Seattle commercial HVAC project expertise by K & D Mechanical, Inc. covers a wide range of services using equipment from many manufacturers. From new installs to redesigning ductwork, our team is experienced in all areas of HVAC.
Our Install crew consists of James, Pete, Mike, Brandon, and Justin. Maintenance and routine service is done by Frank and Joseph. Together we work as a team to get Seattle area projects completed to meet the client’s deadline.
Rooftop Unit Installations
We’ve been in business over 20 years and have installed all makes and models of commercial and industrial equipment. We’ve worked with whatever brands the specs include. If left up to us, we chose equipment that best meets the requirements.
- Tacoma expansion of One Main Finance-installed a new rooftop unit and ductwork package to accommodate their new floor plan.
- Teardown and rebuild for Taco Bell in Everett-new Carrier rooftop units were installed with roof curbs to fit cut openings in roof.
Commercial equipment replacements
Replacing aging equipment with more energy efficient models not only saves money but also delivers a higher level of comfort. Upgrades usually go smoothly as new models have similar footprints and adapter roof curbs can be used.
- Krispy Kreme-work went fast thanks to Lennox’s like-for-like unit and adapter curbs.
- Calsak Plastics-removed old split systems to install 2 Trane heating and cooling RTUs involved dropping ductwork down to within 2 ft. of existing distribution ductwork to tie into the existing supply while adding return air trunk lines to new roof units.
- Dollar Tree in Snoqualmie-removed old 30-ton Trane unit from the roof (which we recycled) and installed 5 new roof curbs, rooftop units and ductwork package.
Our expertise with ductwork comes in handy especially when we’re replacing one type of equipment with another, such as RTU’s for split systems.
Specialized dehumidification
Custom solutions are required when a company has industry specific needs, such as those below.
- Solstice-installed 8 RTUs totaling 116 tons of cooling with ARID-Dry 5000/6000 capable of removing up to 300+ gallons of moisture from humid grow room every 24 hours.
- Iora Primary Care-installed high efficiency Trane heating and cooling equipment complete with dehumidification and high CO2 monitoring and ventilation capabilities.
Since we work with all makes and models, it’s simply a matter of choosing the right equipment to do the job.
Redesign vents for improved circulation
When the status quo isn’t doing the job, we figure out what’s not working and devise a different (and better) way to improve air circulation.
- Lazarus Naturals in Ballard-reconfigured venting systems to get more site-specific exhaust accomplished.
- Seattle Glass Blowing Studio-new exhaust venting involved removing old stack & inefficient propeller fan before redesigning ductwork to connect it to high efficiency Captive Aire VFD compatible direct-drive utility set fan.
Hood & exhaust fan with ductwork
Our expertise in ductwork came in handy when Sagemax Bioceramics called because their existing ductwork was damaged and leaking. We replaced it with stainless steel ductwork and installed a new exhaust fan and customer-provided hood while we were there.
Seattle restaurant hood & ventilation
When the Twisted Fork Saloon in Tacoma decided to expand into a full-blown restaurant, it required upgrading their kitchen. Part of our work involved including cutting wall openings for a new grease duct and installing a new CaptiveAire control panel.
Some projects are so big that it requires our whole team, like the Twin Peaks Restaurant. We installed 4 Carrier 12.5-ton rooftop units, ductwork, and kitchen hood exhaust fans.
As we neared opening day, Mike worked on controls for patio heaters while Pete anchored down equipment and installed the last registers. Thermostats and sensors were set up as James worked on ‘start and test’ and everything was done in time.
CaptiveAire hoods offer durability
When you’re in the market for a durable hood that’s going to be up to the challenge of a commercial kitchen, you need CaptiveAire. They have many models that can be configured to meet all exhaust requirements.
- MOD Pizza in Gig Harbor-our fourth MOD location included complete ductwork, CaptiveAire pizza oven hood with venting and register installation.
- Farine Bakery & Café-installed HVAC equipment, mix of exposed spiral ductwork and above grid duct, CaptiveAire hoods, grease duct and equipment, louvers, and refrigerant piping.
Commercial maintenance includes calibration
Many years of experience is what it takes to test and calibrate equipment to make sure we’re hitting our targets. After a pulley and sheave change at the Paradise Inn on Mt. Rainier, we were successful with our upgrade and achieved our CFM/RPM targets on the existing fans on the Gaylord kitchen hoods.
RPM targets
- EF-1 is 2103 (target was 2093)
- EF-2 is 2352 (target was 2332)
CFM targets
- EF-1 is 7,100 (up from 5,100)
- EF-2 is 5,850 (up from 4,120)
Most equipment needs adjusting from time to time and that’s why maintenance is so important. When the Pocock Rowing Center had us install new controls for their locker rooms and conference room, we also made critical adjustments to their 350,000 BTU Reznor (serving multiple zones) to maximize efficiency.
Commercial refrigeration systems
K & D Mechanical does work in a wide array of industries. At Trident Naval Base, we installed air conditioning for their pure waste operations center for the submarines. Once done, the refrigeration systems were pressure tested, evacuated to around 300 microns and each unit’s required R-410A refrigerant has been weighed in.
Refrigeration installs can cover a large scope though we handle all jobs with the same level of care. For example, putting in a new compressor and condenser section for Seattle’s Favorite bagel walk-in cooler is just as important as a large installation.
Why have preventative maintenance?
To get your equipment tested and checked early for signs of problems before they become big ones that are more expensive to fix. Our goal is to minimize any down time due to equipment failure and that’s what we did for Seattle’s Favorite.
Their Quarterly Preventative Maintenance program covers their coolers, freezers, RTU equipment, exhaust, and radiant heaters so when an evaporator coil failed, we had them up and running again fast. While we were there, we also rerouted a 1-1/2 inch, four million BTUs, 2psi gas line to new dishwasher line.
Gas & gas piping work
Seattle commercial HVAC project range of service extends to gas equipment, piping, and other gas-related work.
- Parmigan Ridge in Orting-gas piping plan for their classroom included gas piping install to 9 modular classroom heaters.
- Treasures from the Sea-completed a full HVAC design & build that included upgrading the 4th floor kitchen to a gas range & adding a new gas range on the 1st floor.
As you can see, our Seattle commercial HVAC project range covers a wide spectrum of industries and equipment. Contact K & D Mechanical, Inc. for an estimate on your next install, upgrade or maintenance.
