HVAC Service In Buda, TX

Performed semiannual maintenance on one heat pump cooling system. Inspected all Performance, Mechanical and Safety Systems. I completed a full check of the system. Cleaned and removed all leaves from the base of the condenser. I did notice signs of rust on the base pan but no through and through holes are appearing. Tested all mechanical components and ensured proper operation. Everything is working at this time.

The drain lines were then treated. The blower wheels are clean, and the blower motor capacitors are within value. The wiring on both systems is tight and in good condition. The condenser fan motors and contactors are in good condition. The refrigerant charge is within factory specifications on both systems. The capacitors for the condenser units are within value. Systems were running at the time of departure.

Performed AC cool check. Checked electrical, mechanical, safety, and performance of the system. The drain line was cleared, and flow tested with two gallons of water. The drain line was treated.

On arrival, I found that the emergency water safety switch was tripped due to a restricted primary drain line. I blew out the line multiple times, and used hot water from the sink to help loosen up any additional clogs in the line. Also cleaned out the internal drain pan to remove all the sitting blockages inside the coil pan. I then added in a drain treatment to the internal drain pan and the primary drain line which will help break down any buildup and help make the drain line slippery to allow for easier drainage. Everything is working at this time.

Diagnostic found that the drain line was clogged. Water had backed up and tripped the safety switch. The customer was due for a maintenance visit, so I performed a cool check of the system.

The drain line was cleared, and flow tested with two gallons of water and then was treated. The air handler, blower wheel, and evaporator coil are all clean. The wiring is tight and in good condition. The condenser fan motor and contactor are both in good condition. The refrigerant charge is within factory specifications. The capacitor is within value. The condenser coil was cleaned. No major issues were found, and the system is running at the time of departure.

Main House HVAC System: Found the outdoor run capacitor has failed across the FAN terminals and is getting low on the HERM terminal. Installed a new run capacitor in and started the system up. I then found that the refrigerant levels are below the freezing saturation point, with a 45°SH and a negative SC value. Added in 5# of R-410A refrigerant into the system to return to a 12°SH and a 7°SC per the manufacturer charging chart. Performed a leak search and I did find a significant leak in the indoor coil. Everything is working at this time.

Performed semiannual maintenance on one straight cool AC system. Inspected all Performance, Mechanical and Safety systems. Tested and verified all mechanical components were operating within manufacture’s specifications for operation. Homeowner changed out the air filters prior to us arriving for the maintenance. I did go ahead and wash out the outdoor condenser as there were some grass clippings and dust build up between the fins of the coil. Reset filter and service reminders on both thermostats and ensured thermostats were set back to original set points. Everything is working at this time.

Single system cool check completed. The air handler is clean. The drain line was cleared and treated. Both float switches were checked and are operational. I also replaced the filter. The outdoor coils were cleaned. All electrical within manufactures specs. The refrigerant charge is within range. No major issues found at this time.

Master System: Removed the supply and return plenums. Installed a new return plenum. Added a return to the master bedroom and added another to one of the kids’ rooms. Installed new premium supply trunk line and attached the existing supply ducts with dampers. Cleared, flushed and treated the condensate drain line. Guest System: Removed the supply and return plenums. Installed a new return plenum. Added a return to the guest bedroom. Installed an extended supply plenum and attached the existing ducts with dampers. Cleared, flushed and treated the condensate drain. Both systems are operating properly at this time.

Performed AC cool check. Checked electrical, mechanical, safety, and performance for the system. The drain line was cleared, and flow tested with water. I found the connection at the PVC to black hose on the drain line to be loose, so I tightened down the connection. I also treated the drain line. The blower wheel is clean and the capacitor for the blower motor is within value. The condenser fan motor and contactor are both in good condition. The capacitor for the condenser unit is within value. The refrigerant charge is within factory specifications, and the condenser coil was cleaned. No major issues were found, and the system is running at the time of departure.

Performed semiannual maintenance on two AC systems. Inspected all Performance, Mechanical and Safety Systems. Changed out two 4” media filters supplied by the homeowners. Tested and verified everything was operating within manufacture’s specifications for operation. Everything is working at this time.

Performed cooling maintenance on two systems. Checked all electrical, mechanical and performance of the systems. Cleared and treated both drain lines and washed both outdoor coils. I sealed the furnace knockouts with cork tape to prevent any attic air from being pulled into the system. I replaced a high voltage wire nut at the furnace which had a crack on it. I also installed Seal-Tite on the outdoor fan motor wiring for the upstairs system to prevent the wiring from deteriorating. I did find both indoor blower motor capacitors are below value and both outdoor starters are pitted at the contacts. No other major issues were found.
