Ductless Mini-Split Installation
We discuss systems for bedrooms, additions, bonus rooms, cabins, and homes. Project planning includes heat-load considerations, indoor/outdoor placement, cold-weather performance, line sets, condensate drainage, and electrical requirements. Installations are subject to applicable local permits, registrations, and trade requirements.
Monitor Heater Troubleshooting
We investigate error codes, startup failures, fuel-delivery faults, combustion issues, and repeated shutdowns. Because Monitor heaters are discontinued, repair decisions depend on condition and parts.
Toyotomi Laser Service
Diagnostics, cleaning, maintenance, repairs, and replacement options.
Repair or Replace an Older Heater?
A working Monitor may be worth maintaining. Repeated failures, limited parts, or disproportionate repair costs can make replacement more attractive. We explain options rather than assuming replacement is necessary.
Fuel-System Troubleshooting
We also assess tanks, filters, and fuel lines when relevant to heater operation.
Johnson City Appointments
We coordinate visits across Johnson City and surrounding Washington County communities. Share the project address, equipment model, symptoms, and access needs.
