Safety is #1

Heating season is upon us and there are precautions everyone should take with their home heating systems, chimneys, and all venting for that matter.  When it comes to safety, we recommend  a professional inspection of these areas of concern.  Carbon Monoxide

Detectors or alarms as well as fire alarms should be present with fresh batteries in them.

Carbon monoxide is the leading cause of accidental poisoning deaths in America and is totally preventable.  (Centers for Disease Control) Carbon Monoxide or CO is a natural by-product of combustion from fuel burning appliances and is invisible to human senses.  It can cause brain damage or death.    CO alarms should be replaced every five to seven years to benefit from the latest technology upgrades.  To protect yourself and your loved ones from the threat of carbon monoxide and other dangerous gases, your HVAC technician should check the functionality of your carbon monoxide detector and any other power systems related to your detector including but not limited to:

  • Missing HVAC equipment parts
  • Clogged heater draft hood
  • Flue gas spillage


Heating systems should be inspected annually.   Just like that popular commercial states, “We know a thing or two, because we’ve seen a thing or two!”  You can’t imagine the things that can happen to HVAC equipment, from dead rodents to stray mylar balloons being trapped in a filter!

Chimneys and flues should be inspected for possible blockages annually, a certified chimney sweep can look at your chimney from all angles and are equipped to make any repairs necessary.  Below are items to consider in the maintenance of your heating system:

Inspecting the Heat Exchanger.  Without proper functioning, your heating system will not be able to run efficiently and may pose serious danger if it is compromised.

Cleaning your system’s burners

Inspecting all safety switches

Cleaning and inspecting of system’s blower motors, which may also include lubrication

Checking fan belts for any signs of cracking or breakage

Checking the thermostat to be sure your furnace is firing correctly.

Collecting flue gas samples to test your system’s efficiency level.

Replacing Air Filters that can become clogged.

Inspecting and assuring that all vents are properly installed

Replacing oil furnace nozzles and fuel filters

Checking Drain Lines

Heating & Cooling and Registers

Closing off heating or cooling registers is a common practice and most homeowners don’t realize this can be a costly mistake.  You may think it’s going to cut down on your heating or cooling bill when in fact, it does the exact opposite and actually increases your energy bills!  The kicker is that it could actually damage your furnace and shorten it’s lifespan.

It turns out that you also increase the chance for what is known as the static pressure inside the ductwork of  your home.  Higher static pressure is going to affect the airflow through your furnace and to your entire home.  If you have a standard blower motor on your furnace, higher static pressure is actually going to slow down the fan and decrease airflow to the entire house.  It can actually get low enough that the heat being created inside the furnace is unable to get out quickly enough and the furnace can overheat and hit the high limit, causing it to shutdown.  Repeatedly running on high limit is terrible for the furnace and will significantly shorten the life of the components, especially the heat exchanger.  The problem is similar in the summer with air conditioning – low airflow can lead to a frozen coil which could lead to liquid refrigerant making its way to the compressor which can kill that vital component in short order.  In other words, you can literally destroy your important and expensive heating and cooling equipment with something as seemingly harmless as closing a few vents.

If you have a newer, energy efficient furnace equipped with an “ECM” motor, a higher static pressure will cause the motor to use more energy to keep up with the extra pressure.  This results in higher utility bills along with shortening the lifespan of the blower.

If you have an older furnace, it may have a “PSC” blower motor that only operate at two speeds: on and off. So, when these motors work against extra pressure, the blower runs at a slower pace. And if the motor can’t pull as much cool air over the heat exchanger,  it will eventually overheat and crack, leading to thousands of dollars in repairs.

Other counter-productive issues include increased duct leakage, decreased comfort and increased energy use.  It’s always best to call a professional if you have the urge to close off any part of your home so you can be sure it makes sense and doesn’t cause damage that could cost you in the end.


  • Have a skilled heating contractor inspect your ductwork to ensure that it’s properly sealed and free of any leaks.
  • Have your furnace inspected annually and cleaned every few years to prevent blockages and other issues. If your ductwork also needs cleaning, now’s a good time to have that done as well.
  • If your furnace is in need of replacement soon, go with a newer, energy efficient model. Most new furnaces feature an annual fuel utilization efficiency (AFUE) rating near 95, whereas older furnaces are only half to two-thirds as efficient as their modern counterpart
