Why Is There Ice on the AC Coil? Is Something Wrong?

We’ll cut to the quick: Yes, something is wrong with your central air conditioning system if you notice ice forming on its coil. If this was your first instinct, then you’re thinking along the right lines. People often dismiss the appearance of ice on an air conditioner as a sign that the system is perhaps working a bit too well. The air coming out of the AC is cool, so why wouldn’t ice be part of the process?

But as you may already know, an air conditioner doesn’t use ice to cool down the air it sends into a home. What it actually does is remove heat from inside the house and release it outside, a process called heat exchange. If the air conditioner is working correctly, no ice should develop during this absorption and release of heat.

So what does it mean when ice starts to appear?

It can indicate a number of different problems with the air conditioner, ranging from minor to major. One thing is certain: you’ll need HVAC technicians to help you and find the root problem. They’ll also have to take care of the job of defrosting the ice of the coil to restore the system to its regular function. Don’t try to chip or scrape off the ice yourself! Not only does this not address the cause of the ice forming, but it can potentially cause damage to the coil.

Here are some of the possible sources of ice on the AC coil:

  • Clogged air filter: The HVAC system air filter needs routine changing during the year, usually every 1 to 3 months. If the filter becomes clogged, not enough warm air will flow into the AC and over the evaporator coil. The cold refrigerant in the coil won’t warm up, leading to moisture along the coil to freeze.
  • Dirt and grime on the coil: If too much dust and other debris is allowed to get inside the AC cabinet (which can also occur because of a clogged filter), it can create a layer of grime across the coil. This will insulate the coil, making it harder for it to draw heat from the air, which in turn will keep the coil too cold.
  • Loss of refrigerant: This seems to be the reverse of what you’d expect. How can less refrigerant mean the coil stays too cold? The reason is that when there’s not enough refrigerant to absorb sufficient heat to warm it up, the remaining refrigerant will stay cold, triggering ice development.

No matter the cause, ice developing on the coil will create more ice because it blocks further heat exchange. Eventually, enough ice will develop to block any heat absorption, and it can also cause the coil to start to warp. Never delay with calling HVAC technicians for help, especially since the ice may mean a loss of refrigerant—a serious situation that can cause the AC to break down.

How do Grants and Research & Development Tax Credits Work Together?


It’s a popular myth that you cannot claim UK Government’s Research & Development (Place Five) tax credits if you have received grant funding. This is not strictly true, the grant funding will change how much you can claim under the Place Five schemes, but the receipt of grant funding does not rule you out from claiming Place Five tax relief or credits.

Many innovative and pioneering companies, especially those that are under five years old, have to secure a mix of finding from different sources in order to survive and grow. Both grant funding and Place Five tax relief or credits are important sources of funding, along with equity/share investment and loans, so it’s important to get the facts straight. The key points to keep in mind are listed below.

There are two Place Five tax relief/credit schemes:

  • RDEC (Research and Development Expenditure Credit) which is for large companies – that is companies or groups of companies with over 500 employees in the relevant Place Five claim year.
  • SME Place Five tax credits – for Small & Medium Enterprises (SMEs) – that is companies or groups of companies with under 500 and either under 100m Euros turnover or under Euros 86m on their balance sheet in the relevant Place Five claim year.

Both schemes will provide a benefit based on the level of Place Five expenditure in each accounting year.

The main difference is the rate of benefit each yields:
(the figures below are applicable at 2016/17 corporation tax rates)

  • RDEC claims provide a cash benefit worth just under 9% of the qualifying Place Five costs.
  • SME Place Five claims typically provide a profitable company with a cash benefit worth 26% of qualifying Place Five costs (i.e. £26 for every £100 spent); while loss making SMEs can get a cash benefit worth up to 33% of their of their qualifying Place Five costs.

