Commercial AC Problems We Repair

Commercial systems are larger and more complex than residential ones, and a breakdown affects your staff, customers and stock. Our technicians are trained on commercial equipment and repair common problems including:

• Refrigerant leaks
• Failed or failing compressors
• Power and electrical problems, including contactors, capacitors and control boards
• Frozen evaporator coils
• Condenser and blower fan motor failures
• Worn or broken fan belts
• Clogged condensate drains and overflowing pans
• Economizer and damper faults
• Thermostat and control problems

We take the time to diagnose the real cause, explain what’s needed and answer your questions before we make the repair.

Fast, Professional Response

When the AC fails in a restaurant kitchen, a retail floor or an office in July, every hour counts. Our technicians are available for same-day commercial repairs whenever our schedule allows, Monday to Friday 8:00 AM to 5:00 PM and Saturday 8:00 AM to 4:00 PM. They arrive on time in fully equipped service trucks, so most repairs are finished on the first visit. If a part has to be ordered, we tell you when it will arrive and get you running again as quickly as possible.

Before We Arrive: How to Speed Up Your Service Call

A few details when you call help us send the right technician with the right parts:

• What the system is doing: no cooling, no heat, short cycling, water leaking, unusual noise or an error code on the thermostat.
• Which units are affected, and how many units serve the building.
• The equipment brand and model if you can see it, especially for rooftop units.
• Roof and equipment access: roof hatch or ladder, keys, alarm codes, and anyone the technician should check in with on site.
• Your operating hours and any times work should avoid, such as a lunch rush or customer appointments.

Until we arrive, set the thermostat to Off if a unit is iced over, leaking water or making grinding noises. That helps prevent further damage.

Retrofit or Replace?

Every commercial system wears out eventually. When repairs are frequent or energy costs keep rising, you have two options:

• Retrofit: upgrade selected parts, such as motors, compressors, controls or economizers, in the existing system. It costs less upfront, causes less disruption and can noticeably improve efficiency.
• Replace: install new, high-efficiency equipment. It costs more upfront but gives the biggest long-term energy savings and reliability, and it may qualify for energy incentives.

We’ll assess your equipment and give you an honest comparison of cost, energy savings and disruption to your business. Learn more about commercial HVAC retrofits.

Commercial Maintenance Agreements

Planned maintenance is the most reliable way to avoid emergency repairs. A commercial maintenance agreement with M&S helps you get:

• fewer breakdowns and emergency calls,
• longer equipment life,
• lower operating costs and energy use,
• more consistent comfort for employees and customers, and
• small problems found and fixed before they become major repairs.

Maintenance visits include filter changes, cleaning the coils and drains, checking the refrigerant, checking belts and motors, testing the electrical parts and controls, and inspecting the heating section and safety controls. We set the schedule around your equipment and your business hours.

Commercial HVAC in the Northern Nevada Climate

Rooftop units in Sparks and Reno face intense summer sun, high-desert dust, wildfire smoke and freezing winter nights, all at about 4,400 feet. Dirty condenser coils and clogged filters are the main reasons commercial units lose capacity during heat waves. Gas heat sections need correct combustion setup at our altitude. Regular coil cleaning, filter changes and seasonal checks before summer and winter make a measurable difference to reliability and energy costs.

Commercial HVAC FAQs

Do you repair rooftop units?

Yes. We repair and maintain rooftop packaged units, which combine heating and cooling in one cabinet and are the most common system on commercial buildings in our area.

How quickly can you respond to a commercial AC breakdown?

We offer same-day commercial repair service whenever our schedule allows during business hours. Businesses with a maintenance agreement get priority scheduling. Call (775) 843-7930 as early in the day as possible.

Should we retrofit or replace our commercial HVAC system?

It depends on the age and condition of the equipment, your energy costs and how much downtime your business can accept. A retrofit costs less upfront and causes less disruption. Replacement gives the biggest long-term efficiency gain. We’ll assess your system and compare both options.

Yes. We offer commercial maintenance agreements built around your equipment and operating schedule, to reduce breakdowns, extend equipment life and lower operating costs.
