A real call, start to finish

Out in the morning. Cool again that afternoon.

This is how one Casa Grande customer described a summer breakdown in July 2026, in their own words on Google.

Robert VandenBerg

  1. Morning

    “My air-conditioning went out probably early this morning and by the time I noticed it, it was about 86 in the house.”

  2. The call

    “The person answering the phone was extremely helpful and got back within less than a minute and told me that they could have someone out to my house somewhere between 3 and 5 PM the same day.”

  3. 3:15 PM

    “Oscar and Matthew showed up at approximately 3:15 PM. They diagnose the problem within a minute or two and had the replacement part installed and the air conditioner working within minutes.”

  4. After

    “I certainly will do business with them in the future and plan to use their service plan to evaluate my heating and air conditioning system on a yearly basis. Excellent business with excellent service.”

“Our A/C stopped and flipping the breaker started it back up. It needed to be checked and serviced. Our previous A/C company went out of business so I asked a neighbor who they used recently for HVAC service and they highly recommended Rush Air Conditioning and Refrigeration here in Casa Grande. I called and they answered the phone immediately. I scheduled an appointment. Mathew and Oscar came out on June 30th and quickly diagnosed a problem. They replaced 2 capacitors and checked the air handler. The charge for the service was very reasonable, and they were done in less than 2 hours.. The two service techs were very friendly, knowledgeable, and answered all our questions. We will definitely call Rush Air Conditioning with any issues in the future. I would give them 6 Stars if I could.”
