Home/Temporary Heating & Cooling Rentals

Temporary Heating & Cooling Rentals

Portable, supplemental and emergency heating and cooling equipment for construction, commercial and industrial projects - delivered, sized and supported by our own HVAC technicians.

Temporary Heating & Cooling Rentals - Alliance Heating & Cooling

Keep the project moving

When permanent equipment cannot keep up

Meeting temporary, portable, supplemental and emergency heating and cooling needs has never been easier. Whether you are curing concrete, protecting pipes from freezing, cooling a server room during a changeover, or keeping tenants comfortable while equipment is replaced, we deliver the equipment that keeps operations running. Because the same team that services your permanent systems rents the temporary ones, sizing is done by people who actually work on HVAC equipment every day.

Planned maintenance and shutdowns without downtime
Fast response when a chiller, boiler or rooftop unit fails
Supplemental capacity during hot or cold extremes
Temporary comfort during renovations and build-outs
