With its own cooling. Servers give off heat around the clock, including nights and weekends when the building's system may be set back or off. A dedicated ductless unit keeps the room cool without over-cooling the offices around it. See [ductless heat pumps](https://lancasterheatingandcooling.ca/heat-pumps/ductless/). ### Why do some offices run hot while others are cold? Offices on outside walls gain and lose heat with the weather and the sun, interior rooms stay warm all year, and meeting rooms heat up when they're full. When one thermostat or one zone serves all of them, someone is always uncomfortable. Balancing the ductwork, adding zones or a ductless unit for a problem area can fix it. ### Our office feels stuffy. What can be done? Stuffiness usually means not enough fresh air, or air that isn't moving. Options include bringing in more outdoor air, better filtration and humidity control. We'll check what the current system supplies before recommending changes. See [air quality](https://lancasterheatingandcooling.ca/air-quality/). ### Can you do the work outside office hours? Yes. We plan installations, shutdowns and noisy work around your hours so staff can keep working.
