G & W Service Co. prides itself on providing solutions and quality repair to commercial construction companies all over the Houston area. Here’s an excellent example of the quality of our work.
Warwick Construction Inc. Warwick Construction, Inc. is a national general contractor specializing in retail and commercial construction. Warwick is licensed in all 50 states and Puerto Rico. Clients include most of the nation’s large and mid-size retailers and developers. They were founded in Houston, Texas in 1999.
Warwick construction had just finished building a Red Robin Restaurant in Katy Texas, after construction was completed the overall restaurant was not staying cool in the dining room or kitchen area. Temperatures were above 78 degrees and in the kitchen area it was up to 90 degrees. After struggling with the original installing contractor, and 5 other commercial contractors, Warwick made some calls around Houston for better help. The G& W Service Co. name kept coming up and when they called us they were looking for a quick solution, the owners of this store were very frustrated. We were contacted to resolve the ongoing issues with of all the HVAC, exhaust and ventilation in the building.
A site visit was requested to access the overall store issues, when we got there we noted many issues related to all HVAC units, supply fans and exhaust fans for the kitchen equipment being ramped up, slowed down, etc. There was HVAC equipment incorrectly setup with many previous contractors making changes to the equipment – i.e. Freon levels(over charging the units to compensate what they thought would be the fix), changing blower pulley to speed up the air, the same on kitchen exhaust and makeup fans slowing down makeup fans and speeding up exhaust. The 5 previous contractors would show up during heat of the day to address all the above issues with no results, the restaurant and kitchen already very warm and dining room was too warm for the customers
The G & W Service Co. Solution:
Addressing all the issues was a step-by-step process, confirming that all the correct equipment was installed and design properly, HVAC units, exhaust system/ makeup air for the kitchen cooking hoods/ dishwashers and restrooms, all engineering was correct, the next step was to set all HVAC units up properly, properly tap the transformers on the units (5 other contractors and the installer missed this!), Set the correct RPM on the blower assay with electronic tachometer and confirm static pressures, set fresh air on each unit per manufacture design, re-installed original pulleys and belts to achieve original airflow as per blueprints when the store was engineered. Next, we set the Freon levels for each HVAC unit, they had been over charged causing poor performance which diminishes capacity to cool the building properly, The exhaust and makeup air systems for the kitchen equipment had similar issues, too much exhaust leaving the building and not enough makeup air coming in the balance the store for proper cooling.
The Conclusion: The Restaurant has never cooled this well since it was opened, the dining room is now steady at 71 degrees and the kitchen is at 76-78 degrees as designed. Warwick Construction hired a true service company that understands HVAC, G & W Service Co. uses properly trained technicians with the proper tools, instruments, with an office support team that puts it all together. Having the experience and knowledge of the HVAC field with ability to put it all together is our biggest success in Houston Texas since 1958.
