Common Questions About Replacing Air Conditioners
How do I know when to replace my old AC?
When you begin noticing your energy bills skyrocket whenever you’re using your AC or when it’s no longer cooling as fast as it used to – or at all – these are signs that you may need AC replacement and installation services.
How long does an AC usually last?
Most modern air conditioners can last up to 20 years when properly maintained. However, they will need repairs occasionally and will require maintenance.
What does SEER mean, and why does it matter?
SEER stands for Season Energy Efficiency Rating, which is something that all air conditioners have. The higher the number, the more efficient the unit is. It’s important to know your AC’s SEER as it correlates to your operating costs. Units with a higher SEER may cost more at first but will effectively save you money in the long run. We offer financing options to facilitate an easier process when choosing your new AC.
