It depends on the space. Gas-fired unit heaters are a common choice for open areas with high ceilings, because they heat the working area directly and can be placed where they're needed. Spaces with offices or that need cooling may suit rooftop units. We'll look at the size, ceiling height, doors and how the space is used before recommending equipment. ### How do we stop losing heat every time the overhead door opens? A large overhead door can empty a building of warm air in minutes. Placing unit heaters to cover the door area, keeping doors open only as long as needed, and making sure exhaust fans aren't pulling cold air in through the doors all help. If exhaust is the problem, make-up air may be the fix. See [make-up air](https://lancasterheatingandcooling.ca/commercial/make-up-air/). ### Do unit heaters need maintenance? Yes. Like any gas-fired heater, a unit heater should be checked before the heating season: burner, ignition, venting, safety controls and the fan. Dust in shops and warehouses builds up on heaters faster than in offices. See [commercial preventive maintenance](https://lancasterheatingandcooling.ca/commercial/maintenance/). ### Can you run gas lines to new equipment? Yes. Our licensed gas technicians install new gas lines and extensions and connect heaters and other equipment.
