Performed single system cooling maintenance. I checked amps, capacitor filter, electrical, cleanliness, drains, temperature difference, refrigerant temperature, washed the outdoor unit with water. The system is cooling within manufacture specifications. The customer and I spoke about the son’s room not cooling very well. I inspected the ducts involving the son’s room. There is a duct feeding what appears to be 3 ducts. This will never work properly. I provided pricing to run a direct duct to the system to feed that room. Per the air sample, the home has higher than normal particulate value. I spoke with the customer about adding an air scrubber to produce negative ions in the home. This will allow the particulates to clump better allowing the filter to catch it. Some particles are too small for the filter to filtrate it. I spoke with the customer about the importance of back-up water safety switches and drain treatment to help keep the home safe from potential water damage. I info
Arrived on site, customer stated all was well with system. Although, she had not run the cooling yet for the year. Began evaluation of system on the outdoor condenser. Contactor tested within range, and compressor start as well as run amps were within specs. The outdoor fan however, was showing high start amps. Which could indicate that the motor is close to failing. At the indoor unit I noticed some corrosion in the emergency drain pan that could have been from previously. Noted previous work blowout valve will continue to monitor. No water safety switch on primary drain line. Blower start and run amps tested within range. Return and supply split 20 degrees. System left in good working condition. Recommendation 1. Air Scrubber-to assist in cleaning the air in the home through ionization of dust particles so that more is captured by the filter as well as kill growth around the coil
I performed a heating maintenance on a 2022 communicating zoned gas heat system. Due to the time of service, I checked a little bit of the cooling portion as well. I checked amps, electrical, cleanliness, drains, and safeties. The system is performing well with some necessary recommendations. Recommendations 1. The out door unit could use a chemical cleaning to prepare it for summer time. This ensures the outdoor unit can breathe and perform efficiently. 2. During summer, the unit will produce far more water. It is advised to install a water safety switch and perform a drain treatment. This will prepare it for the large amounts of water production and give the customer some sort of peace of mind knowing it has a safety switch to protect against potential water damage.
Performed single system heating maintenance on a 2024 gas furnace. The system has a 10 year labor warranty. I checked amps, capacitor, replaced the filter, flushed the drain with water only, examined the cleanliness, and tested the safeties. The system is heating to manufacture specifications. I recommend that a surge protector and air scrubber be added to the system to assist in maintaining cleanliness and to protect the components inside of the furnace. Also, I recommend a drain treatment with chemicals to prepare the drain for cooling season.
Performed a visual inspection of HVAC system and found AC and furnace running at the same time. Homeowner stated that temperature was unstable for both upstairs and downstairs. I checked the furnace and found jumper wire on Y1 and R causing the furnace to run continuously. Homeowner also stated that a strange sound was coming from the heat pump while in cooling mode. Further assessment determined that the high temperature from the furnace across the evaporator coil and refrigerant was the cause of the strain cell. Once the air temperature cooled down across the evaporator coil, the strainer sound started to dissipate. The high air temperature across the refrigerant coil was the issue. I will contact the homeowner within the next 48 hours to ensure issue has been resolved. No further issues at this time.
Performed system maintenance on 2024 5Ton multi stage zoned Trane system. Unit is running as it’s designed to with all amps reading properly, flame sensor is clean, all electrical panels and connections are secured and dust and debris free, as well as outdoor unit coils are clean and everything is running as it should at this time
upon arrival noticed fan motor continuously running without shutting off. I disconnected thermostat to ensure the thermostat wasn’t bad or possible bed wiring everything checked out as it should. Checked fan relay, noticed relay stuck open, giving a constant call for the fan to run.
Preformed system maintenance. Unit is a Reehm all electric air handler, with straight cool condensing unit. The system is running as it should at this time. Unfortunately, without an emergency shut off, the unit is out of code. There needs to be a safety float switch to bring unit up to code . I’ve provided 3 types of emergency shut off. Only recommend putting in 1 of the 3 to bring unit up to code. Also would recommend chemical clean on outdoor condensing unit. As it’s full of debris, causing the compressor and fan motor to work harder than they should and/or could possibly lead to premature failure on one of them if not both.
Performed operational fall inspection on HVAC system. System is running according to manufacturer specs without issue and supplying heating to residence. Furnace and condensing unit are in pristine condition, homeowner is pleased with newly installed HVAC system.
Came out for 1 system maintenance. Upon arrival started at tstat turning system from ac to heat. System is a gas horizontal zoned carrier system. Insulation is good ducts are in good condition. Checked the heating sequence of the unit. Burners are firing properly all safeties are operating as designed by manufacture specifications. Did notice rust in secondary drain pan and no float safety switch on system recommend adding to prevent water damaged also recommend adding blowout kit and pan treatment into system to help keep drain lines clear. Filter is due to be changed 20x25x4. Evap coil has substantial amount of rust on coil. On outside unit system was rough on start up recommend adding hard start kit to increase efficiency and longevity of unit. Thank you for your time.

AC system / unit down not working in Little Elm. Started diagnostic at the condenser unit, tested compressor/ condenser fan motor capacitor, didn’t have signal to cool. Noticed the blower wheel wasn’t centered properly and it was rubbing metal to metal, tested blower capacitor (tested ok). Replace the blower, after removing the blower motor we noticed the blower wheel wasn’t properly installed, blower motor wiring got extremely damage. Finished repair with homeowners authorization.
AC check up / tuned up in little Elm north Dallas. Performed cooling maintenance. Checked amps, refrigerant, filter, condensate drain, cleanliness, and temperature differential. Found the condensate drain appeared clogged. Turns out it is making more water than what can drain down the primary due to a slow drain and clear the sink.
Hail Damage on air conditioning system, Adon Complete went through the back gate found Goodman condenser on side of the house. Combed out two different sides of condenser where I saw fins smashed down and rinsed off your unit with water to get all the Cottonwood and dust and debris out of there to help with efficiency.
Heating HVAC maintenance Performed one time tune-up on 1 system (zoned U/S & D/S). Client reported hot/cold spots, checked ductwork and found all connections are “Y†connections, unable to add dampers to better control airflow. Noticed a couple areas of concern such as blower assembly is holding dust which reduces efficiency and longevity of motor as well as missing in-line float switch for water damage prevention. Client is using fiberglass filtration which only catches large particles, recommend using pleated filtration for future use. (20x25x1)
Found u/s zone damper motor stuck closed when call for cooling, d/s zone damper motor operating properly during call for cooling. When d/s thermostat satisfies and u/s thermostat calling unit pressures drop below freezing and cause coil to freeze up. Customer does not want to move forward at this time, plans to contact home warranty company.
