What Does a Heat Pump Do?

Simply put, the heat pump uses the outside air to heat a home in the winter months while using the same outside air to cool a home during the summer months. The outdoor unit is referred to as a heat pump.  Heat energy is always present, whether in cold or hot temperatures. The heat pump acts like an air conditioner during the summer, removing heat from your home.

A major advantageous aspect of the heat pump is that it doesn’t generate heat, but moves heat, making it more energy efficient. The HVAC system is powered by electricity. What makes the heat pump more energy-efficient is how they operate. The heat pump uses renewable energy in the form of low temperature heat

The major components of the heat pump include:          

 

1.      The outdoor unit – compressor, reverse valve, fan and motor, defrost control, and electrical components

2.      Air Handler – evaporator coil, blower motor, electric heater pack

 

If it seems time to replace your heat pump, contact the professionals at Expert Air to schedule our installation, your maintenance check, or your repair service.  Heat pumps are on a 240-volt circuit, so severe shock or electrocution is possible without a thorough understanding of electricity, so don’t attempt to do the repair yourself.  Most systems today are so technologically advanced that the complexity of repair is more intensive.

What Does a Boiler Really Do?

The boiler, a magnificent tool making cold winter temperatures more enjoyably endurable. The boiler is the key to central heating system bringing warmth to all parts of your space. Imagine a large fire with an endless supply of natural gas via a pipe.  That’s your boiler.  The electric switch that signals the boiler to turn on, has a valve open where gas enters the sealed combustion chamber via mini jets, and an electric ignition system sets them ‘on fire’. The gas jets connect with a heat exchanger to a pipe that carries cold water. Heat exchanger takes energy from gas jets and heats the water to roughly 140 degrees Fahrenheit.

Water travels through each hot-water radiator and then returns to the boiler.  Passing through the radiator, heat is given off and warms the room(s) in turn.  On the way back to the boiler, the water cools significantly, so the boiler must keep going with the fire; it keeps the water temperature high enough to heat your home or office.

 

Good Things to Know About Your Boiler:

1.       Standard efficiency or high-efficiency model

a.       Standard – vented in a metal pipe

b.       High-Efficiency – vented in a PVC pipe

2.       Type of Radiation

a.       Fintube

b.       Baseboard

c.       Cast Iron Radiator

3.       Fuel Source

a.       Gas

b.       Oil

c.       Electricity

4.       Annual maintenance ensures efficient operation, contact Expert Air today to schedule your inspection or to join our maintenance program and gain many perks

What’s the Future for Your Air Conditioning Unit

 

The obvious comfort and relief that comes from your home or business air conditioning unit will forever be significant and a basic requirement for overall well-being.  That may sound a tad extreme but taking it back to psychology, physiological requirements must be met before the psyche can further develop, and from our youngest days to our last days, part of that need is a comfort that your ac unit is built for. 

AC Units are not new though, and the technological advancements for them only continue.  What then does the future hold for your residential or commercial air conditioning system? In some ways, the future is now. We are already experiencing the changes and benefits of home automation and smart technology. Depending on the brand and model.  Smart technology already seems to be integrated into our everyday lives, even for those who aren’t overly tech savvy.  From controlling lighting with a remote or phone application, setting alarms or turning of lights remotely from online, to newer television sets, smart technology has been integrated into these products.

Over the more recent years, the heating and cooling industry has already been integrated by smart technology. You can already control your temperature settings from smartphone applications, which gives you convenience, peace of mind, and improved utility usage. It’s not far fetched to say that in the future voice-activated technology can be used to change your ac unit settings, report the internal status of working components, schedule repairs, and more.

AC units are no longer designed to be bulky, ugly, and disregarded as just a requirement for the home. Today HVAC systems are designed with style, seamlessness, and overall energy impact in mind. Units today are designed to be smaller, blend pleasantly, and be more efficient.

Things to Consider for Chilled Water System

For any commercial company, regardless of size, overhead costs and safety are of the highest concern to be handled efficiently.  Chilled water systems come to mind here because your ac system is a must for comfort, productivity, and safety.  The pros and cons for a chilled water system will be discussed below, but what’s to be remembered is that overall, chilled water systems are cost effective avenues for cool temperatures that are also safe. Safe because having refrigerant piped all over your commercial building, has inherit hazards, and chilled water systems take that hazard out.

 

Advantages

·         Energy Reduction and Lower Utility Bills – Compared to standard air cooled chiller/HVAC system

·         Noise Reduction – Extremely quiet choice, excellent in certain environments.  Water is not as susceptible to duct and vent expansion and contraction.

·         Healthier Option – water is non toxic and non corrosive, unlike your standard cooling systems that use refrigerant and other chemicals for operation

·         Safer Solution – again, no refrigerant piped hazard to be worried about

·         Longevity – Lasts longer than standard air cooled chiller alternative because water chilled is installed indoors and the alternative is outdoors, impacted by the elements.  Also alternative uses chemicals that the water chilled system doesn’t require

 

Disadvantages

·         Higher Upfront Costs – All technology advanced equipment costs more upfront than the standard option. Also, more complex units tend to have higher labor costs due to specialized training.  It can pay for itself over time in a multitude of ways (think advantages)

·         Standard Maintenance Increase – More working parts means more chance of increased inspection, repair, and/or replacement of faulty parts. Water treatments will also be required.

·         Not as Effective in Humid Environments - Higher levels of humidity raise the wet-bulb temperature, which is an indicator of how efficiently water absorbs heat. This equates to higher operating costs.

Whether you are ready for your first water chilled system or need a repair or replacement to your already installed unit, the HVAC technicians at Expert Air are certified, knowledgeable, and professional.  For all your commercial needs, you can rely on Expert Air.
