Top Quality Commercial AC Repair Company in Texas

CS Mechanical offers maintenance and repair for HVAC systems in commercial buildings such as restaurants, offices, schools, warehouses, healthcare facilities, and more. Commercial HVAC systems are typically larger and more complex than residential systems, and they require specialized knowledge and equipment to repair. To perform commercial HVAC repairs, CS Mechanical will send a team of trained technicians to assess the system, diagnose the problem, and then repair or replace any damaged components.

HVAC System Design & Installation

The layout of your commercial HVAC system can impact the daily operations of the business. Because of this, designing an AC system is one of the most crucial steps in our process. By assessing the building’s needs, CS Mechanical will recommend the best system that is suited for your business. Working with our skilled technicians will ensure your system is energy efficient and functioning at optimal capacity.

CS Mechanical has worked with a wide range of businesses that required different commercial HVAC systems. Some of the most common installations include the following:

  • Boilers
  • Gas furnaces
  • Furnaces or electric furnaces
  • Central heating systems
  • Chillers

Emergency HVAC Repair Services

Businesses such as restaurants and healthcare facilities cannot afford to have a second of downtime on their HVAC system. Humidity and temperature can cause serious damage to a building if it is left unchecked and without routine maintenance.

With that said, CS Mechanical understands the urgency of minimizing downtime and providing long-lasting repairs. Working with CS Mechanical means we’ll assess and repair your commercial HVAC system as soon as we receive the call. Additionally, we’ll work with you to determine what preventative maintenance is best suited for your needs. That way, you can keep your system running efficiently for longer.

Most importantly, Texas is well-known for its humidity levels and high heat temperatures — especially across Houston, Dallas, Austin, and the rest of East Texas. Because of this combination, Texas-based businesses must invest wisely in their commercial HVAC systems. Otherwise, your business could suffer from severe heat, slowing business operations and deterring customers.

How long do commercial HVAC systems last?

A commercial HVAC system typically lasts 15 to 20 years.

However, the lifespan of your commercial HVAC will vary based on how it’s maintained. For that reason, it’s vital you invest in preventative maintenance. That way, you can save on repairs and reduce downtime.

Furthermore, it’s vital you seek commercial HVAC repairs as soon as you notice an issue with your system. The longer you wait to get your HVAC system inspected, the worse the issue will become. So, don’t wait and give CS Mechanical a call today for same-day service.

How much does a commercial HVAC cost?

The cost of a commercial HVAC will depend on the size of your building, the type of system you choose, the installation, and many other factors.

Above all, you shouldn’t only consider the price tag of your HVAC system but also the long-term cost, such as maintenance and the cost to run the system. All of these factors play a role in the cost of your HVAC system.

Overall, it’s crucial to speak with a commercial HVAC technician to learn more about the cost-effectiveness of your system. They’ll work with you to determine what system is best for your needs while also meeting the price point you want.

What are the most common commercial HVAC problems?

  • Clogged or dirty air filters
  • Air duct inefficiency
  • Noisy system
  • Unresponsive
  • Refrigerant leaks
  • Drain line problems

If you’re experiencing a problem with your commercial HVAC or refrigeration unit, reach out to CS Mechanical for same-day service. Our certified technicians will provide you with a thorough inspection and diagnosis of the problem before providing you with the best solution.

What are the types of commercial HVAC systems?

There are four common types of commercial HVAC systems:

  • Single-split system: Designed for smaller commercial spaces, single-split systems consist of an AC, furnace, evaporator coil, and refrigerant. A thermostat controls this system, and it’s most often used in restaurants, bars, individual offices, stores, and other smaller businesses.
  • Multi-split system: Similar to single-split systems, multi-split systems use multiple units to cool or heat a commercial space. Thus, the system reduces the energy needed to control the temperature, reducing utility costs. These systems require less space for the units but require more ductwork.
  • Variable refrigerant flow (VRF) system: VRF systems are a newer HVAC technology that uses variable motor speeds to control the temperature in different areas of a property. As a result, each part of the property can have a different temperature. VRF systems are designed for larger properties, such as an office building or hotel.
  • Variable air volume (VAV) system: Within VAV systems, there are various types to choose from. However, they all meet the heating and cooling requirements of large commercial properties at the same time.
