I know it has to have a new concentric venting system installed, I believe it needs new plenums ( mine are rusty but both of these require extra work , so someHVAC persons are saying I do not need either!! RED FLAG THERE. Also, it will need a new drain using PVCP ?? Piping run maybe two, depending on where my evep coil drain is conected (here in TN they use to run them in with the septic lines, now they cannot be run through that way), Lastly I am not where or what these things do beides hold water but I was told It needs a filter rack and new filter base safety pan. THATSSS it that is all I know about this stuff aside from the fact that nothing up there is to code thus far LOL. !!
"I have a 40 year old home. 53 Air cleaned my AC ducts and vents and added insulation necessary to bring my insulation up to about 18". The work went quickly and there was no mess when they left. It's too soon to be quantitative, but it appears that my AC may be running less and my dust levels in the house may be lessened. As of now, I am very pleased with the work and with the results and I would recommend 53 Air to friends and colleagues."
I turned on the AC when he was finished and immediately saw black fuzz balls the size of marbles come out of several of the registers. He said that was expected since everything was shaken up. So much for describing the service as cleaning. I paid him and sent him on his way. I cannot imagine that this type of service is worthwhile in anything but a new house. Apparently in old houses such as mine I can expect that using a whole house humidifier in the winter followed by a great AC can loosen the soot. Maybe this is to be expected for the first few weeks of summer each year. I now have lined the inside of the registers with cheesecloth to catch the fuzz. I’ll see if it stops after a couple of weeks.
Duct cleaning is also important for energy saving. The U.S. Department of Energy specifies that almost half of the energy used for heating or cooling a home is wasted due to that contaminants pulled into it. These pollutants make your HVAC system work harder to deliver the desired output and also bring down its longevity. Therefore it is quite essential to get the ducts cleaned periodically.
Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.
