How to Choose the Right AC System for Your Concord Home

Eventually, even a well-maintained air conditioner will no longer cool your home efficiently. When that time comes, you’ll need to begin the process of looking for a replacement. 


It can be overwhelming trying to decide among all the many options available in today’s market. Fortunately, you can choose the best replacement system for your living space by following just a few key tips.


Choose a Cooling System Style

If you have a larger house, a full HVAC system might offer the most efficient way to heat and cool your home. In that case, this choice is a little easier.


For smaller living spaces, picking the best AC system for Concord, CA, homes involves looking at more options. You might want to switch from central air if you have a house with fewer rooms, for instance. A mini split system can offer more energy-efficient cooling and the ability to create distinct climate zones.


Alternatively, a heat pump offers year-round climate control. You can use the unit to heat your house in the winter and switch to cooling for the summer. Since the unit uses electricity to transfer heat to and from your living spaces, it features year-round energy savings over larger, traditional HVAC systems.


Select the Right Size or Capacity

When looking for the best AC system for Concord, CA, homes, cooling capacity is a vital concern. You can measure cooling capacity by British thermal units (BTUs). Most homes need an average of 20 BTUs per square foot. Multiply your home’s total square footage by 20 to determine the size of the air conditioner you’ll need.


For example, a 2,000-square-foot home will need an air conditioner with 40,000 BTUs. Your HVAC technician can provide a more accurate assessment of your home's cooling needs.


Check the SEER Rating

When looking at replacement air conditioners, the seasonal energy efficiency ratio (SEER) will tell you how much energy the unit uses. Most modern systems have SEER ratings that range from 14 to 16. 


For context, 26 is the highest or best SEER rating on the market. Air conditioners with higher SEER ratings typically come with higher upfront prices, but their long-term energy savings make them worthwhile.
