To fully understand what TEM is, it is helpful to understand what TEM is not:

We are not a traditional mechanical contractor, although we do hold a contractor’s license.  We do not install new HVAC systems or components.  We are not in the business of retrofitting existing HVAC systems.  Rather than being competitors, we are partners to mechanical contractors, assisting where temporary HVAC applications exist.

We are not a new or used air conditioning equipment provider.  We do not sell HVAC systems or components – either new or used.  TEM is perfectly positioned to assist OEM HVAC providers as they endeavor to sell their products.

We are not an HVAC service company.  While our technicians maintain and service all of the equipment in our rental inventory, we do not provide labor service for any other equipment.  We do not compete with HVAC service companies.  We do compliment and assist these service companies in providing a more complete offer to end users.

TEM is not a general equipment rental company.  We don’t rent backhoes, air compressors, forklifts, tools, etc. Except in those rare cases where a generator might be required to support our furnished equipment, TEM does not rent generators.

We are not a general equipment rental company that also rents HVAC equipment.

We are not a generator rental company that also provides rentals of HVAC equipment.

We are not a mechanical contractor that sometimes rents old, worn out, used equipment that they removed from a construction project.

TEM is an Air Conditioning Rental Equipment Company.  Since 1985, our heritage, our experience, our expertise, our soul has been firmly grounded in the HVAC and Refrigeration Industries. For 20 years, we have been the problem solvers for those who need assistance with their temporary cooling requirements.  It is all we do.  That is why TEM is truly unique in our field.  That is why we enjoy an outstanding reputation within our service area and why we are blessed with ongoing, repeat business from an excellent client base.
