Alberto said they were busy but could either install on the upcoming Saturday.  We were going to be out of town and said unfortunately that day did not work.  He then proposed the upcoming Tuesday as a possible solution, but just had to confirm with another appointment.  I said great.  I will review the estimate and call your office to confirm I want to move forward with the install.
I called a company name “GREEN RHVAC” with their $29.00 one system air duck cleaning. When the guy came with a truck I asked him to tell me how much he will charge and he said that if he gave me price and I didn’t want the service then he would charge me $89 or he would tell me how much he charge me after he finished the work. I immoderately sense that I made mistake to call him to my house. To cut my lost I asked him to give me the price and it was $1600 for two systems house. I paid $100 to him for my lesson to learn and search online to find this site is very helpfully and I should do it before to call anyone for air duck cleaning.

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.

PickHVAC Tips: Electricity resistance heat is the most expensive heating type. You don’t want one of these unless you’re heating less than 30 days per year. The upfront cost of an electric furnace is much lower than the cost of a gas furnace. However, operating costs are two to three times higher. If winters are cold where you live, you’ll waste your upfront cost savings in just a few years of high electric bills.

Contact/Relay -- Relays are electronically controlled switches that activate the various components of your HVAC system. They manage everything from the power going to the motor to automatic dampers, humidifiers, etc. Most of them are controlled by the thermostat. The most common failure for a relay is being stuck in the "open" position. Separated from its assigned contact point, it fails to complete the connection and send the message to whatever it was supposed to operate. This failure usually occurs from use over time. Each time a relay connects and sends its signal, the electrical arcing from point to point eventually causes wear and tear.
I was told that 15 out vents would be cleaned and one main vent. the guy came over and gave me an estimate of $500. I had acquired a groupon for $49. the guy said just doing the out vents and one main vent would accomplish nothing. Now I am in dispute with the groupon people for a refund which they won’t give and have to go ahead and waste the money and let them do it. Is their doing the 15 outvents and one main one going to accomplish anything?

Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems.
One problem occurred on Monday.  When we called at 2:30 in the afternoon to check on status, we were told that "the tech is on the phone with the parts supplier now".  It seems more likely that they had forgotten about us and our call woke them up.  But even if true, why the heck did they wait until 2:30 to order the part?  Maybe if they had ordered it in the morning they could have had it the same day.  So I'm taking off one star for that.
I noticed a lot of negative feedback, though unfortunately there are many dishonest companies out there. I currently work with a company that cleans duct work and we DO NOT use any scare tactics or up sell services or equipment. Once every 10years of course there are exceptions. We clean supply, returns, air handler, housing, motor, and fan. Though be discerning when qualifying anyone to work in your home. I would ask for REAL REFERENCES to contact.
If you think duct cleaning might be a good idea for your home, but you are not sure, talk to a professional. The company that services your heating and cooling system may be a good source of advice. You may also want to contact professional duct cleaning service providers and ask them about the services they provide. Remember, they are trying to sell you a service, so ask questions and insist on complete and knowledgeable answers.
Good article, but it fails to point out that leaky return-side ducts could be drawing dust and allergens into the duct system from the enclosed spaces in which they run, e.g. between walls, below floors, attic. So duct cleaning may only be a temporary solution. The homeowner can get a home energy audit -- free in many states -- to determine if they have significant duct leakage. An Aeroseal dealer may be able to effectively seal up the duct system without needing to tear into walls etc to get to the ducts.
Furnace cleaners are mostly young men, I know this, I have been one for 15 years or so……so heres the truth, if there are any allergies, children, older people with health issues, we are GOING to make money. do not tell the company you have hired about any health complication. they are salesmen. and they don’t care about you. or your money. make sure they do a good job, then kick them out. you don’t need all the bells and whistles they wanna sell you. any idiot can clean duct work, like I said, I am one of them. I am very good at it, but I don’t have the back bone to sell a widowed old lady a humidifier that she doesn’t need for 500 bucks, overall, if you think you need this service done, which you probably don’t, get it done, do not spend anything over 300$ and do not do it again for at least ten years.
Hi guys if your not convinced yet that duct cleaning is a waste of time. I’m a HVAC business owner install heaters and air conditioners. Simple facts if you have an old system get a new return air fitted with a filter it will catch all the dirt and dust. If you still have as many do black flecks and stuff coming through it is the lining inside your ducting that has perished. So somewhere you have a hole or very old ducting. If you had rats etc its a hole somewhere. To clean, stick your vacuum in the outlet and push the hose as far as it will go this gets 99% of toys and coins fur and alike. Think about it if the object is not heavy it will come out the duct when unit is on. Service the heaters or air con units but not the ducting. I would go further to say that duct cleaning actually damages the ducting in my opinion.

