Maintenance Agreements
Commercial HVAC Preventive Maintenance in Dallas
Most commercial breakdowns trace back to something a scheduled visit would have caught: a clogged drain pan, a slipping belt, a coil packed with debris. We run quarterly and monthly agreements built around the equipment on your roof, not a generic checklist, so the visit cadence matches how hard the system actually runs.
- Same-day and next-day service calls
- Chiller plants up to 500 tons
- All major brands
What's covered
Filter changes on a fixed schedule
Replacing filters at intervals matched to the building's occupancy and air quality rather than waiting for a complaint.
Belt and pulley inspection
Checking belt tension and alignment on blower and condenser fan assemblies to prevent slippage and premature wear.
Coil cleaning
Clearing debris and biological buildup from evaporator and condenser coils so heat transfer stays efficient.
Drain pan and condensate line service
Flushing condensate lines and checking pan float switches to prevent overflow and water damage inside the building.
Electrical connection checks
Tightening and inspecting terminals, contactors, and disconnects that loosen from vibration and thermal cycling over time.
Refrigerant charge verification
Checking operating pressures against factory specification to catch a slow leak before it causes a summer failure.
Common symptoms
Facilities usually call about one or more of the following before a tech is ever dispatched.
- Filters visibly caked with dust well before the scheduled change date
- Condensate pan showing standing water or a sour smell
- Belts squealing on startup
- Coils coated in a layer of grime that restricts airflow
- Energy usage drifting upward without a change in occupancy
- Equipment running longer cycles than it did the prior season
How the visit works
- 1 Schedule setup
We build a visit calendar around your equipment count and run hours, whether that means quarterly or monthly service.
- 2 Site visit
The tech works through filters, belts, coils, drain pans, and electrical connections on every unit covered under the agreement.
- 3 Findings discussed on site
Any part nearing failure is flagged to the facility contact directly during the visit so a decision can be made before it breaks.
- 4 Next visit confirmed
Before leaving, the following visit is confirmed on the calendar so maintenance stays on schedule without anyone having to call in.
Equipment we service
Our techs carry diagnostic tools for equipment across manufacturers rather than specializing in one brand. Equipment we service includes:
Related services
Commercial HVAC repair
Facility managers call us when a unit stops cooling, stops heating, or trips a breaker and nobody on staff can tell why.
Rooftop EquipmentRooftop units
Package rooftop units carry most of the conditioning load for retail strips, office parks, and warehouses across DFW, and they take weather that indoor equipment never sees.
Chiller SystemsChiller repair
Chiller plants fail differently than package rooftop units, and a low charge fault on a water-cooled system rarely looks like the same fault on an air-cooled one.
Available across Dallas and Fort Worth
This service runs on the same routes as the rest of our work, across the following areas.
Common questions
How often should a commercial system be serviced?
Most rooftop and split systems do well on a quarterly cadence, while high-use kitchens or 24-hour facilities often move to monthly visits.
What does a maintenance visit actually cover?
Filters, belts, coils, drain pans, electrical connections, and refrigerant charge on every piece of equipment listed in the agreement.
Will a maintenance agreement prevent every breakdown?
No system eliminates every failure, but a regular visit schedule catches the wear items that cause most avoidable summer and winter breakdowns.
Can a maintenance agreement cover multiple buildings?
Yes, agreements are built per property or across a portfolio, with the visit schedule set to match each site's equipment and run hours.
Tell us about the equipment and the symptom, and we will get a technician scheduled.
