Job Locations and Reviews
Responded to a home on the outskirts of Giddings where the homeowner said a 16-year-old system had been struggling all summer and finally gave up on one of the hottest afternoons of the year. The compressor locked up and there wasn't any sense putting money into a unit that old. Did a proper load calculation before recommending equipment, removed the old indoor coil and outdoor condenser, and installed a new high-efficiency matched system with updated refrigerant lines and a new filter drier. Charged to spec, balanced airflow through the existing ductwork, and ran a full cooling cycle to confirm everything was delivering correctly. Homeowner said it was already quieter and colder than the old system had been in years.
Upon my arrival I evaluated 2 Goodman gas furnace systems. I verified system safety and performance is to manufacture specifications for both systems. Flushed and treated the water removal systems. Cleaned the electrical cabinets and checked terminals. Did not wash the condenser heat transfer media coils due to the condition of them. Water would destroy the fins and reduce the efficiency of the system. Fixed a loose coupling on the water removal system to prevent any more leaks. Found unit #1 to be low on R22 refrigerant and unit #2s outdoor electrical safety circuit system plug to be very hot, but not overamping. Made sure the plug was all the way in and making good contact. Overheating due to aged and worn terminals. Informed the customer of my findings. And recommended having out comfort specialist come out and give estimates on replacement. The customer wants to let the current systems run as long as they can before replacement. Both systems from 2006. Systems cooling to the best
I returned to the job to re-insulate and reseal the duct run for the entryway. I removed the old insulation and installed new insulation. I resealed all tape points with mastic sealant. Informed customer to wait at least 6 to 8 hours to start system to let the mastic sealant harden. System cooling properly at this time.
Upon my arrival, the customer is concerned that the register above the front entranceway was dripping water. Upon my diagnosis, I found the register to be exposed to the attic air, causing condensation. Will need to return with duct wrap insulation to re-insulate the duct run. The office will be in contact about a date and time for a return.
Summertime AC Maintenance: Completed a pre-summer seasonal tune-up on a residential split system before peak Texas heat. Removed debris and cottonwood from inside the condenser cabinet, rinsed the outdoor coil, tested the capacitor and contactor, and inspected electrical connections at the disconnect. Flushed the condensate drain with treatment solution, replaced the return air filter, and verified supply and return temperature differential during a full cooling cycle.
On arrival, customer is concerned that the ductwork in the attic was split and blowing cold air into the attic. Upon my investigation, I found the ductwork to be split at a previous splice. Informed customer of my findings and recommended replacing the entire run. Customer agreed and wants whole run replaced. The office will call and schedule a date and time to return and perform the repair. I placed a temporary patch on the ductwork to keep the customer cooling until then.
On my arrival, the customer was concerned that the indoor unit was running, but not blowing cold air.

I installed iFlo pro with 6 month drain pan solution, redid the thermostat wiring to make it more uniform, installed new SS1 & SS3 float switches, redid the drain line and added a vent after the p-trap. I tested the systems operations and set the iFlo pro up to find out that the iFlo was not getting external power and was only running off of battery power. I checked proper voltage coming to the iFlo and it had 26 volts being supplied to it. We will be returning to install and new head and verify it is working properly.
Great Job!!
