Servicing 2 Dual Fuel Lennox systems that are on our Planned Maintenance Agreement for an air conditioning tune up. Today I inspected our filter kits and UV bulbs, they’re good until fall this year. Cleaned the indoor coils and drain lines. Checked refrigerant levels and valves. Tested electrical components on both systems and both thermostats. No issues found on either system today, both systems are clean and ready for summer!
