Jj3 Consulting

JJ3 Consulting works out of Dallas, TX and handles HVAC load calculations for residential and small commercial projects. The business draws on more than 50 years of combined experience in heating and air conditioning to deliver Manual J, S, and D services. They start with architectural blueprints for new construction homes and produce heating and cooling models through Wrightsoft software. Field time spent on actual system installations informs the work, so the calculations stay grounded in practical conditions rather than just meeting basic city requirements in the Dallas area. This keeps costs per project low while giving builders and contractors usable data for their own jobs.

The company runs Manual J calculations to figure air conditioning and heating loads on new builds, then follows up with Manual S to list available equipment model numbers that fit the loads. Manual D work covers duct layouts for both flex and metal systems once the loads are set. Homeowners and contractors in Dallas deal with extreme summer heat that drives up cooling demands, and these calculations help avoid oversized or undersized units that waste energy. Reviews note Matt and his crew handling calls with top results, while others mention solid customer service that includes lending a hand when plans need adjustment and making sure the job gets done right the first time around.

Customers keep coming back for the straightforward communication and solid outcomes on load work that prevents callbacks later. They point to fair pricing that does not add unnecessary extras and quick turnaround that fits tight build schedules in the Dallas market. The mix of experience and software keeps models realistic, which shows up in feedback about reliable service without excuses when something needs fixing. DIRT Score 3.92 from 29 reviews on Finds.

“J3 Company is unprofessional and unwilling to take accountability for the damage caused to my vehicle. It is irresponsible for a crew to leave an elevated water valve protruding so far above ground without any barriers or warning to prevent vehicles from driving near or over it. This situation could have easily been avoided. I sincerely hope no one else experiences this negligence.”
