  • I Have A Heat Pump And My Electric Bill Was High. What Could This Mean?
    If the electric rates haven’t increased during that time period and you aren’t experiencing a colder than normal winter, this could indicate a problem with your system. Contained within the air handler on your heat pump system is a set of electric heaters that serve as a back up to your outdoor unit during the winter months. If the outdoor unit isn’t working properly, the electric heaters will run more frequently in order to meet the heating demand of the home. There are also controls involved with the operation of the electric heaters that may be malfunctioning and allowing the heaters to remain on even though there is no requirement for their operation. These problems may only be diagnosed by a properly trained and qualified HVAC Service Technician.
  • What Do I Do If I Smell Gas?
    Evacuate yourself and any other persons/pets from inside the home immediately. Using a phone located outside of the home, call your local gas utility and/or the fire department.
  • What Is Carbon Monoxide?
    Carbon monoxide (CO) is a colorless, odorless and toxic gas. The Environmental Protection Agency warns that at low levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include headaches, dizziness, disorientation, nausea, and fatigue. Many online resources and fact sheets are available to answer questions about carbon monoxide. The U.S. Consumer Product Safety Commission (CPSC) recommends that every home should have a carbon monoxide (CO) alarm. The CO detector will audibly alert the homeowner to the danger of the unacceptable CO level. For more information on Carbon Monoxide, click on the following links: www.cdc.gov &  www.epa.gov.
  • What Is Happening When I See Smoke Come Out Of The Top Of My Heat Pump?
    Every so often your heat pump has the opportunity to go into defrost either by timed or what we call on demand. When this happens it basically goes into air-conditioning mode and you will hear a “swish” sound. The four way valve on your system, what we call the “reversing valve” is switching the direction of hot gas into the coils to melt ice. This is normal operation and once ice is melted your system will go back to normal operation.
  • What Is Happening When I See Ice On My Unit?
    You may see “frost” or “ice” on the outdoor unit because the coil of the heat pump is colder that the air surrounding it and when that air is below freezing, frost or icing will occur, but should melt with in 1 ½ hours as this is the timing sequence most defrost controls use to check for this condition in our area.

Air Duct Cleaning in Cookeville, TN

Professional Duct System Services  

Many times we get calls and consumers report to us that they have rooms that are not comfortable.  Most of the time this scenario requires modification of the duct system. Luckily we provide air duct cleaning services in Nashville to provide a fix.

Many times, high power bills can be significantly reduced without changing equipment but with duct repairs that minimize or eliminate leaks.  If the RETURN air flow path (the path behind the filters that you change)  leaks, those leaks are robbing your system of comfort, capacity and significantly adding to un-necessary energy costs…month after month, year after year.


Do you notice dust, hot spots and cold spots, uncomfortable rooms? Call us today at (931) 345-2696 for a free Duct System evaluation in Nashville, TN.


What is our Duct System Evaluation Process

Our evaluations begin with a detailed, a room-by-room load calculation to determine proper air flows for each room, then air flow measurements, and then an evaluation of the existing duct system to determine how proper air flows should be designed to accommodate your home’s requirements.  Expect our evaluation to take approximately 2 hours.

Benefits of a Duct System Performance 

Duct systems contain ducts that provide a path to supply air and another path to return air.  Duct systems contain a primary (main) trunk, possibly secondary trunks and “run-outs” that connect to the vents that supply the air to the conditioned spaces.  

A duct system also includes a path for the air to return to the air handling device to be re-conditioned.  Other components of a duct system include filters and filter grills, diffusers (more commonly known as supply vents and can be located on the floor, walls, or ceilings).  Duct systems are designed to provide CFM (cubic feet of air per minute) air flows and at a targeted velocity (speed of air flow).  Size (proper sizing of each duct) has a significant impact on air flows.

How to Maximize Efficiency from your Duct System

All duct system components have a specific purpose.  And if your duct system is not properly designed, the poor design could be costing you additional $$$ on your energy bill or robbing you of comfort that your equipment is designed to provide for you. The most basic concept to remember is that your heating and air conditioning SYSTEM includes the installed equipment AND the ducts that are connected to it. 

Your duct system could be reducing the capacity of your installed equipment by 40% or more.  The best duct systems are those located inside the conditioned spaces (not in the attic or underneath the floors).  If ducts located in the conditioned spaces should have air leaks, leakage is not that critical since the leaks are occurring in air spaces that are already conditioned.  But…most homes do not have duct systems located inside the conditioned spaces.

Part of the capacity of your heat pump is alloted losses in air ducts located in hot attics or in damp and moist crawl spaces.  Great duct systems have air leakage rates less than 4%.   If the best systems have leakage rates of 4% or less, have you had yours checked to see what the leakage rates are with with your duct system(s)?  Saving money from properly installed, efficient duct systems will save you money and improve comfort regardless of age or efficiency of your equipment.  Leaky duct systems are one of the highest contributors of contaminants to indoor air quality.  Having your ducts cleaned is a band-aid approach to a more significant problem.

So.. is a rather mundane and un-exciting subject like duct systems in Nashville TN important to you?  I say yes.  And if you understood more about duct systems, I know you would agree.
