RTU Service & Replacement in Baytown, TX

Recognizing the signs that your Rooftop Unit (RTU) needs attention can save you from costly breakdowns and lost uptime. Each symptom below points to a specific engineering problem, and the longer it runs undiagnosed, the more it costs you. Look out for these indicators:

• Decreased heating or cooling efficiency: Drop in output often signals refrigerant loss, a failing compressor, or coil fouling. In Baytown's petrochemical corridor, salt and sulfur accelerate coil corrosion up to 40% faster than inland units. What looks like an efficiency problem is frequently a root-cause materials failure.
• Unusual noises: grinding, squealing, banging. These aren't random. Grinding points to bearing wear, squealing to belt or blower motor stress, banging to loose mechanical components. Each one is a measurable failure mode, not a reason to replace the unit outright.
• Frequent cycling on and off: Short-cycling is a system design problem as often as it is an equipment problem. An oversized unit (one that was never right-sized with a proper load calculation) will short-cycle, fail to pull latent humidity, and burn out compressors prematurely. We measure before we quote.
• Increased energy bills without increased usage: Rising amp draw without a change in load is a diagnostic signal. We measure amp draw and Total External Static Pressure (TESP) to identify exactly where the system is working harder than it should, whether that's a duct restriction, a failing motor, or a refrigerant issue.
• Uneven temperatures across different zones: Hot and cold spots aren't a thermostat problem. They indicate duct leakage, static pressure imbalance, or a unit that was never sized to match your building's actual sensible and latent load. Comfort problems have engineering solutions.
• Water leaks around the unit: Standing water or drain pan overflow signals a blocked condensate drain, a refrigerant issue driving ice formation, or in coastal environments, accelerated corrosion compromising the drain pan itself. Ignored, it becomes a structural and air quality problem.
• Unit is over 10–15 years old and experiencing frequent breakdowns: Age alone isn't the trigger. Repair frequency and repair cost relative to replacement value is. We'll give you an honest asset assessment, not a sales pitch. If repair makes more financial sense, we'll tell you that.

Rooftop unit failures don't follow a schedule, and neither do we. Whether you're dealing with an unplanned shutdown, aging equipment that's costing you in energy and repairs, or a new construction project that demands precision from day one, we engineer the right solution for your facility. Every option below starts with diagnostics, not assumptions.

Emergency RTU Repair Services

When an RTU goes down, downtime cost starts immediately. Our technicians arrive with amp draw meters, static pressure gauges, and refrigerant analyzers, not a parts catalog. We diagnose the root cause before we quote the repair, so you're not paying to replace a compressor when a failed contactor or low airflow was the real killer. Fast response, honest diagnosis, documented findings.

Routine RTU Maintenance & Tune-Ups

Reactive repairs cost more than prevention. Every facility manager knows it, but most maintenance programs stop at filter swaps and coil rinses. Ours don't. Our Preventative Maintenance Programs include Total External Static Pressure (TESP) measurement, amp draw trending, refrigerant charge verification, and coil inspection calibrated to Baytown's coastal environment, where salt and sulfur from the petrochemical corridor accelerate coil degradation up to 40% faster than inland sites. We catch the failure curve before it becomes an emergency work order.

Full RTU System Replacement & Installation

We don't pull the old unit's nameplate and order the same tonnage. Every replacement begins with a Manual J load calculation against your current building envelope, occupancy loads, and internal heat gain. An oversized RTU short-cycles, fails to control latent load, and burns out years early. An undersized one runs continuously and still can't hold setpoint on a Baytown August afternoon. Right-sized, right-installed, backed by our 75°F Guarantee on systems we design and install.

RTU Component Upgrades

Full replacement isn't always the answer. If the cabinet and refrigerant circuit are sound, targeted component upgrades can extend equipment life and cut operating costs significantly. We engineer and install economizers for free cooling hours, demand-controlled ventilation controls, variable-speed drives, advanced building automation integration, and barometric relief or bypass dampers where static pressure imbalances are driving comfort complaints. Upgrade the weak link, not the whole system.

Energy Efficiency Assessments for RTUs

High utility bills are a symptom. The cause is usually measurable: degraded economizer operation, refrigerant charge drift, excessive static pressure from undersized or damaged ductwork, or units running outside their rated efficiency curve. We measure before we recommend. Our assessments document actual operating conditions against design specifications and deliver a prioritized action list with projected energy savings tied to each item. Numbers, not guesswork.

Custom RTU Sizing & Selection for New Construction or Retrofits

Spec'd from a square-footage rule of thumb, most commercial RTU selections leave money on the table, or leave occupants uncomfortable. We work directly with general contractors and building owners at the design phase to perform accurate load calculations, account for building envelope performance, ventilation requirements, and sensible-to-latent load ratios specific to Baytown's humidity profile. The result is equipment that performs on day one and year ten. If you're a GC who's been burned by coordination delays and undersized systems at commissioning, let's talk before the slab is poured.
