I think that the coding and permit industry is a joke!! They will not allow the homeowner to apply for the permit it has to be the licenced contractor. It would make since to allow the homeowner to apply for this. But it is all about money!! They really don't care if its up to code because if they did then they wouldnt care who applied and payeed for it, but they want the contractor to do it so if they do something wrong they can fine them instead of just pointing it out and allowing them to do it right.
Is there a such thing as a PQ-15 valve? No…but how do we know? And oh, by the way, there are only two types of line-sets: 3/4 inch, and 7/8 inch. All modern equipment runs on a 7/8 inch line-set, so the only time they’ll have to change something is if you have antiquated 3/4 inch line-set from the 60’s or 70’s. I’m digressing though…the point is that they can easily prey on uninformed consumers…like you, baby bird! Don’t worry though…you’ll be flying by the end of this article.
If you’re anything like most of our readers, you’ve spent hours online researching HVAC information in preparation for replacing your old heater or air conditioner. I’m the same way; it’s a big investment! You may want to consider saving yourself some time and money by getting an HVAC-Facts Report from this online HVAC installation cost calculator. Take a look:
This is where i found where the major problem was for the dust problem in my home. I took down the sheet metal that was 16" wide down by taking the screws out that keep it attached and when i took it down i, could not beleive the amountbof dust that was up there, inhad to put on breathing nasks to actually scoop out all the cust with my hads and then i used my shop vac then bleached everything, i would say that i filled up a 5 gallon maybe more not counting all the dust that was attached to the side of the beams that was all wood , because the contractor did not actually build a 16" wide return all out of metal , butvinstead used the sheet metal plate as a short cut to make a suare box using my beams in my basement to make a suare box. I was told contractors do that often and i feel that should be outlawed because it caused my sinus and allery problems,nwhich almost caused me to die. so everyone should make sure their ductwork was made properly. Yes seal it . Cover all openings. So it was not the contractors fault that my vents still had dust, in them, he was afraid tomgetvon top of my pool table to try to get iside the short cut ductwork with the 16" wide sheet metal. To everyone, make sure you clean your vent system. And make sure you could see it visually like i did , neither i or the contractor had no clue the problem was right above my pool table because of the make shift ductwork. The contactor shoul have made a squrae duct like the rest instead of using my beams as a short cut. That could be whyba lot of people start to have major allergy problems and maybe even ashma.so coverall holes to prevent dust to be taken in and all bugs etc. then make sure you clean your ductwork as you see reasonable, they say every 5 years , but i say evry 2 to 3 years, but you can do it yoursely.. You need a good air hose and suction vacum like a shop vac, do a little research. I invented something a while back like 18 to 20 years ago , and now it is on the market to help homeowners such as ourselves with this dust problem. I cannont say anymore because i have to make sure that it was not my research and idea that solved my problem and for all the others that are using what i invented ..there was nothing on the patent search that i hired an invention company to do, back then. Once yor vents are cleaned properly younwill be very happybif you are an allery sufferer. Stop the children for throwing things into the ductwork and sweeping things into the ductwork, keeping your vent system is clean once youbclean it right the first time, just maintain it , you dhould keepmthe hvac system clean such as coils etc it truly helps,people vome into my condo and they cannont beleive how cold it igets and how my system works so well. it is because i have my whole duct system sealed outsid with the duct sealant and my coils i vleaned my self and take the time that the furnase fan is cleaned because that could have a lot of major dust attached to it, mine had a lot of caked on dust it was like hard dirt. Yxounwill save on allergy bills nasal sprays, i wish I could say more because incould say something to really keep your whole duct system clean for years once you do a first good cleaning of intake and return vents. until i email one of the major companies to see where they got my idea from. Intrulybhope it was not from the invention company i hired years ago who did the patent search for my idea. I becam
A Full Installation is the most common type of HVAC installation for a reputable contractor. The ductwork adds two days of labor and about $2,000 to $3,000 to the price, but realize that this is a very important part of your HVAC system. Although it might sound like a good idea to reduce HVAC installation cost and get a quick change-out, realize that there is dirt and debris collecting in your ducts, and the ducts themselves develop holes and full breaks over the lifetime of your unit, all of which may be hidden from sight by insulation. Remember, many contractors will push a quick change-out on you because it is easy and good money for them – you need to be involved and ask questions.
Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. Many companies are marketing products and services intended to improve the quality of your indoor air. You have probably seen an advertisement, received a coupon in the mail, or been approached directly by a company offering to clean your air ducts as a means of improving your home's indoor air quality. These services typically — but not always — range in cost from $450 to $1,000 per heating and cooling system, depending on:
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls.
One of the best ways to know if your ducts or vents need to be cleaned is to just check them. Your eyes will be able to check for indications of mold, dust or pollen buildup. You might also be able to smell the presence of mold, which would be a clear indicator. Ductwork will have some buildup of dust, since the return registrars pull air back in. However, this doesn't mean your ducts have too much debris, and you can easily clean them with a duster or vacuum.
My point is that the brand of equipment you choose is going to affect your HVAC installation cost greatly. People often call us for an air conditioning installation job and say, “I would like to install Carrier equipment.” Now, if you are a future client of ours, I’ll have to warn you – I can be a bit of a smart-ass. Why can’t work be fun? Besides…I was in the Navy for 11 years, what do you expect.
Lennox, on the other hand, is probably the most expensive unit out there and I can’t stand them. In our (humble?) experience, they have a horrible logistics chain, making repair parts difficult to come by (sometimes taking weeks), poor customer service, and the parts cost three times as much. That’s not what this article is about, so read more in: Carrier vs. Lennox Furnace Review.
A house breathes just like you an I.For example every time your clothes dryer comes on it automatically creates a negative pressure inside the home.So if air goes out of the living area it has to be replaced.....now look above the ceiling fan ....you see the cover...underneath that is a hole straight to your attic....Now the stuff on your ceiling fan you call dust...call it insulation,rat fecies or anything else that is in your attic that could be pulled in your due to a negative pressure.
I'd have to disagree with all of your statements. Not only are they derived from no experience in the field, you are missing keys facts. Ducts even if air tight will get dirty. If they are not getting dirty, it means they are not working. Your returns side of the duct work is always under negative pressure when the system is operational.Therefore it is always drawing air in. Seeing how dust is made up mostly from dead skin humans shed daily. Around 1.6 Pounds of skin a year per human. Living in your home anything that is air born will be drawn back towards the cold air returns. That is what they are designed for, to draw stale air back to the system to be filtered and sent back through the house.Homes with carpet will actually have cleaner duct work than home with all tile or hardwood. This is because carpets hold onto dust particles and you vacuum them up. Whereas on hardwood or tile, dust can run freely back to the returns. Even if a duct system was sealed 100%, which is next to impossible to achieve 100% would still need to be cleaned. The cleaning may only have to be every 7-10 years for example. Most homes require every 5-7 years. And that's if it was done properly the first time. If you constantly hire people that have no or minimal knowledge of duct cleaning, You home would require cleaning more often. Every 2 years. That's a trade secret, The longer they recommend before the next cleaning, the odds are they did it right. That's not to say there aren't people that lie, because there are. Just have your duct cleaner take pictures before and after cleaning. Not just an outside view. Get in there, picture entire joist liners, Whole main runs and even long round pipes. Also it helps to have a company that guarantees their work. If it's not done right, they will come back and do it until it is. Most companies that do this make sure it is right the first time. Your not getting paid to do the job twice.
