AC Replacement vs. Repair: When Is It Time?

One of the most common questions we get is whether a customer should replace or repair their air conditioning unit. Here’s how to decide:

Choose Repair When:

  • The unit is under 10 years old

  • The issue is minor (e.g., capacitor or thermostat)

  • Repair costs are less than 30% of a new unit

Choose Replacement When:

  • The system is over 12–15 years old

  • You’re experiencing multiple repairs in one season

  • Energy bills are steadily rising

  • The unit uses outdated refrigerant

In some cases, refrigerant leaks or a failing evaporator coil may be too expensive to repair, making a new air conditioning system the better choice.

We’ll assess your current system and provide clear recommendations to help you choose the best option.

Helping You Plan for Installation Costs

Investing in a new ac installation or air conditioner replacement involves upfront costs, but the long-term benefits make it worthwhile. At Pinnacle Heating & Cooling, we help you understand your installation costs and available options. Factors that influence cost include:

  • Size and type of the system

  • Whether ductwork needs to be installed or modified

  • Brand and efficiency rating
