National Heating & Cooling has been servicing my home since 2011... They are excellent in the service the company provides.. I had DTE out to my home because I smelled gas & the Technician examed my furnace & stated "Whom Ever Installed your furnace did a Good Job"..??. I told him National Heating & Cooling. Thank You Ernie & Adam & the Intern?? Y all I am a legitimate Customer ??

National is always a pleasure to work with. I have used them for my central air, water heater and boiler replacement. From the owner to their service technicians, their service is second to NONE! Whether you need service/repairs or a new system, make sure you give the folks at National a call. They will take great care of you.

5 Star Service all the way around. The installers showed up on time and completed in a timely manner. Very efficient! The service that National Heating and Cooling has provided is nothing short of amazing. Fast response and service. I would highly recommend National Heating and Cooling!! Stress free and headache free!

I had no idea I could be this impressed with an HVAC company. My steam system had some issues, and then my boiler died. National looked great online, so I contacted them along with a couple other local companies, to compare pricing. These guys were SO responsive, professional, and friendly. One company made a vague quote over the phone & said it would be up to a week to order the boiler. Another company came out & gave a quick rough estimate, then sent me a quote (as promised) which was higher. National was actually the least expensive by over $1,000, and they came out & measured every radiator to make sure they had the right size boiler (something the other companies didn't do). They were able to schedule the work right away, & got it done quickly. When there was a further issue with some radiators, they again were super responsive & came out again & made adjustments, replacing several vents, all at no additional cost. I really got the sense that they take pride in their work.

You can count on their estimate and on their customer care. My heat's working better than I thought it could in this drafty old house! I'm glad I found these guys.

This is the first time I post review because I must do this for National H&C inc. Matt and Earnie are great persons and very professional! They did great jobs with reasonable price. Two years labor warranty comes with their jobs and 10 years parts warranty from the manufacturer. I highly recommend National H&C inc if you have troubles with your AC.
