Refrigeration and HVAC systems are critical to your business, and proper maintenance is key to protecting this investment. If a system goes down or operates improperly, costs can skyrocket through unnecessary energy consumption, food or product damage/loss, customer dissatisfaction, and safety risks. Whether it is scheduled preventative maintenance, break-fix, or emergency maintenance, Cold Tech Refrigeration's expert field technicians our ready to respond to your needs, 24/7.

Our technicians are trained in the latest techniques and technologies to address your system's specific issues, regardless of brand. This includes servicing systems that operate with alternative and natural refrigerants like CO2, glycol, ammonia, propane, and R22 replacements such as R407C (for HVAC), R407A (for refrigeration), or other alternatives as desired by the customer. Additionally, our Intelligent Dispatch system ensures we send the right technician for your specific problem, the first time.

Our extensive service offerings for refrigeration and HVAC include:

  • Customized Service Maintenance Agreements
  • Quoted Work
  • Time & Material repairs and maintenance
  • Preventative Maintenance Programs

To help our customers manage their monthly refrigeration & HVAC service and maintenance costs in a more predictable fashion, Cold Tech Refrigeration offers Maintenance Contracts (MAC). MACs operate under a fixed price for monthly maintenance work for a specific scope of work that is often defined through a collaborative effort between our customer and Cold Tech Refrigeration.

MACs are typically renegotiated annually or bi-annually, and contracts typically cover multiple locations. Work on items not specifically defined/covered in the MAC is negotiated with the customer under our Time & Material service offering.



Refrigeration & HVAC systems are complex systems with a lot of critical components that are under constant stress. As part of normal operations, components occasionally wear out; or filters and drains get plugged up. Whether it's sticking valves, broken fans, or a compressor failure, Cold Tech Refrigeration technicians are capable of fixing your system's problems.

We are more than happy to provide you with a fair and reasonable quote in a timely manner to fix or replace the failed component and get your system operating to peak performance as soon as possible. We know that even something that seems as minor as a rattling fan or a plugged drain can have a major impact on your system's performance, cost and most importantly, your customer's shopping experience. Let our Cold Tech Refrigeration  technicians provide you a quote to help make sure minor problems do not become major issues!



Much of our Service & Maintenance work is performed on a time & material (T&M) basis, meaning customers pay for the time it takes to complete a job and the related material. T&M repair work is typically time sensitive and complex; it is a "managed by event" relationship with a customer that allows them to direct and pay for only the desired services they elect to have performed. In many situations Cold Tech has a sole relationship with our T&M customer partners.

Whenever we perform T&M work for any customer we strive to:

  • Match the technician to the specific customer problem.
  • Fix it right the first time (minimize call backs and follow ups).



Determining the type and frequency of Preventative Maintenance (PM) is key to reducing emergency service, equipment down time, loss of sales, refrigerant usage, energy usage, and extending equipment life. Based on years of experience and customer feedback, we have developed two specific PM programs that address our customers' needs:

Cold Tech Refrigeration Quarterly General Maintenance PM - this PM program covers all the basic needs of both small and large mission-critical systems. In multi-site situations, the scope of work is consistent, site-to-site. The program price and the time required to complete the scope of work depends on the size, location, amount and type of equipment located at the site.

Cold Tech Refrigeration Compressor Room and EMS PM's - this bi-annual PM program focuses on high-dollar equipment such as compressors, EMS set points, energy consumption, lighting schedules, anti-sweat and dehumidification. These PM's are performed by our level 5 (or higher) technicians since they require a much more advanced skill set.

Operating Knowledge Concerning Regulatory, 3rd Party Systems — e.g., required paper work, and system entries for the EPA, AQMD, CARB, Verisae, Viryanet, Corrigo etc. — is built into our processes and automated whenever possible.