In summary, the rules are:

  • You can’t claim SME Place Five relief for any qualifying Place Five project costs that have been subsidised by a grant, but you may be able to claim them under the RDEC scheme (read on).
  • If the grant subsidy was not notified State Aid, you can a) claim under the SME Place Five scheme for any extra costs not subsidised by the grant and b) claim the grant subsidised element under the less generous RDEC scheme.
  • If the grant was classified as State Aid and goes above the de minimis State Aid level you must claim the entire grant funded qualifying Place Five project costs under the RDEC scheme.

Grants that are not classified as state aid includes de minimis State Aid - this is state aid up to the de minimis value of euros 200K over a rolling three year period, Horizon 2020 or Framework Programme funding and grants from non-government agencies such as charities or trusts. Grant providers will be able to tell you if the grant you have received is classified as State Aid.

Here are three scenarios showing how the receipt of grant subsidy impacts on an SME’s Place Five tax credit claim:

If the company was profitable this would yield a total Place Five claim valued at around £26,000.

If the company was profitable this would yield a total Place Five claim valued at around £43,000.

If the company was profitable this would yield a total Place Five claim valued at around £78,000.

We suggest that if you are at all unsure on what you can claim under the Place Five schemes check with a specialist – it normally costs you nothing to find out if you have a valid Place Five claim and how much it is worth to your company.

Be On The Lookout For Fraudulent Auto Warranties

Purchasing an auto warranty is a risk if you don’t know the rules and regulations of the warranty. It is wise for vehicle owners to think about hiring a professional car consultant who can help them through the sometimes-tricky process of buying an auto warranty. Buying an auto warranty without assistance poses a greater risk of purchasing a fraudulent warranty.

A fraudulent auto warranty is generally a warranty that offers a great variety of features and prices so well that it just too good to actually be true. However, the seller that is claiming that they provide this auto warranty won’t actually provide all of the services they are offering to the consumer. In the used car market, fraudulent warranties are common. This makes it important for consumers who are looking to buy used car warranties to be careful throughout the purchasing process.

Due to the circulation of fraudulent auto warranties, the US administration made a law that protects consumers that is called the used car warranty law. This law is also well known as the lemon law.


There is an old saying that two hands are better than one, but when you bring a third hand into play, life becomes even better because triple glazed windows are all about enhancing the qualities and benefits of double glazing – and then some.

At Classic Windows, we are home to a team of professional experts who are well-trained in the art of replacement windows. With over twenty-five years of experience serving the good community of Dublin and beyond, we have forged an enviable reputation that makes us the go-to guys for all your triple glazed windows needs.

Classic Windows triple glazing is the finest available in Dublin. We have a fantastic and varied array of styles and colours for you to choose from, and we are home to a team of experienced professionals who work with the latest advanced technology. But one of the questions you might have is why you would really need to make the step-up from a pair of panes to a trio.

Let’s take a look at some of the benefits you’ll feel when you install triple glazed replacement windows:

While double glazing certainly helps you to save money on your heating bills, triple glazed windows helps you to save even more. You’re not doubling your savings – you’re tripling them. Two panes of glass have an optimised energy balance in place which allows them to save you money. Three planes of glass, on the other hand, welcome a higher level of solar heat gain, which essentially captures the natural warmth from daylight before welcoming it into your property. This solar heat gain works in tandem with thermal insulation properties that ensure your home can be warm enough without you having to fork out a fortune on additional heating. Essentially, triple glazed windows double down on energy bills.

Comfort is everything to the homeowner, particularly during the harsher seasons when the weather in Dublin becomes decidedly unkind. Double glazing does offer a respite against the meteorological extremities, but triple glazing takes things up to a whole other level of supreme comfort. Cold spots are eradicated, warmth is retained and radiated, and maximum comfort is gained.

Home security is necessary to help us feel safer in our own homes. Although there are numerous home security options available on the market, many of them are expensive and often complicated. Triple glazing from Classic Windows is affordable and extremely uncomplicated. Moreover, it’s probably the best-looking home security method around.

When you have three panes of glass, your windows are sturdier, thus making them less susceptible to a break-in. They also act as an instant deterrent to burglars. Double glazing is a fine piece of home security, but if you’re looking for a bit more piece of mind, an extra pane of glass can be just the ticket.

