Signs Your Commercial AC Needs Service

Don’t ignore warning signs of issues with your commercial air conditioning. Catching problems early allows for less expensive repairs and prevents disruptive failures during peak operating hours.

Contact our technicians if you notice:

Increased energy bills
Unexplained spikes in your monthly electricity costs can mean an AC unit is operating inefficiently and using excess energy.
Insufficient cooling
If some offices or rooms are too warm despite the AC running nonstop, there may be underlying mechanical or refrigerant issues.
Strange noises
Unusual rumbling, grinding, or screeching emanating from your AC generally signals a component malfunction needing repair.
Mold/mildew smells
An indoor area giving off musty odors points to condensate drainage problems allowing moisture buildup.
Equipment overheating
Commercial HVAC units should never reach temperatures too hot to touch, which will accelerate wear and failure.
Poor air circulation
Limited air flow from vents or supply ducts results in uneven cooling and indicates blocked equipment filters or fans.
Schedule an inspection immediately if your commercial cooling system displays any of these common warning signs. Catching problems early allows our technicians to restore AC operations quickly, before they spiral into more costly repairs.

Frequently Asked Questions

Commercial AC FAQs

Commercial AC units should be maintained at least twice annually by an HVAC technician. Spring and fall tune-ups are crucial for smooth functioning during the hot and cold seasons. High-traffic sites may require quarterly maintenance.

A standard commercial AC service from Northern Air checks refrigerant and airflow for efficiency, flushes drain lines, lubricates parts, replaces filters, clean coils, looks for leaks or corrosion, confirms safety switches work properly, tests all electrical connections, and conducts a full function test. For commercial clients, our work is tailored to your specific setup. Contact us to discuss what the perfect tune-up would look like for your system.

Replacing systems over 15-20 years old with new ENERGY STAR models provides significant efficiency improvements. Although investment costs are higher, new units pay for themselves through energy cost savings and improved reliability within 5-7 years, depending on the type of business and cooling system.
Some frequent issues in large commercial AC units include low refrigerant levels, clogged coils/filters, electrical control failure, compressor malfunctions, and condensate drainage line blockages. Proper maintenance helps avoid any unplanned failures.
Beyond regular tune-ups and servicing, strategies like installing programmable thermostats, sealing ductwork leaks, adding insulation, performing energy audits, aligning operating hours with occupancy patterns, and adjusting ambient setpoint temperatures can boost efficiency.
Warning signs include increased energy usage, insufficient cooling, unusual sounds/odors, short-cycling on and off, safety trip alarms, and error codes on controller screens, overheating equipment, or limited ventilation from air supply ducts.
Depending on usage levels and regular maintenance, the average lifespan is around 15-20 years for compressors and refrigeration components, and 8-10 years for coils, motors, fans and controls.
