Customer planning to invest in new system will know for sure this evening

Tech arrived to verify findings of previous company’s diagnosis. Tech confirmed diagnosis was in fact correct. Tech found a failed compressor, cracked heat exchanger, leaking evaporator coil as well as a failed variable speed motor/module and control board. System is 12 years old. Price of repair will outweigh price of replacement. Tech gave details to home warranty company per request, need to have a supervisor come out tomorrow after 12 to give replacement quote. Tech left power to system off. Collected house call fee by card.

Tech found leaking evaporator coil lots of rust and corrosion and outdoor fan motor over amping. Tech also found that heat strip pull out diss connect is bypassed home owner is unsure why, tech inspected pull out is missing tech suspects this is why someone bypassed. Field supervisor out to verify tech didn’t clean system per customer request.

Tech performed two system ESA, tech made recommendations for each unit. Bryant package-tech found bacterial build up in unit and recommended plasma, tech also recommended surge protection to protect major components from power surge and potential lightning strike. Payne package- tech recommended surge protection to protect major components from power surge and potential lightning strike.tech found no issues with system operation at this time. Both systems are back on and operating properly at this time. Customers are interested in adding mini splits to ESA, and said they would add them at next visit due it being TTE at that time. Customers have washable filters.

PERFORMED CMA FILTER CHANGE. FILTER CHANGE COMPLETE. CLEANED 2 MAKE UP AIR SYSTEMS.

Tech found no difficulties at this time. Tech did not enter home per homeowners request

FOUND SYSTEM COMPLETELY FROZEN UPON ARRIVAL. DE-ICED SYSTEM TO BEST OF ABILITY AND MONITORED PRESSURES. DIAGNOSED LOW ON CHARGE. UNABLE TO ACCESS AIR HANDLER AT THIS TIME. LEAK LIKELY WITHIN EVAPORATOR COILS UNABLE TO LOCATE AT CONDENSER. COMPRESSOR READING WITHIN BAD/CAUTION RANGE. COSTLY REPAIRS NOT RECOMMENDED. SPOKE WITH MR. CUPP. HANDED OVER TO CHRIS/COLBY.

System #5 Found a shorted compressor contactor. Resistance value is at 1.5ohms. 5amp fuse needs to be replaced. System #7 needed a disconnect fuse. Amp draws within specs. System #1 Found it on hard lock out upon arrival. Reset it and observed the operation in heat mode and cool mode.system is set on cool mode at the thermostat with a low set point. Thermostat have a locked lock box. Tech suspects a low r410a charge and recommends a leak search during the next service visit. System #6 has a clogged condenser coil. Needs to be cleaned. System #3 refrigerant levels within specs. System #8 found it on hard lock out, reset it to test it and automatically started up in cool mode. Refrigerant levels within specs, tech does recommend replacing the filters more frequently, thermostats are locked at the box. Currently set to 66 cooling. Tech recommends to adjust the temperature accordingly and not alter the temperature as much. Most of the Mechanical rooms are locked. Repairs were taken car

Performed CMA inspection on 8 split systems. Air handlers 7 & 8 had been mislabeled prior. Corrected as appropriate. -Split System 1: Observed fault flash code 4 “hard lockout.” Performed hard reset of system to operate condenser. No keys on site to access air handler in mechanical room. Regional maintenance is in control of keys. -Split System 2: Sure switch in air handler primary drain trap not connected and wiring missing. Recommend replacement of sure switch. Provided estimate $186.30. -Split System 3: Observed fault flash code 4 “hard lockout.” Performed hard reset of system to operate condenser. System continued to operate without fault codes throughout inspection. Observed high negative pressure in return duct flex due to poor air flow. Air filter in poor condition and return located in closed room. Significant suction at door to storage room as a result. Recommend more frequent replacement of air filter. System would benefit from relocation of return duct. -Split System 4:

Tech performed CMA FULL SERVICE ON 3 Gas Package Units, 2 Make Up Air Units, and 4 Exhaust Fans. Upon inspection tech found all 3 gas packs with low gas pressure feeding the furnaces on each system. Tech adjusted pressure successfully on systems 1 and 2 but was unable to get the correct pressure on system #3 due to running out of trim on the gas valve. Tech also found ODF #2 on system #3 not operational as well as a large hole in the condenser coil. Due to this and the age and condition of the system tech recommends replacement. Systems 1 and 2 as well as all make up air and exhaust systems are operating properly at this time. Tech has attached system performance reports to this invoice.

Performed routine maintenance per energy savings agreement. Technician found no challenges at todays visit. System was cleaned thoroughly and all electrics tested within spec. System is operating normally in heating and cooling modes. Delta t observed during maintenance today was 20 degrees. Tech did follow up on Plasma Air Purifier from last maintenance. Customer declined this time as well, however tech did add it to an estimate should they decide to make the purchase.

Performed ESA.

Tech washed and serviced unit and found no challenges at this time. Unit is cooling properly with a delta t of 21 with a return of 74 and a supply of 53

Re secure return ducts at air handler 7 in attic per prior approval. Replace weak fan capacitor on heat pumps 2, 3, 6 & 8 per prior approval.

Tech completed diagnostic. Found relay board not energizing y2 . Homeowner stated he will have company who installed relay board this year run a warranty part replacement or thermostat reprogramming Homeowner will call Monday if he wants coil replaced. At this time unsure if he wants repaired

Tech found system low on charge and not staging into second stage Tech temporarily bypassed staging by connecting y1 to y2 at outdoor unit Thermostat is a communicating system that likely goes under house and translates to outdoor unit. Due to dissatisfaction tech added refrigerant and we will need to schedule appointment when it’s not raining. Need to confirm leak is in evap coil and need to open com waterproof box to confirm controls are set up correctly.
