FAQ: How long will my air conditioner last?

The Short Answer

With proper AC maintenance, you can expect your air conditioner to last about 15 years. However, installing a new air conditioner can improve your home comfort AND save you money! Many of today’s highly efficient air conditioners can be up to 30 percent more efficient than systems that were installed just 10 years ago. By upgrading your aging system to a new high-efficiency AC, you can quickly lower your energy bills.

The Extended Answer

According to the Department of Energy, the average “lifespan” of a central air conditioner is about 15-20 years. Keep in mind, in order to make sure your investment keeps you cool for years to come, you need to purchase the best model and size unit for your home, have it installed properly, and schedule regular maintenance.

Choosing a Home Air Conditioner

Size is one of the most important factors to consider when shopping for a new air conditioner.  Properly sized air conditioners minimize operating costs, reduce humidity in your home during the summer, making you feel cooler, and reduce the temperature “swings” you may feel between rooms.

At GAC Cooling & Heating (Gaithersburg Air Conditioning & Heating), our comfort consultant will determine if there is a reason to believe your existing air conditioner is not properly sized for your home. Most often, the existing system capacity is correct. If, however, we are concerned that the existing system is not correct, we will measure your home and calculate the actual heating and cooling load on the home (calculation based on square footage, windows, walls, ceiling, floor plan, appliances, insulation, exterior factors, etc.). This will determine the recommended size of the equipment for your home.

Professional Air Conditioner Installation

Many air conditioners are installed incorrectly. This reduces their efficiency and also shortens their lifespan. That’s why in addition to choosing the right size air conditioner for your home, it’s also vital to have it installed professionally. A good HVAC contractor will be able to help you with all aspects of your air conditioner installation, including placement, sealing, and installation of all appropriate components such as:

  • Evaporator coil
  • Ductwork
  • Thermostat
  • Supply registers
  • Condensing unit
  • Etc.

Routine Air Conditioner Maintenance

Almost all AC manufacturers recommend annual inspections of their systems. In fact, many manufacturers will void your warranty if you fail to practice proper AC maintenance.

At GAC Cooling & Heating, we offer Peak Performance Maintenance Agreement plans to further protect your AC from inconvenient breakdowns, high repair costs, shortened equipment life, and other AC repairs. With the current high cost of energy, it’s extremely important to keep your system in good condition. When you neglect your AC, you pay for it, in terms of wasted energy and higher repair costs.
