When it comes to fixing HVAC systems, there are numerous items to check for and that may be wrong. It can be a very frustrating experience trying to figure out what is wrong and then troubleshoot the potential problem. Although there are many conceivable items that can obstruct flow or cause your unit to be non-functional, here are some common heating problems and how to discover them.
Although it seems obvious when you first read it, having an iced-over pump isn't the first thing that pops into the minds of homeowners that have their heat stop working. Sure it's cold, but how could a heat pump freeze over?
If the pump's coil is ensconced in a light frost or ice, that isn't really a big deal. However, if the entire component is wrapped in ice, this is problematic and will need to be fixed as soon as possible to help conserve energy, evade impairment of the system, and return the lovely warm air that you've been missing out on.
Likewise, there could be some issues with the defrost timer, defrost sensor, the outdoor fan, or even a low refrigerant level. All of these items could be allowing your pump to ice over and should be checked.
Pilot Light is Out
Some individuals forget or don't even know that they have a pilot light that ignites their heating system. And although it doesn't seem likely, these pilot lights do go out on occasion.
For older homes, you will need to light the standing-pilot system manually. (Note: be very careful when doing this. If you are not confident lighting the pilot, please contact a professional.) For most new homes, they have some type of electric ignition.
If the pilot light still does not ignite, then there might be other issues to address, such as a bad (or cracked) gas valve, a low flame, or poor ventilation. If you cannot determine the culprit, it is suggested to contact a professional HVAC expert.
Incorrect Thermostat Readings
One frequent issue with older thermostats is a loss of calibration. You can get them re-calibrated, but there is a good realistic
chance that they can lose calibration once again after some use. The best solution for this hindrance is a digital thermostat, as they will not lose calibration and have a higher rate of accuracy.
Many Other Possible Items
There are numerous possibilities for low heat in your home and if it is not due to any of the common items above, then it's a good idea to contact a company that can troubleshoot the problem, as that can save you time as well as money.http://light.ezinemark.com/discovering-common-hvac-heating-problems-31f56254282.htmlhttp://www.energystar.gov/index.cfm?c=bldrs_lenders_raters.nh_hvac_contractors
