AC Maintenance
Seasonal Cooling Care
AC Maintenance That Actually Extends Your System's Life
Most AC breakdowns are preventable. A properly maintained system runs more efficiently, lasts longer, and is far less likely to leave you without cooling on the hottest day of the year.
Northern Air offers seasonal maintenance visits across Washington County and Franklin County, performed by experienced technicians who know what to look for and what to do about it.
More Than a Basic AC Tune-Up
We go beyond checking the filter and calling it a day. We test electrical connections, check refrigerant charge, inspect the coil, clean what needs to be cleaned, and make sure the whole system is operating the way it should.
- Condenser and evaporator coil inspection and cleaning
- Refrigerant level check
- Electrical component testing
- Thermostat calibration
- Air filter check
- Drain line clearing
- Overall system performance assessment
