 General HVAC Frequently Asked Questions  How often should I change my air filters?For best performance of your system your air filters should be changed every three months but this can depend on the conditions in your home. If you typically have to dust your furniture once a week then you should stick to the quarterly filter changes. You can tell when to change an air filter by inspecting the back side of the filter, any discoloration on the back side (dirt) indicates the filter is fully loaded... |
 Air Conditioning Frequently Asked Questions  Why does my Air Conditioning run all day in hot weather? Assuming this is not a new symptom... this is a common complaint and can be attributed to two possible things. The first is that your system may have been designed correctly to meet the latest energy codes to perform at the highest efficiency. The other possibility is that it was not designed at all or was not sized properly in the first place. |
||
 Gas Furnace Frequently Asked Questions  Why is the LED light flashing on my furnace?If your furnace status LED is blinking a steady single blink this usually means the system is either in stand by mode or is receiving a call for heating or cooling. If the LED light is blinking rapidly more than once and then pauses and does more this usually indicates the furnace has an issue and some sort of failure or a safety device has tripped. |
 Heat Pump Frequently Asked Questions  Why does my outdoor heat pump have ice on it?Your heat pump will build up ice on the outdoor unit during the winter and this is normal. However, the ice should not build up and stay there, the system must automatically defrost the heat pump unit based on a time cycle, the outdoor temperature or presence of ice or in a different combination of the three. If your heat pump remain ice covered for more than a few hours... |

 How do I know if my Furnace is leaking Carbon Monoxide?  If you are even remotely concerned about carbon monoxide in your home then the smartest thing you can do is to go and buy a carbon monoxide detector from a big box store and plug it in any electrical outlet, one on each level of your home. These devices cost a little more than a cheap smoke detector and are well worth the expense for any home. |
 Why is there Water Dripping from the copper pipe on my Air Conditioner?  Water dripping from the refrigerant line set (copper pipe or tubing) is an indication of an improperly charged air conditioning system with our without insulation. The refrigerant levels in your air conditioning system is critical to proper operation and efficiency, both too little and too much refrigerant will cause poor operation, lack of capacity and lower operating efficiency. |
||
 How Does a Gas Furnace Hot Surface Igniter Work?  For the hot surface ignition type, after the control board has confirmed that the inducer fan is in fact running the heating system will apply high voltage to the hot surface igniter, some of these igniters are monitored by the board by checking to see if the device is actually drawing power. The board then switches on the main gas valve that allows gas to flow to the burner assembly. |
 How do I help Prevent Air Conditioning Systems Failures?  The best insurance against a broken air conditioning system is regular maintenance and while many of the parts in your air conditioning system are technical there are some things that a homeowner can do to make sure that they stay cool all summer long. 1. Make sure to clear the area around the condenser, the condenser is the outdoor unit |
||
 Why Can't I Buy R22 Refrigerant Air Conditioning Units?  The EPA has approved R-410A as a replacement alternative to R22, R410A is a blend of refrigerants or hydrofluorocarbons (HFCs) that does not contribute to depletion of the ozone layer, but, like R-22, it still can contribute to the causes of global warming. R-410A is sold under various names such as GENETRON AZ-20®, SUVA 410A®, Forane® 410A, and Puron®. |
 How can I help Prevent my Gas Furnace From Breaking?  Your furnace is really not anything like your other appliances in your home. Most people treat their heating and cooling systems as if they are an appliance and that is an unfortunate and expensive mistake. All heating and cooling systems, both residential and commercial, are large consumers of electricity, natural gas and in some cases fuel oil or propane. . |
||
 What do all the different efficiency ratings for a HVAC System mean?  For air conditioning the higher the "SEER" number the greater the efficiency and of course the greater your energy savings. At this time United States regulatory agencies require all new air conditioning products to have minimum of a 13 SEER rating. You will find that many equipment manufacturers carry lines of air conditioners with SEER ratings from 13 up to as high as 21. Heat Pumps are rated based on another system all together, the HSPF or Heating Seasonal Performance Factor... |

A dual fuel system is literally the combined installation of a both gas or oil furnace with an electric heat pump. For clarification the simplest description of heat pump is that when a heat pump is in the heating mode it is a air conditioning system in reverse. In the summer, a heat pump system acts just like an air conditioner and it absorbs the heat from your air and transfers it outside through the outdoor condensing unit. In the winter...
The term "variable speed" is in reference to the air handler or furnace fan motor or blower motor and while they are variable speed motors they are not variable speed in the true sense. Residential models are designed to use the variable speed to run at several pre-set speeds somewhat just like any other air handler or furnace. The difference is both in the motor and in how it gets up to that speed...
Humidity levels are sometimes very important as improper levels of humidity in your home can be unhealthful for some people and they do not even know what is causing their problem. Other issues such as damage to you furniture and hard wood building materials are also a a problem that occurs and homeowners are unaware of what...
