Beating the Heat With Proper Maintenance

Beating the Heat With Proper Maintenance

bright sunWhen summer is upon us, most people get excited and look forward to enjoying the summer sun and beating the heat in a cool, air-conditioned building.  The downside to this pleasure, according to all that we read on behalf of your Heating and Cooling in St Louis near University City, are the summer energy bills.  Most of us all know that the dog days of summer can mean high energy consumption at an unfortunately high price.

In fact, on behalf of your St Louis Heating and Cooling Sales near University City MO, we found a few stats to fill in the gap here and help illuminate the point.  “According to the U.S. Energy Information Administration, space cooling will consume an estimated 1.28 quadrillion British thermal units across the United States in 2017—that’s equivalent to almost 39 million homes’ electricity use in a year. And that energy use adds up.”

We also found, when reading various articles on behalf of your St Louis Heating and Cooling installation near University City, that in residential buildings, space cooling alone makes up 9% of a home’s total energy consumption.  There are also things that can lessen efficiency quite drastically.  “Additionally, typical air conditioning units use fluorocarbon refrigerants as a coolant, which, if leaked, can lessen the efficiency of an AC system and negatively impact the environment.” If you properly maintain your AC unit by contacting professionals, such as your St Louis Heating and Cooling Repair near University City, you will at least improve the chances of having a very efficient system.


Reducing Greenhouse Emissions in Cooling Changes

Reducing Greenhouse Emissions in Cooling Changes

climate changeWe can talk more, if you will, about the movement in the St Louis heating and cooling sales world, about GWP.  “GWP is a basic measure of a compound’s potential to trap heat in the atmosphere, also known as the greenhouse effect, when compared to carbon dioxide. R-410A, a widely used HFC refrigerant, has a GWP that is 2,088 greater than carbon dioxide. R-407C, another popular HFC, has a GWP of 1,774.”  In order to accommodate the atmosphere and do less damage to our ozone, it is important to find chemicals that do the least amount of destruction. According to our St Louis Heating and Cooling near Fenton, and the research and writing we do on their behalf, it is possible to continue to find refrigerants that cool with less and less damage to our atmosphere.

In global news on this subject, from your heating and cooling company in St Louis we found the following:  Later this year policy makers from 197 nations will be meeting in Dubai to finalize an agreement on how to phase down the use of HFCs in developed and developing countries and promote the use of low-GWP alternatives.

A little more than two years ago there was a release in the White House of the President’s Climate Action Plan, which is also very pertinent to this discussion.  In it was a regulatory blueprint for the production of cleaner energy, a more efficient transportation system, the promotion of energy efficient appliances and buildings, and the reduction of non-emissive greenhouse gases. The broad scope, or goal of this plan was to reduce (and still is) to reduce the greenhouse gas emissions, bringing them down to 17% less than they were in 2005, all by the year 2020.  Stay tuned for further details on how the St Louis Heating and Cooling industry near Fenton can play a role in helping this cause.

Recycling HVAC Refrigerant

Recycling HVAC Refrigerant

recycleWhen it comes to the world of HVAC, it is the same as many other industries as of late.  They all want to do their part to help reduce energy usage, both for the consumer and their pocketbooks, along with the environmental benefits that go with it.  “The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published updates to AHRI Guideline Q, Content Recovery and Proper Recycling of Refrigerant Cylinders, which now includes best practices for end-of-life recycling of flammable refrigerant containers.”  So, as mentioned above and discovered in our recent research on behalf of your Earth City HVAC repair near Sunset Hills, there are definitely guidelines to follow when it comes to energy and disposal.

“This guideline and the new additions are a critical part of the industry’s plan for the future of refrigerants,” said Stephen Yurek, AHRI president and CEO. “  There are flammable refrigerants that are being introduced in the world of HVAC as low global warming potential alternatives to the refrigerants that are widely used today.  As this takes place, it becomes a huge topic of discussion, just how these refrigerants are being handled.  They must be recycled and handled properly, not only the substance itself, but the container in which they are being held.

The practices that are being suggested, according to your HVAC Sales and Service near Sunset Hills MO, are totally different one container to the next and depend upon whether or not the refrigerant in question is flammable.  “Recommended practices for recycling containers for flammable refrigerants are different from those for non-flammable refrigerants, in that it involves using a non-sparking pick to prepare the container for recycling. As with all AHRI standards and guidelines, Guideline Q is free to download from AHRI’s website.”

cooling products in MissouriAmerican Services cooling products and services near Fenton is pleased to announce that the latest air conditioning news.

The yearly cooling showcase news has been released recently introducing this years’ latest in air conditioning cooling units available.  The yearly news issue will assist our professional technicians in staying updated on the latest in cooling products and brands available.

