Is That Normal? Sound Advice About Air Conditioner Noise

Sometimes our cars, appliances, and even air conditioners make the strangest noises, but how do you know if they’re normal or if something might be wrong? It’s not always as easy as hitting the ‘restart’ button on your computer, so it’s important to know when you should call a professional or contractor to check it out. The following are some tips about what sounds are normal and what indicates professional problem when it comes to your air conditioning unit.

Outdoor unit noise is normal upon start-up and shut down. The outdoor unit is where most of the mechanical operations in your system take place and depending on the type of equipment, it can be noisy and somewhat varied when it starts up and/or shuts down. Typically, most air conditioners make noise when they first cycle on, which can be caused by the buildup of pressure in the refrigerant lines or from bearings, fans or other moving pieces starting up. The same is true when the unit cycles off, or comes to a stop, as the pressures need to equalize. Sometimes this causes a unique noise that sounds like air escaping, a click or rattle.
◾Tip: If the start-up and shut down sounds are the same from cycle to cycle and not too loud, it’s probably normal and not worth calling a contractor.

Outdoor unit running noise after start-up can also vary among different types of equipment. Once the outdoor unit starts up, it should reach a consistent sound where you hear the fan blowing and the other mechanical parts humming along. Sometimes you might hear a cycling sound over the period of a few seconds where the unit changes the pitch of its normal running sound and might get louder or quieter in “waves.” If it gets increasingly louder as the system is running, then it might require a contractor to see whether it is out of balance or requires further inspection. If you hear a loud, intermittent mechanical “scraping” or “banging” noise, this is not normal and you should shut your system down and call a contractor to inspect it as soon as possible.
◾Tip: Significant changes in pitch or ‘banging’ noises indicate you should call a contractor.

Indoor unit sound is usually the sound of the fan moving air through your system. It is most noticeable when the system turns on and off. If you have a high efficiency system (16 SEER and over) you could hear two distinct sounds as your system moves from high to low cooling speed. The high speed sound can be noticeable, but the low might be so quiet you can barely hear it.
◾Tip: Air moving through your system should sound smooth and consistent once it is running.

In general, sound is a subjective attribute and the above descriptions are provided as a guideline for noises that could potentially signal a costly problem. In addition, we have recorded some typical compressor sounds you might hear during a normal start up, run and shut down cycle as examples

Duct System Design: Get it Right From the Get-Go or Try, Try Again

The efficiency of the cooling equipment in your northeast Florida home is directly tied to your duct system design.

If the ducting isn’t properly planned, the distribution of your air affects your comfort, the quality of your indoor air and your energy costs.

New Home Duct System Design

Years ago, the ducting system was installed almost as an afterthought. Poorly distributed ducts exist in millions of older homes and are costing homeowners with needlessly higher energy bills. In recent years, however, energy-conscious architects and home builders have become aware of how important duct design is for new homes. Basic supply duct configurations get more attention in early planning stages than they did previously, maximizing the efficiency of present-day heating and cooling systems.

Problems With Poor Airflow

A poorly planned duct system design can result in airflow problems that a homeowner may never have a clue about. Depending on the age of your home, having a professional evaluation and altering your ducts could potentially result in significant savings in annual energy costs. Here’s a list of some of the common problems homeowners face:

•Too few supply or return vents in rooms
•Long runs of incorrectly sized ducts to distant rooms
•Sharp turns or junctions where airflow is slowed
•Exposed ducts that aren’t sealed inside conditioned spaces
•Bad seals at delivery and return vents

Ideally, all ducts should be contained in conditioned spaces. If this isn’t possible, they should be well insulated. Ducts should be configured so that there are easily graduated turns which don’t interfere with the velocity of the air. If the air speed slows, poor distribution throughout the home can result.

These are all problems resulting in higher costs and lower comfort.

If you’d like more information about how your silent and hidden ducts should work, contact the experts at Ation Heating and Air Conditioning. We’re happy to help educate you about the value of good duct system design, as well as answer any other home comfort questions you may have.