Yes, ducts can look terribly dusty. However, that dust will not become aerosolized during the normal operation of your furnace. There is an easy way to test this. Rent a particle counter and test the air flowing out of your registers before and after cleaning. You will not see any improvement in the air quality or any reduction in the airborne dust level. Think of it this way. Duct cleaning companies tell you that you need to clean your ducts when you can see a layer of dust in your ducts. Yet that very layer of dust is proof that duct cleaning is unnecessary, because that dust proves that the air movement in your furnace is not fast enough to re-aerosolize the dust.
You've probably noticed many appliances boasting an Energy Star Certification. What this means is that manufacturer voluntarily built the product to help reduce greenhouse gases and meet non-regulatory guidelines offered by the Environmental Protection Agency. To earn an Energy Star rating, a product or system must be tested by a third party that has been recognized by the EPA for meeting their testing qualifications.
Pro Tips: Before you buy one of the learning thermostats available, you should beware of their shortcomings. First, many require a c-wire to work properly. A common problem is that the old thermostat might not use a c-wire, and this makes it confusing when swapping wires to the new thermostat. Secondly, if you change your thermostat setting often, you might become frustrated with a nest thermostat or other learning thermostat. It will be constantly trying to learn patterns in your random setting changes, and will therefore change your home’s temperature when you don’t want it to. If you have a fairly consistent schedule or don’t mind overriding the unit either manually or via the app on your way home or when leaving, then you won’t experience this issue.
Asking how much an HVAC installation costs is kind of like asking, “how much does a new car cost?”  Well, are you buying a Porsche or a Honda? Is it a 911 or just a Boxster, and are you going to get the leather seats? Likewise, are you going to get a Carrier or a Goodman air conditioner? Does the ductwork need to be replaced? These are all questions that will affect your HVAC installation cost, so let’s take a closer look.

Be careful of dishonest HVAC contractors. There’s no magical formula to see if an HVAC contractor is scamming you, unfortunately, but remember that they typically do this in one of two ways: first, they are charging grossly low prices (far below everyone else), or second, they aren’t including what everyone else is. In the first situation, they will charge you change fees, other hidden fees, or they stole the equipment and are passing themselves off as legitimate contractors (very common in California these days). In the second situation, they are charging you a very fair price, but aren’t including what the other contractors are (i.e. charging $10,500 for the installation which is fair, but not including the ductwork which is a scam unless there is some other, complex stuff going on there).
in response to this reply " should your ducts be cleaned", i have to politely correct the person who answered this. you are not using common sense. first, most of the country uses metal duct work, so for you to say what you did, is wrong. second, the duct system in a house is a circulatory system. that means it draws air into the furnace, it gets filtered, and then it is blown out into the house to heat or cool. So, obviously that air is being brought into the house from somewhere right? Yes, its coming from the outside where there are many allergens and dust particles . For you to says that about whether a duct system is sealed or not, makes no difference. The air is coming from somewhere right? It has to originate from somewhere right? Just look on top of your cieling fan. If there is a bunch of dust up there, then there is obviously a bunch in your ducts. And the duct air is being circulated every day, and every hour through your house. Its simple, dust collects everywhere in your house. Imagine if you never dusted your shelves, or tv? There would be a ton of dust after a while. Well, now think about the air in the duct system. Of course theres gonna be a ton of dust in there. For you to say that it is not benififcial to clean the ducts, is plain ignorant. 90% of the air we breathe is in our household. Wouldnt you want that air to be as dust and allergen free? I could go on for hours about the benifits of duct cleaning, but i just wanted to make a quick point that the person whose says it is not benificial to clean them, is not using common sense. Not to mention, giving the people who clean ducts for a living, a bad name. Use your head .
This is to Blueberry who.wrote.about home rental dust problems on 12/ 06/2016. If you’ve been there 13 years.your landlord has made enough money to have those problems repaired.I would call your city property standards dept. And let them know what.conditions you are having to live.There is no excuse for living in those conditions when most problems like that are easy fixes.Especially if your kids are getting sick. Tell your landlord your.calling City Health Inspector if he doesn’t fix.the problems.
Knowing what you should be paying for your HVAC equipment and installation is essential to getting a fair deal. Most HVAC prices aren’t advertised. Contractor strategy is to get a salesperson into your home to sell you on a package of equipment, accessories and installation. This makes comparing systems difficult, and some sales pressure might be applied.