“Like last year, this year’s Cooling Showcase is split into two parts — commercial and residential. In this issue, we will focus on the commercial side of the air conditioning industry, while our April 9 issue highlighted new offerings in the residential cooling market. Included in the coverage is feature-specific information about each individual product as submitted by the manufacturers,” said

The commercial Showcase product grid offers technicians many new facts about products such as; different types for refrigerants, efficiency ratings and cooling capacity of several brands, and more.  The manufacturer provides all of the information on cooling products including the product grid.

Some new product information includes; new direct drive fans require no belt maintenance in new products and unit controls and compressors are isolated in a compartment that is separated from the airstream for easier servicing. Other new products include; hinged doors with zinc cast lockable handles which make service access much easier to reach the coils, fans and filters in the unit.

There are some new products for noise reduction as well including; rubber isolation mounts on supply fans which function well to lower vibrations, direct-drive fans wipe out belt noise, and compressors which are compartmentalized prevent sounds from getting into the airstream-just to name a few.

Standard 1 year warranty is available on components as well as workmanship, and a fifteen year warranty is offered on the compressor.

Alternative Heating Sources

Alternative Heating Sources

solor heating in MOAmerican Services Heating and Cooling installation service in Missouri knows that there are many options when it comes to commercial heating systems.

One such option is for heat transfer fluids.  If you are considering solar heating heat transfer systems, be sure to consult the local authority in your area to find out what exactly is required for your geographic area.

Water is one type of substance that is effective as a heat transfer fluid, particularly with its low viscosity property which makes it easy to pump. Drawbacks are its low boiling point and high freezing point, and the fact that water can be corrosive and cause mineral deposits.

Glycol and water mixtures are made up of a 50/50 or 60/40 glycol-to-water ratio. Ethylene and propylene glycol make up the properties of antifreeze.

Hydrocarbon oils have a higher viscosity and lower specific heat than water meaning they need more energy for circulation.  With a low freezing point, these types of oils tend to be relatively less expensive than some others.     The basic categories of hydrocarbon oils are synthetic hydrocarbons, paraffin hydrocarbons, and aromatic refined mineral oils. Synthetic hydrocarbons are relatively nontoxic and require little maintenance. Paraffin hydrocarbons have a wider temperature range between freezing and boiling points than water, but they are toxic and require a double-walled, closed-loop heat exchanger. Aromatic oils are the least viscous of the hydrocarbon oils.

Refrigerants are commonly used in refrigerators, air conditioners, and heat pumps as the primary heat transfer fluid. They generally have a low boiling point and a high heat capacity which enables a small amount of the refrigerant to transfer a large amount of heat very efficiently.

If you currently own a refrigerant-charged solar system that requires maintenance, contact us today at American Services and we will sent out a qualified technician.

Active solar heating uses solar energy to heat transfer fluid or air, which then transfers the solar heat to an interior  storage system for later use. Solar heating systems can be implemented as a supplement to other heating systems such as radiant heating, boilers, heat pumps, or forced-air heating systems.

Active solar heating systems are actually most cost-effective in cold climates that have good solar resources.  Liquid and air systems are good choices for forced air supplemental heating. Note that commercial systems usually come with warranties of 10 years or more and usually last much longer.

Cooing System Pressure Sensors

Cooing System Pressure Sensors

air conditioning cooling systems in MOAmerican Services Cooling System repair and maintenance in Missouri knows that pressure sensors in your HVAC Refrigeration system are paramount to the safe operation of your unit. Proper function of these sensors ensure that your system is operating as it should. If a pressure sensor notices an irregularity, it will notify the computer and proper action can be taken. Every so often a pressure sensor fails and will either give a wrong reading or no reading at all. Times such as these require the replacement of the pressure sensor.

A common refrigerant pressure sensor is the P158 produced by Kavlico. This pressure sensor is compatible with all fluorocarbon refrigerants and refrigerant oils currently in use and in development for refrigeration and HVAC applications. Whether going with the P158 or another model, the pressure sensor must be able to endure high vibration and broad temperature range conditions found in refrigeration systems. Even more so, the pressure sensor must withstand overpressures and pressure pulsations without damage or degradation in performance. Old HVAC refrigeration systems may still have pressure sensors that do not stand up to these new stringent performance regulations. The pressure sensor should be able to operate over a range of -34 degrees to 120 degrees.

When selecting a pressure valve, ensure you are aware of the pressure range that you are attempting to monitor. Pressure sensors can range from 0-100 PSI or 0-750 PSI. If your system operates at high pressure, a low pressure sensor will fail immediately and could cause damage to your system. Furthermore, most sensors have either 1/4 Male or Female pipe threads. Ensure your unit has the same thread pitch prior to installation.
