National Air Systems

Called for service on the furnace in our rental property because the tenant reported it wouldn't turn on. Prior to calling, we went to the home ourselves and checked the fuses and power switches and thermostat and couldn't find any issues. We made an appointment, and were told the technician would be there between 12-2pm. (Gotta love appointment windows!) Anyway, as the house is tenanted, I couldn't just wait in the house, so I sat in my car outside the home waiting for the tech to show up. At 1:00pm I was getting antsy so I called to see if there was an ETA. I was told the service girl was on lunch and no one else could help me. So I called back 2 more times before 2pm, with no sign of the service tech. Finally at 2pm the girl from the office called to tell me that the tech was running late would be there in 10 minutes. At 2:30pm the tech finally showed up. I sat in MY CAR for 2.5 hours waiting for this guy. We finally went in, and he flicked the power switch and the furnace on, just like that. I told him we checked that before, and it didn't work. He said the wiring in the house is old (which is true) so I should check that out but that there was nothing wrong with the furnace. Not sure how he knew that, since he didn't actually do anything to the furnace. This guy was in the house for literally 3 minutes, after showing up late with no call or warning and still charged me the full $100 service call fee. Definitely would NOT recommend this company.

This is my second A/C & humidifier install. The experience with this company is far better than my last experience. Top notch, high quality Carrier products at great prices compared to other companies I called. They also happen to be the installer for our builder, so we were able to maintain our warranty on our furnance. Highly recommended. Even helped me install my new Honeywell thermostat.

Flash forward 7 years... the air conditioning unit they installed has caused us nothing but problems. It leaks refrigerant every 3 years, and struggles to keep the house cool on hot days. We signed up with a protection plan with another company after national air sub contracted our service call to another company who could not find the leak, and charged us $300 to install a new coil when ours was working just fine.... the coil they installed is now too small and causing new problems.
