This is How Cooling Towers Work

Tuesday, February 25th, 2014

You often see cooling towers in commercial and industrial sites, helping to keep components cool and allow the HVAC system to do its job with less stress and strain. Here in Avon, cooling towers are a common site for many commercial HVAC units, and installing one could be a very wise move towards keeping your costs down. But what do cooling towers do for you that you wouldn’t fin in an air conditioning system without one? Here’s a brief rundown of how cooling towers work.

In basic terms, they facilitate a heat exchange with the condenser in the HVAC systems, usually using water to transfer away the excess heat.  It starts with a stream of cold water, which pulls excess heat form the convert and helps cool it down. The now-warm water moves through the cool, cooled by a second flow of cool water which evaporates and helps cool off the hot water. Once the water has been restored to a cooler temperature, it can then return to the compressor to continue cool it as well.

Cooling tower come in multiple types, including crossflow cooling towers (which blow the air horizontally while the water flows vertically) and counterflow cooling towers (which blow the air vertically and use pressurized sprays to hit the air with the water). Both types periodically need to be refilled with water, since the process leads to a lot of evaporation and can dry out the unit if you’re not careful. On the other hand, it helps the existing HVAC system handle the load much more effectively, reducing wear and tear and helping lower your overall energy costs in the bargain.

If you know how cooling towers work, you know that they need care and maintenance just like the rest of the HVAC system. In Avon,  We have the experience and know-how to deal with any problems you might experience and we stand by our work with your complete satisfaction in mind.

Professional Chillers Installation and Repair

Wednesday, February 19th, 2014

Chillers form an important part of a commercial HVAC system. They remove heat from liquid vapor using a compressor, an evaporator, a condenser, and a metering device. The cooled liquid then circulates through a heat exchanger to cool down air for an air conditioner, or to cool down equipment.

The work of the four different components in a chiller mean they are devices that require highly trained and professional work to install and repair them. When you need this level of service for your commercial chillers in North Olmsted, OH, make sure you only work with qualified technicians to help you with your chiller installation and repair.

Contact Westland Heating and Air Conditioning. Homeowners and business owners alike have trusted our work for over 25 years.

Installing and repairing chillers

If you need a new chiller, you can have it integrated into your existing HVAC system, which will require the installers to help you select the chiller model that will match up with your system’s requirements for cooling. You can also choose to have a new chiller installed as part of a full installation of a new HVAC system in North Olmsted.

Repairs for chillers go far beyond those required for any residential HVAC system because they contain numerous subsystems, which means that necessary repairs often combine knowledge of many different types of HVAC systems. Chillers can require electrical work, refrigerant leak sealing, water leak sealing, plumbing fixes, and compressor repairs—all on a larger scale than that for any residential unit. For service on a chiller, you need technicians with specialized training and experience.

You can help avoid expensive repairs for a chiller with routine maintenance checks. We recommend you have professional maintenance done on your system once a year to see if it requires any parts replacements and to have a technician perform adjustments, lubrications, and any necessary minor repairs.

If you need repair for chillers in North Olmsted, OH, look to the commercial HVAC services of Westland Heating and Air Conditioning. We have experience with the complex technology involved to deliver the repairs you need. We also perform full installation for new chillers, and carry an excellent line of products so you’ll get the chiller you need. Our maintenance program will help keep your system up and running.

Who Wrote the First Valentine’s Day Love Poem?

Friday, February 14th, 2014

The celebration of Valentine’s Day is often seen as a modern institution, even if the roots of the holiday go back to Late Antiquity and the figures of St. Valentine of Rome and St. Valentine of Terni. It’s difficult to separate our view of February 14th from the more recent phenomenon of greeting cards, comical cupids, and specialty treats from candy companies.

However, not only are some of these traditions older than we might think (mass-produced Valentine’s Day cards were an enormous success in early 19th-century England), but the earliest Valentine’s Day love poem comes from none other than the first great English author, Geoffrey Chaucer, who wrote in the second half of the 14th-century.

Chaucer’s most famous work is The Canterbury Tales, an enormous collection of linked stories in poetry and prose. But his 700-line poem “Parlement of Foules” has the special distinction of being the first surviving record of a connection between Valentine’s Day and romantic love. Chaucer probably composed the poem in 1381–82. At the time, he was a member of the court of King Richard II, holding an important bureaucratic position in London. The date suggests that Chaucer wrote “Parelment of Foules” to honor the first anniversary of the engagement of the English king to Princess Anne of Bohemia.

The poem follows the dream of the narrator, where he walks through Venus’s temple and discovers a meeting of birds where they all choose their mates. This is where the mention of St. Valentine’s Day appears (English modernized):

For this was on St. Valentine’s Day,

When every bird cometh there to choose his mate.

The poem also contains a familiar Valentine’s image, Cupid with his arrows:

Under a tree, beside a well, I saw

Cupid our lord his arrows forge and file;

And at his feet his bow already lay.

When Chaucer mentions St. Valentine’s Day, is he referring specifically to February 14th? Late winter isn’t a time when birds in England would mate. However, the date for the start of spring—when some birds would have started nesting in England—was on February 23rd in the calendars of the time, certainly close enough for Chaucer to take poetic license and nudge it a bit to match with Valentine’s Day.

Love birds remain a popular symbol of Valentine’s Day even now, and for this we can thank Chaucer. In fact, he may very well have invented the link between love and Valentine’s Day, although we will probably never know for certain.

Whoever started these traditions, all of us here at Westland Heating and Air Conditioning hope you have a pleasant February 14th.

Signs of Problems with Your Boiler

Wednesday, February 5th, 2014

Boiler technology is a very old and reliable form of heating for your home. In Avon Lake, boiler systems see a lot of use in many homes, and if properly maintained can last you for many years. Sooner or later, however, every appliance needs repairs and your boiler is no different. The sooner you can spot a potential difficulty, the faster you can get it addressed and possibly keep a small malfunction from turning into a bigger one at the same time. Her are a few signs of problems with your boiler.

  • Strange noises
    If air gets into the system or mineral build-ups appear in the boiler, you’re apt to hear strange gurgling, rattling or whistling noises.  The sounds can be a nuisance, but more importantly, they signal a significant problem with the boiler’s ability to function.
  • Leaks
    Leaks can appear anywhere in the system. You can spot some of them by puddles of water forming, but some leaks are too small to develop a drip. Instead, check the pressure gauge; if the water pressure is dropping you’ve probably got a leak somewhere.
  • No heat
    The most obvious sign that something is wrong with your boiler is the simple fact that it won’t generate heat. If could be any number of things, from a broken thermocouple to a valve failure to a lack of pressure in the pipes. It might even be a malfunctioning thermostat.
  • System keeps shutting down
    If the boiler shuts off unexpectedly before it’s heated the home the way it should. That can stem from low water pressure caused by a leak, a problem with the pump, or with a broken valve, among other reasons.

If you spot the signs of problems with your boiler – basically anything out of the ordinary – then you need to shut off the system and call in a trained plumber right away. For homeowners in Avon Lake, boiler repair can be conducted by the experts at Westland Heating and Air Conditioning.
