What is your equipment telling you?
Pick the unit, what it is doing and how old it is. The right side shows what we would check first, where the unit sits against its expected service life, and what to do next. Most calls we get start with "it's not cooling" or "it keeps tripping," and most of those end in a repair, not a new unit.
Repair territory. A 12-year-old rooftop unit has plenty left in it.
- Check that the unit is actually being called to run: thermostat or BAS schedule, occupied mode, no lockout on the controller.
- On cooling: a dead condenser fan motor, a failed capacitor or contactor, or a low charge from a leak are the usual suspects. On heat: ignition, flame sensor, gas valve or a tripped high limit.
- We test the part, show you the failed one, and repair it once you give the go-ahead.
- Short-cycling and breaker trips are symptoms, not faults. High head pressure from dirty coils or a failed fan, low charge, or a weak compressor will all do it.
- Note which breaker or safety trips and when: at start-up, after 10 minutes, or in the heat of the afternoon. That narrows it fast.
- Resetting it over and over cooks compressors. Leave it off and call.
- Grinding or squealing usually points at bearings, belts, sheaves or a fan motor on its way out. A knock inside a compressor is more serious.
- If the noise is new and getting louder, shut the unit down before a fan blade or motor takes other parts with it.
- We replace belts, bearings and motors, and set belt tension and alignment so it does not come back.
- Write the alarm code down, or photograph the controller screen, before anyone resets it.
- Many alarms (high pressure, low pressure, flow switch, freeze stat) are the controls protecting the equipment from a real mechanical problem somewhere else.
- We read the controller and the equipment together, and repair control cabinets, boards and wiring along with the mechanical side.
- Sticky air with the unit running often means it is short-cycling, oversized for the space, or the dehumidification sequence is not doing its job.
- Sweating ducts, musty smells and wet ceiling tiles are the signs that it has been going on a while.
- We check the coil, airflow, drain and controls, and service dedicated dehumidifiers and natatorium units.
- Dirty coils, loose belts and clogged drains are what turn a normal July afternoon into a service call.
- A maintenance agreement puts every unit on a schedule: filters, belts, coils, electrical, refrigerant and controls checked and written up.
- You get documentation after every visit and a heads-up on equipment that needs budgeting for.
Office and retail: we schedule noisy work and shutdowns around your tenants and business hours.
Plants and process cooling: we work around your production schedule and treat process chillers as the priority they are.
Healthcare: equipment rooms, MRI chillers and critical spaces get planned shutdowns with your facilities team.
Schools and churches: we plan the bigger work for breaks and weekdays between services.
Server and telecom rooms: we keep the room cool first, even with a temporary fix, then repair the unit properly.
Indoor pools: natatorium units carry the humidity load for the whole building, so we check the dehumidification side on every call.
Service life is the ASHRAE median estimate for the equipment type, a rule of thumb. Your unit's real condition decides; we tell you straight when repair stops making sense. Rooftop unitsChillersBoilers and hydronicsCooling towersComputer room coolingAir handlers and makeup air

Four ways we keep a building running
Commercial HVAC service and repair
Troubleshooting on every make and model, from a 2-ton package unit on a strip center to a 120-ton rooftop unit on a plant. We repair older equipment until repair stops making sense.
Preventive maintenance agreements
Every unit on a schedule, every visit written up, and a list of what to budget for next year.
Equipment replacement and retrofits
When a unit is done, we replace it like for like or retrofit it into what the building needs now.
24/7 emergency HVAC service
Server room heating up on a Saturday night, a chiller down in July, no heat on a Monday morning. Call the office number any hour; after hours, the phone menu has an emergency option.
The weekend a TV station almost went off the air
Late on a weekend evening, a TV station's equipment room was overheating. The air conditioning had stopped, the computers were climbing toward shutdown, and the station had already called several companies. Every one of them said nothing could be done until parts were available.
- On arrivalGeorge found the fault: a failed condenser fan motor. No fan, no heat rejection, head pressure through the roof.
- The stopgapHe drove to a hardware store, bought garden soaker hoses, laid them across the condenser coils and hooked them to a water hydrant. The water drizzling over the coil kept head pressure in a safe range.
- The resultThe unit kept cooling, the equipment stayed online and the station stayed on the air until the new motor went in.
We often times are called to the job for a 2nd opinion after the customer was told they need new equipment, and we are able to find the problem, repair it, and get them back up and running, saving the customer thousands.
The equipment we keep running
All makes, old and new. If the manufacturer stopped making the part, we find another way to keep it running.
Chillers
Air-cooled and water-cooled, for comfort cooling and process water.
2 to 120 tonsRooftop and package units
Compressors, fans, economizers, gas heat and controls.
Low pressureBoilers and hydronic pumps
Hot water loops, circulator pumps and the valves between them.
Condenser waterCooling towers
Fans, gearboxes, fill, basins and the pumps that feed the chiller.
Critical coolingComputer room units
Server rooms, telecom closets and MRI chillers that cannot go warm.
Boards and wiringControls and control cabinets
Controllers, contactors, safeties and the wiring that ties them together.
Humidity and airDehumidification and air quality
Makeup air, exhaust fans, humidifiers and natatorium units.

Built around commercial and industrial buildings
Most HVAC companies are residential shops that take the occasional commercial call. We are the opposite: we work only on commercial and industrial equipment, and George Blevens has spent more than 40 years on it. The plant engineers and maintenance directors we work for want the same thing he does: someone they can call who knows their equipment and keeps it running.
- 40+years for George on commercial equipment
- 150+years combined across the Brite team
- 1–200tons, from package units to chillers

Questions facility managers ask us
No. We work only on commercial and industrial equipment: offices, plants, schools, churches, healthcare, retail and multi-tenant buildings. That focus is why we know chillers, boilers and big rooftop units as well as we do.
We repair it until repair is no longer the economical choice. When that day comes, we tell you plainly and help you plan the replacement, instead of pushing a new unit on the first visit.
All of them, including equipment from manufacturers that have merged or stopped making parts. Finding a part or a workable substitute for old equipment is a big share of what we do.
Yes. We walk the equipment, note what condition it is in, and set up a maintenance schedule that fits your building. Your records from the previous contractor help, but we can start without them.
Yes. Shutdowns, crane lifts and noisy work get scheduled around your shifts, services or business hours, and critical cooling gets a temporary plan before anything is turned off.
Yes. We rank the repairs by risk and cost: what can take other equipment or the building down with it comes first, what can wait gets a date. You get that list in writing, and it doubles as a budget plan for replacements coming up.
Yes. Every call ends with a written record of what we found, what we did and anything we recommend watching. Maintenance customers get it for every visit.
