HVAC Service In Buda, TX

Performing semiannual maintenance on one heat pump heating system. Inspected all Performance, Mechanical and Safety Systems. Found everything to be operating within the manufacture’s specifications for operation. Homeowner changed filter prior to us arriving and all Ultra-Violet lights are turned on and working to specifications.

Performed service diagnostic. Diagnostic found that the start assist had failed. Options for repair were presented to customer and they chose to have the start assist replaced and join our maintenance plan. Repair was completed. Electrical disconnect confirmed in and on. System was running at the time of departure.

Performed semiannual maintenance on one heating system located in the attic. Tested all Performance, Mechanical and Safety Systems. Verified everything was operating within manufacture’s specifications for operation. Everything is working at this time.

Performed semiannual maintenance on one heat pump heating system. Inspected all Performance, Mechanical and Safety Systems. Found everything to be operating within manufacture’s specifications for operation.

Replaced supply plenum and installed new I-boxes. Also added balancing dampers at takeoffs and sealed all pressure points with air lock. System operating at this time.

Performed heat check on two systems. Upstairs unit had a dirty blower wheel, and the inducer fan motor was overamping. No other major issues were found. Drain lines were cleared and treated. Options for repair were presented to customer and they chose to have the inducer motor replaced and have the blower wheel cleaned. Repair was completed. System was function checked and the system was running at the time of departure.

Performed semiannual maintenance on one heating system. Tested all Performance, Mechanical and Safety Systems. Verified everything was operating within manufacture’s specifications for operation. I did recommend replacement of the flue pipe to bring to correct sizing, as the current flue exhaust pipe is too large in diameter causing the flue gases to cool off and start to form condensation running back down into the furnace.

Trip 1 - Performed semiannual maintenance. Inspected all Performance, Mechanical and Safety Systems. Upon inspection of the indoor air handler, I noticed substantial amounts of oil residue on the refrigerant line attached to the indoor coil. I used my electronic leak detector and bubbles and found a small pinhole leak along the refrigerant lines. Verified leak multiple times and did notice the refrigerant charge to be below manufacture’s guidelines for operation. Recommended repair of leak and recharging of system back to manufacture’s specifications for operation to return system back to 100% cooling/heating capacity. Changed filter with homeowner supply Perfect Fit Filter. Trip 2 - Repaired leaking refrigerant line, pressure tested with high flow nitrogen, and pulled a deep vacuum on the refrigerant system. Recharged system back to manufacture’s specifications. System is operational and running at 8° of subcooling.

Inspected all Performance, Mechanical and Safety Systems for the downstairs cooling system. Found the outdoor run capacitor to have fallen below value not allowing for the compressor to turn on and pump refrigerant through the indoor cooling coil. Also noted two supply ducts have been chewed through. One duct has been chewed fully through the inner liner, and the other has been chewed through the outer liner and insulation. Spoke with homeowner and they have decided to have the outdoor run capacitor replaced. They also decided to have me seal up the torn duct work as best as possible.

Performed semiannual maintenance. Inspected all Performance, Mechanical and Safety Systems. Verified everything was operating within manufacture’s specifications for operation.

On arrival I found upstairs drain line backed up. Also found condensation inside the emergency drain pan. Removed water from pan. Flushed and treated drain line and primary pan with drain treatment. Did inform homeowner that the outside drain line extension into the yard needs to be upsized since there are two systems feeding into one three-quarter inch pipe as this is contributing to the blockage issue. Also recommend installing a ceiling saver water safety switch into the upstairs unit. The secondary port was never plugged and when the primary line becomes backed up, condensation will flow into emergency pan.

Performed maintenance on the AC system. I cleared, treated, and tested the drain line. I cleaned the condenser. System is operational at this time.

Inspected all Performance, Mechanical and Safety Systems. Found the indoor fan control board has failed. Spoke with homeowner and we have decided to move forward with replacement of the indoor board to restore system back to operational status. Installed new fan control board, cycled the cooling system and verified everything was working within manufacture’s specifications for operation.

Inspected all Performance, Mechanical and Safety Systems. Found the outdoor run capacitor to be below manufacture’s value. Also noted the outdoor exhaust motor and starter to be operating outside manufacture’s specifications for operation. Discussed repair options with homeowner and they have decided to move forward with replacement of the outdoor run capacitor and declined repair of the motor and starter.

Inspected all Performance, Mechanical and Safety Systems. Found the outdoor starter failed due to ants blocking the electrical contacts. Installed new contactor, removed all ants and cockroaches and treated with JS spray to help deter ants from returning. Tested all systems. Inspected all other systems and found everything to be working at this time.

Performed AC cool check on a one-year-old Carrier gas system. Checked electrical, mechanical, safety, and performance of the system. No major issues were found. Drain line was cleared and treated. Condenser coil cleaned. Electrical disconnect confirmed in and on. System set to 72 degrees per customer. System was running at the time of departure.

Performed semiannual maintenance on one comfort cooling system. Tested all Performance, Mechanical and Safety Systems. Found everything to be working within manufacture’s specifications for operation. Homeowner did report he noticed condensation inside the furnace closet and on the coil panel. We found the panel to be slightly bent, allowing for the cold air to mix with the combustible air vent. This caused excessive condensation inside closet. I double sealed the panel and suction line to prevent cold air from mixing inside closet.

Performed semiannual maintenance on one comfort cooling system. Inspected all Performance, Mechanical and Safety Systems. Flushed and treated the primary condensate removal drain. Found everything to be working within manufacture’s specifications for operation.

Diagnosed a large leak in the condensing coil. I found signs of refrigerant oil on the condensing coil on the condenser on the driveway side of the house (this is the East side of the house.) I was also able to identify the leak with my leak detector. I gave the client her options, and she chose to have the coil replaced since it is still under the parts warranty. Replaced outdoor condensing coil and in line filter dryer. Pressure tested with dry nitrogen and pulled a vacuum on the system. Weighed in factory charge and check operation of system. System operational at this time.

Performed maintenance on the AC system. I cleared and treated the drain lines. Cleaned the condenser coil. System is operational at this time.
