Professional National Refrigerants Service
Commercial heating systems are essential for comfortable business environments during cooler months. Our commercial furnace services ensure reliable heat when you need it most. We service all major commercial furnace brands including American Standard, Goodman, ICP, Daikin, Johnson Controls, and Thermal Zone. Our technicians are trained in gas furnaces, electric furnaces, and combination heating/cooling systems. Commercial furnaces require regular maintenance and prompt repairs to ensure safety and efficiency. Gas furnaces especially need professional attention for proper combustion, heat exchanger integrity, and carbon monoxide safety. Common furnace problems include no heat, insufficient heat, frequent cycling, unusual noises, high energy bills, pilot light issues, and ignition failures. We diagnose and repair all furnace components including heat exchangers, blower motors, gas valves, ignition systems, and controls. Our furnace installation service includes proper sizing for your building's heating load, equipment selection, professional installation with gas line connections (if applicable), electrical hookup, ductwork connections, venting, and complete system testing. Preventive furnace maintenance is critical for safety and efficiency. Our service includes burner cleaning and adjustment, heat exchanger inspection, flue inspection, filter replacement, blower motor lubrication, electrical connection inspection, thermostat calibration, and carbon monoxide testing. Regular professional maintenance improves heating efficiency up to 20%, prevents dangerous carbon monoxide situations, reduces breakdowns, extends equipment life, and lowers energy costs.

I highly recommend this AC repair company! They did an excellent job fixing my air conditioner — fast, professional, and very reliable. I also had my commercial freezer repaired by them, and just like before, the service was top-notch. Their team really knows what they're doing, and they always make sure everything is working perfectly before they leave. Definitely the best repair service I've worked with!

We had an issue with our walk-in freezer and these guys were amazing. They showed up quickly, diagnosed the problem right away, and had everything up and running in no time. Professional, knowledgeable, and very easy to work with. Highly recommended for any commercial refrigeration needs!

Called them to service a commercial ice machine. They were able to send out a technician the next day. He was able to diagnose the issue and fixed the machine. He also stayed for a few cycles, to make sure the issue was resolved.

We found this company on Google. Iriana is excellent customer service. Alex is genius. He repaired 2 of our refrigerators that had major issues. He found the issue and he fixed it immediately. Request for Alex for sure.

Have a small commercial fridge that was running constantly so needed a check up. seemed the thermostat was broken. got a new one as well as a cleaning of the condensor. working well now hope the electric bill will go down. After a few months I noticed the fixed fridge didn't seem to be working optimally still and had them send a tech out to check. turns out it's a 13 y o fridge with all original parts. a good sign but also a sign that on the original inspection that tech probably should have checked the coolant levels. long story short, turns out after checking the levels were low and more was added. it now is really working as it should. The best part of this review is that after paying, I thought about it more and called them asking for some sort of reduction on the bill as it all could have been addressed in the first visit. I thought only paying for 1/2 of the service fee visit (not the coolant of course) would be a fair compromise. after thinking it over on their end they actually reimbursed me for the entire service fee. I am impressed at their level of service, customer service and business sense.
