"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"We had an HVAC issue develop on a Sunday. Contacted MSP and they scheduled a technician for Monday. They called us back an hour later and said they had a technician come available and asked if we were interested in getting serviced right away at the same service rate. The technician came by, fixed our system and even gave us some tips on our system. Very professional and informative. Excellent experience."

"Fantastic. Finally A/C working way it should with new units, easy control with smart thermostat. Steve and Jake were professional and did great job."

"HD Mechanical got all our commercials units back in order. They provided excellent customer service and we will be using them from now on for all our commercial and residential HVAC needs!"

"Thank you First Class They did a full service on my unit and everything was handled quickly and efficiently. The team was on time, respectful, and clearly knew what they were doing. Highly recommend them for anyone needing reliable HVAC work! Thanks boys"

"They came out and fixed my HVAC system and did not upsell me on anything. Really professional and would absolutely recommend again."

"Excellent service. HVAC installation was done in one day."

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"He showed up on time and checked out the a/c and the furnace unit as requested. The price was higher than expected, but when we talked to the manager he reduced it. I would recommend this company."
