Examining the Lifespan of Your HVAC System


In general, HVAC units tend to have a life expectancy of at least 15 years. Some well-maintained units can last up to 25 years, and only need to be repaired a few times. Your system’s viability is based on three key factors: its manufacturer (i.e., make and model), its components, and its upkeep. To ensure that your unit functions properly for the long haul, having a trustworthy contractor who specializes in central heating, duct installation, and AC repair in Murfreesboro to service your system really helps, especially if he or she offers a routine maintenance plan. However, things do happen. Here are a few determining factors on whether or not you should consider buying a new system.

Lifespan of HVAC System in Murfreesboro The Age of Your System

Even with the best care, your HVAC system will ultimately need to be replaced. The most obvious indicator of when to replace your system is its age. After about 10 years of normal usage, your air conditioner or heat pump will start to show signs of wear and tear. After 15 years, your furnace or boiler will too. When you decide to buy a new unit, take advantage of the situation by upgrading to an energy-efficient model. Look to purchase units with the ENERGY STAR logo, which can be 15 to 20% more efficient than conventional models.

Your System Needs to Be Repaired Often

Most problems can be avoided by having a routine maintenance plan set in place. For your part, simple chores, like switching out your system’s air filter every two to three months and cleaning your condenser’s intake vents, can help to extend the life of your unit. However, if your HVAC contractor is visiting your home more often than you would like him or her to, it’s time to buy a new system.

Your Home’s Moisture Levels

Your home’s humidity can negatively affect your HVAC system’s overall performance. Inadequate equipment and poor installation, coupled with uncontrolled humidity levels, can shorten the lifespan of any system. Also, if your ductwork is faulty or if it has leakage issues, you can experience abnormal moisture conditions when your system is heating or cooling.
