Even though you are attentive to your ventilation and air conditioning systems with proper maintenance and care, they probably won’t last more than about 15 to 20 years. Heat pumps average a little less due to year round use. Thermostats typically last the duration of the system, but because our new “Smart Stats” can save on operating costs, it would pay to upgrade to an energy saving thermostat if your current one is not programmable. These numbers seem consistent regardless of the climate you live in.
When it does come time to look at a replacement system, things have changed dramatically, with much improved efficiency and additional comfort options.
Get the Most Out of the Unit You Have
Replacement can be expensive, so do everything you can to get as much out of your unit as possible. Here are some suggestions:
- Keep the condenser clean and clear of shrubbery, leaves, etc.
- Keep your outside AC unit cool, so it doesn’t have to work as hard by planting shrubs between it and the sun,(maintain several feet clearance around unit)
- Change the filters every two months
- Do not cover the cool air vents with furniture. Allow the air to flow normally throughout your home
- Get regular annual maintenance checks and cleaning from a professional
- Use ceiling fans for improved circulation
- Use blinds and drapes to block intense sunlight
- Use a programmable thermostat to turn down the AC when you are away or at night when it is cooler. This saves a load on your unit and money on your energy bill
Some components can be replaced to extend the life of the unit, but once your unit is in the “final stages” age it might not be worth continuing to put money into it. Plan to replace it on your terms instead of having it stop working on the hottest day of the year.
