The lifespan of an HVAC system depends on variable factors that affect how efficiently it operates. You can control some of the factors by the way you use your system and the demands that you place on it. Energy consumption is a good way to measure how hard your heating or cooling system works.
Just a few degrees can make a big difference in the electricity required to operate your system. For example, you spend up to five percent more for every degree that you warm your house above 70 in the winter.
The formula works in reverse for cooling, allowing you to save up to eight percent for every degree that you keep your temperature above 78. Consumption equates not only to electric bills but also to demands on equipment.
Some indicators that you can use to determine if you need to repair or replace your HVAC system are easy to notice. A system that is more than 10 years old is more likely to have operating problems than one that is younger, but age is just one thing to consider. If you do not run your system all the time, it may have a longer lifespan than one that is in constant use.
Possibly a more telling indicator is how often the system kicks on and off. If you notice that condition, it may mean that your system is undersized for the job that you ask it to do. Faulty ductwork may contribute to the condition. Keep track of the repairs that you have made over a period of time; bills are a painful reminder of what your system is costing you.
New noises, excess humidity and uneven distribution of conditioned air are other indicators of potential problems ahead. You can use the telltale signs to discuss a possible solution with a qualified HVAC contractor.
Recent changes in the air conditioning business may affect your decision. A new refrigerant was introduced in 2010 that does not deplete the ozone. New systems provide improved energy efficiency that can produce lower electric bills. Unless the problems you are experiencing are minor ones, you may get a better return on your investment by replacing your existing equipment.
Older systems produced a level 10 on the Seasonal Energy Efficiency Ratio (SEER), but that is no longer considered sufficient. The Department of Energy (DOE) now requires a minimum of 13 SEER, and your contractor can do some calculations to show how a higher SEER may reduce your energy use further.
The condition of the ductwork in your home is worthy of evaluation. In most homes, it is located in the attic where it is subjected to temperature extremes. Over the years, the seams and joints can dry out and allow leaks to occur. When you take a look at your attic, check the condition of your insulation.
If you decide to replace your system, choose a contractor who gives clients a load calculation to review. Tangible evidence of the proper size of a new unit may help you make an important decision. Your contractor can provide a warranty on new equipment that suits your preference.
