How Can Ductless Air Conditioning Benefit My Home?

Friday, May 30th, 2014

Ductless air conditioning in Stamford a great option for some of our customers. Used frequently in commercial spaces like restaurants, ductless air conditioning has moved into the residential market, giving homeowners another option when considering the installation of air conditioning to their property. With over 35 years in air conditioning installation, repair and maintenance, Celco Heating and Air Conditioning knows that when choosing an air conditioner for your home, it is always best to know what options you have. Below, we’ll discuss some of the benefits of ductless air conditioning.

No Ducts Needed

There are a lot of beautiful, older homes in the Stamford area. Many older homes were not built with air ducts, as heat delivery was conducted through radiators or baseboard heating. Ductless air conditioners allow for whole-home air conditioning without having to install air ducts or utilize multiple window units.

Custom Cooling

The blowers for a ductless air conditioner operate individually, giving you complete control over the temperature of the space in which the blower is installed. How? Each blower has its own programmable thermostat, enabling you to run a blower at a specific temperature during specific times.

Better Energy Efficiency

Not only do ductless systems have SEER numbers within current federal guidelines, the ability to customize your cooling, as discussed above, helps with energy efficiency. Why? With individual blowers, you don’t need to worry about cooling a space that isn’t occupied. This is known as zone control, and it can contribute a lot to achieving lower monthly utility bills.

Less Space Requirement

Ductwork needs a great deal of space for installation; in contrast, the blowers for a ductless air conditioning system are a little over a half-foot long and about 3 inches deep – a much smaller size. As such, they fit easily into a variety spaces, including over door frames.

Cleaner Installment

With no ductwork to contend with, the installation of a ductless system can be quite clean in comparison to a ducted system. All that is required with a ductless air conditioner is that the blower be connected to the outdoor unit. This happens through a small hole – about 3 inches in diameter – being drilled into an exterior wall.

Is a Ductless Air Conditioning System For You?

A lot of considerations should go into any air conditioning purchase.

3 Advantages of Modular Commercial Air Conditioning

Friday, May 23rd, 2014

Keeping your business cooled down during a long summer is vital for protecting your revenue. An overheated building means unproductive employees and unhappy customers and clients.

Searching for the right commercial air conditioning in Norwalk, CT may seem intimidating, but you only need to find the right professional commercial HVAC installer to handle the work (contractors who only do residential installations are not suitable) and most of your worries will vanish.

Call Celco Heating and Air Conditioning today and talk to our commercial air conditioning specialists about how we can cool down your business.

One of the options you have is modular air conditioning, and we’ll explore this possibility here.

What is modular air conditioning

Modular ACs are commercial units that come in separate modules able to integrate in a variety of ways and sizes. The purpose of these systems is to shift away from the traditional installation style of putting in a system from the ground-up at a business. Instead, the modules are created off-site, and the installers select a configuration of the different modules to fit with a business’ size and layout, all without sacrificing customization.

What are the advantages of modular ACs?

  1. Fast, phased installation: Putting in a modular air conditioning system does not have to be done all at once, causing a shutdown of your business while the work is done. You can easily tailor the installation schedule around your work, and not the other way around. Because the modules are smaller than a traditional central system and already completed off site, they can be quickly installed.
  2. Easily increase the cooling load: Modular systems come in units of 12-ton, 15-ton, 20-ton, and 25-ton modules to fit your cooling requirements. These can be put together into units up to 50 tons of cooling power. You don’t have to replace a smaller system for a newer one if your business grows and needs additional comfort levels.
  3. Efficiency: The individual modules of modular ACs are extremely durable, capable of dealing with weather extremes. Because of their rooftop location, they are easy for repair technicians to access out of the way of your workspace.

Although modular commercial air conditioning for a Norwalk, CT business may sound like the ideal answer for your comfort, it isn’t perfect for every company. You will need to consult with commercial HVAC experts; they will survey your workspace, make important heat load calculations, and recommend which systems can provide you with the comfort you and your employees/customers need.

Celco Heating and Air Conditioning takes pride in the service we offer for commercial heating and cooling. Since 1976, we’ve kept businesses in Fairfield and New Haven counties shielded from the weather outside.

What Are the Principles Behind Geothermal Cooling?

Friday, May 16th, 2014

Cooling a home down using the power of a geothermal heat pump is one of the most reliable and energy-saving methods of air conditioning. The U.S. Department of Energy estimates that geothermal heat pumps work three to four times more efficiently than standard air-source heat pumps. They also have extraordinary longevity: the indoor heat pump components can last 20 years, and the in-ground coils can last more than 50. Geothermal power also produces few emissions, making it a good idea for the environment as well.

But how does geothermal power cool down a home? We’ll explain the surprisingly simple way that a geothermal heat pump delivers you cooling as powerful as any standard air conditioner.

If you’re eager to get started with geothermal cooling in New Haven, CT, contact our technicians at Celco Heating and Air Conditioning. We have helped customers year-round since 1976.

