Comments (5)Jt Some questions please. What is your location? What size home living area? What size furnace and eff are you replacing? What size AC are you replacing? I would like to know the exact mdl number evap coil for each quote. What thermostat is proposed for the Carrier quote? That is a big difference between the 96% eff Carrier furnace and the 80% eff Trane furnace-both 60 K input. That would be about 56 KBTUs output on the Carrier and about 48 KBTUs on the Trane. Not insignificant. I don't care for some shortcuts that homeowners make particularly on reusing linesets and using existing thermostats that shortchange a nice furnace's operational capability. Post back with the info requested. IMO...See MoreCorrosion on newly installed HVAC heat exchanger and coil
Comments (34)Hi, I am the one who originally started this thread and I wanted to give a quick update: Our cotated coil has been working fine. No white flakes at all. The original issue may have been due to the fact that we are in a suprisingly humid micro climate, our coil is located in an unconditioned crawl space, and our AC system may have been oversized. Therefore, salt deposits/corrosion started to accumulate on the bare aluminum of the originally installed coil and started to flake off when we switched from colling to heating, as the warm air was passing the coil. To my knowledge, the white flakes were insoluble salt/corrosion deposits on the coil and therefore are not toxic! Anyway, if you have the same issue of white flakes comig off your aluminum coil, coating it may do the trick. I did not want that coating to be done on site and requested it to be done at the factory to a brand new coil in a more controlled environment in order to achieve the best results. One important note: if you decide to get a coated coil cleaned, do NOT use standard coil cleaners as they will destroy the coating. You need to use a specially forumlated ph-neutral cleaner. Most coil cleaners are not ph-neutral. I hope this helps....See MoreInstalled HVAC dilemma
Comments (15)I think you have purchased this AeroSys Sytem. I am not an expert on these, but I understand the limitations you are facing with your coop. If you read the document it says the equipment has a 2 year warranty. I don't know how this warranty works or if the installer has to register the equipment with the manufacturer. I think your contractor hired the lowest cost HVAC installer he could find. This contractor did a poor installation job of installing a piece of equipment that is discontinued. He probably got it at a bargain price. I am very suspicious about the story you were given about missing insulation. HVAC equipment comes with a factory charge. It is the job of the installer to install the proper amount of refrigerant when it is installed. It may have been too cold in March when it was installed to do set the proper charge, so we will give them the benefit of the doubt. But there should have been a follow up visit to complete the installation. I don't understand how the AeroSys equipment can be replaced under warranty with another brand of equipment. The distributor is not going to take back equipment without a thorough investigation of the problem, so I am suspicious of what you are being told. My recommendation is to talk to the contractor about the equipment and labor warranty. If you says you are cover until March 2020, then I recommend keeping the equipment for this summer and see if it performs well. HVAC equipment is constantly changing so I would not get very concerned if the model you have is not longer made. It is fine if it was installed properly, which quite honestly I think is the real the problem. I would be inclined to get another HVAC company involved for a second opinion and give the bill to the contractor....See MoreHVAC installed before shingles? What constitutes being “dried in?”
Comments (5)Shouldn't be a problem with the sheet metal. But "no" to the HVAC equipment. You should have the build well secured--locks, lights, alarms. Shingles and underlayment should go on pronto....See Moremr_havac
