Signs That It's Time for a New HVAC System

Regular maintenance for your air conditioner will help you prolong its life and decrease operating costs, but everything ages and nothing lasts forever. So how can you tell when it’s time to replace your existing air conditioner, as opposed to just needing to fix it once again?

Air Conditioner Won’t Turn On

An extremely common problem, but just because your air conditioner doesn’t turn on, doesn’t mean that it’s time for a replacement. Check to make sure that no one else has turned the system off (the thermostat is set to COOL) and that your HVAC system didn’t trip the breaker circuit during the night or while you were out. Usually, a system that won’t activate is due to a lack of power or a thermostat setting.

Strange Noises

Rattles, banging, clanking, and whining are all unwelcome sounds when you turn on your air conditioner. The good news is that it’s typically not the end of the world. Loud noises all come from moving parts in your system. Loose screws, aging fan bearings, or a slipping belt contribute to the loud sounds in your system. A thorough cleaning and lubrication of parts will remove the majority. While loud noises don’t herald the death of your HVAC system, ignoring them can lead to other damage if left in disrepair, so get the system checked and repaired.

AC Shuts Off Too Soon or Too Late

For many homeowners, it certainly feels like a problem when the air conditioner refuses to shut off when the house is cold, or quits early while the house is still too warm. If you’re home isn’t quite as comfortable as it was last year, it’s probably not the air conditioner’s fault. First, check the location of the thermostat. Is it in a room that’s a hot or cold spot for your home? The thermostat needs to be located in a room that’s central, the mid-range point for temperature in your home.

Next, check to make sure that your HVAC system can breathe properly. Clean the air filters and check for brush and foliage that’s built up around the outdoor compressor. A lack of airflow can cause your system to operate for a long time as it struggles to keep up.

Pooling Water

Water pooling around your furnace or air conditioner may seem like it’s the end-times for the unit, but it’s usually not. Water condenses inside the unit regularly and a condensate drain line helps to divert it away from sensitive equipment. Check the drain line or drain pan to see if a blockage is causing water to leak out. Clear the condensate drain line and the problem will take care of itself.

High Utility and Repair Bills

Often, the clearest sign that it’s time to upgrade your system is by seeing how much money you’re spending on that system. If you find yourself spending a lot more on utility bills than you did last year, it could be due to maintenance issues but, if you had your system maintenance performed during the spring, it’s possible that it’s simply due to aging. Older systems, even at peak performance, have a hard time keeping up. Higher rates can reveal ventilation leaks, aging systems, and poor maintenance.

Recurring repair bills for constantly breaking systems are a clear sign that it’s time for an upgrade as well. As parts wear out, they’ll continue to break down. Eventually you’ll have replaced the entire system and at that point it will be better (in utility costs) to have purchased a new system.

The easiest way to tell if it’s time to change your system is based on age. If your unit is over 15 years old then it’s up for review. Even at peak performance, older systems are nowhere near as efficient as newer ones. Upgrading a system that’s more than 15 years old will improve cooling efficiency and help to regulate your home’s temperature better.

AC Refuses to Start

All of the repairs and maintenance in the world can’t account for a unit that refuses to start. In the end, if your compressor has gone out, the entire system will simply stay off. In this case, it’s best to replace the unit.
