Richardson, TX Commercial AC Repair

At TemperaturePro, our commercial AC repair service in Richardson, TX, covers just about every type of cooling system out there—rooftop units on retail buildings, split systems in office suites, ductless mini splits in server rooms, and multi-zone setups across large facilities. Whether you’re dealing with uneven temperatures throughout a restaurant, a system that won’t turn on in a busy clinic, or equipment that’s icing over in the middle of a shift, we’re ready to fix it.

Here are some of the most common commercial air conditioning issues we resolve:

Inconsistent Cooling Or Poor Airflow

If certain areas of your building aren’t reaching set temperatures or you’re noticing a significant drop in airflow, the issue may involve dirty coils, a worn blower motor, duct obstructions, or refrigerant imbalance. These conditions not only reduce occupant comfort but can overwork the system and lead to larger failures. Resolving this typically requires a full airflow and refrigerant check, followed by cleaning, part replacement, or rebalancing as needed.

AC System Fails To Start Or Cycles Off Unexpectedly

When a unit won’t turn on, starts intermittently, or shuts off without warning, it’s often tied to electrical or control failures. Common causes include failed capacitors, faulty contactors, damaged wiring, or issues within the thermostat or building management system. An accurate diagnosis requires inspection of electrical components and control boards. Repairs may involve replacing failed parts or reprogramming system controls.

Ice Formation Or Unit Blowing Warm Air

If evaporator coils are freezing or the system is blowing warm air under cooling demand, airflow may be restricted or refrigerant levels may be low. Prolonged operation under these conditions risks compressor damage. Technicians will need to safely defrost the unit, identify the underlying issue—such as a failed blower, clogged filter, or leak—and restore proper refrigerant charge or airflow.

Unusual Noises Or Odors During Operation

Mechanical sounds like grinding, squealing, or metal-on-metal contact usually indicate motor or fan assembly wear. Electrical buzzing may signal arcing or control board issues. Odors—burning, musty, or chemical—often point to overheating components, microbial growth, or refrigerant leaks. Addressing these issues typically involves part replacement and system cleaning to prevent further degradation.

Water Leaks, Overflow, Or Moisture Damage

Pooled water near units or signs of water damage in ceilings or mechanical rooms suggest a clogged condensate drain or failed drain pan. While usually a straightforward repair, if not addressed promptly, these issues can result in extensive water damage and indoor air quality problems. Repairs may include clearing lines, replacing pans, and inspecting for mold or secondary structural damage.

With every commercial AC repair, we take time to inspect the entire system, not just the part that’s showing symptoms. That means checking refrigerant levels, airflow, electrical components, and controls to make sure nothing else is at risk of failure. Once we identify the root cause, we’ll explain exactly what’s wrong, what it will take to fix it, and how soon you can expect the system to be fully operational again.

If we see signs that your equipment is aging or under constant strain—like motor failure, compressor damage, or inefficiency—we’ll walk you through the next steps. That includes potential replacement options, cost considerations, and whether it makes more sense to repair or plan for an upgrade.