Managing humidity levels has long been a challenge for grocery stores and other businesses where customer comfort or product integrity depends on proper internal climate. This is especially true in high-humidity climates. The common practice of adjusting a building's air temperature to try to maintain an acceptable humidity level dramatically increases energy use and costs, and can negatively affect customer comfort. Additionally, too much humidity can cause condensation on the refrigerator coils, further increasing energy usage. In a grocery retail setting, frost and ice can form on case doors and the product itself, leading to product deterioration and an undesirable appearance.

The most reliable and cost-effective way to manage the humidity challenge is to install a dehumidification system through a retrofit or remodel or as part of the initial system installation on new construction projects. This valuable investment has been shown to save grocery stores and other businesses tens of thousands of dollars a year in energy savings and operating costs while also dramatically improving the shopping environment for customers and the work environment for employees.

 Cold Tech Refrigeration & HVAC is an expert service provider for mission-critical Refrigeration & HVAC systems, which includes dehumidification. We are trained on all major dehumidification technologies and with all major dehumidification equipment manufacturers.

Cold Tech Refrigeration is ready to service and maintain your dehumidification system investment with scheduled preventative maintenance programs and service. Any unplanned/emergency system or product issues can also be handled in a timely, professional manner, 365/24-7.



With the soaring cost of R-22 refrigerant and rumors of continued price escalations, detecting and fixing refrigerant leaks and performing frequent leak checks is more critical now than ever before! Our service technicians are fully trained to detect, fix and perform leak checks to help you protect your valuable investment in refrigerant. Also, if you do not have a leak detection system installed, contact Cold Tech Refrigeration for a quote and start protecting your refrigerant investment today!



Part of our process when taking over service responsibility at a store or facility for the first time is to "tag" each of your major equipment components with a bar code and then record the unique equipment information (e.g., model, type, serial #, age, if known, etc.) in our hand-held devices which then stores it in our data bases. Each time a service technician services a "tagged" piece of equipment he scans the bar code and records the maintenance or service performed. This allows us to monitor repair/maintenance costs on specific pieces of equipment; information that can be very useful to our customers for repair-or-buy decision-making purposes, and to show the high-cost culprits in your system!

We are also able to perform an "asset tagging" service with the deliverable being a complete list of all your major refrigeration & HVAC components, with parent-child relationships, and specific equipment detail.



Keeping your refrigerated cases clean is a simple, inexpensive way to help ensure their optimal performance and appearance. This simple maintenance routine is often forgotten or overlooked which can lead to problems or system inefficiencies down the road. Contact  Cold Tech Refrigeration and let us perform our comprehensive Case Cleaning service for you, which includes the following steps:

  • Disassemble coil housing.
  • Blow out drains with CO2 as needed.
  • De-ice with hot water and brush (no chemicals).
  • Replace or repair any damaged fan motors/blades.
  • Perform comprehensive leak checks on cases being cleaned, and conduct overall store walk to identify any other refrigerant leaks.
  • Document and notify customer of any and all leaks identified.
  • Restart case and verify operation.
  • Log any service issues.
  • Document temperatures and provide a recap of all work to a store representative. 


Lighting in grocery stores represents about 13% of the electricity consumption, not including the impact on cooling loads. Lighting retrofits to LED lights can save 30 to 60 percent on lighting energy as well as 10 to 20 percent of cooling energy when compared to traditional, fluorescent lighting.

In addition to energy savings, today's LED lighting plays an important role in creating an inviting shopping experience and increasing sales through better product illumination. Advances in LED lighting technology now offer grocery stores an option to fluorescent lighting that produces better lighting, especially in refrigerated display cases because LED lights perform very well in cold temperatures. In fact, research has shown that customers find LED lighting in freezers to be "brighter, more even, more appealing and more comfortable". Packaging and food colors are brighter and more attractive to shippers. Additionally, LED Tube lights will only need to be replaced once every 10 years reducing maintenance and recycling costs.

Our service technicians can provide the service and maintenance you need for your LED lighting.
