Citywide Cooling Residential Preventive Maintenance Detail

With residential heating and cooling applications, City Cooling & Heating always starts with a system safety evaluation. This covers carbon monoxide detectors, air quality, air filtration and humidification, condition of machinery, and gas and/or oil delivery and inspection.
