I have been using National for past 15 years, never had a problem. In that time they installed an AC unit and a Furnace. Fair pricing of both, excellent workmanship, and the Spring and Fall maintenance is done quickly, professionally, at a good price. I highly recommend National. David Strotman
Thank you for service above and beyond the call of duty! National was able to repair my sister's heating system, although another company told her it HAD to be replaced right away! She is singing your praises and we're all very grateful. Keep up the good work!
Very customer service-oriented. Professional technicians. Came on time and practiced good COVID-19 hygiene. Great people!
Technician came and said the smart thermostat that was in the house was not communicating with the HVAC unit. He wanted to bring another unit that would later on that day. He "no showed"me for a whole day. The next day he brought a thermostat that was not a smart thermostat plus it did not connect to the humidifier. I spent over $700 for a simple thermostat I could have installed myself. He took the smart thermostat that I had already had with him. I guess it wasn't faulty after all. Just checked about thermostat. It costs $100 for the unit. Almost $400 to screw in 6 or 7 wires? You be the judge.
Very professional and friendly. The technicians did a wonderful job servicing my system and it works perfectly.
