What are the signs it is time for a New Air Conditioner?
We’re here to help you navigate the increasingly complicated process of selecting a new AC unit! Like everything in life, there are usually signs when we need to replace our Air Conditioners in Boise!
Here are the four most common reasons for buying a new AC unit:
- Increased Utility Bills. If your utility bills are skyrocketing in the summer, this is a classic sign that your AC unit could be the culprit
- Excessive Service Calls & Repairs. A new AC system is on the horizon if you have to call an AC repair company like Top Shelf Heating & Air every summer to repair your system or recharge the lines.
- Age of Your AC System. While the Treasure Valley is booming with new growth, older homes have old AC systems. If your AC system is outdated or more than 10 years old, you may be paying too much and missing out on new advancements.
- Comfort is gone. Loud and inefficient AC systems cost you money but don’t help you stay cool in the summer! New technologies embrace the comfortable and quiet model!

1. What questions should you ask when buying a new air conditioner?
Here at Top Shelf Heating & Cooling, transparency is something we pride ourselves on, so we always tell homeowners to ask these questions when replacing their air conditioning unit:
- How do I know when it’s time to replace my AC unit?
- Are high-efficiency air conditioners worth the price?
- Should I replace my furnace at the same time as my A/C?
- What is covered under warranty with a new AC system?
- Should I finance a new AC unit?
2. What does air conditioning unit replacement consist of?
When you have your Boise AC replaced, we replace the unit and all its components, such as the air handler, supply lines, thermostat, and condensation drain lines.
3. How much does it cost to replace my AC?
New AC unit replacements in the Boise area cost an average of between $4,000 and $8,000. The prices vary based on the unit size, type (ductless split vs. central AC), and include installation.
4. When should you replace your air conditioner?
If you notice that your AC stops working, you don’t need to replace it immediately; a repair might fix the issue. However, if your AC unit is over 15 years old and you experience problems every year, it may be a sign that it’s time to replace your system. When the repair costs exceed $1,000, we tend to air on the side of replacing the AC unit.
5. What is the average lifespan for an AC unit?
Your home’s AC unit should last 15 years and can last much longer (20-25 years) when maintained. Regular maintenance and using the proper AC unit for your home’s size will increase the lifespan of your air conditioner. If you overwork your AC and fail to properly maintain it, the system may fail sooner.
