Hot weather can be tough without a dependable air conditioning system. Before the temperatures soar, check if your old HVAC unit is ready for another season.
How Old is Your System?
Even the best-maintained system won’t last more than 20 years. As your air conditioner gets older, its parts wear out, leading to frequent breakdowns and costly repairs. Even if it keeps running, expect higher energy bills.
Signs of an Aging System
A central air system rarely stops working without warning. Here are some signs your air conditioner might be on its last legs:
- Buzzing: This often means restricted airflow.
- Squealing: This could be a dry fan belt or a bearing needing oil. If the sound is from outside, it might be a refrigerant leak.
- Increased energy use: Old air conditioners can become very inefficient, driving up your power bills. Watch your energy bills closely.
- Bad smells: Dust or mildew can cause a dirty sock smell. Other odors might be from a clogged condensate drain leaking water.
How to Determine Your Air Conditioner’s Age
Knowing your system’s age helps estimate how long it will last. You might need to do some detective work to find out.
- Step 1: Find the label inside the front door of the unit. Look for a manufacture date. If it’s not clear, check the serial number.
- Step 2: Decode the serial number. For systems made in the 1990s, the first two digits often represent the week of manufacture, and the third and fourth digits indicate the year. For example, 1298 means the 12th week of 1998. For systems made in the 2000s, the last four digits usually indicate the month and year. For example, 0705 means July 2005.
Consider Efficiency
Older units are not as efficient as today’s HVAC systems, which offer more comfort at lower costs. Modern systems include energy-saving features such as:
- Variable-speed drive: These systems control the delivery of cooled air more precisely. They run slower and lower, eliminating abrupt on-off cycles.
- Higher SEER rating: The SEER (seasonal energy efficiency ratio) measures a system’s efficiency. The higher the SEER, the more energy it saves, similar to miles-per-gallon for cars. Manufacturers must meet a federal minimum of SEER 13, but top models can have SEER 20 or higher. Many older models in use today have a SEER 8 or less.
Maintaining a comfortable home during the summer requires a reliable and efficient HVAC system. If your unit is old and showing signs of wear, it might be time to consider a replacement. A new system, with modern energy-efficient features, can save you money and provide better comfort. For expert advice and HVAC installation, contact a professional HVAC contractor in Wellington.
