Heating System Install

Nowadays, most furnaces are incorporated with air conditioning systems that work together with the motor in the furnace that has to run whether in the heating or cooling mode. When considering repairing or replacing your heating and air conditioning system you are faced with a choice to replace parts or purchasing a new heater or a new air conditioner. To assist in this decision we have compiled this information for you to consider.

Three main determining factors

When faced with whether to replace your existing unit consider the life expectancy, state of unit, and efficiency.

Life Expectancy

Most units last only ten to twelve years. After that they break down and need to be repaired often. The parts at that point are not available or have long lead times from the factory and are often discontinued. Lifetime of unit may be shorter if close to ocean due to corrosion by high salt air content. Age of unit is also a major factor if older than ten to twelve years.


Units are rated SEER or Seasonal Energy Efficiency Ratio. The majority of systems installed before 1992 are 10 SEER or below and will drop in efficiency as the system ages. SEER ratings are a lot like miles per gallon in cars. The higher the rating, the more efficient the unit and the more money you will save. If your current system is over 10 years old, a matched system with a new 13 SEER unit could save you up to 38% annually on the amount of electricity used to cool your home.

State of Unit

The current condition of your unit whether you decide to replace or repair your heating and air conditioning unit should be considered. If the unit is old and has a history of problems or the repair quote or price approaches 40 to 50 percent of the value of the heating or cooling system, replacement would be a better decision in the long run.
