Northstar Cooling

Northstar Cooling runs out of Plano in the DFW area as a straight HVAC shop owned by Hisham Allan. He got started in the trade because machines always made sense to him and opened the doors in 2015 after earning his license. The crew includes licensed technicians who each carry at least ten years on the job, all insured, bonded, and checked before they step on site. They take heating and cooling calls across Plano and the nearby towns, with Hisham making sure every customer gets honest pricing and clear answers from the first phone call through the final walkthrough.

They handle air conditioning repairs when units fail in the middle of summer, swap out central air blower motors that stop working, and perform biannual checkups that catch small problems before they turn into big ones. Hisham leads many of the jobs himself with his team, showing up on time and walking through the system so homeowners know exactly what got fixed. One customer called after four weeks without AC in the DFW heat and got the unit running again at a price that beat every other quote. Another had the furnace serviced so it delivered steady heat without further trouble, while a third needed the blower motor replaced and found the whole process quick and upfront on cost.

Homeowners keep coming back because the crew shows up when promised, explains the work without extra talk, charges fair prices that stay in line with the job, and leaves systems running right the first time. Reviews point to the same things again and again: jobs finished on schedule, no surprise bills, and technicians who treat the house with respect. That record adds up across dozens of calls for furnace maintenance, AC fixes, and motor replacements. DIRT Score 5.0 from 65 reviews on Finds.

“Northstar was amazing! We had been without A/C for over four weeks because of our incompetent home warranty company, and it was incredibly stressful in the intense DFW heat. I called several HVAC companies for estimates and diagnoses, but the prices were through the roof. Then I called Northstar, and Hisham Alan was fantastic. He took the time to explain everything clearly, answered all of my questions, and provided a very fair and reasonable quote with no pressure. His team arrived first thing this morning, was professional, efficient, and completed the job perfectly. We finally have our A/C back and can enjoy a cool home again. Thank you, Hisham Alan and the entire Northstar team, for your honesty, professionalism, and excellent service. I will definitely be using Northstar again and highly recommend them to anyone looking for a trustworthy HVAC company.”

“We had our biannual air conditioning checkup done this morning, and the experience was exceptional from start to finish. The technicians team, led by Hisham Allen himself, arrived right on time, were courteous and professional, and took the time to explain everything clearly. What stood out most was the thoroughness of the inspection. Every component was carefully checked, cleaned, and tested, and nothing felt rushed. The entire process was documented with photos that were sent to me afterward, which added an extra layer of transparency and confidence. It was reassuring to see that level of attention to detail, especially knowing how critical the system is heading into the hotter months. They also shared helpful tips to keep the units performing at their best, which we truly appreciated. This time, for whatever reason, only two of the three units needed filter replacements, even though I had all three ready. That ended up saving me one unused filter for the fall replacement, which I appreciated. There was no upselling or pressure, just honest feedback on the system’s condition and practical guidance for maintaining efficiency. I should also note that in a prior year, Hisham personally helped me replace all three outdoor units when the original HVAC contractor had failed to register the warranties with the manufacturer and coverage was declined. That level of ownership and follow-through left a lasting impression. We have been using this firm for these checkups for years, and this is the first time I am writing a review, although I should have done it much earlier. That, in itself, speaks to the consistency of their service. Thank you for the exceptional support Hisham, it is greatly appreciated. Overall, a smooth and professional experience that gives real peace of mind. Highly recommend for anyone looking to keep their system running reliably.”

“Phenomenal Service! I’ve used many HVAC companies throughout the years and refuse to use anyone else. Hisham and his team are just fantastic. Knowledgable, timely, respectful and trustworthy. Thank y’all for getting our furnaces running properly and doing some maintenance for us today 🙏”

“Central air blower motor went out. Customer service is awesome, pricing is great, honest business is the standard. This is my go to recommendation for any HVAC needs!”

“Fantastic service and fair pricing. This is a company that really cares about solving people's problems, not just trying to squeeze profit out of them. Allen came out to service my HVAC when the heat wouldn't come on. He was thorough, honest, professional, friendly, and insisted on cleaning up a mess that wasn't even his fault. I told him that I like to do as much as I can myself, so once he figured out what the problem was he walked me through exactly how to fix it and then he helped me troubleshoot later in the evening via text message.”
