Supreme Air Experience




I've been a customer for years, and this was the first time I had to call back to get them to call me for an appointment. I apparent;y fell through the cracks! However, once the fellow came buy, I got the good and friendly service I have come to expect from their employees. I just hope next time, they get back to me the first time! Convenience loses one star for that! 🙂

Below-Average work




The maintenance technician for the heating system didn’t seem too knowledgeable. When he checked the attached central humidifier, he told me it was not working and needed $600+ in repairs; the unit only cost $500 installed a few years ago. I think he broke it.

Furnace diagnostice




The technician took too long to do his job. I was charged for two hours of service when in fact the job can be done in about an hour. I had Supreme Air did my initial installation of my Trane system in October 2009 and they did not register the product. Therefore, I was not able to get the 10 years part warranty.

Repair leak in hot water generator piping. I performed maintenance on both units. I replaced the air filter on the attic heat pump. I checked the electrical wiring and electrical systems, all are within specification. I did set flow rate to 3 psi pressure drop and calculated heat of extraction. Unit operating above printed data. The attic heat pump is slow to heat but it does operate with 22 degrees temperature rise and pressures are normal. Both units are operating normal. The geo unit had a water leak in one of the fittings on th hot water generator “in” piping. I cut the elbow out and replaced with a shark bite elbow fitting. I checked pips for leaks and left the hot generator turned on.

Replace run capacitor and install Intellistart module. I installed large geo system Intellistart Module and replaced the failed run capacitor. I operated the unit on second stage heat mode. I set flow rate to 6 psi pressure drop and confirmed above average heat of extraction. Temperature rise at 28 degrees. I used jumper wires to bring on the auxiliary heat in correct sequence. I set the zone panel to control auxiliary heat and set the timer for 30 minutes. I pressurized the ground loop to 65 psi. Unit operating normal.

Upon arrival I was told that bathroom thermostat was reading 90 degrees this morning and when heat starts it blows out very cold air. Customer also asked me to look at unit that serves middle area, thermostat right outside of kitchen. Bathroom thermostat currently reading 80 degrees and unit off. Went to roof and found left side dining system, bathroom thermostat, blower door blown off and pulling in outdoor air. Put back into place and tested heat. Found no additional problems with unit. Went back to thermostat and indoor temp dropped to 75. Turned off system and inspected middle dining room unit, kitchen thermostat. Found no problems with unit. Satisfying thermostat. Turned both systems off and indoor temp rose to 80 degrees on thermostat by bathrooms. Can feel a large amount of heat radiating from somewhere but I cannot pinpoint where exactly. Used both of my temperature probes to verify thermostat is reading correct temperatures. When unit is off, indoor temp rose as high as 82. Wh
