Our technician was fantastic. Very friendly.
Every Interstate experience I’ve had has been great ... from scheduling appointments to the actual service calls. Everyone is friendly, knowledgeable, reliable, and responsive. And my HVAC system has been working like a charm. Highly recommend!
Quick follow up to a problem. Professional and polite. Showed concern for our home.
Brandon Nelson is very friendly, professional and efficient. He explained to me what the problem was, tested my A/C to make sure the problem was resolved.
At first the tech said I needed to have freon added for $149. and also cost of a diagnosis call, $89.99. I told him I had already a diagnosis call and nothing was indicated as being needed and his office had said that there would be no charge for the diagnosis. I told him I would think on the freon. Brandon called back and said he went ahead and added nine oz. of freon and wouldn't charge for the diagnosis call. There was no charge for the service. That restored my faith in Interstate and the owners, Kai and Jamie.
Prompt, quick, respectful, professional. Couldn’t ask for more.
I came out to call. Customer said they are selling the house and the buyers had an inspector out to inspect the house. He wrote several things down. I went over each listing to verify any problems. I washed the condenser coil thoroughly. System is operating at a 17 degree subcooling and suggests 15, which has a 3 degree swing. The air leak by the condensation line has been filled with silicone. Delta T air temps are averaging 10-11 on farthest runs and 12-13 on the closer runs. The air vents closest to the furnace closet are going to have cooler air than some of the longer runs, but the system overall is cooling and operating properly within manufactured specifications.
Came out to call. Customer said water was dripping from drain on back porch. I had to check drain and emergency drain pan. System is hard to access, so I had to access it through garage. I vacuumed out drain pan of system. Cleaned out drain, and vacuumed out remaining water. Evaporator coil has a lot of air leaks, and wasnâ€™t sealed off that well. I recommended replacing the coil to get a better fit and less air leaks. The air leaks are also creating moisture. Customer will get back to me about it.
Arrived to call back performed system evaluation. Found unit pretty low on r22 we service system the other day. Found stuck valve stem unit leaked out thru highside valve stem. Replaced both valve stem as a precaution. Charged unit with r22 refrigerant. All work above performed as a call back no charges to customer. Furnace blower is getting pretty noisy this may cause problems in future system is cooling at this time.
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 ACâ€™s are cooling properly at
Performed non club tune up. Washed condenser. Customer recently replaced filters. Blower and evaporator are pretty clean. Test capacitor and motor amp draw. Test compressor amp draw. All amp draw in range. Refrigerant levels are in range. System is cooling as designed at this time. House could use whirlybird or powered roof vents to help cool better on hot days. Ac cooling well at this time. Customer had 25 dollar credit applied towards balance.
Arrived to no cool service call and performed system evaluation. System is getting older and could use replacing. Found system low on r22. Spoke options with customer and gave estimate to replace. At this time customer chose to add refrigerant. With customer approval I added 2lbs of refrigerant to system. Super heat in range. System is cooling at this time. Due to age and condition of system can give no guarantees on refrigerant. Suggest system replacement be considered in future.
Performed preventative maintenance on AC system. Customer already changed filters. I inspected the blower assembly, electrical components, evaporator coil, drain, and overall condition of equipment in closet. Cleaned condenser coil thoroughly. Checked and tested thermostat operation, wiring, capacitor, contactor, compressor, fan motor, amps, temperatures and pressures of condenser unit.
Arrived to condensation leak service call for minisplit. Found dirty drain pan and drain line. Cleaned drain line and washed filters. Tested drain with about 1 gallon of water drain is working at this time. Condenser coil was washed and unit is cooling at this time.
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. See attached photo.
Arrived to service call performed system evaluation on condenser. Tested capacitor and motor amp draw test compressor amp draw refrigerant levels are in range. Was unable to recreate noise. Collected service fee will leave ticket open for now. Unable to test indoor to to covid 19 concerns. Office needs to call in afternoon to collect payment.
I arrived for a no cool call. I first inspected the indoor system and found the evaporator coil to be clean but extremely rusted and I found oil on the front side of the coil. I inspected the condenser and found the the system to be running but running low on refegerant. This system was installed in 2016 and the evaporator coil was replaced In 2018 due to the evaporator coils leaking. I gave homeowners options on replacing the evaporator coil or just adding refegerant at this time. The homeowner decided to try and contact concord to see if they can get the system repaired for no cost.
Came out to call. Customer said ac wasnâ€™t working. He already changed the capacitor and washed the unit and it still wasnâ€™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 wasnâ€™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.
Came out to call. Customer said she had someone out to fix the wiring she accidentally cut with the mower. The system still wasnâ€™t working properly. I checked system over and found the furnace is from 83, and has a fan relay transformer combo. I had power to the transformer but not 24 volts. OG&E thermostat wasnâ€™t operating, and went blank after I checked wiring. I do not have this part available and need to pick up from a supply house. Told customer Iâ€™d get one tomorrow and come back to put it in. 07JUL20-Installed the transformer/relay combo. Wired it in and the thermostat went blank. Installed a new discounted thermostat. I found there was a loose wire behind the relay. I retightened all the wire nuts. Tested the system in heat, fan and AC. All working 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
