Choosing to invest in a new air conditioner is a big decision. Your AC unit will be responsible for keeping your home comfortable for the next ten years or more. If you're not familiar with how these systems work, it can feel like you're taking a big risk.

At Hollister, we understand that this purchase can be daunting. That's why our goal is to educate our customers and help them choose the perfect air conditioner for their home. We want you to feel confident and informed before making such a big investment.

In every consultation, we start by learning about your needs. If your current system isn't working, we know you need a replacement that won't break the bank. But it's important to think about your family's comfort and what hasn't been working well with your current system. Here are some questions we'll ask before getting started:


  • Do you have any big plans for renovating your home in the near future?
  • Are there any problem areas in your home that you would like to improve?
  • Are there any places that are too hot or cold, or areas with high indoor humidity?
  • Does anyone in your family suffers from allergies?
  • Have you considered installing a zoning system in your home?
  • Are you interested in upgrading to smart home technology can help you save money and energy?
  • Are there any parts of your home where you would like to keep noise from the HVAC system down?


Your choice of an AC Installer is an important decision. It can affect the safety and health of your family, as well as your budget and the value of your home. When it’s time to replace your air conditioning system, it pays to choose a responsible and established company with deep roots in the community it serves. Hollister is such a company.
