All HVAC systems are designed to operate at temperatures at or below 100 degrees and, ideally, last an average of 12-15 years. In Los Angeles, temperatures above 95 degrees are typical in the summer months, systems often begin to fail at between eight to ten years. So, when should an HVAC system be replaced?
There are no set rules for replacement, as each system and situation is unique, so answering the following questions is a good place to start:
A typical scenario is provided below:
Your air conditioner stops working, and you discover that the condenser fan motor (the motor spinning the fan blade outside) has failed. The cost to repair the 11-year old system is $600-$700. If your HVAC system has not received routine maintenance, the condenser fan motor failure may be the first of many system issues. Additionally, 11 year-old systems are typically rated an 8 on the SEER (or Seasonal Energy Efficiency Ratio) scale, which is relatively inefficient and often results in increased energy costs. In this case, We would recommend replacing your HVAC system.
Compressor failure is typically an indication that an HVAC system should be replaced. Every time a major component fails and the system is 10 or more years old, replacement will most likely be recommended — especially if the air conditioner uses R22 refrigerant, which is being banned by the EPA. Newer systems use R-410A, which is an environmentally friendly refrigerant.
Newer air conditioners use 30% to 50% less energy to produce the same amount of cooling as 20-40 Year old air conditioners. Even if your air conditioner is only ten years old, you may save 20% to 40% on cooling energy costs by replacing it with a newer, more efficient model.
If you choose to replace your HVAC system, full installation typically takes six to eight hours; if ductwork replacement is required, the process may take a bit longer. If needed, multiple installers will be provided to ensure installation is complete within a reasonable time frame.
During system installation, Our Comfort Specialists will do the following:
Proper size and installation are critical to air conditioner efficiency. A unit that is too large will not adequately control humidity; conversely, a unit that is too small will not sufficiently cool a home during the summer months. Improper unit location or duct installation, as well as insufficient insulation, may greatly diminish efficiency. Pacific Coast Heating & Air’s HVAC Specialists can help you choose the right air conditioner for your home.
It’s important to choose an air conditioner with high efficiency. Central air conditioners are rated according to their seasonal energy efficiency ratio (SEER), which indicates the relative amount of energy needed to provide a specific cooling output. Many older systems have SEER ratings of 6 or less, while today the minimum allowable SEER is 14. Central air conditioners with the ENERGY STAR® label have SEER ratings of 14 or higher; for even greater savings, you may want to consider air conditioning equipment with even higher SEER ratings. Other important air conditioner features include:
