oil boiler needs a yearly cleaning to burn clean and stay efficient. Garcia Services HVAC handles the full annual service: new nozzle and oil filter, strainer and pump screen cleaning, electrodes set, combustion tested with a smoke and efficiency reading, and the flue passages brushed out. We repair burners, controls, and circulators, and when a boiler is at the end of its life we install new oil-fired equipment or help you plan a switch to a heat pump system.
This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.

Service or Install
The cleaning or repair is completed and the burner retuned. Installations include new piping, controls, and venting.
