Is Your A/C Affecting Your Sleep?

According to a recent Economic Times article, your a/c can affect your sleeping more than you think, and perhaps not how you think.  In a recent study by the Journal of Energy and Buildings, participants had significantly greater physical movements, increased heart rates and a higher frequency of wake-ups when the velocity was set at a certain rate.  These results increased even more on participants with lower body strength and / or a greater sensitivity to cold.  In a similar study, researchers at Toyohashi University of Technology in Japan found that the airflow from a standard central a/c system stimulates the human body while sleeping and impacts sleeping conditions even at low airflow levels.  For a further breakdown and more information, please click on the link below to go straight to the article.  A very interesting read to say the least.

Great New Air Conditioning Invention

Engineers at the University of Colorado Boulder have invented a thin film that can actually cool objects without the use of water or electricity!  This invention works to lower the temperature of the surface beneath it through a process known as "passive cooling", meaning that it vents the object's heat via thermal radiation while bouncing off any incoming solar energy that may negate those losses.  This is a pretty astounding development and it could mean huge strides in energy efficiency for both residential and commercial applications!  Just click on the link below to read the full article from inhabit.com.

Condensing Furnaces In Attics?

Can you install a condensing furnace(90% + efficiency) in an unconditioned attic?  That is a common question we get here every winter at Environmental Heating & Air.  The short answer is technically yes you can.  But it should be noted that according to most leading HVAC equipment manufacturer installation manuals, it is recommended that condensing furnaces NOT be installed in unconditioned spaces.  The main reason being due to the freezing of condensation produced from normal system operation.  Condensing furnaces are high efficiency furnaces that cause condensation as part of the heating process.  Freezing temps in an unconditioned attic can cause the condensation to freeze, halting system operation, eventually causing the drain pipes to crack, equaling significant water damage to ceilings and/or any drywall.  Which is why a lot of HVAC service companies will not install condensing furnaces in unconditioned attics, it's just not worth the risk.  There are extra steps that can be taken to ensure condensation drain lines will not freeze, but even said steps still run a chance of failure resulting in an expensive situation for the homeowner.


The good news is that with current advancements in HVAC technology, I can't imagine that an unconditioned space compliant condensing furnace is far off.  Manufacturers today are making great strides in furnace efficiency at a very fast pace.  So let's hope more versatile high efficiency furnaces are in our near future!

Furnace Safety Awareness

I know it's been posted on here a few times about furnace safety in the past, but being made aware of the risks involved with cracked heat exchangers in furnaces can never be emphasized too much!  If you have a furnace in your home that's more than a few years old, you need to have a trained and certified professional inspect it and provide you with an overall assessment of your heat exchanger and burners.  You and your family's lives may depend on it!  If a crack or pinhole in the heat exchanger is found by a technician, they will then inform you of this find and advise you on how to proceed. 

Cracked heat exchangers can produce the odorless gas Carbon Monoxide, the silent killer.  Carbon Monoxide has no smell, color, or taste and can only be detected by CO detectors and specialized equipment.  There is only really two possible options after a crack is found, 1) replace the heat exchanger, or 2) replace the entire furnace.  Depending on how old the furnace is will determine the wisest path to take.  Most major brands of furnaces now offer 10 - 20 year heat exchanger warranties, in which case you should only be charged labor by the company you use to replace it.  At Environmental, we always work with the customer to figure out the most sensible option based on the age of the unit and your financial situation.

Remember, a cracked heat exchanger and/or deteriorating burners are a recipe for disaster!  Carbon Monoxide is very dangerous and at the very least you should have one CO detector present for every floor of your home.  Signing up for a Preventative Maintenance Plan will catch these dangers early and can also prevent them from happening in the first place, thus extending the life of your system.  Just give us a call and we would be glad to answer your questions and get you signed up today!

Dirty Sock Syndrome

During certain times of the year, like the present, when a heat pump may warm in the morning hours and then cool at noon and later hours, it can produce condensate from noon on which fuels organic debris decay resulting in microorganism growth in and around the evaporator coil for up to 16 hours — only to release odor and toxins during the next morning’s warming hours. Heat pump coil temperatures are often not sufficient enough to kill proliferating microbes. Those that may die simply serve as a future food source for continued proliferation.

A thorough coil cleaning will make a difference, but the problem will usually return.  That's why, in addition to regular cleanings by an HVAC professional, UV-C lights are a must in eradicating all microbial growth.  UV-C lights kill microbes of all kinds and types and, like bleach, disassociates their carcasses and other organic materials. UV-C lights produce very little heat, no odor, and leave no secondary contamination behind — and it operates continuously as long as the blower wheel is engaged, which means no build-up of microbial matter!  UV-C lights can now be purchased for relatively cheap and installation is usually quite brief.  Consult your local HVAC service provider today to get rid of that pesky dirty sock odor for good!
