Commercial Services

AC Repair, Maintenance, & Installation

Texas is not known for its temperate summers. When the days start to climb into triple-digit heat, you’re going to want a high-quality commercial air conditioning system to keep you comfortably cool. We offer a full range of commercial air conditioning services. If you need a commercial air conditioning system installed, repaired, or maintained, we’re here for you.

There are a lot of ways that a commercial air conditioning system can run into trouble. No matter what the problem is, though, it’s likely to be progressive. The longer a problem is allowed to continue, the more damage it is likely to cause. Over time, even the smallest problem can grow large enough to cause the entire system to break down. That’s why it’s so important to have any problems you notice repaired as quickly as possible. Give us a call today, and we’ll repair your commercial air conditioner for you.

Prompt repairs aren’t the only way to prolong the life of your air conditioner. Annual preventive maintenance is vital to keeping your commercial air conditioner in good health. It’s so important that most systems require it in order to remain under warranty. Scheduling preventive maintenance at least once a year helps your technician identify and repair issues as early as possible, before they have a chance to cause serious damage

Heaters & Boilers

Commercial heaters and boilers are large and complex systems. Proper installation, maintenance, and inspection are crucial for proper operation and performance of these systems. Personnel who try to work on these systems without proper training and equipment are running the chance of severe personal injury or property damage. Our expert technicians all have years of commercial heater installation experience. We’ll make sure that your commercial heating system is installed right the first time, so you can start making use of it right away.

Just like all systems, commercial heaters and boilers require professional attention in order to keep operating at maximum efficiency. Scheduling preventive maintenance at least once a year is highly recommended, as this will allow us to locate and repair any developing problems before they have a chance to fail and cause any damage.

Indoor Air Quality

Though you may not realize it, the quality of your indoor air has a substantial effect on the health of everyone in the building. Microscopic airborne contaminants can cause allergy attacks and illnesses, while humidity imbalances can make it harder to keep cool and easier to get sick. If you don’t have any commercial indoor air quality systems in place, give us a call. We provide a full range of indoor air quality services including air filters, ionization purifiers, UV and germicidal lights. We also offer commercial duct testing, cleaning, and repair.


If the humidity in your air is too high, it can cause a number of negative effects. Increased moisture can promote mold growth, as well as make it harder for your body to cool itself. Commercial dehumidifiers are designed to remove the excess moisture in your air in a number of ways. If you are having problems with high humidity, call and ask about our commercial dehumidifier services.

Duct Cleaning

It is very important to the health of your HVAC system, your building, your employees and your customers to have clean ductwork, but effectively cleaning a commercial ductwork system requires the skills, training and tools of a certified professional. The commercial HVAC experts at Air Services Unlimited have been helping business owners keep their ductwork system healthy and functional for over 30 years. Our duct cleaning equipment utilizes HEPA Filtration to keep your indoor space free of airborne particles as we clean all associated ductwork. We also carry products to fully sanitize and seal your ductwork system after we have thoroughly cleaned it. Another service that we offer is video inspection. This offers peace of mind that you can see when you compare the before/after video of the air you breathe.

Many companies perform duct sanitizing as a separate service; we include it in our duct cleaning services because we know how important it is to have truly clean ductwork in your commercial property.

In a commercial building, there is usually a need for many thermostats working in concert to keep each section of the building comfortable. Each thermostat must be properly wired into the system, so that it is capable of heating the room it serves without conflicting with the other thermostats. Our expert technicians can make sure that every commercial thermostat in your building works in concert, to provide you with the best climate control available.
