When to Replace Your HVAC System
All HVAC systems are designed to operate at temperatures at or below 95 degrees and, ideally, last an average of 12-15 years. In Temecula, temperatures above 95 degrees are typical in the summer months, systems often begin to fail at between ten to twelve years. So, when should an HVAC system be replaced?
There are no specific 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 (which removes heat from the condenser) has failed. The cost to repair the 11-year old system is $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 at 10 SEER (or Seasonal Energy Efficiency Ratio) scale, which is relatively inefficient and often results in increased energy costs. In this case, Mechanical Pros Heating & Air would recommend replacing your HVAC system.
Compressor failure is typically an indication that an HVAC system should be replaced. Virtually every time a major component fails and the system is ten or more years old, replacement will be recommended — especially if the air conditioner uses R22 refrigerant, which is being banned by the EPA. Newer systems use R410, which is an environmentally sound refrigerant.
Modern air conditioners use 30% to 50% less energy to produce the same amount of cooling as mid-1980s 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.
Signs That an HVAC System Should Be Replaced
The heat pump or air conditioner is more than ten years old.
The furnace or boiler is more than 15 years old.
The HVAC equipment needs frequent repairs, and your energy bills are increasing.
The home has humidity problems.
The home is excessively dusty.
The heating or cooling system is noisy.
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 technicians will be provided to ensure installation is complete within a reasonable timeframe.
During system installation, Mechanical Pros HVAC Specialists will do the following:
Choosing a New HVAC System
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. Mechanical Pros 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:
