I came out for an AC maintenance. I washed the condenser coil and changed the filters. I checked the blower, drain, evap coil, capacitors, contactor and all wiring. I cycled the ac and checked all temps, amps and charge. All working properly.

I came out for a no cool. The system is less than 2 years old. I checked the system over and everything looks ok. The thermostat was off. I turned the stat on and everything came in and cycled correctly. Charge is right on and there’s a 21 degree temp split. The top filter on the air handler wasn’t very dirty, but was installed incorrectly and had been pulled out of its frame. I installed a new filter. All working well.

I came back out for a condensate leak. The P-trap on the coil was clogged again. That system doesn’t need a trap. So I cut in out, blew the lines out again and reconnected the drain without a P-trap. I ran water through the drain and it didn’t back up at all. All working properly. The drain does tie in to some sort of pipe in the attic that is copper or iron pipe and I can’t trace where it goes. Those do have a tendency to clog, if there’s continual drain issues I recommend installing a condensate pump or running the drain completely in PVC.

Arrived for failed flue inspection. Customer mention that his home was not cooling as well as he would like. Corrected flue slope. Check coil temperature 51 degrees. Checked closet temperature where customer stated the temperature was ideal. 55 degrees. Then checked temperature at master supply. 62 degrees. I did notice that there was less air flow at the master register. I recommend adding dampers to the system to balance the air flow. Four 6” starts and dampers One 8” start and damper One 10” start and damper. The plenum is metal and has decent room for static pressure. Coil 50 degrees Closet 55 degrees Master 62 degrees.

I came back out for a not cooling well on the front office system. The system is cooling as well as it can. The SH was at 15 and calling for 13. There’s a 15-17 temp split between the supply and return. The system is 17 years old and ductwork is undersized. It needs 800cfm and has only 500cfm on the return side and 470 on the supply. The center AC on the main building climate controlled storage area keeps tripping a breaker. I checked the system over and found the compressor locked up. It tries to start pulling 155+ amps then trips the breaker. This is the same type and size as the AC on storage building B that has a burnt out compressor. I recommend replacing the ACs, flushing the coils and swapping out the pistons. I gave a price for a compressor only and for the AC replacement. Compressor only has 1yr parts and labor warranty AC replacement has 10 year parts/compressor and 1yr labor warranty.

Blue SPP summer ac tune up. Filter was recently replaced and customer asked about previous recommendation from Technician, Isaac, to get more airflow into living room. Supply vent was placed 4 feet from main return. This causes the air from the supply to get pulled back towards the return instead of giving it time to circulate jn the living room properly. Recommend cutting in 8” supply near windows jn living space and increasing return to 18” duct to give system sufficient air for blower motor. See attached estimate. Washed condenser thoroughly, cleaned contactor points and capacitors from bugs And dirt having overrun the condenser control area. Checked furnace and blower. Checked capacitors. Checked contactor and volt drop. Checked amp draws. Evaporator coil was turned backwards and is hard to reach to properly inspect, but did make sure condensate line was draining properly. AC system operating great at this time. Left customer with fresh 14x24 filter that comes with Blue plan.

I arrived for a non member tune up. I first spoke with the homeowner and and the main issue was the system runs all the time and dose not drop in temperature. I first inspect the system compared to the home and found a 2 ton systems on a 3.5 ton home. I explained that a ac system needs 400 sq ft to properly cool a home efficiently per the electric/run time of the system. I would expect this system to have a short life due to the system running longer to keep the home cool. A 3.5 ton system will cool the home to the same temperature with less run time and less money spent to cool the home. I inspected the system located in the attic and found the evaporator coil to be clean and all electrical components to be work properly. I inspected the condenser and found the all electrical components to be working properly but the system was running low on R410A. I recommend to have the system leak checked and charged properly to get the systems working correctly. The homeowner decided to just add

I arrived for a non member special tune up. I first spoke with the homeowner and found no major issues with the systems operation. I first inspected the system located in the attic and found the secondary drain pan to be completely full of water. I also found the main drain to be clogged up. I checked all electrical components in the furnace and found the capacitor to be non readable and leaking oil. I then checked the condenser and found the condenser coil to be stopped up. I checked the electrical components and found the contactor to be extremely black and pitted. I also checked the systems refrigerant charge and found the system to be running low on R22. I made all issues aware to the homeowner and explained the functions of the components and how the parts keep the system running to the best of its abilities. We decided to replace all recommended components and to add what refegerant was necessary to get the system running properly. I first removed the p-trap from the positive pre

I came out for a tune up. He said the system is running but the airflow is minimal in some vents and won’t cool the house properly.i washed the condenser coil. I checked the system over and all operations. The system is working as well as it can. There are multiple issues that are keeping it running and cooling properly. The system 8s undersized for the house and the attic has very little insulation. The furnace and coil and older and fairly dirty. Also the supply ducts are undersized and very poorly ran. There’s expose elbows, improper couplings and the duct work is not strapped correctly. I recommend replacing the system and reductions the entire house, so it’s sized, ran and payed out properly. Then have more attic insulation blown in.

Arrived to not cooling well service call performed system evaluation on 2008 carrier system. Changed filter. Amp draws in range. Found system a little low on r410a. Spoke options with customer. Customer chose to add refrigerant to system. With customer approval I added 2lbs refrigerant to system. System running at 12 subcooling per carrier specifications. System is cooling at this time. No guarantee on refrigerant. Compressor did over heat during service call most likely from running a while low on refrigerant. It is possible running low on refrigerant for awhile could have caused damage to system. If compressor was to fail in next 30 days and customer has us replace condenser todays balance will apply towards unit.

Came out to call. Customer said both his units had froze up since the start of this week. He turned the upstairs system off to let it thaw but still ran the downstairs. The downstairs unit was frozen over. Both the upstairs and downstairs filters were dirty. Customer will replace them. With customers permission, I ran the heater on downstairs unit to thaw it out while I checked upstairs unit. I cycled upstairs unit on and found it low on charge. The upstairs equipment is original to the home (1996), and there is a leak in the system. I discussed with customer about refrigerant needed and other options, like replacement of system. Customer wanted to just add the refrigerant for now and look into replacing the system later this year. I added 1.6lbs of R-22 to unit to get correct superheat. After I checked the upstairs system, I cycled downstairs unit on and checked charge. System was slightly off on charge. Customer had me add 1lb to downstairs system. Both AC’s are cooling properly at

Commercial warehouse site with 6 rooftop package units and overhead ducts in conditioned space. Customer wanted to see if we could remove insulation to bare metal, and after looking at it we cannot do it in a cost effective manner and guarantee removing all Insulation, recommend having a senior technician out to give a commercial quote to replace each ductwork trunkline and ensure no contaminates would be in system when they become operational.

Came out to call. Customer said ac wasn’t working. He already changed the capacitor and washed the unit and it still wasn’t working. System is an 8 year old Lennox unit. It has a high pressure switch reset. I reset the switch and the system came on, but the compressor wasn’t kicking in. I recommended a hard start kit and washing the condenser. Customer had me install hard start kit. Compressor kicked on. I checked amps temperatures and pressures. System is cooling properly.

I arrived for a silver member ac pm. I first inspected the indoor system and found the evaporator coil to be clean and in good condition. I also found the filter to be new and in good condition. I inspected the condenser and found the coils to be completely stopped up and the contactor to be black and starting to pit. I recommend to replace the contactor as a preventative repair. The homeowners agreed to replace the contactor at this time. I disastrously the conditioner and clean the coils and replace the contactor. I cycled the system on and check the operation and found no other issues at this time.

Per previous AC tune up earlier today, changed 3 10x20x1 pleated filters to go with duct cleaning, also changed dual capacitor for compressor. Unable to clean evaporator coil or blower wheel because of location if furnace, half a wall is blocking from removing components for proper cleaning. Customer will wait and have system changed. Layed drop seers where necessary, shop vacced out heavy sand and construction debris from supplies. Duct cleaned 14 supplies upstairs and downstairs with 3 to 4 passes each. Sealed 2 supplies in NE downstairs kids bedroom that were rusting out and living room supply on north side by main entrance. Duct cleaned returns with 10 passes each, upstairs returns had a 90 degree bend about 15-18 feet in that I could not get past. Vacuumed up excess debris and fogged in hospital grade disinfectant spray. Replaced grills and vents. Found some residual mud in the central part of the ductwork, and some fill sand has come into the plenum under the furnace and evap co

I came out for a not cooling well. He added 4lbs of r22 last year. And the system isn’t keeping up in the very hot days. I checked the system over and it running at a 2 SH and calling for 6. So the charge is good. The roof only has 2-12” whirley birds and the attic size requires 4-12” or 3-14”. The system is getting older and return ducts are undersized as well. All those are combining to keep the system from cooling properly.

Came out to call. Customer explained to me that he had a company come out to put in a new AC and coil for him close to 2 years ago. Recently the system hasn’t been cooling and he called them out again to check it. Told him it was low on refrigerant, the evaporator coil has a leak, needs replaced, and the coil they installed only had a 1 year warranty on it. Customer had me out for second opinion. I checked system over and found the the upstairs air handler to be a 5 ton and he was told it was a 4 ton. The outside ac was replaced and it’s a 4 ton. The condition of the A coil doesn’t seem right for less than 2 years old. I made homeowner aware of the tonnage and condition of the evaporator coil. Customer said the company didn’t have records for the new coil they supposedly installed. The Airhandler itself was installed in 2004. The evap coil has severe rust damage and needs to be replaced. Told customer I’d get him pricing and availability of the evaporator coil in the morning.

Arrived to service call and performed system evaluation on condensation leak. Found drain line clear and most water in evaporator coil evaporated. Customer recently changed filters yesterday. Condenser was dirty. I think that filters were dirty and a mix between that and dirty condenser had caused unit to freeze up. Suggest tune up to clean condenser. Customer chose to have tune up performed. Washed condenser. Test capacitor and motor amp draw. Refrigerant levels are in range. System is cooling at this time suggest filter replacement every 60 days.

I came out for a not cooling well. They said the system has never really been able to keep up in the heat of the summer. The compressor doesn’t sound like it’s running exactly right. I checked the system over and it’s got a higher suction pressure, lower head pressure and low SH and SC. The bulb is in tight and insulated. I tried a pump down test and the system would barely pump down at all. The compressor is bad and not compressing properly. I recommend replacing the compressor or the AC. The system only had a 5yr warranty in it. Compressor only has a 1yr part and labor warranty. AC replacement has 10yr part and 1yr labor warranty.