Bigger is not necessarily better when it comes to HVAC systems, and smaller isn't always more efficient. If you have too small of a system, your system will be running constantly as it tries to keep up with the temperature. If you have too large of a system, it won't run long enough to keep up with the humidity. In order to handle both temperature and humidity efficiently, an HVAC system should run for around 30 minutes at a time. If your system is staying on too long or shutting off after only around 10 minutes, you are not getting efficient performance.
I own and live in a mobile home and was told to install a mobile home air condition well I did not want one because the ones for moblie homes are to small,so I install a home air-condidtion and its good for heating and cooling the only thing I do is change is the filter every month or two,What I want to know is how does dirt and dust comes from????
Just had my air ducts cleaned. They used a high pressure air hose in all the heat ducts and cold air returns. He showed me the stuff that came out, the reason for the duct cleaning was the fact that I had a problem. With rodents. There was quite a few mummified rats and mice, and he said I wouldn’t have to have them done again unless I incur another problem or have renovations done. Cost me 345.00 for a 2 storey large old home. Not a bad price as I had them done when I moved in 28 years ago and it cost me 500.00. Lots of dog hair, toys, balls and assorted goodies came out as well. Took them 2 hours. I did have sanitizer put in the ducts because of the dead rodents.
I live in a 1950's ranch house in the South. The prior owners were smokers. Based on recommendations from one of the local conservation organizations, I decided to have a home energy audit done. As part of their findings, they recommended additional insulation in the attic and duct cleaning and sealing. This turned out to be a very problematic process. In terms of the ducts, it was necessary to remove the metal grates. However, these grates had been painted over many times and shoe molding covered the bottom of the grates. The vendor was not able to remove the grates without damaging them in the process. Because these grates dated back to the 1950's, it was difficult to find appropriate replacements. The ones I finally discovered were correct except they were 1/4" wider. This meant that the shoe molding had to be carved out. The duct cleaner could not provide any assistance with this problem. It took me a month of long evenings replacing the vent covers myself, carefully chiseling out the shoe molding and repainting. In terms of the extra installation in the attic, the same vendor used blow in insulation. Unfortunately, they did not recognize that the 13 floodlights whose mounting extended into the attic were not designed to be buried under insulation. The problem manifested itself in terms of expensive flood light bulbs failing continually. So, I had to have all of the light housings replaced. Yet another unexpected expense. Despite the expense, pain and suffering, I cannot report any improvement in my heating costs or the "quality" of the air. To be fair, I do not have any allergies and did not undertake this for air quality improvements but rather heating efficiency improvements.

SEER is useful for comparing one model to another much in the same way that a car's calculate MPG is useful. It's not an accurate prediction of exactly how efficient the system is, but it can tell you which one is more efficient. Also, since SEER is based on a "cooling season", what region you live in will determine how long or short your cooling season is.
If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.
