Is It Time to Replace or Install a New A/C System?

At Steve’s Plumbing & A/C – Oahu, we help you select the right system for your home’s layout and cooling needs — and we install it right the first time.
Here are some signs it may be time to consider a new A/C system:
- You’re not getting enough cool air, or it takes too long to cool down
- Your A/C is more than 10–15 years old
- Your electric bill is higher than normal
- You’ve had multiple recent repairs
- Your unit still uses older, inefficient refrigerants
Possibly the most obvious but important factor in deciding whether or not to replace your A/C unit is its age. Generally speaking air conditioning units near the end of their useful life around 12-15 years. If your A/C unit is around that age and experiencing issues, it’s probably time to have Steve's Plumbing & A/C Service - Oahu replace it!

Frequently Asked Questions About Air Conditioning Installation
Usually, it will take one to five days for a professional to install a central air conditioning system in your home. A/C replacements and projects with extensive ductwork, repairs, and/or installations will take more time.
Typically, a new air conditioner will cost around $2750 (more or less), but it will depend on the size of your home and the type of unit you need installed. Consider installing a new air conditioner when you buy a new furnace – by adding both units to your forced air system at the same time, you can save on costs by reducing time and labor.
Yes, usually any home can have central air. You probably will have to allow for ductwork and other design allowances, but it can be done. Before making the decision to have central air installed in your home, you should schedule an in-home consultation with a certified HVAC technician to get an idea of the total cost. Other cooling options for your home aside from central air include ductless splits and geothermal systems.
