Jonathan has been our chief technician for several years & is among the very best, who have serviced our geothermal system He’s friendly, knowledgeable, and thorough in explaining work done as well as any other issues that need attention. We’re totally satisfied & would highly recommend him to carry out any HVAC work you may need. Thanks, Jonathan!
The company fixed an issue with the boiler on my radiant heating. They were very responsive and quick to set up an appointment. The technician (Randy) was professional and knowledgeable. Would recommend.
I'm so pleased that the transition from Nelson Comfort to National Heating and Air Conditioning has been so smooth. National is obviously a gold standard sort of business; from the moment I scheduled the routine furnace check-up to the end of the servicing, everything was great! Thanks a bunch! :-)
Had my yearly furnace service completed. Technician (Jonathan) was personable, professional, thorough, and timely. Appreciated the email/text/phone reminder/notifications.
Brandon was my technician he was great and very communicative at every step of the job. This company works fast and well organized. I'll be scheduling next year for maintenance again!!
