What Our Customers are Saying
When To Consider an Air Conditioner Replacement
When given a choice most homeowners are going to want to repair a unit over replacing it. Unfortunately, there comes a time when repairing is no longer an option.
If you find you need someone out to service your system more than once a year, it may be time to replace it. The cost to repair will get to the point where it will supersede the cost to replace.
As a machine gets older it can struggle more to cool your home. This struggle can mean a higher bill. If you notice a spike in cost that’s not normal it may be time to replace.
Air conditioning units are specific to the dimensions of your home. If a unit is too small it won’t effectively cool the house. If you’re adding more square footage, your system may not be able to handle it and may require a replacement unit.
The average lifespan of an air conditioner is 10-20 years. As you get closer to that 20 year point, your AC unit may be on its last legs. It’s not a matter of care and repair at that point, replacing the unit may be your only option.
