Commercial HVAC Rooftop Unit Maintenance

Rooftop units run hard and fail at the worst time, usually the first hot week of the year. Scheduled preventive maintenance catches worn belts, dirty coils and low refrigerant before a tenant is sweating, performed by a verified licensed HVAC contractor.

Preventive maintenance for rooftop and split systems

Each visit covers filters, belts, coils, drain lines, refrigerant pressures, electrical readings and controls, with a written condition report per unit. NorTech connects you with licensed C-20 HVAC contractors whose license is verified before they can take the work.

Quarterly, semi-annual or annual

Retail and restaurants generally need quarterly service, offices are fine with two visits a year, and light-use spaces may only need one. The report from each visit tells you what to fix now and what can wait, so repairs are planned instead of urgent.
