Inspected a non-cooling AC system. Diagnosed failed compressor capacitor, which caused the system to hum but not start. Replaced the capacitor with a manufacturer-approved part, verified amperage draw, and confirmed full system operation after startup. Advised homeowner on signs of capacitor failure for future awareness.
Customer experiencing excessive indoor humidity. Evaluated AC system and confirmed short cycling due to incorrect thermostat settings. Adjusted settings, reprogrammed cycle delays, and educated the customer on proper dehumidification. Also verified condensate pump operation. Conditions improved significantly by end of visit.
Replaced a faulty blower motor capacitor after homeowner noticed reduced airflow. Verified resistance values and capacitor specs before installing a new part. Post-installation testing showed correct RPM and airflow output. Unit back to proper function with quieter operation as well.
Routine check revealed signs of microbial growth in the drain pan. Cleaned with coil-safe disinfectant and installed pan Pure AirX treatment to prevent recurrence. Recommended ongoing IAQ upgrades, including UV light installation and high-efficiency filter system.
Cleaned moldy mini split air handler for garage gym. Removed biological buildup from the blower wheel and coil fins using HVAC-safe cleaner. Advised client to maintain regular cleanings and consider installing a UV air purifier to prevent future issues.
Evaluated a 10-year-old system with a failed condenser fan motor. Quoted for motor replacement, capacitor, and labor. Also noted UV damage on the insulation wrap and recommended replacement for efficiency. Provided pricing and repair timeline so the homeowner could make an informed decision.
Customer had complaints of persistent indoor odors and sinus irritation. I conducted an IAQ inspection and installed a Pure AirX UV light in the air handler to target microbial buildup. Additionally, I treated the drain pan with Pure AirX tablets to prevent bacterial slime and blockages. I also inspected the return plenum for leaks and sealed minor gaps to prevent unfiltered air infiltration. IAQ levels should now improve steadily with active UV sanitation.
Repaired a leaking duct plenum with several gaps around collar connections. Used mastic and mesh tape to seal joints and reinsulated the outer surface. Verified airflow improvements at two supply vents using an anemometer. Reduced conditioned air loss significantly in this zone.
Replaced several sections of deteriorated flex duct in a 20-year-old system. The inner liner had collapsed in two branches, causing airflow restriction. Measured and cut new R-8 insulated duct, sealed all connections with UL-181 mastic tape, and strapped them with reinforced supports. Balanced airflow at the supply registers afterward. Duct system is now fully functional, and static pressure readings confirmed improved efficiency and comfort in all zones.
Repaired a short cycling issue caused by a failed contactor with pitted terminals. Replaced the part, then tested voltage at the control board and capacitor. System now cycles properly with accurate thermostat communication and no voltage drop under load.
While performing routine spring maintenance, I found the condenser fan motor pulling high amps and running hot. Bearings were seizing. Recommended immediate replacement to prevent total system failure. Completed full tune-up including coil cleaning, refrigerant check, and tightening of electrical connections.
Performed a spring AC tune-up. I cleaned the condenser coil, checked refrigerant levels, inspected electrical components, and flushed the condensate drain line. Found slightly low R-410A, so I added 4 oz to bring subcooling into spec. System is now running efficiently.
The customer reached out for an air conditioner replacement after their existing unit began making loud noises and failing to cool the home effectively. We helped them select a high-efficiency system tailored to their home’s size and cooling needs. After removing the old unit, we installed the new condenser, connected the refrigerant lines, sealed the ductwork, and tested the system thoroughly. The new air conditioner now operates quietly and efficiently, providing reliable comfort and improved energy savings throughout the home.
The customer contacted us for an air conditioning replacement after their existing unit began showing signs of wear and frequent breakdowns. We conducted a full assessment and recommended a modern, energy-efficient system that would better meet the cooling demands of their home. After safely removing the old unit, we installed the new system, connected the necessary electrical and refrigerant lines, and calibrated the thermostat for optimal performance. The upgraded AC now provides consistent, reliable cooling with improved efficiency, reducing energy costs and enhancing overall indoor comfort.
The customer contacted us for AC repair after the unit began short cycling and failing to maintain a consistent temperature. During the diagnostic, we found a failing thermostat and a partially clogged air filter that were interfering with system performance. We replaced the thermostat, installed a new filter, and verified that refrigerant levels and airflow were within the correct range. The AC system now runs smoothly and efficiently, keeping the home comfortable while reducing energy waste and the risk of future breakdowns.
Performed a post-install quality check on a new two-stage AC unit. Verified charge, duct static pressure, and airflow distribution. System running optimally with lower energy draw.
During a routine tune-up, discovered a small refrigerant leak at the Schrader valve. Replaced the valve core, recharged refrigerant, and verified no further leaks. System cooling properly again.
Customer reported weak airflow in the master bedroom. Upon inspection, found a partially collapsed section of ductwork restricting airflow. Repaired the duct and balanced the system. Airflow restored, and the home is now cooling evenly.
Executed a spring AC tune-up. Cleaned evaporator coil, checked condensate drain line for obstructions, and verified proper subcooling and superheat. System prepared for the upcoming cooling season.
Installed a new Lennox Merit Series ML17XP1 air conditioning unit to replace an aging, low-efficiency system. Proper refrigerant charging and airflow adjustments performed to meet Lennox specifications for optimal performance.
Troubleshot a system with poor airflow. Inspection revealed a severely restricted air filter and a partially collapsed return air duct. Replacing the filter and repairing the ductwork significantly improved system performance and efficiency.
Finished a residential HVAC system experiencing intermittent blower motor failure. Diagnosis indicated a failing capacitor. Replacement with a like-for-like 5uF capacitor restored proper airflow. System amperage draw now within manufacturer specifications. Regular system checks can identify such issues proactively.