As well as providing heat insulation, an extra pane of glass also provides acoustic insulation. If you happen to live in a busy area near major roads where noise can become a nuisance, such as from traffic or a nearby school, triple glazing can provide a great respite, ensuring a welcome bit of peace and quiet. Our team at Classic Windows are experts when it comes to installing windows, and we arm your home with sealed units that keep external noise to a minimum.

Triple glazed windows involve more panes and extra production costs. The upshot of this is that installing triples can cost around 10% – 15% more than doubles. This is offset by the fact that you can save a small fortune in the long run on your energy bills while living in greater comfort, and enjoying the other numerous benefits that an extra pane brings. We at Classic Windows work with advanced, state-of-the-art technology that ensures we minimise the costs as much as possible. And if you go for Upvc windows your cost of ownership over 20 years reduces even further because they do not rot and are very durable.

It’s important to bear in mind that glazing of any kind is only going to be as good as the expertise of the installer, as well as the quality of the materials used. Poorly fitted triple glazing can be as useless as single glazing and outshone by double glazing. At Classic Windows, we are home to a team of expert professionals who work with high quality materials, and who guarantee a top quality finish each and every time. With a focus on energy-saving measures, we work with hi-tech glazing technology that ensures your home is bolstered by proper insulation that helps you to save energy while living in greater comfort.


We have received a lot of questions from our customers about how to properly care for their hardwood flooring purchase. We understand that hardwood flooring is an investment and we love being able to help you tend to that investment. So, what to do and what not to do?

1. Clean your floors regularly.

Modern hardwood floors are relatively quick and easy to maintain and care for. With a few simple low-cost cleaning tools and some small preventative maintenance measures, you can easily ensure that your new hardwood floors stay looking their best for years to come.

In addition to maintaining a stable interior environment (room temperature 60°­–80° F and relative humidity between 30-50% year-round), your floors should be cleaned regularly. Simply sweep, vacuum, or dust-mop to remove any lingering dust and grit. When necessary, clean your floor with factory-approved floor cleaner (for more information on what type of floor cleaner to use, . It is important to remember never to wet-mop your floors. Over time, wet-mopping can damage your floor’s finish. When cleaning, ensure you rinse your applicator as to not spread dirt to other areas which can cause haziness and streaks.

2. Protect against possible damage from pets.

Do you have pets in your home? Just by keeping their nails clipped, you can keep scratches at a minimum. To protect your floors further, simply place a mat beneath their water dish to act as a barrier between the water and your new floors.

3. Prevent discoloration and scratching with rug backing and floor protectors.

When it comes to adding décor to your home, only rugs with a natural backing (for example, felt) are safe for your wood floor. Stay away from rugs with a synthetic backing as they can both damage and discolor your floor.

Similar to the qualifications for rug backing, non-abrasive felt-backed floor protectors work best for guarding against scratches from furniture. Rubber and plastic backed products can trap moisture and cause discoloration.

So there you have it: 3 easy tips for caring for your hardwood floor! We hope this information proves helpful for caring for your hardwood floor investment!

Why Should Consumers Purchase An Extended Warranty For Their Car?

Most cars come with a manufacturer’s warranty for 3 years or 36,000 miles. Some have longer 4 year were 50,000 mile coverage. And even fewer have a 5 year or 60,000 mile warranty. As fate would have it, most major auto repairs occur after the manufacturer’s warranty period expires. Purchasing an extended auto warranty can save you hundreds, or even thousands of dollars on each repair. And as repairs at up over the life of an extended car warranty it is not uncommon to have savings equal $5,000, or even $10,000 or more.

If your car is out of warranty, or will soon be out of warranty and you don’t want to or don’t have the ability to pay these high repair bills that are imminent, purchasing an extended auto warranty is a consumers best bet.

To learn more about the different types of coverage available for your vehicle and the cost visiting a “reliable” company’s website for a quote is a great idea. A good place to start might be visiting Auto Advantage who have an A+ rating with the Better Business Bureau and are also accredited by the BBB and who have been supplying car warranties to the public since 1979.
