Systems we are trained and field-experienced on
Each system below, with what the equipment is, what the work involves, and what we need from you before a truck rolls. If you are opening a vendor file, the packet at the bottom of this page is the part to forward.
Wall-mount packaged equipment
BARD units
Wall-mount and self-contained BARD equipment, installed and serviced.
A BARD unit is a self-contained package that hangs on the outside wall of a structure instead of sitting on a roof curb or a concrete pad. Compressor, coil, blower, and controls all live in one cabinet. That is why the equipment turns up where there is no roof to load and no mechanical room to give away: modular classrooms, equipment buildings, shelters, and job trailers.
Servicing one is a different visit from a residential split system. There is no line set running through a wall to a separate condenser, the electrical and the refrigerant circuit share a cabinet, and access is from outside the building. That changes what the trip needs before anyone leaves the shop: a ladder or a lift, clearance at the wall opening, and the voltage on site.
- Installation and replacement of wall-mount and self-contained BARD equipment
- Service and diagnostics on units already in place
Have this ready when you call
- Model and serial number off the data plate
- How the unit is mounted, and the wall opening size
- Voltage and phase at the site
- Whether the structure stays occupied while we work
- Site access, and whether we need an escort
Purpose-built equipment
Northern Air units
Northern Air equipment, installed and serviced.
Call with the data plate in front of you. The model and serial number tell us what we are walking into, what the unit needs, and whether the answer is a part or a replacement.
If a site runs Northern Air equipment alongside wall-mount packages from another manufacturer, say so when you call. One trip that covers both beats two trips that each cover half.
Have this ready when you call
- Model and serial number off the data plate
- What the unit serves, and whether that space stays occupied
- Voltage and phase at the site
- Site access and any escort requirement
Modular building equipment
Marvair units
Marvair ComPac wall-mount equipment on modular buildings, installed and serviced.
A Marvair ComPac is a wall-mount package in the same family as a BARD: compressor, coil, blower, and controls in one cabinet bolted to the outside of the structure, with the supply and return passing through the wall instead of through a duct chase. Modular classrooms, office modules, shelters, and equipment buildings run them for the same reason they run BARD units, which is that there is no roof to load and no mechanical room to give away.
The service visit is mostly access and electrical before it is ever refrigerant. The panel sits behind a door on the face of the unit at height, so the trip needs a ladder or a lift, clearance at the wall, and the voltage and phase on site. Contactors, capacitors, and the low-voltage side account for most of what actually fails on this equipment.
Filters are the other half. These units are usually on a scheduled interval with the change dated on the filter itself, which is what the photo beside this section shows. Tell us the interval you are on and we will work to it rather than guessing at it.

- Scheduled filter and maintenance intervals on modular buildings
Have this ready when you call
- Model and serial number off the data plate
- How the unit is mounted, and whether it needs a lift to reach
- Voltage and phase at the site
- The filter size and the interval the site runs
- Site access, and whether we need an escort
Mobile and modular
HVAC for mobile and modular trailers
Medical trailers, temporary office trailers, and mobile imaging units including mobile MRI and mobile surgical units.
A trailer with a dead HVAC unit is not an uncomfortable room. It is a unit out of service: a schedule that has to be rebuilt, staff standing around, and patients sent somewhere else.
On an imaging trailer the environment is part of the equipment specification, and the imaging manufacturer numbers govern, not ours. Tell us what is inside and what it requires, and we work to that.
On a temporary office trailer the problem is usually access and power before it is ever refrigerant. Where the trailer sits, what feeds it, and what window we are cleared for decide how the visit goes.
- Medical trailers
- Temporary office trailers
- Mobile imaging units, including mobile MRI and mobile surgical
Have this ready when you call
- What the trailer holds, and whether it is under load right now
- Unit make, model, and serial off the data plate
- Site address, and who escorts us on
- Shore power or generator, with voltage and phase
- The window we are allowed to work in
Mission critical
Cooling for data centers and server rooms
Dedicated cooling for server rooms and data floors, where a room past its alarm threshold is an emergency rather than a comfort call.
Server rooms fail quietly. Nobody feels a closet climbing past 90 degrees until something throttles, reboots, or drops off the network, and by then the call is already urgent.
Tell us what the room holds, where the alarm threshold sits, and whether a second unit is carrying load while we work. A room with redundancy can take a scheduled visit. A room without it gets treated as an emergency, because that is what it is.
- Cooling for data centers
- Cooling for server rooms
Have this ready when you call
- Room size and what is running in it
- Existing unit make, model, and serial
- Whether a second unit can carry the load while we work
- Where the alarm threshold sits, and who receives it
- After-hours access, and who signs the work order
Unmanned sites
Environmental control units for cellular communication towers
ECUs on unmanned tower sites, keeping the radios in the shelter inside the range they are rated for.
A tower site is unmanned equipment in a shelter or a cabinet, and the environmental control unit is what keeps the radios inside the range they are rated for. When it quits, nobody is standing there to notice.
Most of the work on these is scheduling and access. Gate codes, escort requirements, and the window we are cleared for shape the visit as much as the fault does. Send that with the ticket and the first trip has a chance of being the only trip.
- Environmental control units at cellular communication tower sites
Have this ready when you call
- Site ID, and the exact address or coordinates
- Gate code, lock type, and any escort requirement
- ECU make, model, and serial
- Whether the site is alarming right now
- Who to call from the gate
For purchasing and facilities
Set us up as a vendor
Send the packet to whoever opens the vendor file, and call the same number when a unit goes down. No portal, no sales sequence.
One-page capability sheet
Capabilities, the specialty systems, the service area, and a contact block. One page, sized to forward or print.
COI and W-9 available on request
Tell us the certificate holder and where it needs to go. Ask for our NAICS code at the same time and we will send it with the W-9.
One number for every site
Indianapolis and surrounding counties across central Indiana. Multi-site portfolios route through the same dispatch number. Calls answered 24/7.

Questions purchasing and facilities ask
What is your lead time on a service call?
For a system that is down, a tech is typically on site in about 2 hours across Indianapolis and surrounding counties. That is a typical time and not a guarantee, and the outer edge of the area runs longer. Scheduled work and equipment replacements depend on the unit and the lead time on it, so ask for a date when you call.
Who answers at 2 AM, and what happens next?
A dedicated line, techs on rotation, and a manager on call who dispatches a tech. Not a voicemail box and not an overflow queue. Office hours are Monday to Friday, 9:00 AM to 5:00 PM, and the phone stays covered outside them. Give the site, the unit, and the access instructions on that first call and the visit gets dispatched off it.
What certifications and licenses do you hold?
EPA 608 certified. Licensed and bonded for roofing. Combined 30 years of HVAC experience. Over 10 years in roofing.
Can you provide a certificate of insurance, a W-9, and a NAICS code?
All three are available on request. Send the certificate holder name, the address it needs to go to, and any wording your system requires, and ask for the packet in the same email.
We have sites in several counties. Can that run through one contact?
We cover Indianapolis and surrounding counties across central Indiana, and a portfolio spread across it routes through one dispatch number. Send the site list with addresses, access notes, and unit tags, and we will tell you plainly which sites we can cover and which sit outside the area.
Do you work under a facilities management firm or a master agreement?
Tell us who holds the agreement and what the onboarding requires. Send the requirements over and we will tell you which ones we can meet today and which ones need a conversation first.
What do you need before a first visit to a secure site?
Site ID and exact address, gate or door access and who holds it, escort and badge requirements, the equipment make and model, and the window we are cleared to work in. Send that with the request and the first trip is a working trip.
