Retrofit/Design Build

We specialize in upgrading and replacing outdated parts or equipment in older structures to help prevent downtime in your facility and increase energy efficiency.


Building owners often face challenges when replacing mechanical equipment due to the existing mechanical room footprint or system constraints. Our experienced team offers a free assessment of the complete current HVAC system and equipment before recommending the appropriate replacement parts or accessories. We have professional engineers on staff who can analyze and assess both your current system and any potential improvements.

We can also provide preventative maintenance to help increase the longevity of your current equipment and to help ensure that your older systems run smoothly until the time comes to replace them. We follow recommended OEM maintenance schedules for all preventative maintenance. As our technicians are on-site, they can regularly inspect your equipment to be sure that each piece of HVAC equipment is running effectively and is in good condition. Regular recommended maintenance based on OEM guidelines is the best way to help prevent costly downtime. 


The retrofit services we offer can help increase the efficiency of your facility and potentially prevent or reduce HVAC equipment downtime, allowing you to save money while providing maximum occupant comfort for increased productivity and job satisfaction.