How geothermal cooling operates

The basic principle behind geothermal cooling is heat exchange, which is also the principle behind air conditioners and air-source heat pumps. Geothermal home comfort systems are types of heat pumps: they move heat from one location and deposit it in another. However, the standard heat pump uses the air as the medium for its heat exchange. During hot weather, the heat pump removes heat from the indoor air and puts it in the outdoor air, lowering the indoor temperature. During cold weather, it reverses the process.

A geothermal heat pump, however, is a ground-source heat pump: it uses the earth’s warmth for half of the heat exchange process. During the summer, the indoor unit absorbs heat through evaporation, just like an air conditioner does. But it moves the heat through water-filled coils down into the ground and deposits it there. The ground coils are buried 10 feet or deeper beneath the surface, where the temperature stabilizes around 55°F. The stable temperature is how geothermal heat pumps achieve their high efficiency; they do not have to worry about temperature fluctuations in the air that can make it harder to carry out heat exchange. This is especially important during the winter, when the heat pump switches from cooling mode to heating mode; the low temperatures of a Connecticut winter have no effect on a ground-source heat pump, because the underground temperature remains the same.

Professional geothermal installation

The work involved required to install a geothermal heat pump is intensive and time-consuming. You should only entrust it to expert installers who will make the work go as smoothly and quickly as possible. For quality installation for geothermal cooling in New Haven, CT, contact Celco Heating and Air Conditioning today.

3 Common Air Conditioning Repairs

Friday, May 9th, 2014

Summer is on the way, and with it comes the possibility of air conditioning repairs. We all want our air conditioners to respond without difficulty and with a little care and maintenance, you can reduce the risk of a breakdown considerably. But sooner or later, every appliance suffers problems, and with most air conditioners undergoing daily use, chances are you’re going to encounter trouble somewhere along the line. Air conditioning repair in Westport CT can usually address most problems, but the more you understand about your air conditioner, the more quickly you can spot signs of trouble.

Common Air Conditioning Repairs to be Mindful of

  • Low refrigerant. Your air conditioner needs a specific amount of refrigerant to function as it should. (The exact amount and type of refrigerant depends on the model of air conditioner.) When a leak springs up in the system, it reduces your air conditioner’s ability to cool the air. Ice will form on the evaporator coils and the unit itself will have to work harder to do the same job. Cleaning the ice off won’t help. You need to have a professional seal the leak and recharge the refrigerant to its proper levels.
  • Faulty fan motor. The fan motor can suffer from any number of problems, from an overload to an electrical problem resulting from faulty connections. When it runs into trouble, the air won’t flow as smoothly, and may not even flow at all. Check the reset button on the motor if you suspect problems. If hitting it doesn’t correct the issue, you should call in a professional.
  • Dirty filters and clogs. Filters can create clogs in the system, as can build-up from dust, dirt and other detritus. In the short term, they can lower the quality of the air in your home. In the long term, they can impede the flow of air into your home and cost you unnecessary energy whenever you run your system.

Air conditioning repairs come in all shapes and sizes, but if you know some of the most common, you’re one step ahead of the game. The next step is to call the experts at Celco Heating and Air Conditioning.

We handle all kinds of air conditioning repair in Westport CT, and we won’t rest until you’re completely satisfied. Give us a call today and let us show you what we can do!

Problems Caused by Damaged Ductwork

Friday, May 2nd, 2014

The ductwork that forms the channels of your ventilation system must maintain a constant seal. This way, the air that travels through it will not drop in pressure and affect the airflow from the vents. However, should the seal break, air pressure is only one of the problems that can occur.

You need to have professionals repair damaged ductwork—this isn’t a job for commercial duct tape! If you feel air that’s the wrong temperature coming from the vents, detect musty odors in the air, or notice a build-up of dirt in your home, you may have leaky ducts. Call the team at Celco Heating and Air Conditioning to handle the repairs for your ductwork in Milford, CT. We’ve kept ventilation systems in prime shape since 1976.

What can happen because of damaged ducts?

  • A drop in heating/cooling power: Because a leak in a duct will lower the air pressure inside, the airflow from the vents into rooms will plunge. The power to heat and cool will drop with it. During heating season, heat will also escape from the duct breaks, and during cooling season, heat will enter the breaks.
  • Rise in utility bills: Losing air pressure, as well as an increase of dust and dirt entering the ductwork, will put additional stress on the air conditioner/heater. This will make it strain to work, and will turn the system inefficient. You can expect a rise in your utility bills because the HVAC system has additional stress. (There’s also a higher chance it will incur repairs.)
  • Lowered indoor air quality: Any dust or debris that enters into ductwork can also then enter the air in your house. A break in a duct will make the situation worse. Since these leaks will usually open onto closed and dusty spots in a house (crawl spaces, between walls), they will draw in large amounts of contamination. They can also permit moisture in and cause bacterial growth, like mold. This will have a negative effect on your air quality.

Hire professionals for your duct sealing

For duct repairs, trust to experienced duct sealers to take care of the problem. They will track down all the leaks and use mastic sealant or metal tape to patch up the leaks and restore your ventilation to leak-free state.