Website Seeks Illegal R-22 Information

A Website has been set up to allow browsers to report what they consider illegally sold HCFC-22. “If someone offers you an incredible deal on R-22, it likely is too good to be true,” is part of the statement on the home page of www.klexserve.com/catch22 for its Catch-22 Compliance Line.

The statement goes on to say, “Don’t help perpetrate a crime and put yourself in jeopardy at the same time.” Browsers are directed to a link asking for the submitter’s name, address, and phone number - although the submitter does not have to provide that info - and then asks for details about the possible illegal refrigerant.

“Buying and selling R-22 is a regulated activity,” the site said. “Only those authorized under the Environmental Protection Agency’s Clean Air Act can do so. Companies with authorized allowances given by the EPA want to make sure that the R-22 market is a level playing field for all participants. Buying and selling R-22 is a regulated activity, and only those authorized under the Environmental Protection Agency’s Clean Air Act can do so.”

The site asks for details on the refrigerant in question as well as where and when it was purchased.

At the site, Klexserve is described as “the legal process outsourcing entity of the Kochhar Group, a leading and pre-eminent Indian group specialized in providing diversified services of global and international standards to multinational corporations and their Indian subsidiaries, including several Fortune 500 companies based out of North America, Europe, Canada and Japan.” The site does not make clear whom Kochhar is outsourcing for in this case, although the refrigerant manufacturer Honeywell issued a press release on Feb. 18 saying it “has provided financial support for the Website.” Other refrigerant manufacturers are doing the same, it has been reported.

In its press release, Honeywell said, “the Website (is) aimed at curtailing unauthorized sale or purchase of R-22. The Website allows users to report suspected sale or purchase of the refrigerant, providing information so that authorities can investigate further.”

DuPont issued a statement on Feb. 19, saying, “DuPont has joined forces with other major industry manufacturers to simplify the reporting of R-22 buying and selling activity that is not in compliance with federal rules and regulations. Those who illegally transact R-22 in the U.S. are subject to seizures of the product, large fines and, as evidenced in the recent smuggling operation in Florida, prison sentences. Protect yourself by knowing your refrigerant source. Report known or suspected cases of illegal R-22 activity.”

The site also has a phone number, (866) 506-6134

Efficiency of Geothermal Attracts Nonresidential Users

Geothermal Technology Offers Long-Term Cost Savings

Some interesting breaking news from The Air Conditioning|Heating|Refrigeration News.



With heating and cooling accounting for 40 to 50 percent of power consumption in nonresidential buildings, it highlights the need to increase energy efficiency in these buildings, and geothermal heating and cooling may hold the key, according to a new analysis from Frost & Sullivan.
“Geothermal heating and cooling is an excellent way to conserve energy while employing the earth as the chief energy transfer base,” said Konkana Khaund, Frost & Sullivan energy and environment industry manager. “Despite its huge initial costs, its higher energy efficiency and long-term cost savings are capturing the attention of environmentally conscious end users.”

Frost & Sullivan noted that the geothermal market is reined back by the high capital required to install the technology.

“Nonresidential users are in a better position to invest the capital and gain strong returns on investments in just a couple of years,” said Anu Cherian, senior industry analyst. “However, most end users are inclined towards ‘short termism’ and do not perceive the long-term benefits of investing in this technology.”

Apart from tight spending from end users, the highly competitive geothermal heating and cooling market is also challenged by price wars. To differentiate, Frost & Sullivan said manufacturers need to educate their potential end users about the lifecycle cost savings that can be accrued by investing in geothermal technologies. Installing such environmentally friendly products will also make building owners eligible for tax rebates and incentives.

Overall, geothermal heating and cooling technology’s benefits are expected to attract customers from across segments. Some of these benefits include long lifecycles, reliability, decrease in energy cost, the ability to comply with energy efficiency requirements, and the positive impact on the environment.
