Very satisfied

We got great service from Youssef. He performed our usual check, found a small issue which could have led to a problem and fixed it while he was here.

Checking new system performance

We had a new HVAC system installed earlier this year but noticed that it had trouble keeping up on the very hot (>100 degrees) days. Called Supreme Air and scheduled a service call. Colin quickly diagnosed and remedied the issue. System seems to be performing well.

Tightened electrical connections. Blowers and coils clean. Flushed out drains. Checked operation of both geos. Measured compressor, blower, and loop pump amp draw. Measured heat rise, loop rejection rate, and flow rate. Let systems satisfy thermostat. Tested aux heat. Units operating normal.

I replaced the air filters with ones provided by the customer. I checked the electrical wiring and electrical systems, including auxiliary heat strips, all are within specification. I checked the flow rate and heat of extraction on the Geo unit and pressurized the ground loop to 65psi. I checked defrost cycle on the Amana heat pump. Both units have normal temperature rise in heat pump modes. Units are operating normal. Customer informed me that the condensate drain line that both units drain into, in the basement was clogged. I confirmed this and cut into the drain pipe where it lies against the floor and luckily I was able to remove the clogg which was under the concrete slab with AC Drain Sucker. I poured a few gallons down the drain to make sure it didn’t back up. I glued drain back together with a coupling where I had cut into it.

I installed new Carrier replacement thermostat for the communicating heat pump. I setup the system and showed the customer a few features. We went to test it’s operation and the heat came on but not the cooling. I finally realized that there was a setting I disabled that made it wait 30 minutes before changing between modes. Unit operating normal.
